This is an effective natural remedy has specific herbs to strengthen the immune system. It is a delicious and powerful formula that goes above and beyond being a simple syrup.  This formula has extra vitamin C by way of ascorbic acid. It also has Echinacea purpurea, Rosehips, Astragalus and Ginger root.  It has a great flavor because of the Vanilla bean, lemon peel, orange peel, clove bud and cinnamon.  (Which makes this formula a good source of bioflavonoids). Drink with Peppermint if the flu comes around to help promote free perspiration. This formula tastes so good, that it will be hard to resist drinking the whole bottle! Made with love and the highest quality ingredients possible including ionized water and 50 percent organic agave syrup. I include an information sheet telling about the herbs and any drug interactions.
