From Aromedica I buy gorgeous aromatherapy oils. You can pick and choose whatever you would like.
To cover the whole body in oil is wonderful before bedtime. The oils really get to work while you sleep, and if you are lucky you might release some tension.
I do find that some days my stretch in some asanas are more flexible than if I don´t use it. Try it and see if it is for you. Just the gorgeous smell is worth it.
