Health science has started to back up what Indians have known for a long time — it really does contain compounds with medicinal properties
These compounds are called curcuminoids, the most important of which is curcumin.
Curcumin is the main active ingredient in turmeric. It has powerful anti-inflammatory effects and is a very strong antioxidant.
However, the curcumin content of turmeric is not that high. It’s around 3%, by weight
Most of the studies on this herb are using turmeric extracts that contain mostly curcumin itself, with dosages usually exceeding 1 gram per day.
