not necessarily mean drinking its tea will prevent or cure disease.
Traditionally Used for Digestive Comfort
Guava leaves have a long history of traditional use for digestive complaints.
In some cultures, a tea made from the leaves has been consumed when people experience occasional stomach discomfort or loose stools.
Some laboratory and small human studies have investigated guava-leaf preparations in relation to digestive health, but the evidence is not strong enough to consider guava leaves a replacement for appropriate medical treatment.
If diarrhea is severe, persistent, or accompanied by dehydration, fever, blood, or significant pain, medical advice is more important than relying on herbal remedies.
Possible Effects on Blood Sugar
Another area of interest is blood-glucose regulation.
Research has explored whether compounds in guava leaves may influence carbohydrate digestion or glucose metabolism. Some studies have reported potentially beneficial effects, but results vary, and much of the evidence is still limited.
