you can add chamomile and lavender essential oil to St John Wort's Oil, and apply to skin.
St John Wort's Oil is a kind of natural oil which is very good for problem skin or burn skin. Long time ago, there is a real story that a doctor use this oil to treat a little boy who burn his skin.
Sometimes I got burn during cooking or by touching the hot burning wok, I will apply this immediately.
The lavender and chamomile is a very good combination to calm and soothe the skin.
