Green coffee is an evergreen shrub or small tree of Rubiaceae, with opposite leaves, leathery and oval; Peanuts in leaf axils, white; Berry oval, deep red, containing two seeds. Coffee is native to eastern tropical Africa. According to the size of coffee beans, it can be divided into large, medium and small grains. Small-grain fruit coffee is suitable for planting in the highlands at an altitude of 600 ~ 1200m, which is relatively resistant to low temperature but weak in disease resistance. Chinese coffee is suitable for planting in areas with an altitude of 300~700 meters. It is not resistant to drought and wind, but it has high yield and good quality, and the fruit is not easy to fall off after ripening. Big fruit coffee is suitable for planting in lowlands below 300 meters above sea level, which is drought-resistant, pest-resistant and has a strong taste. Chlorogenic acid in green coffee bean extract is a phenylpropanoid compound produced by shikimic acid during aerobic respiration, also known as coffee tannic acid, which is composed of many isomers. Chlorogenic acid is easily soluble in water, ethanol and acetone, slightly soluble in ethyl acetate, and appears as a pale yellow solid at room temperature.

It has a particularly strong bitter taste and stimulates the central nervous system, heart and respiratory system. Moderate caffeine can also reduce muscle fatigue and promote the secretion of digestive juice. Because it can promote renal function, it has diuretic effect and helps the body discharge excess sodium ions. But too much intake can lead to caffeine poisoning.

The effect of green coffee

Weight loss effect

Animal in vitro studies have proved that chlorogenic acid in green coffee can irreversibly inhibit the hydrolysis of glucose -6- phosphatase, reduce the decomposition of glycogen and the absorption of exogenous glucose, and promote the decomposition of fat in vivo to replenish energy, thus achieving the effect of reducing fat.

Hypotensive effect

Chlorogenic acid has obvious antihypertensive effect, stable curative effect and no toxic side effects.

Antitumor effect

Has remarkable curative effect on preventing and treating nasopharyngeal carcinoma, remarkable curative effect on treating tumor, and has the characteristics of low toxicity and safety; Japanese scholars have studied the antimutagenic effect of chlorogenic acid and revealed its preventive effect on tumors.

Tonify kidney and enhance immunity.

Anti-oxidation, anti-aging, anti-aging of bones, etc.

Has antibacterial, antiviral, diuretic, cholagogic, blood lipid lowering and fetal protection effects.

health foods

It can make health food sweet and delicious, and has the characteristics of clearing away heat and toxic materials, caring skin and moistening skin, and eliminating excessive alcohol and tobacco.

Centella asiatica is a creeping perennial herb. Alias: Eighteen Hills, Collapsed Bowl, Horseshoe, Leigonggen, Fangzhouzi, Baimu, Luodingda, etc. Born in wet wasteland, in villages, roadsides and ditches. Stems grow on the ground and take root at nodes. Leaves alternate and petioles are long; Leaf blade is round or kidney-shaped, 2~4 cm in diameter.

Flowering in summer; Umbellies are head-shaped, with 2~3 axillary leaves, and each inflorescence has 3~6 sessile florets; Flowers are red and purple. The fruit is small and oblate.

Rhubarb, also known as general, is a general name for many perennial herbs of Rheum in Polygonaceae, which are generally planted with short roots. Rhubarb has triangular big leaves and thick petioles. Flowers are small and clustered into inflorescences, ranging in color from green and white to rose red. In the literature of China, "rhubarb" often refers to rhubarb; But in Europe and the Middle East, rhubarb often refers to several other varieties.

Green tea is one of the main tea leaves in China, which refers to a beverage made from the new leaves or buds of tea trees without fermentation, and through the processes of enzyme fixation, shaping and drying. The color of the finished product and the brewed tea soup retain the green style of new tea. Drinking green tea regularly can prevent cancer, reduce fat and lose weight, and also reduce the harm of nicotine to smokers.

Without fermentation, green tea retains the natural substances of fresh leaves, and contains many nutrients such as tea polyphenols, catechins, chlorophyll, caffeine, amino acids and vitamins. These natural nutrients in green tea have special effects of anti-aging, anti-cancer, sterilization and anti-inflammation, which are beyond the reach of other teas. Green tea is a kind of tea made from suitable new shoots of tea trees through typical technological processes such as enzyme fixation, rolling and drying. Its dry tea color and brewed tea soup and tea leaves are mainly green, hence the name green tea. Green tea is made from fresh leaves that have been picked, killed by various oxidases at high temperature, kept green, and then kneaded and dried. Clear soup and green leaves are the same characteristics of green tea quality. China produces all kinds of green tea. Henan, Guizhou, Jiangxi, Anhui, Zhejiang, Jiangsu, Sichuan, Shaanxi (southern Shaanxi), Hunan, Hubei, Guangxi and Fujian are the main green tea producing provinces in China.
