How much is the leech per jin?

Abstract: leech is a traditional Chinese special medicinal aquatic animal, which has the effects of treating stroke, hypertension, clearing blood stasis, amenorrhea, falling injury and so on. In history, it is mainly natural fishing. In recent years, due to the abuse of pesticides, chemical fertilizers and the environmental pollution caused by industrial and agricultural "three wastes", the wild natural resources have decreased sharply, and its market demand potential is huge. Next, let's take a look at how much leeches cost per jin.

Leech is a traditional Chinese special medicinal aquatic animal, which has the functions of treating stroke, hypertension, clearing blood stasis, amenorrhea, falling injury and so on. In history, it is mainly natural fishing. In recent years, due to the abuse of pesticides, chemical fertilizers and the environmental pollution caused by the "three wastes" of industry and agriculture, wild natural resources have decreased sharply, and its market demand potential is huge. Let's take a look at how much leeches cost per jin.

How much is the leech per jin?

Leech is not only a high medicinal price, and a wide range of applications, the market supply is also very tight, its price is rising year by year, the current processing of leeches for 600 million 650 yuan per jin, salt water goods leech about 450 million 500 yuan per jin, alum leech market price of about 430 million 450 yuan per jin, at the same time, leech later market price is expected to remain strong.

The historical price of leeches

At present, the market demand for leeches is increasing year by year, wild leech resources are exhausted year by year, local inventory supply is weak, and the gap between supply and demand is as high as more than 50%. These factors are the main reasons for the sharp rise in leech prices year after year. A survey of 17 professional markets of traditional Chinese medicine shows that since 2000, the price of leeches has risen sharply year after year, from 150 yuan in 2002 to 160 yuan in 2003, 170 yuan in 2004, 180 yuan in 2005, 190 yuan in 2006, 200 yuan in 2007 and 230 yuan in 2008. From 2009 to 2011, the price of leeches soared continuously, rising to 380 yuan in 2009, 740 yuan in 2010, and 800,820 yuan in 2011.

Price factor of leeches

1. Serious river pollution: leeches grow in rivers, lakes, streams, ditches and paddy fields. Due to serious river pollution, coupled with the massive application of pesticides and chemical fertilizers in paddy fields in successive years, it is difficult for leeches to reproduce and grow, and a large number of leeches die. Some producing areas have become extinct, thus reducing production by more than 30% every year.

2. The change of growth environment: in order to develop the local economy, the main leech producing areas have been exploiting mines, building roads, building factories, building houses, reclaiming wasteland and planting trees, and developing industrial parks and tourist areas in successive years. As a result, the environment on which leeches live has been seriously damaged, so that leeches have no place to live. At present, there are few groups of leeches in rivers and lakes in the main producing areas.

3. The price of leeches has risen year after year. One kilogram of dried leeches can be sold for several hundred yuan. The income from catching leeches greatly exceeds that of producing grain and vegetables. High profits stimulate the enthusiasm of the people in producing areas to catch leeches. Whenever there is a new period of production, they are caught indiscriminately and indiscriminately, and all leeches, big or small, are "fishing in the pool", affecting the reproduction of leeches.

4. the dosage has increased greatly: the elderly population in China has increased, the number of people suffering from cardiovascular and cerebrovascular diseases is increasing year by year, and the number of new drugs, specialty medicines and proprietary Chinese medicines produced with leeches as the main raw materials is increasing day by day. the raw materials for leeches have exceeded tens of times of those in the 1980s and 1990s.

5. Artificial breeding lags behind: artificial breeding has been carried out for 10 years, but there has been no breakthrough in technical difficulties, with slow growth and high mortality of leeches. Many producing areas have abandoned breeding one after another, and commercial leeches have not been put on the market.

Varieties of medicinal leeches

1. Wide-body golden leeches: wide-body golden leeches are the main breeding species in China at present, which mainly absorb the blood of animals, as well as plankton and mollusk larvae in the water, which are mainly characterized by large individuals, fast growth, high reproduction rate and easy fishing. It is the main species of breeding and promotion at present.

2. Sharp fine gold thread leech: sharp fine gold thread vermiculite alias tea leech, willow leaf leech, sharp fine gold line leech, there is a yellow longitudinal band on each side of the body, the ventral side is grayish yellow, and there is a band with dark brown spots on both sides. Feed on water earthworms and insect larvae, although the underdeveloped jaw can pierce the skin, but can not suck blood.

3. Japanese medical leeches: Japanese medical vermiculite bodies are long and narrow, slightly cylindrical, with slightly flat back and abdomen, mainly sucking human and animal blood, mainly fish and other animal blood in nature, not easy to raise in large areas, and are mostly used in vivo in medicine. There is no need to process drugs. There is a large demand for medical leeches abroad, but they must be live.

4. Light-moistened gold thread leech: the light-moistened gold thread vermiculite is slightly spindle-shaped, the front gradually becomes sharp and thin, and the mouth hole is in front of its trailing edge. The body is small, and its living habits are similar to those of wide-bodied golden leeches. It often feeds on snails (field snails, vertebral snails) and insect larvae, with small reproduction and low yield, so it is not suitable for artificial large-scale breeding.

5, stick pattern cow leech: the rod pattern cow leech body length is 100mm 160mm, the largest label is 225 mm, the maximum width of the body is 10mm 19mm, the diameter of the rear sucker is 1019mm, the living habits and contractual functions are similar to the wide body golden leech, and its size is large, the yield is high, and it is easy to raise, so the rod grain leech can also be cultured on a large scale as an excellent breed of artificial culture.
