The Bottom Line
Guava leaves have an interesting history in traditional medicine and contain several naturally occurring plant compounds. However, there is not enough reliable human evidence to say that guava-leaf tea can cure kidney disease, repair damaged kidneys, or reliably dissolve kidney stones.
The preparation described online should therefore not be presented as a proven kidney treatment, and there is no scientifically established dosage of guava leaves for treating kidney disease.
If you’re concerned about your kidneys, the most useful first step is identifying the underlying problem through appropriate blood and urine testing.
A cup of herbal tea may be part of someone’s traditional routine, but it should never replace medical care when kidney symptoms are present.
Medical disclaimer: This article is for educational purposes only and does not diagnose, treat, cure, or prevent kidney disease. If you have known kidney disease, are pregnant, take prescription medication, or have significant urinary or kidney symptoms, consult a qualified healthcare professional before using guava leaves or any other herbal preparation.
