Last night I burned myself cooking dinner. After I ran my hand under cold water for a few minutes, I rubbed some lavender oil on the burn. It instantly felt better and, from past experience, I know it's not going to leave a scar. A massage therapist gave me this tip a few years ago and I've kept it in the kitchen ever since.
Besides the calming effects and relief from burns, there are a number of other health benefits of lavender oil. Check out http://www.netherfield.co.nz/lavender-uses.php for more uses of lavender oil.
