Primary Actions

Dispels wind-damp and strongly stops pain - Cao Wu is used for severe cold-damp painful obstruction with fixed, intense, penetrating pain in the joints, tendons, and bones.
Warms the channels and scatters cold - traditional indications include cold abdominal pain, cold hernia pain, and deeply lodged painful conditions that improve with heat.
Reduces swelling and treats traumatic pain - external or carefully supervised internal use extends to injury, numb painful limbs, and hard cold-type swellings.

Cao Wu with Chuan Wu - classic severe cold-pain pairing for stubborn wind-cold-damp painful obstruction.
External Cao Wu wines, plasters, or wash formulas - traditional trauma and severe arthralgia approaches in which the herb's analgesic power is used while limiting systemic exposure.
Processed into Zhi Cao Wu for later pill and formula traditions - a crucial clinical pathway that reduces toxicity before broader internal use.

Traditional references describe Cao Wu as acrid, bitter, hot, and toxic, entering the Heart, Liver, Kidney, and Spleen to dispel wind-damp, warm the channels, and alleviate pain.
Classical incompatibility cautions remain with Ban Xia, Gua Lou, Tian Hua Fen, Bai Ji, Bai Lian, and the Bei Mu species.
This page intentionally preserves raw Cao Wu as a separate high-risk medicinal identity rather than flattening it into safer processed aconite records.
