The uses for Licorice are vast and varied. It is known as an adrenal gland tonic for those with fatigue or ongoing stress. It may help the stressed adrenal gland to maintain its production of adrenaline, cortisone and aldosterone when over burdened. Licorice can increase the hormone aldosterone, which makes one hold more water. This may help hydrate a dry body, decrease the frequent need to urinate, but increase the volume of urine.
