Gopuram kumkum is one of the only 100% pure and natural kumkum products available today, made from all natural ingredients such as turmeric and lemon. Today most factory produced kumkum is made from artificial ingredients, such as powdered lead, which can be deadly if used over time. The heavy metals used in artificial kumkum can enter your body and cause serious health problems. If you use it on your forhead, the powdered lead can cause serious skin problems and balding. Please always use 100% natural kumkum, made traditionally from simple plants such as turmeric and lemon. We recommend Gopuram brand, as it is the only brand we have found to be made from 100% pure ingredients. A simple test to check the purity of kumkum is to smear a bit of it across the palm of your hand with your finger. Pure kumkum will reveal the bright yellow color of turmeric, whereas artificial kumkum remains red color. The tiny grains of pure kumkum are only red on the outer surface, but inside they are the yellow of turmeric powder. When you pinch and smear the grains, the yellow color will show through the red.
