冬虫夏草[Cordyceps sinensis(Berk.)Sacc.]是麦角菌科虫草属(Cordyceps)的一种药用真菌,主产于四川、青海、云南等省。为我国传统的名贵强壮滋补药,在国际市场上亦享有很高声誉。它有补肺益肾、止血化痰之功,常用于气短喘咳、自汗盗汗、阳萎遗精和腰膝酸痛、病后久虚不复等症。近年来,又报道具免疫功能,并用于抗肿瘤有一定功效。由于冬虫夏草生长环境特殊,分布在海拔3500～5000米的高山草甸之中,产量稀少,采集不易,价格昂贵。为了满足国内外日益增长的需要,我国医药工作者在寻求代用品、开发新资源等方面,做了大量研究和探索工
Cordyceps sinensis (Berk.) Sacc. is a medicinal fungus of Cordyceps, which is mainly produced in Sichuan, Qinghai and Yunnan provinces. For our country’s traditional noble and powerful tonic, it also enjoys a high reputation in the international market. It has the function of tonifying the kidney and strengthening the kidney, stopping bleeding and removing blood stasis. It is commonly used in shortness of breath, cough, spontaneous sweating, impotence, nocturnal emission, and pain in the waist and knees. In recent years, it has also been reported that it has immune function and has a certain effect for anti-tumor. Due to the special growth environment of Cordyceps sinensis, it is distributed among alpine meadows with an altitude of 3,500 to 5,000 meters. The yield is scarce, collection is difficult, and the price is expensive. In order to meet the growing needs at home and abroad, Chinese medical workers have done a lot of research and exploration in seeking substitutes and developing new resources.
