Relieve Chronic Pain Naturally with Corydalis Yanhusuo
What is corydalis yanhusuo?
The herb corydalis is native to Zhejiang, a province in China, and is a common remedy in traditional Chinese medicine. The tuberous rhizome has been valued for hundreds of years as a pain killer and is frequently used to manage a variety of acute and chronic pain conditions ranging from menstrual to abdominal and chest pain, among others.
Scientists have isolated and identified 20 alkaloids in the herb, including corydaline, tetrahydropalmatine (THP), and dl-tetrahydropalmatine (dl-THP), to name a few. THP is considered to be the most potent and has been shown to have an impact on the central nervous system, offering both sedative and pain-killing effects.
Corydalis yanhusuo and chronic pain relief
In recent years, scientists have been investigating the pain relieving abilities of this herb in both animal and human studies. The latest such effort comes from a team at the University of California, Irvine, where Olivier Civelli, professor and chair of pharmacology and his colleagues explored how the herb impacts chronic pain.
This latest study involved evaluating the effect of corydalis yanhusuo on acute, persistent inflammatory, and chronic neuropathic pain in mouse models, as well as lab testing to identify how the herb works.
Here’s what the researchers discovered:
- Corydalis yanhusuo, unlike morphine, does not result in the development of tolerance after taking the remedy daily for seven consecutive days. Tolerance is a major downside of narcotic painkillers.
- The herb appears to work as a potent dopamine receptor blocker. Research has shown that dopamine seems to have a role in sustaining chronic pain, thus blocking the receptors can reduce this type of pain.
- Corydalis yanhusuo “is not a highly potent medicine when compared to morphine, but I [Civelli] would propose that it can be used for low to moderate chronic pain.”
Other research on corydalis yanhusuo and chronic pain
The authors of another recent animal study reported that L-tetrahydropalmatine reduced both chronic inflammatory and neuropathic pain in mice. This study also showed the involvement of dopamine receptors.
An earlier study involved a rat model of trigeminal neuropathic pain. The authors found convincing evidence that dl-THP “may offer a useful therapeutic approach for trigeminal neuropathic pain.”
