Like many spices, turmeric (Curcumalonga) has a long history of use in traditional medicine. Curcumin is the active part of turmeric and aside from giving curry its vibrant yellow colour, turmeric is also scientifically-proven to have potent anti-inflammatory and antioxidant properties, it may help improve symptoms of depression, as well as arthritis, and has the potential to prevent heart disease.

These positive health properties have also been recognised by conventional medicine. 

Curcuminoids are a group of natural phenols obtained from the Curcuma longa plant (ginger family). Curcuminoids have been used for centuries in Ayurveda and Traditional Chinese Medicine. Some curcuminoids have very good antioxidant properties, others may have anti-inflammatory effects.

Turmeric products contain an extremely intense yellow pigment, which can lead to difficult to remove stains (sensible to light exposure). 

It is difficult to absorb enough curcumin from diet, therefore supplements are the best way.
