What Is Guava Leaf Tea?

Guava leaf tea is an herbal infusion made from the leaves of guava (Psidium guajava), a tropical tree in the Myrtaceae family. The leaves contain bioactive compounds such as tannins, flavonoids, and essential oils, which are associated with antioxidant, anti-inflammatory, antimicrobial, and anti-diarrheal activity.

Unlike the sweet fruit used in juices and desserts, the leaves have a more bitter, astringent taste—a common characteristic of tannin-rich medicinal plants.

10 Benefits of Guava Leaf Tea

1. Supports Diarrhea Relief and Digestive Upset

One of the most traditional uses of guava leaf tea is for diarrhea and intestinal discomfort. Tannins may help reduce intestinal inflammation and support the body during mild GI disturbances.

2. Helps Support Healthy Blood Sugar Levels

Research suggests guava leaf compounds may support post-meal glucose control, making it of interest for people with prediabetes or type 2 diabetes—always with medical guidance, especially if medications are involved.

3. Immune and Infection Support

Guava leaves have been studied for antimicrobial activity, which may help support the body during common seasonal issues.

4. May Ease Menstrual Cramps

Traditionally, guava leaf tea is used for abdominal cramping, including menstrual discomfort, due to its potential soothing and anti-inflammatory properties.

5. Can Assist Weight-Management Routines

Guava leaf tea may help support weight goals indirectly by promoting hydration and offering a mild appetite and digestion-support effect. It is not a “fat burner,” but it can fit into a balanced routine.

6. Supports Oral Health

Used as a mouth rinse, guava leaf tea is popular for bad breath, gum irritation, and mouth sores, thanks to its astringent and antimicrobial profile.

7. Supports Heart Health Markers

Some studies associate guava leaf intake with support for cholesterol balance, including LDL (“bad cholesterol”), as part of a broader healthy lifestyle.

8. Provides Antioxidant Protection

Guava leaves contain antioxidants that help combat oxidative stress, which is linked to cellular aging and chronic health concerns.

9. External Use for Skin Cleansing

Cooled tea can be used externally as a wash or compress to help cleanse minor skin irritation and support comfort.

10. Respiratory Comfort Support

By tradition, guava leaf tea is also used to support throat and respiratory comfort, particularly when irritation is related to inflammation.

How to Prepare Guava Leaf Tea Correctly

The preparation method matters. For guava leaves, a covered infusion is typically the best approach to preserve delicate compounds while extracting tannins properly.

Ingredients

• 1 tablespoon dried guava leaves (or 3 fresh leaves, well washed)
• 1 cup (250 ml) filtered water

Directions

1. Heat water until it just reaches a boil.
2. Turn off the heat, add the leaves, and cover.
3. Steep for 10 minutes.
4. Strain and drink warm.

How Often to Drink

• Common use: up to 2 cups per day
• For digestive support, many people prefer drinking it after meals.

Tip: If the tea feels too astringent, reduce the leaf amount slightly or steep for a shorter time.

How to Use Guava Leaf Tea Externally

After preparing the tea, let it cool completely and use as:

Contraindications and Safety Notes

Even natural teas require caution. Avoid or use only with professional guidance if you are:

• Pregnant (unless your clinician approves)
• Breastfeeding (safety data is limited)
• Giving it to children under 6
• Experiencing severe constipation (tannins may worsen it)
• Taking diabetes medications (monitoring may be needed due to possible glucose-lowering effects)

If you use medicinal teas frequently, it’s wise to inform your healthcare professional—especially if you take prescription medications.
