Dispel Wind-Damp (qu feng shi)

Herbs such as du huo (Angelica pubescens) exert anti-inflammatory and analgesic effects that treat ‘bi zheng’ – acute or chronic pain (e.g. arthritis, sciatica), typically in the joints, tendons and muscles, caused by impaired flow of qi and blood due to internal (e.g. weak constitution, low immunity) and external (wind, damp or cold) factors.
