The key to the effectiveness of the Kolorex range is the beautiful Kolorex Horopito herb. Kolorex Horopito is up to five times more effective than ordinary Horopito. It is grown only on Forest Herb's own certified organic farm, set in a temperate rainforest adjacent to a million acres of National park. Horopito helped the Maori people for centuries; now Kolorex Horopito is helping people around the world. Kolorex Horopito (Pseudowintera colorata) This New Zealand herb was traditionally used by the early European settlers and Maori who made tea of the leaves for stomach upsets. Modern science has confirmed the presence in Horopito of actives that promote a health microbial balance. Digestive Care contains only Kolorex Horopito. This Horopito has been laboratory verified to contain high levels of these actives. It is also Kolorex Horopito that gives Digestive Care its unique cleansing flavor. Peppermint leaf (Mentha x piperita) Refreshing Peppermint leaf infusions have traditionally been taken after meals to improve digestion. As a digestive aid, Peppermint helps to soothe digestion, settle the stomach, and relieve occasional nausea, heartburn, and flatulence. Anise Seed (Pimpinella anisum) Used traditionally in South America as a fold remedy, with a reputation as a digestive aid. Anise seed is used in Kolorex products to enhance the action of Horopito.
