For years, guava leaf tea has been praised as a natural remedy for weight loss, regulating glucose levels, improving digestion, and strengthening the immune system.
However, a recent medical report surprised consumers: excessive consumption can cause unexpected effects.
Researchers from the National University of Natural Medicine point out that the leaves contain powerful antioxidants—flavonoids, polyphenols, and quercetin—that reduce inflammation, improve metabolism, and help control blood sugar.
However, excessive consumption can drastically lower glucose levels, causing dizziness, weakness, or fainting, as well as cramps, diarrhea, or reflux.
Experts recommend one or two cups daily and consulting a doctor if you have diabetes, are pregnant, or have digestive or kidney problems.
In moderation, this tea can support cardiovascular and skin health, which has sparked debate online about its benefits and risks.
