In Europe it is used for weight loss, physical and mental fatigue, nervous depression, rheumatic pains and psychogenic and fatigue related headaches. In Germany it has become popular as a weight-loss aid. Yerba mate is the subject of a German monograph which lists its approved uses for mental and physical fatigue.
In France yerba mate is approved for the treatment of asthenia (weakness or lack of energy), as an aid in weight-loss programs and as a diuretic.
It also appears in the British Herbal Phamacopoeia (1996) and indicated for the treatment of fatigue, weight loss and headaches. In the U.S., Dr. James Balch, M.D. recommends yerba mate for arthritis, headaches, hemorrhoids, fluid retention, obesity, fatigue, stress, constipation, allergies and hay fever, and states that it “cleanses the blood, tones the nervous system, retards aging, stimulates the mind, controls the appetite, stimulates the production of cortisone and is believed to enhance the healing powers of other herbs.”
