Use ginseng for chronic fatigue, convalescence, lethargy, depression, and chronic infections related to immune weakness, especially if you’re over forty-five. Ginseng is particularly revered for its digestive-strengthening powers. Try it if you have problems like gas or malabsorption or if you commonly experience a feeling of fullness, even after eating only small meals. Since good digestion is the key to vitality, by improving its efficiency you also strengthen your immune system and hormone balance.
