Jiang Can Powder (Bombyx batryticatus) — Dried Silkworm Powder, External & Foot Soak Use

Jiang Can Powder (Bombyx batryticatus) is the finely milled, sun-dried body of the silkworm larva traditionally known in Traditional Chinese Medicine (TCM) as Jiāng Cán (僵蚕), also called White Stiff Silkworm (白僵蚕). Long prized as a wind-calming, phlegm-transforming herb, Jiang Can has been used in classical formulas for soothing internal wind, easing spasms, and clearing the head. Its nature is salty, pungent, and neutral, entering the Liver and Lung channels. This batch is a freshly ground, ultra-fine powder intended for external application, foot soaks, and topical compress use, or for decoction under the guidance of a qualified TCM practitioner.

Quality & Sensory

Each batch is naturally sun-dried and then milled into an ultra-fine, pale greyish-beige powder with a soft, dry, free-flowing texture. It carries a faint, earthy, slightly protein-like aroma characteristic of dried silkworm. When decocted under practitioner guidance, it yields a mild, subtly salty infusion; as a topical or foot soak powder, it disperses easily in warm water without heavy residue.

Traditional Uses

In folk herbal practice, Jiang Can is decocted in classical formulas alongside herbs such as cicada slough, scorpion, and gastrodia to calm internal wind and ease spasms. It also appears in external preparations, where the powder is mixed with warm water, vinegar, or wine and applied as a poultice, and in foot soak blends for warming and soothing the lower body. In daily wellness routines, it is most often used externally rather than as a casual tea, reflecting its traditional role as a targeted herbal ingredient rather than a food-herb.
