A retrospective study was carried out on 120 children who had been treated with individualised homoeopathic treatment between the years 1985 and 1990 in order to assess its effectiveness in the treatment of bronchial asthma. Outcome was assessed according to four categories which were defined based on the period of time which elapsed between each crisis - "Satisfactory improvement", "Manifest improvement", "Relative improvement" and "No reaction". Remedies prescribed most frequently were Lycopodium clavatum, Sulphur, Pulsatilla and Silicea. Other medicines prescribed were Phosphorus, Nux vomica, Kalium carbonicum and Arsenicum album. Results showed that 44.2% of patients had a "satisfactory reaction", 36.7% a "manifest improvement", 18.3% a "relative improvement" and 0.8% showing "no reaction". It is concluded that homoeopathy is an effective intervention in the treatment of bronchial asthma which may contribute to a decreased number of hospitalizations, however a double-blind trial is worth pursuing.
