Margaret, one of my students, examines the lemongrass plant, source of lemongrass essential oil, which is useful in treating stress-related conditions (it's also an insect repellant).
This was a particularly fun class because it was small enough for us to do some real hand-on samplings of herbs and essential oils. One of the things I stress in my aromatherapy classes is that it's about plants more than just fragrances.

Only about 200 plants are commonly used for the production of essential oils used in aromatherapy - here we sample some of them.
