I really like lavender oil, it really help me relax.  I find that it is very calming and I really like the scent at well.  I use it in a diffuser, place drops of oil in a warm bath and my favorite way is to use it on my bedding.  I add a few drops to a spray bottle and spray my bedding and pillow with water a little bit before I go to sleep.  If you suffer from anxiety you can place a drop or two directly on your skin on in a necklace made for essential oil.   I have tried the necklaces, and I found that the scent tends to make me sleepy.  I have tried several kinds of lavender essential oils and this is  lavender oil by New York Biology is one of the better ones.  The scent smell just like lavender.  It comes in an amber colored bottle, the dark colored bottle keeps the oils better longer.  I received this item in exchange for my honest, unbiased review.
