Can the "tomorrow" of leeches still be brilliant (part I)

Introduction

The bell of 2014 has already rung, let us familiar and unforgettable 2013 has become history, can not help but feel that time is fleeting, the ancients said: "the deceased, such as Shifu, day and night", but yesterday can not be retained, tomorrow can still be traced back. In 2013, the market of leeches rose all the way. The price of leeches in Bozhou market rose from 680 yuan in January to 830 yuan in December, an increase of 22.06%. The price of leeches (with a wide range of alum water) rose from 480 yuan in January to 570 yuan in December, an increase of 18.75%. So will the future of leeches continue to rise? Let's carefully analyze the "yesterday" and "today" of leeches, and move towards the "tomorrow" of leeches.

I. introduction of varieties

Leech: according to the 2010 edition of Chinese Pharmacopoeia, this product is the dry whole of leeches, leeches and willow leeches of the family hirudidae. The capture in summer and autumn is mainly around Ching Ming Festival, and from mid-August to September every year; burn to death with boiling water, dry or dry at a low temperature. Leech has the effect of breaking straight menstruation, removing blood stasis and eliminating leprosy, mainly for amenorrhea of blood stasis, addiction to ruffian mass, stroke hemiplegia, fall injury. Mainly produced in China's Shandong, Jiangsu, Anhui, Henan, Hebei and other places.

Second, the "yesterday" of leeches has changed from no one to hot.

Looking at the long history of leeches, it is not difficult to find that the market development of leeches is magnificent, from 7-8 yuan to 900 yuan, and gradually transformed from an unknown small role into a dazzling star on the medicinal stage, from unattended to hot.

(1) No one cares: from the late 1980s to the early 1990s, leeches can be seen everywhere. Due to the weak research and development efforts and less consumption, no one cares, and the price is silent between 7 and 8 yuan.

(2) Hot: since the early 1990s, after more than 20 years of development, the price of leeches has increased by leeches by leeches, showing four clear peaks from the historical table of leech prices, and it is these peaks that have pushed leeches to star status. The author makes a specific analysis of the four peaks below.

The first peak: the industrial development of leeches began in 1989, when Naoxuekang Oral liquid, a new drug developed with leeches as raw materials, became famous because of its good curative effect, so domestic pharmaceutical companies followed suit one after another, and the consumption of leeches increased greatly. finally in 1991, the price of leech reached its first peak of 150 yuan in March due to the contradiction between supply and demand. From then on, the leech jumped and began to enter everyone's line of sight. After the first peak, the price of leeches stabilized for the following reasons: since 1989, leeches were heavily fished, especially the high price in 1991, which stimulated farmers' enthusiasm for fishing, big or small, frenzied fishing. In 1991, the peak of production was between 100 and 120 tons, supply exceeded demand, and prices began to decline.

The second peak: after 1991, leeches were affected by price slippage on the one hand; on the other hand, in order to prevent the disease of blood-sucking insects in the flood in 1998, snails were used to kill snails on a large scale during the dry season in 1999. Field snails are not only the parasite of Schistosoma japonicum, but also the food of leeches. The production of leeches has plummeted. Under the pull of market demand, coupled with major speculation, the market finally broke out in 2000, and the price rose to the second peak of 210 yuan in July. Since then, the country set off a fishing boom, various lakes were turned upside down, production increased, coupled with the large families began to withdraw, prices gradually fell.

The third peak: here the author has to mention that leeches are hermaphroditic and heterogamorphic. Although the reproductive ability is extremely strong, generally only leeches that reach the age of three have the ability to reproduce, and they reproduce in the spring and autumn, which coincides with the fishing season. But the captors are eager for quick success and quick profit and excessive capture, which has a devastating impact on leech reproduction, and it is obvious that leech resources are reduced year by year. The contradiction between supply and demand was exposed in the city, and the price soared to the third peak of 280 yuan in June 2004. High prices stimulate fishing enthusiasm, rich supply, but also suppress part of the demand, some manufacturers choose not to use leeches, the demand is reduced, resulting in a decline in popularity, and then the price began to decline, it can be seen that the demand for leeches is not rigid.

The fourth peak: first, the wild resources of leeches began to dry up under the influence of overfishing and water pollution, and the domestic planting technology was ineffective; secondly, with the intensification of China's aging population, cardiovascular and cerebrovascular diseases, hyperlipidemia, thrombosis and other diseases have an increasing demand for leeches, which is also in short supply. the price of leeches began to rise in 2007 and reached the fourth peak of 865 yuan in June 2011. Since then, the price of new leeches began to decline, but soon began to pick up in July 2012, and the upward trend continues to this day.

Through the analysis of the historical development of leeches, the peaks and troughs go hand in hand, and each peak formation is the compensation for the low trough price. Some people say that leeches are like active volcanoes. I don't know when they will erupt. now that the price of leeches is strong, are they preparing for the next peak?

Third, whether the "tomorrow" of leeches is still brilliant.

The technology of growing leeches at home is fully mature, that is, before a large number of domestic resources are listed, it is an inevitable development trend that supply falls short of demand. Since July 2012, the market has continued to rise, so where is the next peak of leeches? Is the "tomorrow" of leeches still brilliant? In the next issue, the author will make an all-round analysis of the "today" of leeches, and let's walk into the "tomorrow" of leeches together.
