Quality and Manufacture The greatest phytochemical properties of Cat?s Claw lie in its bark. After harvest and careful selection, the plant material undergoes a process of cold percolation in order to extract the active constituents into tincture form. This method employs a gradient circulation of the solution which keeps the plant ingredients in perpetual contact with the ethanol. More efficient than maceration, this technique ensures there is less waste of precious plant materials.Indigo Herbs products naturally empower optimum health and nutrition.
