What is Yu Ping Feng San?

Yu Ping Feng San, also known as Jade Windscreen, is a popular formula during cold and flu season. The formula contains just three herbs: Huang Qi, Bai Zhu, and Fang Feng.

What are the benefits of Yu Ping Feng San?

The primary benefit of Yu Ping Feng San is to support the immune system. 

Rather than managing specific cold and flu symptoms such as cough, fever, and chills, Yu Ping Feng San helps individuals build and maintain immunity by providing systemic support.

TCM practitioners often prescribe Yu Ping Feng San for individuals with spontaneous sweating with aversion to cold, along with fatigue and a floating, weak pulse.

What is the dosage and method for taking Yu Ping Feng San?

The generally recommended dosage of Yu Ping Feng San in capsule form is four capsules, two to three times daily; or as loose granules, 4.5 g mixed with hot water, 2-3 times per day. However, always follow your healthcare provider's instructions, as the dosage can vary based on your condition and response to treatment.

Please see What's the Recommended Dosage for Granule Herbs? for more information.

When can I expect to see results?

Yu Ping Feng San typically starts to take effect within days. However, like all treatments, its efficacy can vary from person to person.

Does Yu Ping Feng San have any side effects?

While Yu Ping Feng San is generally considered safe for most people, it can cause side effects in some individuals. Women who are pregnant, nursing, or postpartum as well as people with liver disease, should avoid or use Yu Ping Feng San with caution.

As with any Chinese herb, we recommend consulting with a qualified practitioner of traditional Chinese medicine (TCM) about Yu Ping Feng San before any course of treatment is started.
