Skin
Lavender is great for minor skin conditions like small cuts, burns and bug bites.
Allergies
Putting lavender on the back of the neck or taking it in a capsule with lemon and peppermint is effective for allergy relief.
Relaxation/Sleep
Lavender is extremely calming. Putting several drops in a diffuser is a great way to breathe it in and help you calm down. You can put it on your neck and wrists as well.
My favorite use of lavender is rubbing a drop on each foot at bedtime. I get deep sleep every night I do it, and it helps me fall asleep faster.
Diffuse it in your bedroom or your children's bedroom at nighttime to aid in sleep, as well.
