(1) Abrasions, lacerations, stab wounds and cuts

Hand or foot abrasions caused by falls, sharp objects stabbing the skin, and blades or glass sheets cutting fingers are all difficult to completely avoid in daily life. Especially children who play with fur coats always have wounds on their bodies. These wounds may not be big, but if they are not treated, they are likely to become inflamed and fester, leaving ugly scars.

Aloe vera gel is very suitable for healing these wounds. Aloe has obvious bactericidal, anti-inflammatory, analgesic and hemostatic effects, especially promoting wound healing. Aloe gel treatment can obviously shorten the wound healing time without leaving scars.

Treatment: stop bleeding first, raise the injured part, dry the blood, and cover it with aloe gel to stop bleeding; If there is still bleeding, it may be a broken arteriole, or the personal coagulation mechanism is defective, other methods should be taken to stop bleeding quickly; After the wound stops bleeding, it can be washed with salt and boiling water to remove blood and foreign bodies, then dried and coated with aloe vera gel. Change the dressing (rub) 2 ~ 4 times a day, and the wound without secretion can be directly applied; Wounds infected with secretions should be washed with salt and boiled water, dried and applied; Deep, large-area wounds or wounds with many secretions and serious infections should be combined with oral administration or injection of broad-spectrum antibiotics.

(2) Contusion, crush injury, sprain and blast injury

The skin, subcutaneous tissue, muscles, muscle bonds, ligaments and joints of human body may be injured when they are hit, twisted or pulled by a large external force, which is generally called soft tissue injury. Causes subcutaneous small blood vessel rupture and bleeding, tissue cell inactivation, subcutaneous bleeding, oozing blood, serum overflow, local inflammatory reactions such as redness, fever, swelling and pain, muscle atrophy, dysfunction and other symptoms.

Aloe vera gel can dilate blood vessels, promote blood circulation, sterilize and diminish inflammation, decompose dead infected tissues and cells, and promote cell proliferation and regeneration. It has obvious curative effect on contusion, crush injury, sprain and blast injury.

Treatment:

1. Cold compress to cool down: After soft tissue injury, cold compress or ice cubes should be used immediately to cool down, so as to reduce bleeding, oozing blood or serum overflow and relieve symptoms such as redness, heat, swelling and pain;

2. Removing blood stasis and promoting blood circulation: After full cold compress (half an hour-1 hour), aloe vera gel can be directly applied to the affected area, and after 4 hours, aloe vera gel can be mixed with warm wine for hot compress. You can apply it several times a day, and each hot compress time can be a little longer.

(3) Burn (scald, burn)

Burns and scalds are skin tissue injuries caused by thermal burns. In addition to common high-temperature burns such as boiling water, flame and steam in daily life, it also includes chemical burns such as industrial strong acid and alkali, physical burns such as current radiation and nuclear energy. The severity of burn depends on the age of the patient, the cause, location, area and depth of burn, whether there is inhalation (respiratory) injury, compound injury and poisoning, and the health status before injury.

Burn depth is divided into three degrees:

Deep local expression sensation

1 degree

Erythema, slight redness, dryness, no burning sensation of blisters.

Shallow 2 degrees

There are blisters, and after peeling, the buttocks are wet and bright red, painful and allergic to fading.

2 degrees deep

There may or may not be blisters. After peeling, the bottom of the wound is slightly wet, light red or reddish in the middle white. After drying, you can see that the venules are relatively dim.

3 degrees

Wax white or brown, dry and tough, no blisters. Dendritic embolic vessels (usually electric burns) disappeared after scab drying.

A small area of water, fire and steam burns can be treated with aloe vera gel. Other burns need to be treated by a doctor after the wound is treated and the systemic symptoms are controlled, and then treated with aloe vera gel combined with antibiotics.

