Qianzheng Patch

Qianzheng Patch is a topical transdermal patch based on traditional Chinese medicine principles, typically used for the adjunctive treatment of peripheral facial paralysis (such as Bell's palsy). The formulation is inspired by the classic TCM prescription "Qianzhengsan" (牵正散), which traditionally contains ingredients like giant typhonium rhizome (Bai Fu Zi), scorpion, and white mustard seed. The patch is applied to the skin over affected areas to deliver herbal actives locally. Its mechanism of action is not fully elucidated in Western pharmacological terms but is believed in TCM theory to dispel wind and resolve phlegm, thereby improving nerve function and reducing symptoms of facial paralysis. There are no robust clinical trials published in major English-language medical databases specifically for "Qianzheng Patch," but related studies on oral or decoction forms suggest potential benefit when combined with other therapies[10]. It should be noted that this product falls under complementary/alternative medicine rather than conventional pharmaceuticals.
