Drug intelligence / Profile preview
Tongjingling Granules (痛经灵颗粒) is a Traditional Chinese Medicine (TCM) product developed and manufactured by Beijing ASIA-EAST Biopharmaceutical (Beijing Yadong Biopharmaceutical). It is an approved pharmaceutical in China, specifically indicated for the treatment of dysmenorrhea (painful menstruation) within the field of gynecology. The formulation is based on TCM principles of 'activating blood circulation to dissipate blood stasis' and 'regulating Qi to alleviate pain.' It typically contains a combination of herbal extracts such as Angelica sinensis, Corydalis yanhusuo, and Cyperus rotundus, which work synergistically to reduce uterine smooth muscle spasms and inhibit inflammatory mediators. The product is intended for patients whose dysmenorrhea is characterized by Qi stagnation and blood stasis, often presenting with abdominal pain and menstrual clots.
