Yang-Xue-Qing Nao (YXQN) is a Chinese herb which has been shown to improve sleep in Parkinson’s patients. Now, U.S. and Chinese researchers have shown that it counteracts cognitive decline in Alzheimer’s mice. The mice received high doses of the herb over two months and researchers found that beta amyloid plaque levels were reduced by as much as 50 percent. The herb targeted plaques in the hippocampus (the region in the brain responsible for memory) and increased neurons’ ability to protect against the formation of new plaques.
The herb consists of 11 natural remedies such as Angelica Sinusus and White Peony Root. It’s used in Chinese medicine for improving blood flow to the brain, encouraging anti-oxidation, the protection of neurons and the regulation of enzymes targeting the nervous system. More scientists are turning their attention to the role of decreased blood flow to the brain in the pathology of neurodegenerative diseases like Alzheimer’s. Some are even arguing for more research into increasing cerebral blood flow as a potential treatment for Alzheimer’s disease. Researchers believe the results of this study strongly suggest that YXQN could be a potential medicine for Alzheimer’s and provide new evidence for drug research and development.
