If you’re looking to add an herbal dimension to your basic first aid kit, let me introduce the Bite & Burn Spray. Mild burns and insect bites can be given a quick spritz to aid in pain and faster recovery of your skin. 
 
Witch hazel contains tannins which help the skin to tighten and therefore reduce swelling and pain and promote faster healing of broken skin. Witch hazel also acts as a antimicrobial, sending opportunistic bacteria on their way.
Fat and the Moon's yarrow hydrosol bring the first aid properties of the plant. Along with being astringent and anti microbial, yarrow aids the skin in minimizing scarring and inflammation. 
Lavender and tea tree essential oil also act as antimicrobials as well as anti-inflammatories and antiseptics.

Side note: for all burns, don’t apply any kind of ointment when you are first burned as it will trap in the ‘heat’ and your burn can get more serious. Give a good Bite & Burn spritz to the area and let dry, after a day you can apply ointment to mend your skin.
