Many medicines have come from nature. Both aspirin and quinine were derived from the bark of trees and digitalis, a potent heart medicine, comes from a flower.
Researcher Dave Schubert from the Salk Institute in San Diego has been looking at turmeric, a spice that's commonly used, particularly in South Asia.
圣地亚哥索克研究机构的研究员大卫·舒伯特正在对姜黄——一种尤其在南亚被人广泛食用的香料进行研究。
Schubert and other researchers believe that part of the reason for that low level of brain injury in India is that, over a lifetime, consuming turmeric may actually have a protective effect on the brain and nervous system.
He found that at least one compound, curcumin, has protective effects in the brain cells of lab animals with neurological injuries.
他发现这其中至少有一种成分——姜黄色素可以对用于实验的患有神经损伤的动物的脑细胞起到有效的保护作用。
