How much is the leeches per jin? What's the use?

Leech is the common name of leech, China's earliest in the "Shennong Materia Medica" in the records of leech. Leeches have high medicinal value, with environmental degradation and predatory human hunting, the price of wild leeches has been very scarce. Let's take a look at the price and use of leeches.

1. The price of leeches

The price of leeches is mainly related to its variety and quality. At present, the price of leeches on the market is generally about 940 yuan per kilogram. There are also relatively cheap ones. It mainly depends on the origin and quality of leeches. The market price of leeches in different regions will also be affected to varying degrees. For example, the price of salt leeches is generally around 620 yuan per kilogram, and the price of alum leeches is generally 620 yuan per kilogram. However, clean water leeches are relatively more expensive, generally not less than 900 yuan per kilogram. In some areas, the average price of leeches is 600 yuan per kilogram, and in some areas, they can be sold for more than 1,000 yuan.

There are about 400 or 500 species of grasshoppers in the world. Most of them live in fresh water, a few live in salt water, and some are terrestrial and amphibious. They include species that feed on blood or body fluids, as well as carnivorous species that prey on small animals. The leeches we usually see in rice fields are generally Japanese medical leeches, which mainly suck human and animal blood. In nature, fish and other animal blood are the main ones.

II. Use of leeches

Leech has a high medical value, is a traditional Chinese special medicinal aquatic animals,"Bencao Huiyan" records leech "evil blood, blood stasis medicine also." Zhang Zhongjing, the sage of medicine, used it to eliminate pathogenic factors and strengthen body resistance, and used leeches to treat "blood stasis" and "water knot", showing its unique curative effect. Leech is generally dried products after brewing into traditional Chinese medicine, with the treatment of stroke, hypertension, blood stasis, amenorrhea, traumatic injuries and other effects. In recent years, it has been found that leech preparations have special effects in preventing and treating cardiovascular and cerebrovascular diseases and anticancer. In China, medical leeches were first used to treat blood stasis after finger replantation, and several cases were successfully treated, which was widely praised in China and abroad.

As the value of leeches continues to be discovered, their demand gradually increases, many areas have begun to breed leeches artificially. As early as 1984, Dr. Sawyer, an American leech expert, founded the world's first leech farm and biochemical medicine company in Wales, England. The hirudin and hyaluronidase produced by the company have been sold to Europe, America and Japan, and tens of thousands of live medical leeches have also been sold. France and Germany have now transferred hirudin genes into yeast and E. coli and genetically engineered them to produce cheap hirudin.

Although leeches don't look very good, they are actually very valuable. However, due to the high cost of breeding leeches, the yield is also relatively high, the leeches on the market are actually oversupply, the price is also in a downward trend, want to raise leeches friends, must investigate clearly in the line oh.
