Although the formula disperses pathogenic Wind-Dampness, it is unsuitable for treating Excess patterns. It is because it focuses on preventing pathogenic Qi from entering the body, not on dispersing pathogenic Qi from the body. Therefore, unless significantly modified, it is not suited for releasing pathogenic Qi from the Exterior in Excess patterns even where such Excess occurs against a background of Qi Deficiency. see more

Yu Ping Feng San is a 3-ingredient Chinese Medicine formula with Milkvetch Roots (Huang Qi) as a principal ingredient.
Invented in 1213 AD, it belongs to the category of formulas that tonify Qi. Its main actions are: 1) augments the Qi and 2) stabilizes the Exterior.
In Chinese Medicine health conditions are thought to arise due to "disharmonies" in the body as a system. These disharmonies are called "patterns" and the very purpose of herbal formulas is to fight them in order to restore the body's harmony.
From a Western Medicine standpoint, such patterns can give rise to a range of conditions such as recurrent upper respiratory tract infections, glomerulonephritis or allergic rhinitis for instance.
On this page, after a detailed description of each of the three ingredients in Yu Ping Feng San, we review the patterns and conditions that Yu Ping Feng San helps treat.
The three ingredients in Yu Ping Feng San
Huang Qi is a king ingredient in Yu Ping Feng San. Like the name indicates, it means it has more power than other ingredients in the formula.
1. Milkvetch Roots (Huang Qi)
Huang Qi is an extremely powerful in strengthening the Qi and stabilizing the Exterior. It tonifies the superficial or Exterior aspects of the Lungs and Spleen. It enters the Lungs to tonify the Qi, and enters the Exterior to firm up the Protective Qi. It is one of the most important Qi tonifying herbs.
Bai Zhu is a deputy ingredient in Yu Ping Feng San. This means it helps the king ingredient(s) treat the main pattern or it serves to treat a coexisting pattern.
2. Atractylodes Rhizomes (Bai Zhu)
Part used: Dried rhizome
Nature: Warm
Meridian affinity: SpleenStomach
Category: Tonic herbs for Qi Deficiency
Bai Zhu strengthens the Spleen and augments the Qi. It reinforces the actions of the key herb and strengthens the metal Lungs by cultivating the earth Spleen. The combination of the key and deputy herbs generate Qi by tonifying the Spleen, which is the source of Qi and Blood. It also stops sweating. The Exterior is thereby stabilized, and sweat will no longer leak from the interstices and pores. This also prevents pathogenic influences from easily penetrating the outer defenses of the body.
Fang Feng is an assistant ingredient in Yu Ping Feng San. This means that it either serves to reinforces the effect of other ingredients or it moderates their toxicity.
3. Saposhnikovia Roots (Fang Feng)
Fang Feng disperses Wind while tonifying at the same time. It circulates in the Exterior of the body where it expels Wind without damaging the Body Fluids, therefore the Lungs is not injured. In concert with key herb, it stabilizes Exterior without causing the pathogenic influences to linger, and expels pathogenic influences without harming the normal Qi.
