Certain herbs actually enhance the body’s ability to retain moisture and maintain fluid balance. Astringent herbs help to tighten leaky tissue that may be allowing fluids to escape, mineral rich herbs provide electrolytes that are crucial to fluid balance, and herbs rich in mucilage are wonderful for moistening dry, irritated mucous membranes.  Herbal infusions offer a little something extra: they not only hydrate but can also tone, soothe, and restore tissue function.
