What is the best otc medication for tension headaches. none with caffeine, please.

See that you: have severe generalized anxiety disorder with tension headaches. So - decreasing anxiety would be a good start. Passion Flower, Lemon Balm, Humulus lupulus (Hops) Valerian & Chamomile may help. Although Kava Kava may help, it has potential to cause liver damage. Lavender & chamomile essential oils (not ingested) are also calming. Discuss use of any of these w/ your physician before use.
