1, Rhizoma corydalis for relieving pain
A joint study published on 1 3rd by researchers from Dalian Institute of Chemical Physics, Chinese Academy of Sciences and University of California, Irvine, shows that Rhizoma Corydalis has a good effect on chronic pain, and it is not easy to be dependent.
As early as 1000 years ago, the efficacy of Yuanhu was recorded in Kaibao Materia Medica in the Song Dynasty. It is also known as Corydalis yanhusuo and Xuanhu, which can promote blood circulation, remove blood stasis, promote qi circulation and relieve pain, and can be used for the pain of qi stagnation and blood stasis, such as dysmenorrhea and traumatic injury.
The pain relief of traditional Chinese medicine is aimed at the causes of blood stasis and other reasons that cause pain, while western medicine reduces pain by acting on the nervous system. Traditional Chinese medicine emphasizes syndrome differentiation, and not all pains can be treated with Yuanhu. For example, Yuanhu Zhitong Tablet, a traditional Chinese medicine, is mainly used for dysmenorrhea with qi stagnation and blood stasis in clinic, but it is not necessarily effective for dysmenorrhea with deficiency syndrome (thin menstruation or light color with dizziness). And Yuanhu's pain relief is a temporary solution. If you want to treat both the symptoms and the root causes, you should also pay attention to the usual conditioning.
Clinically, it is indeed found that Rhizoma Corydalis is less dependent while relieving pain, but it should not be used indiscriminately. If you have symptoms such as rash and chest tightness after taking the medicine, you should see a doctor in time. Chronic pain should be treated in combination with its etiology.
