Alternative medicine, it's official

NOT long ago, orthodox doctors shunned them as quacks. Now the medical profession has begun to ask whether alternative practitioners may have something useful after all. That is common enough anywhere. But Vancouver Hospital, Canada's second-largest, has gone further, making the partnership official. Its new Tzu Chi Institute for Complementary and Alternative Medicine aims to sort out scientifically the useful from the useless in the welter of non-conventional therapies, and to integrate what works into conventional practice.
