The Romans used lavender in their bath water (its name derives from Latin -lavare, to wash)
Lavender oil, applied externally, may provide relief from headaches, eases the soreness of muscles and joints and reduces inflammation.
Sharon, our mom, uses lavender essential oil for relief of her mild arthritis. Diane, our graphic artist, uses a touch of lavender essential oil on her temples to relieve tension headache. And when my son was young , a bit of lavender flowers under his pillow would send him quickly to sleep.
