Oudh oil, also known as Agarwood oil, is an essential oil extracted from the heartwood of the Aquilaria tree. It is known for its complex and intense woody, musky, and sometimes sweet aroma, which is highly prized in perfumery and traditional medicine. Oudh oil is said to have a grounding and calming effect on the mind and is used in perfumes, incense, and traditional medicine. It is also believed to have anti-inflammatory, antimicrobial, and antioxidant properties, which may make it useful for treating certain skin conditions. Oudh oil is typically used in aromatherapy, perfumery, and traditional medicine. It is considered safe for most people when used topically in small amounts, but it's always best to do a patch test before using it and to consult with a healthcare professional before using it internally.
