Researchers are coming by evidence that herbs like brahmi, associated with the ayurveda system of medicine, can help ward off Alzheimer's
Although what exactly causes Alzheimer's is not known, sufferers experience inflammation of the brain, deposits of beta amyloid, traces of heavy metals and signs of oxidative stress.
Brahmi, a semi-aquatic plant, acts on all of these, said Con Stough, director of the National Institute of Complementary Medicine (NICM) involved in trials underway at Swinburne University of Technology Brain Sciences Institute (BSI).
"It has an anti-inflammatory effect, is an antioxidant and collates and removes heavy metals and beta amyloid," he said.
Two trials with a brahmi extract called CDRI08, conducted over 90 days, have shown improvements in working memory, particularly spatial memory accuracy.
