Yi Guan Acupuncture and Chinese Herbalism is proud to offer our own line of herbal medicinal teas designed to taste good and be good for you. Today we’d like to present Windbreaker, a tea with many uses around boosting immunity and regulating inflammation.


This tea is the classic preparation of the Chinese formula Yu Ping Feng San, which translates to Jade Wind Screen powder. The herbal actions include augmenting qi, stabilizes the exterior, and stopping sweating. In other words, it boosts the immune system, for active issues or preventatively. In Chinese medicine, wind refers to things that come and go, or carried into the the body from outside. In modern terms would include but is not limited to allergies and other upper respiratory tract infections. “Guarding against wind” is how the formula got its name. The chief herb is huang qi, also known as astragalus root, and has a high reputation in the modern West with adaptogenic, anti-oxidant, antiviral, anticoagulant, and hormone balancing properties. One of its deputy herbs, bai zhu, or atracylodes root, is also a known adaptogen, substances good for harmonizing the body in response to physical and emotional stress. The third herb in this blend is fang feng, or saposhnikovia root,has many compounds that exhibit significant anti-inflammatory, analgesic, antioxidant, antiproliferative, antitumor, and immunoregulatory activities.


Though in use for centuries, Chinese herbal formulas are relatively new to Western pharmacologic study. This particular formula, however, due to its prior fame and wide effective use, has already been the focus of many studies. Several randomized controlled studies and subsequent meta-analyses have been conducted that demonstrate the formula’s effectiveness for allergic rhinitis and allergic asthma symptoms. Other studies demonstrate the proposed mechanisms of action. One study showed that the formula reduces cytokine expression and thereby decreases inflammation in the airway in cases of allergic asthma. Another study demonstrated its use in atopic dermatitis by repairing tight junctions defects of epithelial cells. Other studies show that the formula increases glutathione transferase enzymes, which aside from allergy symptoms has even found use as a chemotherapy adjuvant.


Similar to use as elderberry juice this is a good adjunct for any kind of immunity boost or support, and beyond. If you’re prone to catch cold’s very often, known as external wind invasion in Chinese medical terms, then his is the tea for you. If year after year your allergies overwhelm you, this tea can help guard against symptoms, especially combined with our Northwest Passage tea for nasal decongestion. As per the classical preparation instructions, the astragulus root has been fried in honey before preparation into the tea and increases the tonifying properties of the herb. This makes for a sweet, nurturing tea, which is suitable for longer term use. As with all of our teas, it is sold as a finely ground powder, and not as loose tea leaves or coarsely ground leaves. This caffeine-free tea is not steeped in a tea bag and later removed, like jasmine tea. But it is dissolved in the water and ingested with the beverage, similar to matcha tea. Add 3 grams of the powder (or 1-2 teaspoons) to a cup of warm water and enjoy!
