Herb Pharm harvests the inner bark of Uncaria tomentosa vines responsibly wildcrafted by indigenous peoples of the Peruvian Amazon, then sun-dries, and meticulously cleans it before thoroughly extracting for Cat's Claw extract.

The herb is extracted in small batches with Certified Organic cane alcohol for potency and to maintain the balance of phytochemicals as they exist in the plant. Herb Pharm assures herb identity via macroscopic and organoleptic analysis, then confirms it through methods such as HPTLC fingerprinting specific to each herb. The formula is easily dispensed, taken in liquid form and added to water or other liquid.
