Nux vomica taken as a constitutional remedy, improved a man's asthma until he was given Phosphorus 200c for influenza. Asthma returned a few weeks later. There was discussion on the use of an acute remedy or a chronic (constitutional) remedy. Dr H A Roberts declared that the similimum should be prescribed at the time, ie the acute remedy in this case. The acute remedy could be a lower potency of a remedy complementary to the constitutional remedy.

The relationship between sycosis and asthma has been repeatedly stressed. Suppression of chronic skin eruptions has been followed by asthma. Conversely, under homoeopathic treatment amelioration of asthma has been followed by skin eruptions especially eczema and urticarias. The three remedies Medorrhinum, Natrum sulphuricum and Silicea are most useful in treatment of asthma in children. Homarus, Mephitis and Blatta orientalis were also suggested in the discussion.
