Details & Ingredients


We prepare our Corydalis yanhusuo extract from the traditionally processed tuber of Purity Verified plants. The tuber is harvested in the spring or fall, then carefully shade-dried and thoroughly extracted. The tuber is processed with rice vinegar after harvest according to traditional Chinese methods. Corydalis is then dried and thoroughly extracted.

The herb is extracted in small batches with Certified Organic cane alcohol to maintain the balance of phytochemicals as they exist in the plant. We assure herb identity via macroscopic and organoleptic analysis, then confirm it through methods such as HPTLC fingerprinting specific to each herb. Our liquid extracts are easily dispensed, taken in liquid form and added to water or other liquid.
