Corydalis Tuber is one of the most commonly used and most effective herbal pain remedies in TCM for pain relief as a result of Blood stagnation. When compared to morphine, Yan Hu Suo has shown a slower onset and weaker analgesic effect when given by injection. Evaluation of the analgesic effect based on weight showed Corydalis root  to be approximately 100:1 in effect by comparison to morphine, but Yan Hu Suo has not been associated with any dependency or addiction. Furthermore, development of tolerance happens approximately 100% faster with morphine than with Corydalis root.

Yan Hu Suo acts to activate Qi and Blood circulation to relieve pain, as an analgesic, sedative, anti-inflammatory, decreases resistance of blood flow and increases blood perfusion; decreases oxygen consumption of the cardiac muscle and increases contractility of the heart.
