Yuanhu, also known as Corydalis yanhusuo and Corydalis yanhusuo, is a perennial herb of Corydalis in Papaveraceae, and it is also called "Zhejiang Eight Flavors" with Atractylodes macrocephala, Paeonia lactiflora and Fritillaria, which is a common Chinese medicine. The history of Yuanhu is recorded in Kaibao Materia Medica. It is warm in nature, bitter in taste, and enters the heart, spleen, liver and lungs. It is a wonderful product for promoting blood circulation, removing blood stasis, promoting qi circulation and relieving pain, especially for its analgesic effect. In Compendium of Materia Medica, Li Shizhen concluded that Yuanhu has four functions: promoting blood circulation, regulating qi, relieving pain, and promoting urination, and praised Yuanhu's "stagnation of qi in blood and stagnation of blood in qi, so he specializes in treating all kinds of pains in the whole body".