Aloe vera gel has a special effect on the healing of scald, which is shorter than the best scald medicine in China by more than one third, leaving almost no scar after healing. This is because aloe has outstanding bactericidal, anti-inflammatory and analgesic effects. In particular to promote wound healing.

Treatment:

1. Calm down. 1 degree, second-degree burn, after the cause of injury is separated and eliminated, immediately soak the burned part in tap water or clean water to fully cool down; Cooling for more than 30 minutes can reduce swelling and pain, and other symptoms will be alleviated; Strong alkali and strong acid burns should be washed with plenty of water, and those with pain difficulties can take painkillers orally to relieve the pain;

2. Apply medicine after debridement. 1 degree burn after the local temperature is fully cooled, dry the water and apply aloe vera gel (it needs to be thicker to further cool down). For second-degree burns, puncture or cut the blister with sterilized scissors and needles to discharge the liquid. The residual epidermis on falls and deep wounds should be removed. Seriously polluted wounds should be washed with clean water, then dried and coated with aloe vera gel. In winter, wrap it to keep warm;

3. change the medicine. 2 to 4 times a day, aloe vera gel can be directly applied to uninfected wounds. The infected wound should be washed with clear water first, and then coated with aloe vera gel. If the infection is serious, antibiotics should be used in combination, and the doctor should be asked to debride again. If there are many secretions, the wound exudate should be sucked out with sterile cotton wool in time.

In order to alleviate the pain of debridement and dressing change, analgesic tablets can be taken orally 15-30 minutes before dressing change.

note:

1. Consult a doctor as soon as possible, whether to inject antibacterial drugs and tetanus antitoxin, and infusion;

2. Generally, the wounded can take salty drinks orally;

3. The living environment of burn patients should be kept clean to avoid infection.

(4) prickly heat

Etiology: Due to high ambient temperature and high humidity, sweat is not excreted smoothly, causing inflammation of tissues around sweat pores.

Manifestations: It mostly occurs in hot summer and autumn, mostly in infants, and mainly occurs in forehead, neck, elbow socket, chest and back, groin, etc. There are two kinds of miliaria: white miliaria and red miliaria. Rash is common in newborns and children with fever. It is caused by sweat staying under the stratum corneum. It's a blister with the top as big as a needle. Thin-walled blister fluid is clear and easy to break, and there is no blush around the blister and no obvious symptoms. Erythrina is common in infants and children. Sweat stays deeper than prickly heat. At first, the skin turns red, and then there are papules or blisters as big as needles and millet, which are red and often have a dense itching or burning sensation. After a long time, prickly heat can evolve into eczema-like, that is, erosion-like, running water-like, sweat gland furuncle and impetigo can continue to occur.

Treatment: Take a bath frequently, change sweaty clothes in time, drink plenty of water and sleep in a ventilated and cool place. After washing the part with warm water, dry it, apply aloe gel solution (1: 3) 3-4 times a day, and use honeysuckle boiled water instead of tea, the curative effect will be better.

(5) solar dermatitis

Etiology: caused by too much ultraviolet radiation in the sun. The severity of dermatitis is related to the intensity of sunlight exposure, the length of exposure time, the size of exposure range and the strength of personal quality.

Manifestation: Dermatitis appears in the part exposed to sunlight. Mild erythema, moderate edematous erythema, clear boundary, local pain and discomfort, and blisters and bullae may appear in severe cases. Generally mild, but if not treated in time, a few days later, peeling or spots, freckles and other symptoms.

Treatment: After feeling sunburned, you should immediately apply aloe vera gel or aloe vera gel solution (1: 5 is suitable for tender and weak skin), 3-5 times a day until it is healed. Avoid sunburn again and wash the rash with alkaline soap before recovery.

(6) pruritus in winter (summer) and senile pruritus

Etiology: In winter, due to the cold climate, dry skin, and high temperature in summer, frequent use of skin cleaners leads to water loss and volatilization of skin (especially dry skin), which is lower than the necessary content. Due to the physiological characteristics of the elderly (too little water content in the epidermis, reduced sebum secretion), it is also easy to cause itching threshold to decrease and itching occurs.

