                          What is rhubarb extract used for?

                          1. Rhubarb extract has a neuroprotective effect. It can reduce the release of inflammatory factors, thereby reducing brain tissue damage.
                            In addition, rhubarb has a potential therapeutic effect on neurodegenerative diseases. It can also reduce cell apoptosis, reduce neuroinflammation and oxidative stress, and thus play a neuroprotective role.
                          2. Improve the intestine. Specifically, rhubarb extract can not only enhance the diversity of intestinal flora, reduce the abundance of harmful bacteria, but also improve metabolic disorders.
                          3. The procoagulant effect of rhubarb extract. Rhubarb and rhubarb phenol have the function of reducing wound exudation, shortening coagulation time, and promoting platelet production.
                          4. Lowering blood lipids. The anthraquinone components contained in rhubarb have the effect of regulating lipid metabolism and reducing high cholesterol.
                          5. What's more, the anthraquinone compounds in rhubarb extract have good antibacterial and anti-inflammatory effects.
