The neem tree's antibacterial, antiparasitic, and antifungal properties make it the perfect base for soap. Neem soap is made from neem oil and is recommended for those with skin problems including eczema, psoriasis, scabies, and acne. The percentage of neem oil in the soap is important in determining the quality of the soap. Medicinal soaps should contain around 20 per cent neem oil or more. The method of processing the oil is also important because, like any oil, neem oil changes when exposed to heat. Organic, cold-pressed neem oil soap is the highest quality neem soap on the market. Most of these soaps also contain essential oils such as lavender in order to cover the strong smell of neem. The smell of neem indicates that the soap does indeed contain a high percentage of neem oil, and it is normal. Neem soap is a natural solution to many skin conditions, and eBay has a variety of neem products from reliable sellers, making it easy for you to treat your skin to the best that Nature has to offer.