Performance: More common in people over 50 years old with dry skin. Itching in winter begins in winter and is obviously aggravated when the temperature drops suddenly. Itching is particularly serious at night. If left untreated, it will often last until March and April of the following year, when the temperature is warm and humid. Summer itching mostly occurs in midsummer. The higher the temperature, the heavier the itching, and it will not be relieved or disappeared until autumn is cool. Senile pruritus mostly occurs in late autumn and winter. It itches all year round, and it gets worse in winter. Three kinds of itching are easy to occur in the front of the calf, the inner thigh and the back, and severe itching can occur all over the body. At first, the whole body looks normal, without any rash, or only dry skin, accompanied by bran-like white crumbs (no summer type), and after scratching, there are changes such as broken skin, bleeding and scab.

Treatment: Apply aloe gel solution (1: 3) externally, or apply aloe gel solution to the local area after bathing with aloe shower gel, 2-3 times a day, and avoid bathing with alkaline soap. Patients with pruritus in winter and the elderly should not take a bath too frequently, once a week. Usually, they should eat more food that nourishes yin and moistens dryness, abstain from alcohol and avoid spicy food, and those with severe itching at night can be present.

(7) Frostbite

Frostbite refers to the whole body or local injury caused by cold attack on human body. The degree of injury is related to cold intensity, wind speed, temperature, freezing time, local factors and systemic factors. Frostbite is divided into frostbite and non-frostbite. Frostbite is divided into local frostbite and systemic frostbite (frostbite); Non-frostbite is divided into frostbite and soaking hands (feet).

Local frostbite often occurs unconsciously, characterized by cold skin, needle-like pain, pale skin, and then numbness or unconsciousness. It was not until after rewarming that swelling appeared, and the scope and degree of frostbite gradually became obvious.

Degree and symptoms of frostbite

once

The chilblain skin is red or reddish, with slight fever or swelling, tingling and itching.

repeat

Swelling is obvious, forming blisters. The blister is serum-like or bloody, transparent or turbid, with obvious local pain, but local insensitivity.

Three-dimensional

There may be blisters, which are often smaller than second-degree blisters. At first, blisters were bloody liquids. With the gradual browning and blackening, the skin temperature is lower than normal, and the perception is dull, but the limb pain and edema are obvious. Some people's skin turns white at first, and gradually becomes dry and necrotic, and scab skin falls off to form ulcers. When there is thrombosis or infection, it can be wet necrosis.

Sidu

Deep tissue necrosis, and along to the muscles and even bones, the skin is purple-blue, or blue-gray, and the injured tissue completely loses its function and feeling. After the necrotic tissue falls off, the limb is partially incomplete.

Frostbite is common in the temperature below 10 degrees, mostly in the hands, feet, auricles and other parts. , local skin erythema, swelling, induration, itching and swelling of different sizes, sometimes blisters, superficial ulcers after rupture, secondary infection.

Foot soaking is caused by long-term immersion in cold water near freezing point, and its clinical manifestations and characteristics are similar to frostbite. Aloe vera gel is suitable for first and second degree frostbite, frostbite and foot soaking, and third and fourth degree frostbite and systemic frostbite require hospitalization.

Efficacy principle:

1. Cover the skin, avoid the invasion of bacteria and viruses, diminish inflammation and sterilize;

2. Promote local blood circulation;

3. Analgesia;

4. Infiltrate into skin tissue, promote cell regeneration and reduce scars;

5. Drain the purulent wound.

Matters needing attention when using:

1. First aid helps patients get out of the cold environment as soon as possible, take off cold and frozen clothes, shoes, socks and gloves, and keep warm all over; If the limbs are frozen stiff, put the injured limb in 4 1-42 degree constant temperature hot water for about 20 minutes until the skin is red and hot. For those with facial injuries, use 42-degree hot water and wet towel to apply local hot compress repeatedly, or use 70% alcohol to wipe and massage until the skin turns red. Give patients hot drinks, high-calorie liquid or semi-liquid and a small amount of wine to increase body heat. For more than second degree frostbite (including extensive second degree frostbite), you should consult your doctor whether to take orally or inject drugs to improve local circulation.

