Assalam Aleykum My lady physician Dr. Mrs. Sarfraz (MBBS) who also belongs to in-laws of my son, told me that diabetic patients frequently visit her clinic. Once a diabetic patient visited her and told that her sugar level got higher to 400. Then she brought down the higher level using the water-chestnut flour from 400 to 300 and then 200 and then even to normal level. She would use one spoon water chestnut flour with milk in the morning. It is also useful for feminine diseases. (S.K, Rawalpindi)
