1. May Help Reduce Blood Sugar Spikes
Some small human and laboratory studies suggest that compounds in guava leaves may slow the breakdown and absorption of carbohydrates, which could reduce blood sugar spikes after meals.
More large, high-quality studies are still needed to confirm these effects.
2. Rich in Antioxidants
Guava leaves contain antioxidants that help protect cells from oxidative stress, which plays a role in many chronic diseases.
3. May Support Heart Health
Preliminary research suggests guava leaf compounds may help improve cholesterol and triglyceride levels in some people, though the evidence remains limited.
4. May Aid Digestion
Traditionally, guava leaf tea has been used to support digestive health and relieve occasional diarrhea or stomach discomfort.
