Does the guava-leaf 'diabetes cure' claim actually hold up?
The assertion that two Guava leaves can reverse Diabetes mellitus within 15 days lacks evidence. Though Dr Annusuiya, MD Scholar at the All India Institute of Ayurveda, says guava-leaf extracts may exert modest alpha-glucosidase inhibition and support glycaemic control in type-2 diabetes, no human trial demonstrates reversal or cure. The original social-media claim is therefore rated false.
