Huang Bai Powder (Phellodendron amurense) — Ultra-Fine Sichuan Cortex Phellodendri, Sulfur-Free Herbal Powder

Huang Bai Powder (Phellodendron amurense) is the ultra-fine milled inner bark of a highly revered traditional herb known in Traditional Chinese Medicine (TCM) as Huáng Bǎi (黄柏), also called Amur Cork Tree Bark or Cortex Phellodendri. For centuries, Huang Bai has been prized as a bitter, cold, drying herb used to clear damp-heat, cool the lower burner, and drain fire from the body. Its nature is bitter and cold, making it a potent yet focused herb traditionally associated with the Kidney, Bladder, and Large Intestine channels. This ultra-fine powder is produced from authentic Sichuan-origin bark, naturally sun-dried and sulfur-free, intended for external application, foot soaks, and topical poultices, or for decoction under the guidance of a qualified TCM practitioner.

It is a classic ingredient in herbal foot soak blends and topical washes used in daily wellness routines.
