About This Formula

In Traditional Chinese Medicine, a layer of protective Qi called Wei Qi circulates at the surface of the body, much like a first line of immune defense. When Wei Qi is weak, the ‘screen’ is thin: a person catches colds easily, sweats without exertion, and feels worse in wind or drafts.

Yu Ping Feng San — the ‘Jade Windscreen’ — uses just three herbs to tonify Qi, secure the exterior, and gently dispel wind, reinforcing the body’s natural defenses. It is traditionally taken as a preventive support between illnesses rather than during an active cold. The most appropriate formula always depends on an individual’s TCM pattern, which the quick screening below helps confirm.
