Samento is the trade mark for a very special variety of the Peruvian herb Cat`s Claw (Uncaria tomentosa). Cat’s Claw is a climbing vine that is native to the Amazon rainforest and has been used for over two thousands years by rainforest tribes to contribute to the immune system.
The Asháninka people, who have the longest recorded history of use of the herb, make a clear distinction between certain Uncaria tomentosa vines - and now it has been revealed that there are indeed differences.
It has been shown that the action of one of the main group of actives in Cat`s Claw bark - the Pentacyclic Oxindole Alkaloids (POAs), can be adversely affected by the presence of a further group - the Tetracyclic Oxindole Alkaloids (TOAs). However, certain plants are naturally free from this second group of alkaloids and Samento is only made with TOA-Free plants.
