Corydalis Yanhusuo Tuber Extract
Also known as: Yanhusuo, Xuanhu, Corydalis yanhusuo
Overview
*Corydalis yanhusuo* is a perennial herb native to China, Japan, Korea, and Russia. The medicinal part used is the tuberous rhizome. It contains over 160 identified compounds, predominantly alkaloids such as corydaline and tetrahydropalmatine (THP). Traditionally, it's used for analgesic, anti-inflammatory, and sedative purposes, often to treat pain, improve circulation, and alleviate conditions like dysmenorrhea. Current research is advancing but primarily consists of preclinical studies, with a lack of comprehensive systematic reviews. The existing evidence suggests promising pharmacological effects, particularly in pain management and opioid tolerance prevention, though further rigorous human trials are necessary to clarify its efficacy and safety.
Benefits
Key benefits of *Corydalis yanhusuo* include its analgesic effects, supported by animal studies indicating its ability to block certain brain receptors, thus providing sedation and pain relief. It also shows potential in preventing morphine tolerance and dependence, making it beneficial for individuals at risk of opioid addiction. Secondary effects include anti-inflammatory properties, inhibiting mast cell activation, and possible cardiovascular benefits. Populations suffering from chronic pain and those dealing with food allergies may find particular relief. While preclinical evidence demonstrates significant effectiveness, human clinical data are needed to substantiate these claims further.
How it works
The extract works through several biological pathways, including the inhibition of cyclin-dependent kinase 2 (CDK2) and activation of the PLC/PKC/STAT3 signaling pathway for anti-allergic effects. It primarily exerts analgesic and sedative impacts by blocking dopamine receptors in the central nervous system. By affecting these pathways, *Corydalis yanhusuo* facilitates pain relief and may enhance blood circulation, potentially benefiting cardiovascular health as well.
Side effects
The overall safety of *Corydalis yanhusuo* is considered positive based on traditional use and animal studies, though comprehensive human safety data are lacking. Common side effects are not well-documented, and there are no notable uncommon or rare side effects reported. Potential drug interactions include opioids and central nervous system depressants due to its sedative properties. Caution is advised for individuals with a history of substance abuse or those on CNS depressants. Pregnant and breastfeeding women should use the extract with caution, given the absence of extensive safety assessments.
Dosage
Currently, the minimum effective dose of *Corydalis yanhusuo* has not been established in human studies. Optimal dosage ranges remain undefined, as preclinical models suggest varying doses may yield efficacy. There is no established maximum safe dose for human intake, nor are specific timing and administration guidelines laid out in the literature. The extract is commonly available in various forms, though the most effective administration route remains unstudied. Absorption factors have yet to be thoroughly investigated, but preclinical data imply adequate bioavailability.
