Yan Hu Suo (Corydalis) Vinegar-Cured Granules 10:1 | ActiveHerb 100g
If you’re buying Yan Hu Suo (Corydalis yanhusuo), you’re probably not looking for herb trivia—you want to know what form this is, how strong it is, and how to use it correctly. These are vinegar-cured (Cu Zhi) 10:1 concentrated granules designed for fast prep: simply dissolve in hot water and drink. Vinegar processing is a traditional preparation method, and modern research shows processing can change Corydalis’ alkaloid profile—one reason practitioners often specify the processed form. Use as directed by a qualified practitioner.
This page gives clear answers—plus research links and safety notes.
Quick Summary On Yan Hu Suo
-
Herb: Yan Hu Suo (延胡索) — Corydalis yanhusuo tuber/rhizome
-
Form: Vinegar-processed (“Cu Zhi”) concentrated extract granules
-
Concentration Ratio: 10xActive Ingredients: Tetrahydropalmatine ≥ 1 mg/gOther Ingredients: Dextrin
-
Traditional TCM properties: Acrid, bitter, warm; classically described in patterns involving Qi/Blood stagnation (traditional language)
1) What is Yan Hu Suo?
Yan Hu Suo is a traditional Chinese herb made from the tuber of Corydalis yanhusuo. Modern reviews describe it as rich in alkaloids (including tetrahydropalmatine-family compounds) that are the main focus of pharmacology research.
Traditional summary (TCM language):
-
Moves Qi and Blood
-
Supports temporary relief of discomfort associated with stagnation patterns
(Traditional-use description; not a disease claim.)
2) What does “vinegar-cured” mean (and why it matters)?
“Vinegar-cured” is commonly referring to vinegar processing (Cu Zhi)—a traditional preparation method used for Yan Hu Suo.
Why shoppers should care: processing changes the alkaloid profile. A PubMed Central paper specifically examining vinegar/wine processing of Corydalis yanhusuo reports that vinegar processing can influence alkaloid content and discusses why vinegar-processed product has been favored traditionally.
A broader review on Corydalis processing also discusses vinegar as an auxiliary material used in processing and summarizes pharmacology/safety considerations across different processing methods.
Bottom line: “Vinegar-cured” isn’t a marketing adjective—it’s an identifiable processed form with a long history in TCM and measurable chemical differences.
3) What “10:1 / 10x” means in plain English
100 g extract granules are equivalent to 1000 g (2.2 lb) dried raw herb.
4) How to Use Yan Hu Suo Concentrated Granules

Stop use and seek medical advice if you have unusual symptoms.
6) Research
DHCB and pain signaling (preclinical)
A widely cited 2014 paper isolated dehydrocorybulbine (DHCB) from Corydalis yanhusuo and explored its analgesic activity and dopamine receptor involvement in animal models.
Processing matters (vinegar vs wine)
A PubMed Central study examined how vinegar/wine processing influences Corydalis alkaloids and discusses why vinegar-processed product is traditionally favored.
Comprehensive review
A modern review summarizes Corydalis’ constituents and pharmacology and notes that alkaloids are the major bioactive class studied.
Trust note: Much of the strongest mechanism evidence is preclinical. Real-world outcomes depend on the person, preparation, and practitioner guidance.
