Everyone should have a bottle of Lavender(Lavandula angustifolia) Essential oil in their first aid kit, or in my case the kitchen.
It is amazing for burns - The pioneer or aromatherapy had an explosion in his lab and burned his hand really badly (back when an injury like that would end up killing you) and not having anything else around he stuck his hand in a vat of Lavender and it healed right up with barely a scar. Was also used extensively in te World War battle med kits when drugs were scarce.
Personally, I use it all the time. I'm always grabbing the hot handle of a cast iron pot not thinking first. Also a few weeks ago I was searing a pork roast in some oil and it popped and got onto my face in at least a dozen spots(luckily I had my glasses on) I went to the bathroom, washed and put on Lavender and came right out, no one noticed I had even been burned. No itching, no scarring and it takes the pain away quite quickly. We also have it on hand because hubby tends to get scratches playing with the dog all the time. It is both an antiseptic and analgesic.
