Abstract : The use of alternative therapies to treat diabetes, including teas prepared with different plants, is widespread in Brazil. An ethnopharmacological survey indicated the prevalent use of a tea prepared with mango (Mangifera indica) leaves by Brazilian diabetic patients. The possible pharmacological actions of this decoction were investigated experimentally in normal rats, in streptozotocin-induced diabetic rats, and clinically in healthy volunteers. No hypoglycaemic effects were observed, and it is strongly suggested that mango tea cannot be recommended as an antidiabetic treatment.
