Indian scientists, in a recently conducted research, have found that the turmeric spice (obtained from the rhizome of the Curcuma longa plant) can prove beneficial in the blockage of a biological pathway which leads to the progression of diabetic retinopathy, a complication that can cause blindness, if not treated at the right stage. A study showing that the incidence of diabetic retinopathy was much lower in Indians as compared to Europeans made the researchers curious about the ingredients of Indian diet that were helpful in preventing the disease. Curcumin’s anti-angiogenic effects against cancer, the scientists guessed, may also curb the growth of new blood vessels in the retina.
