提起蚂蟥,许多人会不寒而栗,软塌塌的身子扭来扭去,一旦叮上人,不吸饱血绝不松口。一般人对它避之犹恐不及。可是江苏省宜兴市杨巷镇的张国英偏偏和蚂蟥较上了劲。一次,张国英从网上看到一则信息:蚂蟥(学名水蛭)是一种天然名贵药材,尤其对于防治心脑血管疾病和癌症等病症疗效极佳。近年来,随着需求量猛增,蚂蟥的身价不断提高,可是由于环境恶化和过度捕捞,野生蚂蟥越来越少,在市场上成了奇货可居的紧俏货,每年市场缺口高达300吨。 Lifting the leech, many people will shudder, and the body will be twisted and twisted. Once you come in, you will not be able to breathe blood and never let go. Most people can’t avoid it. However, Zhang Guoying, Yang Xiangzhen, Yixing City, Jiangsu Province, chose to compete with the grasshopper. Once, Zhang Guoying saw a message from the Internet: Leech (scientific name Shuizhe) is a natural valuable medicine, especially for the prevention and treatment of cardiovascular and cerebrovascular diseases and cancer and other diseases with excellent efficacy. In recent years, as the demand soared, the value of the leech has continued to increase. However, due to the deterioration of the environment and overfishing, wild leech has become less and less, and it has become a scarce commodity in the market. The annual market gap is as high as 300 tons.
