Benefits of coca tea
Energy
The leaves of the coca plant contain compounds that provide a stimulating effect on your body, similar to caffeine, which can increase energy and mental concentration, says Tenney. Coca tea contains a compound called inulin, a type of polysaccharide of natural origin produced in some plants that provides a stimulating effect. The stimulating effect of coca tea is similar to that of coffee, but through different cellular mechanisms due to the lack of caffeine in the leaves of the coca plant.
Immune system
Coca tea contains high concentrations of vitamins that may have antioxidant properties. Vitamins A, B-2, B-6, C and E are present in coca leaves, all of which can help stimulate the functioning of your immune system, which increases your body's ability to potentially destroy compounds toxic in the bloodstream. According to the U.S. Department of Health and Human Services, the antioxidant properties of vitamins C and E can help reduce the risk of developing various types of cardiovascular disease.
Digestion and altitude sickness
According to "The New Encyclopedia of Vitamins, Minerals, Supplements, and Herbs", coca tea has been used in South America for centuries to reduce the gastrointestinal discomfort associated with indigestion and altitude sickness. Drinking coca tea and chewing coca leaves can relieve the symptoms of altitude sickness, including nausea, upset stomach, diarrhea and vomiting. This effect can be due to the presence of several alkaloids, as well as several B vitamins, which can help improve blood flow and oxygen absorption at high altitudes.
