While guava is best known for its sweet tropical fruit, its leaves have also been used in traditional herbal medicine for centuries across Latin America, Asia, and parts of Africa. Today, guava leaves (Psidium guajava) continue to attract scientific interest because they contain a variety of naturally occurring antioxidants and plant compounds.

Although guava leaf tea is not a cure for diabetes, heart disease, or other chronic conditions, early research suggests it may have properties that support overall health when consumed as part of a balanced lifestyle.

Here’s what current evidence says about guava leaf tea, how to prepare it safely, and who should use caution.

What Makes Guava Leaves Unique?

Guava leaves naturally contain several beneficial plant compounds, including:

• Flavonoids
• Polyphenols
• Tannins
• Quercetin
• Antioxidants

Researchers continue to study these compounds for their potential effects on metabolic, digestive, and cardiovascular health.

Potential Health Benefits of Guava Leaf Tea

1. Rich in Antioxidants

Guava leaves contain antioxidants that help protect cells from oxidative stress caused by free radicals.

A diet rich in antioxidant-containing foods may support healthy aging.

2. Supports Healthy Blood Sugar Management

Several small studies have explored whether guava leaf extract may help support healthy blood sugar levels after meals.

While findings are promising, guava leaf tea should never replace diabetes medication or medical care.

3. Supports Heart Health

Early research suggests compounds in guava leaves may support cardiovascular wellness as part of an overall healthy lifestyle.

Maintaining heart health also depends on regular exercise, a balanced diet, and routine medical care.

4. Supports Healthy Cholesterol Levels

Some studies have investigated whether guava leaf preparations may contribute to maintaining healthy cholesterol levels.

More high-quality clinical research is still needed.

5. Promotes Digestive Comfort

Guava leaf tea has traditionally been used to support healthy digestion.

Some people drink it to help relieve occasional digestive discomfort.

6. Supports Immune Function

Its naturally occurring antioxidants contribute to the body’s normal immune defenses.

7. Supports Oral Health

Traditional herbal practices have used guava leaves in mouth rinses because of their natural plant compounds.

Research continues to investigate these effects.

8. Supports Skin Health

A nutrient-rich diet that includes antioxidant-containing plants may help support healthy skin.

9. Traditionally Used for Women’s Wellness

In some cultures, guava leaf tea has traditionally been consumed during menstruation to support comfort.

Scientific evidence remains limited.

10. Supports Overall Wellness

Like many herbal teas, guava leaf tea offers hydration along with naturally occurring plant compounds.
