Turmeric may boost people's memories by nearly 30 percent and ease depression, new research suggests.Taking a compound found in the popular Indian spice, known as curcumin, causes people to have significantly less protein build-up in the regions of the brain associated with memory and emotion, a US study found.
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. Inflammation has previously been linked to both dementia and severe depression.
Study author Dr Gary Small from the University of California, LA, said: 'These results suggest that taking this relatively safe form of curcumin could provide meaningful cognitive benefits over the years.'
Curcumin has been used as a herbal remedy in arthritis, cancer and heart disease.
