Past studies have linked the onset of Alzheimer's disease to the accumulation of protein plaques in the brain.
Curcumin,
which gives turmeric its yellow color, is thought to improve memory and
boost mental health due to its anti-inflammatory properties.

provide meaningful cognitive benefits over the years.'
Curcumin has been used as a herbal remedy in arthritis, cancer and heart disease.
