Bi Yan Pian 鼻炎片, literally "nasal inflammation tablets" in Chinese, is a Chinese herbal medicine particularly formulated for rhinitis. It is a commonly recommended herbal remedy by Chinese doctors to help relieve rhinitis and sinusitis symptoms such as nasal congestion, and stuffy nose with phlegm.

What does it do?
Rhinitis is an irritation and inflammation of the nose. Rhinitis is caused by airborne irritants, virus, or bacteria which trigger the release of histamine. Histamine opens the blood vessels, causes swollen membranes, and produce excessive fluids. Rhinitis is often associated with the common cold, or flu.

In Traditional Chinese Medicine (TCM), rhinitis is due to the insufficiency of Qi (Chi) energy of the lung and the subsequently weakened protection of the respiratory track from the foreign substances like bacteria and virus (toxins). Bi Yan Pian combines multiple Chinese herbs that act at several aspects to help relieve rhinitis. It disperses wind and expels toxins to relieve inflammation. Moreover, it dissolves phlegm (especially thick, yellow discharge), clears discharge and thus opens the nasal passages. Bi Yan Pian can be used for rhinitis, allergy, chronic rhinitis, and sinusitis.
