To most Indians, turmeric or haldi is a part of growing up, a magic cure-all for the excesses of childhood. A classic "grandmother's remedy", the virulent yellow powder or paste has been applied to the scrapes and cuts of generations of children. But in the US, two scientists were granted a patent to use this plant extract in its powder form for healing wounds. The scientists claimed they were the first to use turmeric (Curcuma longa) for this purpose. The ensuing public outcry prompted the government in Delhi to file a case against the American patent at the US Patent and Trademark Office in Washington DC.
