What does it do
From the perspective of traditional Chinese medicine (TCM), obstruction of Qi flow or blood circulation causes body discomfort in the affected area. Qi is a vital energy circulating in the channels around our body. Many Chinese herbs are well known in TCM to move Qi energy and invigorate the Blood and may potentially relieve discomfort. Yan Hu Suo (Corydalis Rhizome) is one of such Chinese herbs. Yan Hu Suo Zhi Tong Pian (Corydalis Relaxe™) is a Guang Ci Tang® signature formula that includes Corydalis as the main ingredient and several other Chinese herbs that reinforce the action of Corydalis.
Yan Hu Suo in TCM acts to invigorate the Blood, smooth the Qi flow, and alleviate discomfort. Chinese herbalists have found that Yan Hu Suo is applicable in a wide range of conditions and is potent compared to other Chinese herbs. Yan Hu Suo also has a good safety profile in its action. It does not induce tolerance and physical dependence.
In addition to Yan Hu Suo, Corydalis Relaxe™ includes 3 other Chinese herbs, Bai Zhi (Dahurian Angelica Root), Xiang Fu (Cyperus Rhizome), and Chuan Xiong (Sichuan Lovage Rhizome) to further enhance the action of Yan Hu Suo. Here, Bai Zhi disperses Wind and alleviates discomfort in the head region. Xiang Fu promotes Qi movement, relieves Qi stagnation, and alleviates discomfort. Chuan Xiong is another famous Chinese herb that invigorates the Blood, smoothes Qi flow, and relieves discomfort. It also expels Wind.
Does research support Corydalis Relaxe?
Scientists have worked hard to reveal how Yan Hu Suo works in modern biomedical terms. A latest research that is published in 2014 and widely reported by media including Dr Oz show nicely illustrates such an effort. In the study1, scientists from China and America are able to pinpoint a single compound called DHCB (dehydrocorybulbine) from Corydalis to act the same way as Corydalis.
