Bhringrajasava can be used in pre-diabetic cases with no side effects... but the condition of pre-diabetes demands more attention... you have to change your lifestyle... panchakarma can help you beyond lifestyle changes

Better go for tablets than asava,as you are prediabetic,.there are many tablets like. Heptin forte,livomyn tab,arogyavardhini vati