2. Local treatment (1) first-degree frostbite and initial frostbite. After rubbing the skin gently with ethanol, apply aloe vera gel, or apply warm wine mixed with aloe vera gel to the local area, and then wrap it with thick gauze or cotton pad. Small frostbite can be left unwrapped, but attention should be paid to heat preservation; (2) For second-degree frostbite and canker chilblain, the blisters should be punctured (or cut at the bottom) under aseptic operation, and the liquid in the blisters should be drained and sucked empty. After local disinfection with normal saline, aloe vera gel should be applied. Cover and wrap with sterile gauze to keep warm.

3. Change the medicine 1-4 times a day. For first-degree frostbite and early frostbite, it can be smeared according to the original method. For second-degree frostbite and canker chilblain, if there is secretion on the wound surface, it should be cleaned with normal saline and smeared. If there is no secretion, you can apply it directly.

Patients should be given drugs such as vitamin C, vitamin E and rutin every day to promote healing. Aloe vera gel can also be used for local wounds with controlled third-degree and fourth-degree frostbite, and the usage is the same as that of second-degree frostbite.

Microbial dermatosis in the second quarter

Caused by cell or virus infection, common ones are: impetigo, furuncle, carbuncle, paronychia, skin ulcer, diaper dermatitis, stomatitis and lip ulceration, toothache, wart, corns, etc.

(1) pustulosis

People call it "yellow water sore", and Chinese medicine calls it "pemphigus" or "abscess sore", which is highly contagious and can spread and infect others by itself. More common in summer, more common in infants.

Etiology: The main pathogen is Staphylococcus aureus, and a few are Streptococcus, or both are mixed infection. It is often caused by skin itching, epidermal scratches and bacterial invasion and reproduction.

Manifestations: Most of them occur in exposed parts such as face, limbs and infants' buttocks. At first, it was a small red dot, and soon it grew from half a grain of rice to the size of a broad bean or more in half a day to a day. The blister fluid was transparent at first, and then it became turbid and purulent. The blister wall is thin and loose, and pus is crescent-shaped and deposited under the blister. Bubble wall is easy to rupture and form erosion. After the pus touches the surrounding skin, a new pustule may appear, which can spread to the whole body in severe cases. The rotten surface will form a yellow pus scab after drying, and generally will not leave scars after healing. Some pustules recede in the center, and bacteria develop around them, looking like rings. The rash is itchy, and the natural process of each pustule is about a week. When the number of pustules is large, or the bacterial virulence is strong, patients may have symptoms such as listlessness, lack of food, or fever, and a few children may be complicated with acute nephritis.

Treatment: puncture all blisters and pustules with acupuncture, and remove the blister wall. Absorb blister liquid with absorbent cotton, apply aloe gel (it is better to apply aloe gel after washing with cold water and drying), 3-4 times a day, and take a bath with aloe shower gel or110000 potassium permanganate (available in pharmacies) every day. When itching, diphenhydramine can be taken orally to relieve itching. If you have fever or swollen lymph nodes, you should take antibiotics orally or by injection according to your doctor's advice.

(2) Furuncle, furuncle and carbuncle

Mao Mao's inflammation is purulent inflammation of the whole Mao Mao's inflammation.

Furuncle is an acute purulent infection of wool or sweat glands and their sebaceous glands.

Carbuncle is a deep acute suppurative infection (cluster furuncle) of several adjacent hairy stumps and sebaceous glands.

