Cat’s Claw NEO

(45 capsules Uncaria tomentosa (Willd) DC. C.N.: 159166.1)


Cat’s Claw is a vine of the Rubiaceae family. It is a native plant from Peru and owes its name to the particular shape of the spines found in the base of its leaves. The active part of this herb is its bark, which contains oxindole alkaloids (dihydrocorynantheine, isorhyncophylline, pteropodine, mitraphylline, rhynchophylline, speciophylline, hirsuteine, isomitraphylline, N-oxide-isomitraphylline, dihydrocorynantheine -N-oxide, N-oxide- hirsuteine, yohimbine and uncarine F); indole alkaloids, quinovic heterosids, triterpenes, steroids, polyphenols and proanthocyanidins.


Traditionally, Cat’s Claw has been used for its:

  • Immunostimulant and anti-inflammatory properties: the latter action is due to its ability to inhibit TNF alpha and, to a lesser extent, PGE2 prostaglandins production.
  • Inhibitory activity on cyclooxygenase 1 and 2. Its immunostimulant action is based on the regulation of lymphocytes proliferation (thereby exerting antiviral action and stimulating phagocytosis).
  • Beneficial effect on deteriorated memory: thanks to the effect of its alkaloids (mainly the oxindole).
  • Stimulation of DNA repair, the mitogenic response and leukocyte recovery after chemotherapy.
