These phytocemicals are capable of stimulating the bitter recpetors at the back of the tongue. These bitter recpetors in turn stimulate and promote digestive function and thereby general health. The stimulating effect is most obvious when digestion is below par and bitters are best used when food is actually in the stomach. Take a dose 5-15 minutes before a meal, sipping the does of tincture in 20ml of water.
Examples include Wormwood and Gentian.
