Unconventional therapies in asthma: an overview

Acupuncture, homoeopathy, mind-body therapies, and nutritional, herbal, and environmental medicine have all been used in the management of patients with asthma. This paper reviews the evidence base for the use of these unconventional or complementary therapies. Although there is a paucity of large randomized, controlled trials in this area, there is sufficient evidence to suggest that many of these therapies can produce objective and subjective benefit in selected groups of patients. In view of the increasing popularity of complementary medicine among patients and general practitioners, there is now an urgent need for high-quality research to determine how, or whether, these therapies may be interwoven with the more orthodox treatments currently available.
