In what season can Cordyceps be mined?

Cordyceps sinensis can be dug in early summer. Every early summer, when the spores of Cordyceps sinensis are unearthed, they are dug out and dried to 60% to 70%, and fiber attachments and impurities are removed, and dried in the sun or at low temperature.

Cordyceps sinensis is only one of more than 90 kinds of Cordyceps sinensis in China, mainly produced in the Qinghai-Tibet Plateau, also referred to as "Cordyceps sinensis". Cordyceps sinensis is a kind of ergot fungus, which is parasitic on the larvae of Batmoths and is a complex of the larvae.

2016 On February 4th, the State Administration of Pharmaceutical Products announced that the arsenic content in Cordyceps powder and pure powder tablets was 4.4 ~ 9.9 mg/kg. Long-term consumption of Cordyceps powder and pure powder tablets will lead to excessive arsenic intake and may accumulate in the human body, which has a high risk.

1On October 20th, the former US Food and Drug Administration issued a notice to stop using Cordyceps sinensis as health food.

Crazy excavation of Cordyceps sinensis leads to ecological deterioration;

In order to protect the fragile ecological environment in the Three Rivers source area, in 2003, about 6,543,800 square kilometers of Yushu and Guoluo in Qinghai Province were established as national nature reserves, and Qinghai Province also promulgated relevant management measures to restrict and prohibit the harvesting of Cordyceps sinensis. However, due to the soaring price of Cordyceps sinensis, from the end of April to June every year, Guoluo and Yushu, which are rich in Cordyceps sinensis, still cannot stop a large number of collectors.

A large number of crazy and disorderly diggers not only seriously affected the local grassland ecological environment, but also brought great pressure to the grassland management of the local government, mainly in two aspects. First of all, there is no backfill after excavation. Digging a Cordyceps sinensis will destroy at least 30 square centimeters of turf.

The second is to use shrubs as fuel. During the excavation of Cordyceps sinensis, diggers had to set up tents in the mountains, make a fire and cook with local shrubs as fuel. The parasitic fungus, bat moth, relies on these bushes to survive, which destroys their living environment and makes Cordyceps sinensis in Qinghai more and more scarce.
