Scientists believe spice turmeric could help brain to heal itself. This is encouraging news for those affected by degenerative brain diseases. Researchers from Institute of Neuroscience and Medicine in Germany examined effects of properties found in turmeric on rats. The researchers injected rats with compound from turmeric. After scanning rodents' brains, they found that parts of brain known for nerve cell growth were more active. They say spice could lead to new drugs for treating strokes, Alzheimer's and other diseases. Lead scientist Dr Adele Rueger said it was possible compound could "boost the effectiveness" of our brain cells, and "help boost repair in brain".

Research is still in its infancy and more trials are needed to see what potential it has for humans. Dr Laura Phipps, from charity Alzheimer's Research UK, told BBC that it was too early to decide whether or not research will be groundbreaking. She said: "It is not clear whether results of this research would translate to people, or whether ability to generate new brain cells in this way would benefit people with Alzheimer's disease." She added: "We'd need to see further studies to fully understand this compound's effects in context of complex disease like Alzheimer's. Until then, people shouldn't take this as sign to stock up on supplies of turmeric for spice rack."
