Key TCM Concepts

Thsi is classic Yu Ping Feng San enhanced for epidemic prevention. The base formula (Huang Qi, Bai Zhu, Fang Feng) builds Defensive Qi. The additions address the specific characteristics of epidemic pathogens.

Jin Yin Hua and Guan Zhong clear Toxic-Heat; Pei Lan and Chen Pi transform Dampness.

It was developed by Hubei Province during COVID-19 as a preventive formula for healthcare workers exposed to "Damp-Heat plague". 

Use this strenghtened version during active exposure risk or outbreaks (weeks, not months). For long-term immune support, switch to the standard Yu Ping Feng San, which contains only the three core herbs and is appropriate for extended constitutional tonification.

This fomrula is not a treatment solution—this is prophylactic. It strengthens resistance before infection occurs, not after. Once actively sick with fever, sore throat, or respiratory symptoms, switch to formulas that release the Exterior and clear pathogens (eg: Yin Qiao San, Gan Mao Ling, etc.).

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.

Safety & Contraindications

Important safety information and precautions for Qiáng Lì Yu Ping Feng San

This information is for educational purposes only. Always consult with a qualified healthcare provider before using any TCM herbal formula.

Contraindications

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.

Herb-Drug Interactions

Like many TCM formulas, Qiáng Lì Yu Ping Feng San may interact with certain medications. If you are taking any prescription medications, we recommend consulting with a healthcare provider knowledgeable in herb-drug interactions.
