The British Guideline on the Management of Asthma 2008 grants permission for British health professionals to recommend Buteyko, stating that the method "may be considered to help patients control the symptoms of asthma". The guideline also grades clinical research on Buteyko with a 'B' classification - indicating that high-quality supporting clinical trials are available. No other complementary therapy has been endorsed by this body for the treatment of asthma.
