Curry leaves originate from the curry tree and are used to flavor South Asian cuisine. With a distinctive smoky, citrusy aroma and flavor, curry leaves may offer various health benefits according to Ayurvedic medicine. Research suggests curry leaves can lower blood pressure, have antibacterial and antiviral properties, and are rich in antioxidants. These antioxidants may moisturize the scalp and remove dead follicles. Furthermore, the beta-carotene and protein in curry leaves could prevent hair loss and thinning. Applying curry leaves to the scalp may also treat dandruff and promote hair growth. For the skin, curry leaves can soothe and cool acne-prone areas. Regular use may also diminish acne scars.
