A member of the mint family, thyme is closely related to oregano and has been used for thousands of years for medicinal and culinary applications. It's also great for your skin. Try thyme tinctures as a remedy for acne (this study indicates that it may work better than acne treatments with benzoyl peroxide). It can also help alleviate sunburns or rashes. Chock-full of antioxidants, thyme oil can also impede the ageing process and aid in achieving glowing, healthy skin.
