Neem’s beneficial effects on skin make it one of the better treatments for eczema (atopic dermatitis). Neem moisturizes and protects the skin while helping to heal irritations. Add several tablespoons of Neem oil to a warm bath and soak for 20 minutes. Bathe or shower with Neem soap and shampoo. Apply Neem oil, or a Neem lotion several times a day to affected areas. Consider a Neem leaf extract or capsule to help boost the immune system.
