- Guarumo, or Cecropia obtusifolia (Cecropiaceae), is a fruit-bearing tree that grows in the tropical Americas. Its leaves are used in folk medicine for the treatment of type 2 diabetes mellitus. A number of closely related Cecropia species (including Cecropia peltata, Cecropia palmate, and Cecropia obtusifolia) are similar in appearance, chemical makeup, and traditional medicinal uses.
- Traditionally, Cecropia obtusifolia has been used by Palikur indigenous tribes in Guyana and the Amazon basin, as well as by traditional healers in Cuba and other parts of Central and South America, for various ailments, including arteriosclerosis (hardening of the arteries), asthma, bone fractures, bruises, diarrhea, fever, genitalia infections, gonorrhea, herpes, kidney disorders, liver disorders, mouth and tongue sores, obesity, Parkinson's disease, rheumatic inflammation, skin diseases, warts, and wounds. Animal studies suggest that Cecropia obtusifolia leaf extracts may lower blood pressure and have diuretic effects.
- Human studies suggest that Cecropia obtusifolia may reduce blood sugar levels in some patients with type 2 diabetes. However, additional research is needed to confirm these findings.