Etiology: The pathogenic bacteria of furuncle and carbuncle are staphylococcus, which is often caused by the invasion and reproduction of bacteria with damaged epidermis. In addition, anemia, chronic nephritis, malnutrition and diabetes can be complicated with furuncle and swelling.

Manifestations: Tinea and furuncle usually occur in the head, face, neck, arms and genitals. Carbuncle usually occurs in thick-skinned neck (aphtha) and shoulder and back (aphtha).

Both hairy sores and furuncles are red papules with hair follicles at the beginning, and the needles are as big as half a grain of rice; Folliculitis only infects a single hair, and the top of the papule quickly festers and scabs, and it heals after a few days.

On the other hand, furuncle is that the top of the papule does not fester, and bacteria develop to the deep part of furuncle and surrounding tissues, forming bright red or dark red nodules, which are about the size of pigeon eggs, with pain and tenderness. After that, the pus at the top becomes soft and there is a yellow pus suppository in the center. When mature, the pus suppository comes out to expel pus and cure it. Severe cases are accompanied by elevated body temperature, general malaise and swollen lymph nodes nearby.

Furuncle of sweat gland, also called hot furuncle or false furuncle, is caused by bacteria invading sweat gland and its surrounding tissues. It is common in hot weather, especially in children's head, face, neck and forearm. It is characterized by some reddish nodules which are big as mung beans and big as fingers, and are hemispherical. Redness, swelling, heat and pain are not as obvious as furuncle. After a few days of wrapping, it softened and festered, discharged pus and healed, and there was no pus suppository. Usually some subside and heal, and some continue to happen.

Carbuncle, initially manifested as red inflammatory infiltration area of flaky sauce, is higher than the body surface, with hard texture, edema and unclear boundary with normal tissue. After about one to two weeks, there are many small pus heads in the skin in the central area, which are honeycomb-shaped after rupture, and then the central part collapses, such as "crater". Severe pain in the affected area, often accompanied by high fever, chills, general malaise, loss of appetite and so on.

Treatment: After washing and drying the rash, apply aloe gel 3-4 times a day. If you have symptoms all over your body or boils on your head and face, you should add antibiotics and rest.

It is forbidden to squeeze the boils in the mouth-nose triangle, otherwise it will easily lead to intracranial infection and various serious diseases, and the mortality rate is high, which should be paid great attention to.

For the treatment of carbuncle, aloe vera gel can be applied 3-4 times a day after cleaning the rash surface in the early and middle stages and after ulceration (if there is no secretion on the rash surface in the healing stage, it is not necessary to clean it before taking the medicine), and if necessary, it can be combined with painkillers and other painkillers to relieve pain. Antibiotics should be taken orally or injected under the guidance of a doctor; Patients with large lesions and poor therapeutic effect must be operated.

(3) paronychia

Etiology: paronychia is an inflammation caused by staphylococci invading the nail margin or soft tissue near the nail bed. It is usually caused by minor local trauma (stabbing, barb or ingrowth of nails).

Manifestation: The nail margin soft tissue is red, swollen and painful, and purulent secretion can overflow after several days of compression. If tendrils and adjacent nails are inflamed, nails are swollen, nails are dark, or faint yellow-green, and tenderness is obvious, nail bed inflammation is complicated.

Treatment: soak aloe gel solution (110-1/20) in warm water (cooler water may be needed), or clean the affected area 3-4 times a day for about 20 minutes each time, then dry it and apply aloe gel.

Manager's Note: The original text in the message is aloe gel solution. I think it can also be soaked in aloe shower gel, and the effect may be better. In fact, Jianyi tea is rich in vitamin C, which has anti-inflammatory, analgesic and detumescence effects. You can also try its solution. Please let me know if you have any feedback (0 10-86469744).

(4) Skin ulcer

Local defect erosion on the surface of skin or mucosa.

Etiology: skin injury caused by various reasons, often accompanied by bacterial infection.

Manifestations: round, oval, or plastic, erosion, exudation, peripheral edema, subjective itching and pain.

