This article follows the ideas of Bernoville, Vannier etc in France. It is stated that an asthmatic is an intoxicated subject, who seeks, by means of a violent and spasmodic crisis, to elimiated the toxins which oppress him. These crises are met with in some patients whose nervous systems are in a state of exaggerated excitability. Treatment of asthma must be chronic, and will be 1) Symptomatic 2) Constitutional 3) Causal. Symptomatic treatment will relieve but will not cure and then more deeply-acting remedies must be used after the attack. Constitutional treatment needs patients to be divided into three types - oxygenoids, hydrogenoids and carbo-nitrogenoids. Remedies are given for each type. Causal treatment may require Lueticum, Tuberculinum, Medorrhinum, Psorinum and autotherapy. Other factors such as diet, climate or surgery could be considered also.
