Support healthy cardiovascular system function with Cactus liquid extract from Herb Pharm. We prepare our Cactus Extract from the fresh (undried) young tender stem of Selenicereus spp. cactus which is Sustainably Wildcrafted in its natural habitat. To assure optimal extraction of Cactus' bioactive compounds, we hand-harvest only the young tender stem which is then taken directly to our laboratory and promptly extracted while still fresh and succulent. Caution: Do not exceed recommended dose. Use with caution in persons taking heart medications.
