Aromatherapy - do you believe it really works and why  

I believe in the power of aromatherapy, especially when coupled with music, yoga and/or other forms of meditation and relaxation techniques. There is nothing better than a hot bath filled with lavender petals when your muscles and your brain are tired and aching. What types of aromatherapy has everyone used and liked? If you don't believe in it at all why not and what have been your experiences?
