Medical leeches are leeches, and their saliva contains hirudin, which can effectively prevent blood coagulation. Therefore, in clinical treatment, some doctors use this feature to eliminate patients' local congestion and swelling, and also relieve high blood pressure. Let's take a look with this site! What's the use of medical leeches?

At present, there are only two kinds of leeches that can be used for treatment in the world, namely Japanese leeches and European leeches. In the ancient Shennong Materia Medica, there was a record of leeches treating diseases. At that time, doctors would put leeches on suppurative wounds, and use the blood-sucking characteristics to completely suck up purulent blood, so that the wounds could heal faster. But at present, the demand for medical leeches is still greater abroad, and it must be alive.

The purpose of modern medical leeches is mainly to remove some local congestion or swelling after operation, such as finger transplantation or plastic surgery, which can effectively reduce the probability of tissue necrosis. Moreover, the saliva of medical hirudin not only contains hirudin, but also histamine which dilates blood vessels, so it is also very beneficial for cardiovascular and cerebrovascular diseases such as hypertension and can play a very effective role in relieving it.

With the development of scientific research, the use of medical leeches is gradually increasing, especially abroad. As early as 1984, American leech experts founded the first medical leech breeding company, and also produced a large number of hirudin and hyaluronidase, which were widely sold in Europe and Japan. Hirudin is the most effective natural anticoagulant at present, which, in the words of traditional Chinese medicine, can promote blood circulation and remove blood stasis.

However, Japanese medical leeches are also cultivated in China, but the number is relatively small. It looks different from ordinary leeches, with a slightly flat body and longitudinal stripes, with dark brown spots near the stripes and the widest spot in the middle. Blood-sucking capacity can exceed 6 times of its own, comparable to fleas, which is harmful to people in dogs and fleas? How much is a medical leech?

The price of a leech reached its peak in February-April 1991, reaching the highest level of 15 yuan/kg, and rose to 27 yuan/kg in the second half of 24. According to the information provided by Chinese Medicine Network, the price of clear parallel imports is 85-9 yuan/kg, while that of salt parallel imports is 6 yuan/kg, which seems to be a very potential development project.

Autumn is the peak season for the sale of leech seedlings. About 2, leeches are planted per mu, which costs about 3, yuan, and the output is about 8-1 kilograms. Many drug farmers will bid for it, and it is best not to introduce leeches under 2 grams, because the two-year-old leeches are fertile again, and they should not be introduced in June, when leeches are likely to have laid eggs.

Leech has high medical value, and it is easy to breed, but it still needs breeding technology in place to succeed. Remember not to be impatient.
