For years, guava leaf tea has been celebrated as a natural remedy for weight loss, blood sugar regulation, better digestion, and a stronger immune system. Its reputation as a safe herbal drink has made it popular in many households.
But a recent medical report has raised important concerns: drinking too much guava leaf tea may have unexpected side effects.
What Science Says
Researchers from the National University of Natural Medicine highlight that guava leaves are rich in powerful antioxidants—flavonoids, polyphenols, and quercetin. These compounds help reduce inflammation, improve metabolism, and support blood sugar control.
In moderation, the tea can also promote cardiovascular health and improve skin quality, making it a valuable addition to a balanced lifestyle.
Potential Risks of Overconsumption
Despite its benefits, excessive intake can trigger unwanted effects, including:
- Dangerously low blood sugar levels, leading to dizziness, weakness, or fainting
- Digestive discomfort, such as cramps, diarrhea, or acid reflux
- These risks are especially concerning for people with pre-existing health conditions.
Expert Recommendations
- Limit consumption to 1–2 cups per day
- Consult a doctor before use if you have diabetes, digestive disorders, kidney issues, or are pregnant
- Use it as a supportive remedy, not as a replacement for medical treatment
Conclusion
Guava leaf tea offers real health benefits thanks to its antioxidant and metabolic properties. However, like many natural remedies, the key lies in moderation. When consumed responsibly, it can support wellness; when overused, it may do more harm than good.
