Customer questions / expert answers
The short answer is yes; the herb is sourced from the Amazon region of South America.
The long answer, as per the MediHerb catalogue - Cat's Claw is a herb traditionally used by the Asháninka Indians of Peru. The tribe recognised two different types of this plant (one was used therapeutically and the other was never used). This difference has been verified phytochemically and two chemotypes have been identified: the preferred chemotype contains only pentacyclic oxindole alkaloids (POAs) speciophylline, mitraphylline, pteropodine, isomitraphylline and isopteropodine; the other chemotype, which was never used, contains the tetracyclic oxindole alkaloids (TOAs) rhynchophylline and isorhynchophylline in addition to the POAs. The preference for the POA chemotype of Cat's Claw has been validated by scientific research. MediHerb tests each batch of Cat's Claw to determine that only the preferred chemotype is used to manufacture our Cat's Claw products.
