Neem oil has incredible health and beauty benefits and has antibacterial, antifungal, and antiviral properties which can help relieve many skin conditions, including: eczema, fungus (it can prevent and neutralize fungus on nails and feet), acne (since it contains a compound similar to aspirin which can remove the bacteria which causes that, and has fatty acids which can help prevent acne scarring), or head lice. It can even fight the visible signs of aging, since it contains carotenoids which act as antioxidants to protect the skin from damaging free radicals.
