According to research published in the scientific journal Nutrition & Metabolism, guava leaf extract has effects on lipid metabolism and blood fat status. Clinical trials recorded that the group of people who maintained drinking guava leaf extract water for 12 consecutive weeks had a significant improvement in blood indicators.
Specifically, the amount of bad cholesterol (LDL) and neutral fats (triglycerides) decreases, while the amount of good cholesterol (HDL) protecting the cardiovascular system is not affected.
This effect comes from the group of antioxidants in young guava leaves, typically Quercetin and gallic acid. When entering the body, these compounds participate in the process of preventing the oxidation of LDL-cholesterol.
Thanks to minimizing oxidation, guava leaves support the body to limit the formation of plaque on blood vessel walls. At the same time, the active substances in guava leaves also support the liver in dissolving and eliminating excess lipids from the circulatory system through natural excretion.
This process helps blood vessels circulate stably, contributing to preventing cardiovascular disease risks.
Not only lowering blood fat, guava leaves also have a strong effect on diabetes. The natural compounds in guava leaves have the ability to inhibit the enzyme Alpha-glucosidase in the intestines, breaking down starch into sugar.
The ability to stop diarrhea, thanks to the content of Quercetin, when it enters the digestive tract, this compound can inhibit and excrete disease-causing bacteria such as E. coli or Staphylococcus aureus.
To use guava leaves safely, you can take about 5-10 fresh young guava leaves or dried leaves, soak and wash them and boil them with 500ml of water for 15 minutes. Boiled guava leaf water has a mild acrid taste, the appropriate time to drink is about 30 minutes after meals to support the metabolism process.
Due to the high tannin content in guava leaves, you should not drink guava leaf water instead of filtered water or use it on an empty stomach to avoid stomach irritation and constipation. In particular, pregnant women, people with sensitive digestive systems or those undergoing blood fat medication should consult a doctor before use.