Treatment: Apply aloe gel after cleaning and drying, or apply aloe gel after cleaning and drying with aloe gel solution (1/50), 3-4 times a day. Patients with large area ulcer can take two tablets of vitamin B6, one tablet of vitamin C and one tablet of vitamin A orally, three times a day.

Erosion and ulcer are all caused by primary skin injury, which has many reasons. If aloe vera gel is not effective, please see a doctor and prescribe the right medicine.

(5) diaper dermatitis (rash)

Babies who use diapers often have dermatitis in perineum and buttocks.

Etiology: Children's perineum and buttocks skin are damp and hot due to various factors, and various stimuli (urea, friction, diaper acid and alkali, stool acid and alkali) cause dermatitis.

Manifestation: It is common in diaper wrapping parts, such as buttocks, upper inner thighs, perineum, etc. At first, the skin was red and the edge was clear; If not treated in time, tiny papules, blisters and pustules may appear on the flushed skin, which will become erosion and running water due to friction. At this time, bacterial infection is prone to occur.

Treatment: at first, when only the skin is red, rinse with aloe gel solution after defecation, dry it and sprinkle with talcum powder. If there are papules, blisters, pustules or erosion, you can first scrub with aloe gel solution (1/50), and then apply aloe gel after drying, 1-3 times a day. If there is no secretion in the affected area, there is no need to scrub when changing the medicine. Diapers should be made of cotton cloth with strong water absorption, which should change with moisture and keep dry. It is forbidden to wash diapers with alkaline washing powder.

(6) stomatitis and lip ulcer

1. stomatitis: stomatitis is chapped, eroded and ulcerated in the oral cavity. There are two reasons: oral local reasons and general weakness. Often due to colds, gastrointestinal weakness, vitamin B and C deficiency.

Stomatitis includes mucositis, ulcerative stomatitis and herpetic stomatitis.

Mucosal properties are mild in stomatitis, which is characterized by large swelling and swelling of mucous membrane in oral cavity, increased saliva and burning sensation in oral cavity. I hope the oral pollution caused by tooth decay or alveolar abscess, the stimulation of dentures and other appliances, and the influence of smoke, alcohol and chemicals.

Ulcer is a serious and common disease in stomatitis. It is a kind of burning ulcer with a long course of disease and repeated attacks. The ulcer seriously affects the digestive function and language function of patients, such as eating, chewing and swallowing. Severe syndrome affecting multiple systems of the whole body.

2. Oral ulceration and herpetic stomatitis: caused by herpes simplex virus, which mostly occurs after warm disease, so it is called hot sore.

Manifestation: At first, the affected part felt burning, itching and swelling, and then the skin (mucosa) flushed, and groups of blisters as big as mung beans appeared. Erosion and exudation after rupture, gradually drying and scabbing, scabbing off and healing. If infected with pyogenic bacteria, it will be swollen and painful, or accompanied by swollen lymph nodes nearby, and the recovery time will be slightly longer.

Treatment: After gargling or cleaning the affected part, apply aloe gel 3-4 times a day. Those who have suppuration or swollen lymph nodes nearby and herpes often recur can take antiviral drugs orally under the guidance of a doctor. Pay attention to the hygiene of the oral cavity. During the onset, do not eat shrimp and crabs, eat less sucrose, pickle, smoke and bake all kinds of fried, roasted seeds and nuts, spices, alcohol and spicy food. In addition, herpes simplex (heat blister) also occurs around nostrils, eyelids, cheeks and genitals, anus and buttocks, with the same symptoms as herpetic stomatitis. Aloe vera gel can also be used in this way.

(7) toothache

Toothache is a common disease, usually caused by dental caries. In the early stage of dental caries, only the color changes, and the teeth can hardly feel pain, but if it develops into dentin and pulp, it will cause inflammation and pain symptoms.

