Stevia in water has diuretic and hypotensive effects, and quenches thirst.
Stevia, also called sweet tea, is native to the alpine meadows on the border of Paraguay and Brazil in South America. Now it has been introduced and planted in Hebei, Shaanxi, Beijing, Jiangsu, Hunan, Fujian and Yunnan. Stevia can be harvested in spring, summer and fall, and can be used fresh or dried after removing the stems and branches.
Stevia is sweet in taste and flat in nature, and enters the lung and stomach meridians, with the effect of generating fluids to quench thirst and lowering blood pressure. It is used to treat thirst and hypertension. It is usually taken as a decoction for internal use, and can also be steeped in boiling water as a tea substitute.
It is recommended that stevia be taken in moderation under the guidance of a doctor, and the drug should not be abused to avoid danger.
