Bitter Taste in Mouth in Traditional Chinese Medicine
In Traditional Chinese Medicine, a bitter taste in the mouth is classically associated with Liver Fire. Differentiation looks at whether there is irritability, rib-side distension, red eyes or a wiry rapid pulse. Classical formulas are matched to this pattern context rather than to the bitter taste alone. Accompanying signs such as tongue appearance, pulse quality and the presence of heat or cold help distinguish one presentation from another.
