Stay healthy on holiday

Lavender oil

This essential oil is a truly multipurpose travel companion. Use it as an air freshener - just flick the bottle around - and it'll also deter insects. Dilute (two drops in a glass of water) and dab on to any sunburn you've been foolish enough to get. It will help soothe you to sleep at your destination if your jetlagged body-clock is out of synch - inhale a few drops from a hanky or pillowcase.
