The author has prescribed DSCG to asthmatic children since September 1968. These children are hospitalised in a sanatorium 30 m above sea level in a well-wooded region with room for 180 children (boys and girls). There ages range from 3 to 18 years. About 100 of the 180 children were admitted to the sanatorium because of asthma or other allergic symptoms. At present 75 of these children are treated with DSCG. 35 of them were discharged from hospital treatment after a prolonged hospitalisation, but remain in ambulatory treatment and regular control. On the average there are given 3 capsules of DSCG per day, in a few cases up to 6 capsules a day. For a certain time placebos were given without being known by patients and staff. The criteria for the application of DSCG and the regular control measures of the children under treatment are described in details. In addition to DSCG the traditional methods of treatment are as well continued. The results show that mainly the bronchospatic factor is favourably influenced. The author draws attention to a few conditions complicating the evaluation of the results.
