I often get asked which tea might work for various health related issues:

Rosemary Tea:  Seems to work well for Headaches

Valerian Tea: Works good for insomnia and anxiety

Peppermint, Chamomile and even Ginger Tea:  Eases stomach distress and helps with digestive issues

White Willow Bark Tea:  This tea seems to relieve pain in the same way aspirin would, but without the stomach irritation.
