Bai Chou Powder (Pharbitis nil) — Fine-Milled White Morning Glory Seed, External-Use Botanical Powder

Bai Chou Powder (Pharbitis nil) is the finely milled seed powder of White Morning Glory, known in Traditional Chinese Medicine (TCM) as Bái Chǒu (白丑), the pale-seeded form of Qiān Niú Zǐ (牵牛子). In TCM it is classified among the purgative and water-expelling herbs, with a nature that is bitter, cold, and strongly descending, entering the Lung, Kidney, and Large Intestine channels. Because it is not a food-herb (药食同源) ingredient, this powder is offered strictly as a raw botanical material for external application, foot soaks, and professional formulation — not for casual daily ingestion.

Quality & Sensory

Each batch is sun-dried naturally and milled to a fine, uniform powder that ranges from pale grey-brown to a soft ivory tone, depending on the seed batch. The texture is smooth and free-flowing with a faint, dry, nutty-seed aroma and a subtle earthy note. When moistened for external pastes or foot-soak blends, it forms a soft, workable consistency without heavy grit, and carries a mild, slightly bitter botanical scent rather than a sharp or acrid one.

Traditional Uses

In classical TCM literature, Bai Chou is grouped with the purgative and water-expelling herbs and is traditionally described as bitter, cold, and descending, entering the Lung, Kidney, and Large Intestine channels. It has long been used in compound decoctions formulated by professional practitioners to move stagnant water and open the bowels, and it appears in old formulas alongside herbs such as Gan Sui and Da Ji. In folk external practice, the milled seed is blended into pastes and poultices applied to the skin, or added to warm foot-soak water, rather than taken as a daily tea or food. Because it is not a food-herb ingredient, traditional use is confined to practitioner-guided decoction and external application.
