Homoeopathy is widely used in the treatment of respiratory tract diseases. Close cooperation between homoeopathic practitioners and pulmonologists should be further increased in order to check the success of the treatment by means of pulmonary function tests. Only six controlled studies could be found in this field. One controlled study shows the superiority of a homoeopathic complex remedy over placebo in treating chronic cough. Four studies deal with a homoeopathic treatment of pollinosis, three of them show a significant efficiency of homoeopathically prepared Galphimia glauca and of a highly potentised pollen preparation. One double-blind randomised trial shows the efficiency of highly potentised antigene in treating atopic asthma. The studies published so far show only little relevance to the daily practice where a highly individualized remedy is usually used in the treatment of chronic diseases. A controlled multicentric study in cooperation between homoeopathic practictioners and pulmonologic clinics using individual prescription of the remedy is in preparation.
