Pirates in the garden of India

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.
