Researchers from the Pohang University of Science and Technology found evidence linking the flavonoid found in hibiscus tea to activate an immune response against Alzheimer’s disease, which is often noted as a hereditary disease. The procedural methods of the experiment consisted of the observation of mice who were positive for Alzheimer's disease. The mice received an injection of the flavonoid and hibiscus tea and were observed to have improved cognitive behaviors upon injection. The research from the experiment concluded that the Hibiscus tea flavonoid, known as gossypetin, can stimulate microglia, the main cell responsible for cognitive function within the central nervous system. The stimulation of microglia was noted by researchers in the study to help alleviate build up and production of the amyloid beta protein noted to be the primary cause of the cognitive decline often associated with Alzheimer’s disease. The research findings proposed from the experiment can be very beneficial for future research directed towards Alzheimer’s disease, which continue to affect millions of people throughout the world.
