Rutin, a flavonoid found in various plants, has been extensively studied for its diverse pharmacological effects. This review highlights rutin's therapeutic potential in various physiological systems, including the central nervous system, endocrine system, cardiovascular system, gastrointestinal system, respiratory system, bones, eyes, excretory system, reproductive system, and anticancer activities. Rutin exhibits neuroprotective, anti-inflammatory, and antioxidant properties, and has been shown to prevent neuroinflammation, promote neural crest cell survival, and reduce oxidative stress. It also demonstrates antidiabetic, anti-hypercholesterolemic, and thyroid uptake-promoting effects. In the cardiovascular system, rutin has antihypertensive, antiplatelet, and cardioprotective properties. It also shows antiulcer, antiasthmatic, and anti-inflammatory effects in the gastrointestinal and respiratory systems. Rutin has antiosteoporotic and antiosteopenic effects on bones, and exhibits anticataract and ophthalmic effects on the eyes. It has diuretic effects on the excretory system and protective effects on the reproductive system. Rutin also demonstrates anticancer, chemotherapeutic, antibacterial, antifungal, antimycobacterial, larvicidal, antimalarial, antiretroviral, and antiviral activities. Additionally, rutin has protective effects on the liver, kidneys, and blood vasculature. It also promotes wound healing and has radioprotective effects. Rutin is generally considered safe, with no significant toxic effects, and has a favorable structure-activity relationship. Overall, rutin is a promising phytochemical with a wide range of therapeutic applications.Rutin, a flavonoid found in various plants, has been extensively studied for its diverse pharmacological effects.
