Leaves of the guava tree are edible and often used as a condiment with dishes such as sour fermented pork sausage and salads. Additionally, guava leaves can be brewed to make a nutritious drink, offering a plethora of health benefits.
Nutritional Value of Guava Leaves
Guava leaves are a treasure trove of essential vitamins and minerals. They are particularly rich in vitamin C, a powerful antioxidant that boosts immunity and slows down the aging process. The leaves also contain ample amounts of vitamin A, beneficial for eye health and skin complexion. Guava leaves are a good source of minerals like potassium, magnesium, zinc, and copper, which help maintain electrolyte balance and support nerve and muscle function.
The leaves are also a good source of dietary fiber, both soluble and insoluble, which aids digestion. Polyphenols, flavonoids, tannins, and carotenoids present in the leaves exhibit strong antioxidant properties, protecting cells from damage and reducing the risk of chronic diseases.
Folate, a type of vitamin B found in guava leaves, promotes heart and nerve health.

Health Benefits of Guava Leaf Tea
Brewing guava leaves to make a tea is a common practice, and this beverage offers several health advantages.
- Aids in Treating Diarrhea
Guava leaves have been used in traditional medicine to treat diarrhea. The tannins and flavonoids present in the leaves have antibacterial properties, help tighten the intestinal mucosa, and reduce fluid secretion. They also inhibit the activity of disease-causing bacteria such as E. coli and Staphylococcus aureus. Consuming guava leaf tea can help alleviate abdominal pain and diarrhea.
To use guava leaves for diarrhea treatment, simply boil about 30 grams of clean guava leaves to make a tea, or chew on young guava leaves to relieve symptoms.
- Controls Blood Sugar and Supports Diabetes Management
Research suggests that guava leaves can inhibit the activity of the enzyme alpha-glucosidase, helping to regulate blood sugar levels effectively.
- Promotes Cardiovascular Health
The high content of antioxidants and soluble fiber in guava leaves contributes to lowering LDL (bad) cholesterol and increasing HDL (good) cholesterol levels in the blood, thereby improving blood pressure. Maintaining healthy cholesterol and blood pressure levels reduces the risk of atherosclerosis, heart attacks, and strokes. Potassium in guava leaves further supports cardiovascular health by maintaining electrolyte balance.
- Aids in Weight Loss
Guava leaves can be a helpful addition to a weight loss regimen. The compounds polyphenol and flavonoid present in the leaves inhibit the conversion of starch into sugar, thereby reducing fat accumulation. Drinking guava leaf tea after meals or blending guava leaves with fruits and vegetables into smoothies, along with a healthy diet and regular exercise, can support weight loss efforts.
- Boosts Immunity and Helps with Allergies
Guava leaves are rich in iron and vitamin C, which strengthen the immune system. They also contain compounds that help release histamine in the body, reducing allergy symptoms such as itching and hives.
- Improves Digestion
Guava leaf tea contains digestive enzymes and fiber, which help improve digestion and soothe the stomach.
Precautions When Using Guava Leaf Tea
While guava leaf tea offers numerous health benefits, it should be consumed in moderation. It is recommended to limit intake to 1-2 cups per day. Individuals with low blood pressure, stomach issues, or those undergoing medical treatment should consult a healthcare professional before incorporating guava leaf tea into their routine.
In conclusion, guava leaf tea is a natural gift offering a range of health benefits, including weight loss support, improved digestion, and skin health, when consumed appropriately.
