Medical guidance on guava leaf tea consumption

Medical professionals in Vietnam have provided guidance regarding the consumption of guava leaf tea for its metabolic and digestive benefits. While the tea contains polyphenols, flavonoids, and tannins that may assist in managing blood sugar, cholesterol, and diarrhea, experts warn against excessive use.

Health professionals from Medlatec General Hospital advise that highly concentrated tea or overconsumption can cause bloating, constipation, or gastrointestinal discomfort due to high tannin content. It is recommended to consume the tea approximately one hour after meals and to avoid using it as a primary hydration source. Individuals with constipation or those on diabetes and blood pressure medications are advised to consult doctors before use.

Addressing concerns about organ health, Dr. Ngô Đức Phương of the Institute of Traditional Medicine stated there is no scientific evidence that normal doses of guava leaf water cause kidney damage in healthy individuals. Dr. Huỳnh Tấn Vũ from the University Medical Center Ho Chi Minh City added that in traditional medicine, the leaves are used to clear heat and detoxify, noting their potential cardiovascular benefits.
