About the Chinese Medicinal Cockroach

Eupolyphaga sinensis (Chinese: 土鳖虫), is a species of cockroach in the genus Eupolyphaga. They are most abundant in Central and Northern China, but also extend into South Russia, and likely Mongolia. It is the most widely distributed species within the genus. E. sinensis are mainly scavengers which feed on plant debris.

It is well known for its use in traditional Chinese medicine. For commercial use they are bred and raised artificially, once mature they are collected, boiled in water, and dried either in the sun or by baking. Its common name in China, Tubiechong, is often used in reference to traditional Chinese medicine, it can also be used to generally mean a medicine which contains E. sinensis, along with other components. Tubiechong may also refer to several other cockroach species as medicine.

The species was originally described based on female morphology, being a member of Polyphaga, while the males were described as a separate species, Homœogamia sinensis. Further and re-examination resulted in Eupolyphaga sinensis being established. Historically males were confused with the species E. thibetana and E. yunnanensis, they are now recognized as separate species,... Wikipedia →
