Vernacular name in Telugu: Podapatri. Leaves when chewed neutralizes the taste of sugar. Leaves are used as remedy for diabetes, cough and biliousness. One leaf per day is recommended for diabetics in ehnomedicine. I am not sure weather it cures diabetes or not. Because of numbness of tongue we couldnot relish sweet taste.
