Because neem is a tonic and a revitalizer, it works effectively in the treatment of diabetes, as well. More than a disease that requires change of diet, diabetes is the leading cause of blindness in people ages twenty-five and seventy-four; it also damages nerves, kidneys, hear and blood vessels; it may even result in the loss of limbs.
Incurable, it can be treated in a variety of ways. One recommendation is to take one tablespoon (5ml) of neem leaf juice daily on an empty stomach each morning for three months. An alternative is to chew or take in powder form ten (10) neem leaves daily in the morning. Some studies have shown that oral application of neem leaf extracts reduced a patient’s insulin requirements by between 30 and 50 percent for nonkeytonic, insulin fast and insulin-sensitive diabetes.
Because neem has been found to reduce insulin requirements by upto 50 percent, without altering blood glucose levels, the Indian Government has approved the sale of neem capsules and tablets through pharmacies and clinics for this purpose. Many of these pills are made of essentially pure, powdered neem leaves.
Karnim, one medication that contains neem and a number of other herbs, available in many countries for treating diabetes, was found to lower blood sugar by more than 50 percent in twenty weeks and to maintain that level thereafter.
