My personal favourite uses for basil is applying it around my belly button when I'm having troubles digesting or when I get cramps from my period. Basil helps ease my cramps and also acts as a perfume (A very strong perfume might I add. Whenever I apply basil, my boyfriend always says "you need to warn me before you put basil on. I can smell it from across the room!"). Basil also tastes great in salads and is awesome for an added 'umph' when making soups.

And while basil may not be in the everyday oils kit, it is one of the oils in the raindrop technique kit which has some amazing oils in it that help with germs, colds, digestion and more. The link will take you to the young living website for the raindrop technique collection. I can see myself getting that kit in the near future... or just get the individual oils so I have 15ml bottles of them all! Who knows!
