If you know what sort of therapist you are looking for, half the battle is over. It is more difficult if you have an interest and would like to experiment. As always, it is easier to experiment in the bigger cities and wandering around the city you may come across anything from a Chinese herbalist to a Rosen method therapist.
Word of mouth is a fairly reliable source of information although alternative medicine and therapy is often a personal choice. Talking to people around you might at least help in finding out what your choices are.
Health food shops tend to be good places for local therapists to advertise and the people who staff them are usually in the know about who is around.
Failing that, there are some good websites that will help you find both a method and a therapist that suit. Their information on the Swedish websites is predominantly in Swedish so research on the actual method is best done first in English.
