Neem (Azadirachta indica) is a versatile botanical with a long history in traditional medicine, and modern research has begun to explore its wide-ranging properties. Studies indicate that neem leaf extract and neem oil contain bioactive compounds, particularly azadirachtin and nimbidin, that demonstrate antimicrobial, anti-inflammatory, and antioxidant activity in laboratory and preliminary clinical settings. Research suggests potential benefits for skin health, including acne management, as well as supportive roles in oral hygiene, blood sugar regulation, and immune function, though many of these findings are still in early stages and larger human trials are needed. Available commonly as a leaf extract supplement or as a topical oil, neem continues to attract scientific interest as researchers work to better understand its mechanisms and long-term safety profile.
