The Possible Benefits of Prima U-a de Gato (TOA Free Cat's Claw)

A Dietary Supplement

Prima U-a-de Gato is free of tetra cyclic oxindole alkaloids (TOAs).

Prima U-a de Gato is a standardized whole herb, manufactured using a proprietary process that does not involve the use of solvents. Regular cat's claw contains both tetracyclic oxindole alkaloids and pentacyclic oxindole alkaloids, whereas Prima U-a de Gato is standardized to 0.5% pentacyclic oxindole alkaloids (POAs), and is 100% free of tetra cyclic oxindole alkaloids (TOAs). Why is this distinction important? Regular cat's claw typically has a total alkaloid content of 3.0%, with up to 20-25% of that alkaloid content in the form of TOAs. Prima U-a de Gato extract, standardized to a minimum of 0.5% POA, is free of TOA. The POA content of Prima U-a de Gato is much more effective, because immune enhancement is diminished when the two chemo types are mixed. TOAs are chemical antagonists that act upon the central nervous system and can greatly inhibit the positive effect of the POAs. POAs primarily affect the immune cells responsible for nonspecific and cellular immunity, and demonstrate powerful immune system modulating properties. In short, Prima U-a de Gato, containing only POAs, may have more benefit for immune enhancement than a standard cat's claw containing both penta cyclic and tetra cyclic alkaloids.

In addition, Prima U-a de Gato contains quinovic acid glycosides, the natural compounds upon which the synthetic antibiotic quinolones are based.

Prima U-a de Gato offers a significant advancement in our understanding of the best utilization of Uncaria tomentosa. The Prima U-a de Gato formula is potentized with minerals and enzymes to support detoxification, and has been clinically tested.
