Cassia—a term that can refer to several plants, most commonly Cinnamomum cassia (Chinese cinnamon) or Senna species—has a long history of use in traditional medicine, especially in Chinese and Ayurvedic systems. In traditional Chinese medicine (TCM), Cassia (Gui Zhi or Rou Gui) is sometimes incorporated into herbal blends intended to address headaches and related symptoms, which may overlap with what modern medicine classifies as migraine. However, the rationale is typically based on TCM concepts of balancing internal energies (Qi) or dispelling “wind” or “cold” rather than on neurological mechanisms. Direct references to Cassia being used solely or specifically for migraine are sparse; its inclusion in migraine remedies is usually as part of broader multi-herb formulas for general headache or circulatory issues.

There is very limited scientific evidence supporting Cassia’s use for migraine. Most modern research on Cassia focuses on its anti-inflammatory, antioxidant, or blood sugar-lowering properties, rather than headache relief. No clinical trials or robust studies have demonstrated efficacy for migraine treatment. Thus, its use for migraine is best characterized as traditional, with weak supporting evidence and no clear scientific validation.
