The key to the effectiveness of Kolorex is the high activity specimens of the traditional New Zealand herb, Horopito (Pseudowintera colorata).  These are grown organically on the Forest Herbs' own farm, set in a temperate rainforest adjacent to a million acres of pristine National Park. Each batch of Horopito leaves must pass an independent, university test for activity prior to use.  Forest Herbs combines ttradition with science to make available to the world the benefits of plants from New Zealand's unique environment.
