Herbal teas have been used in traditional wellness practices for generations around the world. Among the many popular combinations is an infusion made with guava leaves, bay leaves, and Mexican oregano (or Cuban oregano). These plants are valued for their natural antioxidants, aromatic compounds, and long history of culinary and traditional use.
Although these herbs contain beneficial plant compounds, they do not cure diabetes, high blood pressure, poor circulation, cancer, or any other chronic disease. Instead, they can be enjoyed as part of a balanced diet and healthy lifestyle.
In this guide, you’ll learn about the nutritional properties of each ingredient, how to prepare the tea safely, and what current research suggests about their potential benefits.
Why Herbal Leaf Teas Remain Popular
Many traditional herbal teas are appreciated because they are:
- Naturally caffeine-free
- Rich in plant antioxidants
- Easy to prepare
- Affordable
- Pleasant to enjoy hot or cold
Drinking herbal tea can also contribute to your daily fluid intake while encouraging healthy lifestyle habits.
Main Ingredients
This traditional infusion combines three commonly used leaves.
Mexican Oregano (Cuban Oregano)
Use approximately:
- 4 fresh leaves
Mexican oregano (Plectranthus amboinicus) is different from common culinary oregano. It has aromatic leaves rich in naturally occurring essential oils and plant antioxidants.
Bay Leaves
Use:
- 4 dried or fresh bay leaves
Bay leaves are widely used in cooking and contain aromatic compounds, polyphenols, and antioxidants.
Guava Leaves
Use:
- 6 fresh guava leaves
Guava leaves contain naturally occurring:
- Polyphenols
- Flavonoids
- Antioxidants
- Vitamin C (primarily in fresh leaves)
They have been widely studied for their antioxidant properties.
How to Prepare the Herbal Tea
Ingredients
- 4 Mexican oregano leaves
- 4 bay leaves
- 6 guava leaves
- 4 cups (1 liter) water
Instructions
- Wash the fresh leaves thoroughly.
- Add all leaves to a saucepan.
- Pour in the water.
- Bring to a gentle boil.
- Reduce the heat and simmer for approximately 10–15 minutes.
- Remove from heat.
- Cover and allow the tea to steep for another 5–10 minutes.

Can You Store It?
Yes.

Warm gently before drinking if desired.
Potential Benefits of the Ingredients
Although more high-quality human research is needed, each ingredient contributes valuable nutrients and plant compounds.
1. Rich in Antioxidants
All three leaves provide naturally occurring antioxidants.
Antioxidants help protect cells from oxidative stress caused by free radicals.
A diet rich in antioxidant-containing foods supports healthy aging and overall wellness.
2. Supports Digestive Wellness
Bay leaves and Mexican oregano have traditionally been used to promote comfortable digestion.
Many people enjoy herbal teas after meals to help with occasional:
- Bloating
- Gas
- Mild indigestion
Scientific evidence remains limited, but these traditional uses continue today.
3. May Support Healthy Blood Sugar as Part of a Balanced Diet
Some preliminary studies have explored compounds found in bay leaves and guava leaves for their possible effects on glucose metabolism.
However:
- Research is still ongoing.
- Results are mixed.
- These herbs should never replace diabetes medication.
People living with diabetes should continue following their healthcare provider’s treatment plan.
4. Supports Cardiovascular Wellness
A diet rich in fruits, vegetables, herbs, and whole foods contributes to heart health.
The antioxidants found in these leaves may help support healthy blood vessels as part of an overall healthy eating pattern.
No herbal tea has been proven to lower blood pressure or improve circulation on its own.
5. Encourages Healthy Hydration
Replacing sugar-sweetened beverages with herbal tea can help increase daily fluid intake.
Good hydration supports:
- Digestion
- Kidney function
- Circulation
- Temperature regulation
Understanding the Science
Many online articles claim herbal teas can cure chronic illnesses.
Current scientific evidence does not support claims that this tea can:
- Cure diabetes
- Treat hypertension
- Prevent blood clots
- Cure cancer
- Replace prescription medications
Some laboratory studies have investigated antioxidant and anti-inflammatory properties of individual plant compounds, but these findings should not be interpreted as proven medical treatments in humans.
Best Time to Drink Herbal Tea
Many people enjoy herbal infusions:
- In the morning
- Between meals
- After lunch or dinner
- During cool evenings
There is no scientific evidence that drinking herbal tea on an empty stomach provides additional health benefits.
Healthy Habits That Truly Support Long-Term Wellness
Instead of relying on one beverage, experts recommend combining nutritious foods with proven healthy habits.
These include:
- Eating plenty of fruits and vegetables
- Staying physically active
- Maintaining a healthy body weight
- Sleeping well
- Managing stress
- Avoiding smoking
- Limiting excess alcohol
- Following routine medical care
These lifestyle choices have far stronger scientific evidence than any single herbal remedy.
Important Precautions
Although these herbs are commonly used in cooking and traditional teas, moderation is important.
Consult your healthcare provider before regular use if you:
- Have diabetes
- Have high blood pressure
- Have liver or kidney disease
- Are pregnant or breastfeeding
- Take prescription medications
Herbal ingredients may interact with certain medications.
Never stop prescribed treatment without medical guidance.
Frequently Asked Questions
Can this tea cure diabetes?
No. There is no scientific evidence that this herbal tea cures diabetes. A balanced diet may support metabolic health, but diabetes requires ongoing medical management.
Does it prevent cancer?
No food or herbal tea has been proven to prevent cancer on its own. A healthy lifestyle—including not smoking, maintaining a healthy weight, eating a nutritious diet, and following recommended cancer screenings—offers the strongest evidence for reducing cancer risk.
Can I drink it every day?
Most healthy adults can enjoy herbal teas in moderation. If you have chronic health conditions or take medications, discuss regular herbal use with your healthcare provider.
Final Thoughts
This traditional tea made with guava leaves, bay leaves, and Mexican oregano is a flavorful herbal infusion rich in natural antioxidants and aromatic plant compounds. It can be a pleasant way to increase hydration and enjoy traditional herbal ingredients as part of a balanced lifestyle.
While these herbs have a long history of traditional use, they should never be viewed as miracle cures or replacements for evidence-based medical care. Lasting health comes from consistent healthy habits, nutritious foods, regular physical activity, quality sleep, and partnership with your healthcare provider.
Enjoy herbal teas for their flavor, tradition, and nutritional value—and let them complement, not replace, a healthy way of living.
