Hei Chou Powder (Pharbitis nil) — Dried Botanical Powder for External Use & Foot Soaks

Hei Chou Powder (Pharbitis nil) is the finely milled seed powder of a traditional herb known in Traditional Chinese Medicine (TCM) as Hēi Chǒu (黑丑), also called Qiān Niú Zǐ (牵牛子). In TCM it is classified as a purgative and water-expelling herb with a bitter, cold nature and toxicity in its raw seed form, which is why it is traditionally reserved for external application, foot soaks, and professional herbalist-guided decoctions rather than casual daily consumption. This listing is a naturally sun-dried, small-batch powder intended for topical and external wellness use.

Traditional Uses

In folk herbal practice, Hei Chou (Qian Niu Zi) has long been recorded among the purgative and water-expelling herbs, traditionally used in decoctions guided by a professional TCM practitioner. Because of its strong, cold, and toxic character, it is rarely taken casually; instead, it appears in external preparations such as herbal pastes, compresses, and foot-soak blends, where it is combined with warming or soothing herbs. In daily external wellness routines, it is mixed with warm water or herbal liquids and applied to the skin or soaked at the feet, following traditional topical practice rather than internal consumption.
