Clinical Applications Of Licorice:
Licorice is one of the main adrenal tonics available in herbal medicine (the other is rehmannia). It is used alongside periods of adrenal fatigue to increase cortisol levels by inhibiting its breakdown.
Licorice is also especially useful for treating gastric and duodenal ulcers. In a similar effect, licorice is useful for soothing an inflammed gastrointestinal and repiratory tract.
The serotonin reuptake inhibition attribiuted to the plant give an explanation for the traditional antidepressant use of the herb. In clinical practice, this is a good addition to antidepressant formulas, but may not be potent enough to be used on its own.
Do not use licorice with hypertensive individuals. Cortisol increases with licorice use can lead to a further heightened blood pressure.
