Basil essential oil is an oil extracted from the leaves of the basil plant, also known as Ocimum basilicum. It has a fresh, sweet, and slightly spicy aroma. It is known for its energizing and stimulating properties, and has been traditionally used to help with fatigue, mental clarity, and concentration. Basil oil is also believed to have antimicrobial properties, which may make it useful for treating certain skin conditions and also it is used in aromatherapy to help with respiratory issues such as colds, coughs and sinusitis. Basil oil is also used as a flavoring agent in food and beverages. 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, as large doses can cause skin irritation, and other adverse effects
