I am not, like, a witch or a dirty hippie, but I use essential oils. They smell nice, they calm me down, and unlike perfume they don't seem to assault the nostrils of people around me. Here's how you too can use essential oils in cool, sophisticated, only slightly witchy ways.
Use peppermint essential oil to get rid of headaches.
Peppermint essential oil was my gateway essential oil, because it is actually extremely useful! Peppermint contains large quantities of menthol, a strong analgesic, and applied topically it's great for temporarily getting rid of headaches. As a migraine sufferer, I always carry this one around.
Peppermint essential oil is really strong, so you'll need something to dilute it before applying it to your skin—I usually use regular body lotion, but you can even use oil. Coconut oil and almond oil smell great and are trendy, but if you just have olive oil around, that works too. Add one or two drops of peppermint essential oil to your lotion or oil and apply the mixture to your forehead and the back of your neck; you'll feel a pleasant, cool, tingly feeling.
