Is stevia juice beneficial for diabetics?

Q: My wife, 40 years old, is suffering from diabetes from the last one year. She is on insulin of 18 + 12 units of Mixtard. Even though the doctor says that the blood sugar levels are under control but due to elevated SGPT and SGOT levels, she needs to continue Insulin. One of my friends whose wife is on insulin has used stevia juice for last 6 months and has got beneficial results. We are tempted to do the same but would like to know if there is any harm?

A:No harm in trying stevia juice, but no scientific studies have shown any significant benefit. But do continue insulin, if required, under the care of your physician.
