I get a lot of emails saying, eg, "I have Hep C and my dad has Lupus and Crohn's, and my mon's hypothyroidal, what herbs can you recommend for that?" - I don't recommend herbs for that at all, I give a list of referral sites and addresses for alternative healthcare associations. Here it is, gathered over a couple of years:
Try the American Association of Naturopathic Physicians (AANP): http://www.naturopathic.org
Or the American Herbalists Guild (AHG): http://www.americanherbalistsguild.com
Brits can look for member of the National Institute of Herbal Medicine (NIMH): http://www.nimh.org.uk
Australians have the National Herbalists Association of Australia (NHAA): http://www.nhaa.org.au
If you're in New Zealand check the New Zealand Association of Medical Herbalists (NZAMH): http://nzamh.org.nz
If you still can't find a practitioner near you, you can try the bulletin boards at your local coop / health food store / vegetarian restaurant / other similar place.
