General Description

RelaxMedix is a combination of two extracts: Samento, produced from Uncaria tomentosa, and Amantilla, produced from Valeriana officinalis, commonly known as Valerian; both perennial plants from South America.  Samento is made from the Uncaria tomentosa chemotype that does not contain Tetracyclic Oxindole Alkaloids (TOAs), a group of chemical antagonists that act upon the central nervous system and can greatly inhibit the positive effect of the Pentacyclic Oxindole Alkaloids (POAs). The POAs primarily affect the immune cells responsible for nonspecific and cellular immunity and demonstrate powerful immune system modulating properties. Amantilla is reported to be very effective in treating stress and anxiety, more so than Diazepam. The proprietary blend of Samento and Amantilla found in RelaxMedix has been shown to provide stronger effects than simply combining the products Samento and Amantilla.
