Herbs contain small glands that hold their essential oils, and when these oils are extracted they release scent molecules. The science of aromatherapy takes advantage of this natural phenomenon and expands it just a bit -- because olfactory sensation stimulates parts of the brain connected to memory and emotion.
This is a fun - and simple - idea that was inspired by a blogger who makes do-it-yourself solid perfumes to give away as gifts. Many people are into aromatherapy, and we all know that certain smells make us feel good. Use an empty locket to create a portable aromatherapy spa you - or a friend - can carry around all the time.
