Uncaria tomentosa (a woody vine found in the Amazon rainforest) is popularly known as "Cat's Claw" because of its claw-shaped thorns.
What is Cat's Claw?
Cat's Claw (also known as vilcacora) derives its name from the Indian language of the Quechua people to mean a "sacred plant". Cat's claw has been used in traditional health practices and can be found in the forests of South America (mainly Peru and Brazil) and in Central America. Currently, Cat's Claw is used in Western countries as a nutritional supplement for a variety of health conditions. It is also used to support the immune system and as a support herb for viral health. HIV and herbes are believed to be viral infections. *
Nutritive Value and Bioactive Constituents
The chemical constituents of Cat’s Claw have been extensively studied since the early 1900s. More than 200 compounds have been isolated from Uncaria tomentosa, including alkaloids, triterpenes, ﬂavonoids, and phenylpropanoids.
123 indole alkaloids have been identiﬁed and are classiﬁed as monoterpene indole, monoterpene oxindole, and N-oxindole monoterpene indole alkaloids. Of these, oxindole alkaloids are regarded as major components (especially rhynchophylline and iso-rhynchophylline), as well as the corresponding unsaturated oxindole alkaloids like corynoxeine and isocorynoxeine. 82 triterpenoids have been isolated from this genus and quinovic acid is a common compound. 40 ﬂavonoids have been identiﬁed from the Uncaria tomentosa which are classiﬁed to be ﬂavan-3-ols and ﬂavonols.
