Eating more purslane can prevent Alzheimer's disease. This scientific research result of Wuhan No. 1 Hospital was recently approved by the expert group of Wuhan Science and Technology Bureau. After three years of dedicated research and repeated large-scale animal experiments, the research team led by Yu Nancai, chief pharmacist of the Central Laboratory of Wuhan No. 1 Hospital, discovered for the first time from a molecular biology perspective that Purslane water extract can play a protective role in brain tissue damage, resist aging, and enhance immunity. Yu Nancai said that purslane is rich in flavonoids, polysaccharides, vitamin C, vitamin E, etc. Its natural efficacy is difficult to match with artificial medicine. Citizens who eat more purslane will have a corresponding brain-boosting effect. Purslane, commonly known as longevity vegetable, is a common herb. Many citizens like to put purslane on the table as a delicacy.

As a medicinal purslane, it has a good effect on heat-toxic bloody dysentery, antibacterial and anti-inflammatory, and diarrhea, and has been widely used in clinical practice. The expert group of Wuhan Science and Technology Bureau appraised that the scientific research results of "Mechanism of Action of Portulaca Oleracea Aqueous Extract in Resisting D-galactose-Induced Brain Neurotoxic Damage" of Wuhan No. 1 Hospital have reached the international advanced level, which provides a valuable scientific basis for the research and development of new drugs to delay aging and prevent and treat Alzheimer's disease.
