Herbal teas are derived from the leaves, roots, flowers and other parts of plants. While some herbal teas may have sour or bitter tastes, reflecting their level of acidity or alkalinity, once they are digested and assimilated, the vast majority have an alkalizing effect. This means that they raise the body's pH once they are digested and assimilated. Certain herbal teas are particularly noted and sought after for their alkalizing benefits. pHion Alkaline Tea is a perfect blend that helps support correct body chemistry.
