The orange tree, native to China and India, was introduced to Europe by Portuguese sailors in the 12th century and was a rare commodity until the late 17th century. Orange essential oil offers skincare benefits by providing nutrients that help the skin recover from environmental damage and dehydration, aiding in Vitamin C absorption to combat oily skin and blemishes. In Ayurvedic therapy, it helps alleviate cold and flu symptoms and manage irritability and anxiety.