Aloe vera gel has the functions of analgesia, sterilization, anti-inflammation, neutralization of bacterial toxins, and can eliminate or slow down toothache.

Usage: After brushing your teeth or gargling, apply aloe vera gel to the toothache. Aloe vera gel will be consumed quickly and needs to be applied continuously until it is completely anti-inflammatory.

Aloe vera gel can only be used to relieve inflammation and pain when it is inflamed. Immediately prevent and gradually cure dental caries. Please use Perfect Aloe Toothpaste as soon as possible. Really.

(8) Warts and corns

Warts are caused by virus infection, and the cuticle of the skin thickens and bulges, which can be divided into several categories according to the location and size. The general wart will not feel pain and itching.

The formation of corns is due to long-term intense external stimulation or oppression (such as wearing tight shoes), which makes the skin of toes and heels keratinized and become as hard as bones, which will stimulate nerves and cause pain. Aloe vera can kill viruses, soften keratinized skin, promote wound healing, and has a good effect on the cure of warts and corns.

Treatment: Before taking the medicine for the first time, soak the affected area with warm water to soften the cuticle, scrape off the cuticle on the surface with a sharp blade, and then apply a thick layer of aloe vera gel. After cleaning, change the dressing 3-4 times a day. Generally, the corns will fall off layer by layer after seven days, but the treatment of warts requires patience and takes some time to remove warts. After warts and cornea fall off, aloe vera gel should be applied to reduce scars.

Efficacy principle: All the above skin diseases are caused by bacteria or viruses invading the skin. Aloe vera gel has outstanding curative effect on these diseases. Aloe vera has outstanding bactericidal, anti-inflammatory and cytotoxic effects, which can effectively kill pathogenic bacteria such as staphylococcus and hemolytic streptococcus B, and has analgesic and wound healing effects.

Section 3 Insect Dermatosis

Common insect skin diseases include bee stings, mosquito bites and centipede bites. Aloe vera can neutralize toxins, has antibacterial, anti-inflammatory, analgesic and antiallergic effects, and is suitable for treating insect dermatoses.

(1) mosquito bites

Performance:

1. Skin lesions are more common in exposed parts.

2. Edema papules, wheals or petechiae are the most common lesions, and insect bites are often seen at the top of the rash.

3. Subjectively itchy or stinging

Generally, it can subside in three to five days to the weekend. If there is secondary infection, it can be delayed for a long time and may be accompanied by local lymphadenopathy.

Treatment: Apply aloe vera gel immediately after mosquito bites, which can quickly relieve itching and reduce swelling; If dermatitis occurs after scratching, avoid scratching and rinse with soap and hot water, otherwise dermatitis will be serious; After washing with cold boiled water and drying, you can apply aloe gel 3-4 times a day.

(2) bee sting

It is a local and systemic symptom caused by the stinger or venom of bee tail entering human skin.

Manifestations: local swelling, small bleeding point in the center of stab wound, conscious itching and severe pain; When you are stabbed by a swarm of bees in many places, serious people may have nausea, weakness, fever and other general malaise; If you are stung by a bumblebee, you may go into shock and even be in danger.

Treatment: After being stung by a bee, first check whether there is a broken stinger in the stung area. If there is, you can pull it out with tweezers or pick it out with a sharp knife, and then squeeze out 2-3 drops of blood (preferably cupping to suck out the venom). The venom of wasps is alkaline and can be coated with vinegar. Bee venom is acidic and can be applied externally with soda water or soapy water; After drying, apply aloe vera gel 4-5 times a day. If the pain persists or there is obvious systemic allergic reaction, please take medication or oral chlorpheniramine and painkillers three times a day.

(3) centipede bite

The first pair of feet of centipede have developed claws and poison glands, which can pierce the skin and release poison to hurt people.

Manifestation: Two little red dot appeared at the bitten place, which quickly became red and swollen, accompanied by severe pain or itching, and sometimes lymphangitis appeared.

