One of neem’s stronger advantages is its effect upon the skin in general. It has been most helpful in treating a variety of skin problems and diseases including psoriasis, eczema and other persistent conditions.

According to a report from the National Research Council’s Ad Hoc Panel of the Board on Science and Technology for International Development, Neem preparations from the leaves or oils can be used as general antiseptics. Because neem contains antibacterial properties, it is highly effective in treating epidermal conditions such as acne, psoriasis and eczema. It is also used for treating septic sores, infected burns, scrofula, indolent ulcers and ringworm. Stubborn warts can be cleared up when a high-quality neem product is used. Unlike synthetic chemicals that often produce side effects such as rashes, allergic reactions, or redness, neem doesn’t seem to create any of these results.

Early Ayurvedic practitioners believed high sugar levels in the body caused skin disease. Neem’s bitter quality was considered to counteract the sweetness. Indians historically bathed in neem leaves steeped in hot water. This is still considered a common procedure for curing skin ailments or allergic reactions.
