Jiang Can Powder (Bombyx batryticatus) — Dried Silkworm Herbal Powder, External Use

Jiang Can Powder (Bombyx batryticatus) is the finely milled, naturally sun-dried body of the silkworm larva known in Traditional Chinese Medicine (TCM) as Jiāng Cán (僵蚕), also called White Stiff Silkworm (白僵蚕). For centuries it has been honored as a wind-calming, phlegm-transforming, and spirit-settling herb, traditionally used to ease spasms, tremors, numbness, and disorders of internal wind. Its nature is salty, pungent, and neutral, making it a steady yet focused herb for soothing the Liver, dispersing stagnation, and harmonizing the channels. This powder is offered as a raw agricultural herb material intended for external application, foot soaks, and topical compress use, or for decoction under the guidance of a qualified TCM practitioner.