When the poisoning reaction is serious, there may be systemic symptoms such as fever, headache, palpitation and even cramp. Children who are bitten may be life-threatening. We must pay close attention to it.

Treatment: After being bitten, the blood of the wound should be squeezed out as soon as possible (it is best to draw out the venom by cupping), then washed with soapy water or soda water, dried and coated with aloe vera gel, 4-5 times a day. When the pain is severe, you can take oral painkillers or accept local injections from doctors; Children or children with obvious systemic symptoms must be treated by doctors.

Section 4 Beauty

(A) aloe vera gel beauty

Aloe vera gel has the functions of activating cell vitality, delaying skin aging, astringing, harmonizing skin, nourishing skin and caring skin. It is a beauty product.

1. Activate cell vitality and delay skin aging A. Components such as calcium isocitrate in aloe can dilate capillaries, promote microcirculation, promote substance metabolism of skin cells and enhance cell vitality. B. Free radical scavenger The superoxide dismutase, peroxidase, vitamin C, vitamin E and *-carotene contained in aloe can scavenge free radicals that cause cell aging and delay skin cell aging.

2. Convergence, harmonizing the natural convergence of aloe vera, can make the skin firm and meticulous, and prevent the skin from sagging and wrinkling; Mucin can regulate the moisture and oil of the skin and keep the skin in a balanced state.

3. Aloe vera, which nourishes the skin, contains sugars, amino acids, vitamins, minerals, enzymes, organic acids and water, and is an essential nutrient for the skin. These components in aloe have small molecules and strong permeability, and can enter the inner layer of skin.

4. Protect the skin A. Experiments show that aloe can form a skin film on the skin surface, which can effectively lock moisture; B. Aloe can absorb some ultraviolet rays and has a sunscreen effect; C. Aloe has the functions of sterilization, anti-inflammation, and neutralization of microbial toxins, effectively preventing skin diseases caused by various microorganisms.

Usage: After washing your face, dilute the aloe gel with water to a ratio of 1: 3, and evenly apply it to your face, 2-3 times a day. It is not advisable to apply it too thick during the day, but it can be applied thicker before going to bed (as a nutritional mask).

Chloasma and freckles

Chloasma, also known as liver spot, is a pigmented skin disease that occurs on the face. Female pregnancy, menstrual disorder, pelvic diseases, oral contraceptives, some consumptive diseases (such as tuberculosis, cancer, chronic alcoholism, etc. ) Anger in peacetime can occur. It is characterized by yellowish brown or brown patches on forehead, zygomatic face, nose and upper lip, with different sizes, clear edges, smooth surface and no conscious symptoms. Sometimes chloasma merge with each other to form a butterfly-like appearance.

The appearance of freckles may be related to heredity and sunlight exposure. Most of them begin to appear at the age of 6-7, often on the face, sometimes on the neck and back of the hand. They are needle-to-mung bean-sized yellowish brown or light black spots, distributed in groups or scattered, with smooth surfaces and no conscious symptoms. After intense sun exposure in summer, the color deepens and the number increases, while the color fades and the number decreases in winter.

Chloasma and freckles are naturally easy to appear, but they are more likely to appear after ultraviolet irradiation. Cosmetic allergy, mental stress, partial eclipse, liver, kidney and other visceral dysfunction and other reasons, so that melanin in the body is deposited in the body after production, can not be discharged smoothly, may be the cause.

Sunscreen and decoloration are the key to freckle removal, and aloe vera gel is beneficial to freckle removal because:

1. Aloe contains aloin, anthraquinone, cinnamic acid and other components, which can absorb some ultraviolet rays and isolate some sunlight.

2. Amino acids, organic acids, aloin and other components contained in aloe gel can inhibit tyrosinase activity and hinder the formation of melanin.

3. Aloe can enhance microcirculation, promote cell metabolism, and gradually remove pigmentation in the skin.
