NeemFor centuries, the neem tree has been used in India to treat a variety of ailments. It possesses anti-inflammatory, anti-fungal and anti-viral properties. Used in soap form, neem can work wonders in clearing up acne. Neem treats acne in two ways. First, it kills the bacteria that can lead to acne. Second, it reduces the inflammation and redness of outbreaks.
According to the Neem Foundation, washing with neem soap is safer and gentler than using "synthetic chemicals that often produce side effects such as allergic reactions, rashes, etc. Neem is gentle and does not create any complications."
