Neem leaves come from the Neem tree, which has been used for centuries in traditional medicine, particularly in South Asia. Modern research suggests neem contains compounds with antimicrobial, anti-inflammatory, and antioxidant properties. However, many traditional uses have not been confirmed by high-quality clinical studies.

Here are some of the potential health benefits and what the evidence says:

• May help fight bacteria and fungi: Laboratory studies show neem leaf extracts can inhibit the growth of certain bacteria and fungi. This is one reason neem is commonly used in soaps, toothpaste, and skin products.
• Supports oral health: Neem twigs and leaf extracts have been studied for reducing dental plaque and gum inflammation. Neem-containing mouthwashes may help improve oral hygiene when used alongside regular brushing and flossing.
• May reduce inflammation: Some compounds in neem leaves appear to have anti-inflammatory effects in laboratory and animal studies, but more human research is needed.
• Rich in antioxidants: Neem leaves contain plant compounds such as flavonoids and polyphenols, which help protect cells from oxidative stress.
• May support skin health: Neem is commonly used topically for acne, eczema, dandruff, and minor skin infections because of its antimicrobial and anti-inflammatory properties. Evidence is mixed, and it should not replace prescribed treatments for serious skin conditions.
• Blood sugar research: Some animal studies and a small number of human studies suggest neem may help lower blood sugar, but the evidence is not strong enough to recommend it as a treatment for diabetes.

Caribbean use:

• Fresh leaves in small amounts in traditional cooking.
• Dried leaves brewed as tea (though scientific evidence for health benefits is limited).
• Ground leaves used in face masks or hair treatments.
• Neem extracts in oral care and skincare products.
