The author states that asthma is not an easy disease to treat but in some cases cure is possible. He relates the case of a 44-year old man who has had recurrent attacks of asthma for twenty years since suffering from a severe attack of bronchitis. His totality of symptoms was taken and Arsenicum album was prescribed but without success. Natrum sulphuricum was then administered in ascending potencies over ten months with anti-sycotic Thuja occidentalis as an intercurrent remedy. This treatment resulted in less frequent but equally severe attacks of asthma. Lycopodium clavatum with Thuja intercurrently over 9 months finally cured the patient's symptoms.
