Aid in Weight Loss:
Guava leaves aid in weight loss by preventing the complex starches from being converted into sugars. For this purpose, the carbs must be broken down in the liver for use by the body and guava leaves prevent the transition of carbohydrates to usable compounds.
Beneficial for Diabetics:
According to research conducted by the Yakult Central Institute in Japan, guava leaf tea can effectively lower blood glucose in diabetics by reducing the alpha-glucosidease enzyme activity. Moreover, it prevents the absorption of sucrose and maltose by the body, thereby lowering blood sugar levels. Drinking guava leaf tea for 12 weeks lowers the blood sugar levels without increasing insulin production.
Research has proved that drinking guava leaf tea for 3 months can lead to reduction in LDL or bad cholesterol and triglycerides without any adverse effect on good cholesterol. Besides, the guava leaves are a great liver tonic.
Treatment of Diarrhea and Dysentery:
Guava leaves are herbal remedy for diarrhea and dysentery. For treating diarrhea, boil 30 grams of guava leaves with a handful of rice flour in 1-2 glasses of water and drink this concoction twice a day. In case of dysentery, cut the roots and leaves of guava plant and boil them for 20 minutes at a temperature of 90 degrees Celsius. Strain the water and drink in moderation until relieved.
