Piercing, fresh and wonderfully head-clearing, eucalyptus is one of those oils every home ends up wanting. Tisserand's version is distilled from organically grown leaves in Spain and certified by the Soil Association, and this generous 20ml bottle offers roughly twice the usual size for regular users.

The bottle contains 100% organic eucalyptus leaf oil with its strong, camphoraceous, balsamic aroma. It is a classic choice for the diffuser during the colder months and after long days: add six to eight drops to a vaporiser, or blend five drops into 10ml of carrier oil for an invigorating massage. It combines well with grapefruit, peppermint and rosemary. For external use only, never applied neat to the skin, and best stored in a cool, dark place with the cap tightly closed once opened.
