All Natural Ingredients Essiac Gold takes the original blend of Burdock Root Extract, Whole Plant Sheep Sorrel Extract, Slippery Elm Bark Extract, and Rhubarb Root Extract and enhances it by adding AHCC. AHCC Mushroom Extract AHCC is unique in that while most mushrooms contain primarily Beta Glucans, AHCC is rich in Alpha Glucans, a type of polysaccharide with very potent immune enhancing effects. Quick & Convenient Unlike the traditional Essiac herbal tea powder, there is no need to brew as the vital plant nutrients have already been extracted into a powerful herbal capsule that is 4x to 6x more concentrated than the brewed tea. Immune System Booster Essiac Gold is a natural herbal remedy that supports white blood cell count and NK cell creation. AHCC is supported by over 30 human clinical studies.
