Science or Snake Oil: can turmeric really shrink tumours, reduce pain and kill bacteria?

Turmeric is a yellow coloured spice widely used in Indian and South East Asian cuisine. It’s prepared from the root of a plant called Curcuma longa and is also used as a natural pigment in the food industry.

In the literature, curcumin is reported to be an antioxidant that protects the body against damage from reactive molecules. These are generated in the body as a result of metabolism and cause cell damage (known as free radicals).
