The first documented use of Cordyceps in traditional Chinese medicine can be traced back to the "Ben Cao Bei Yao," which is a text written during the 15th century. This text is often referred to as the "Compendium of Essential Materia Medica," and it was authored by Chen Shiduo, a Chinese pharmacologist and physician during the Ming Dynasty.

It details various medicinal substances, their properties, and their uses in the context of traditional Chinese medicine. Cordyceps, known as "Dōng Chóng Xià Cǎo" in Chinese, is included in this compendium, marking one of the earliest recorded mentions of Cordyceps in a written document. It is noted for its believed ability to boost vitality, improve lung function, and enhance endurance.

Cordyceps were considered rare and precious historically due to their limited availability and unique growth process. They were often reserved for emperors and the elite, and their high market value earned them the nickname "Caterpillar fungus."

While Cordyceps have been a staple in traditional medicine, modern scientific research today studies them for their potential use in various applications, such as improving athletic performance, enhancing the immune system, and potentially treating certain health conditions.
