Camphor essential oil is extracted from the camphor tree, a tree native to Asia. It has a powerful, fresh and minty aroma. This essential oil is renowned for its invigorating, decongestant and analgesic properties. It is often used in aromatherapy to relieve muscle and joint pain, clear the airways and stimulate blood circulation. Camphor essential oil should be used with care and diluted properly, as it can be irritating to skin and mucous membranes.
