Dried Cockroach (Eupolyphaga sinensis) — Traditional Chinese Medicinal Insect, 500g

Dried Cockroach (Eupolyphaga sinensis), known in Traditional Chinese Medicine (TCM) as Zhāng Láng (蟑螂) and historically referred to as Tǔ Biē Chóng (土鳖虫) in related medicinal insect traditions, is the dried whole body of a long-recognized medicinal insect used in Chinese herbal practice. For centuries, this cold-natured insect has been prized as a blood-quickening, stasis-dispelling, and collateral-unblocking herb, traditionally used to relieve fixed abdominal pain, support bone and tendon recovery, and promote smooth circulation. Its nature is salty and cold, making it a focused yet traditional herb for moving blood and resolving stagnation.
