As for chiropractic -- I wouldn't go near one. I would go to an osteopath without hesitation; their training is fully as rigorous as that of an MD and in some cases, such as anatomy, more so.

Homeopathy: no. Naturopathy: no. Aroma therapy, no. Much, but by no means all, herbal therapy: no.

What I try to do is to practice good hygiene, a balanced diet and life, and laugh a lot. When I do become ill, I go to a pro.
