Cat’s Claw Quality
Cat’s Claw (Uncaria tomentosa) is an herb traditionally used by the Asháninka Indians of Peru. The tribe recognized two different types of this plant (one was used therapeutically, 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. The upper trace of herb, labeled A, shown below was rejected by our quality assurance testing as it contained the TOAs. The bottom trace of herb, labeled B, contains very low levels of TOA and was accepted.
