Reprinted from the 'Homoeopathic Recorder' of 1890 and 1891. Blatta orientalis (Indian cockroach) was first discovered to be of use in asthma treatment when a drink of tea cured an asthmatic. A dead cockroach was found in the teapot. The author used Blatta orientalis in almost all cases of asthma and received good results in most cases. A low potency should be given during an asthma attack, but when the spasm subsides the cough and wheezing is better relieved with a high potency. Continuation of the low potency caused streaks of blood in the sputum. Four case reports are given. In one case a 55 year old man, apparently terminally ill with fever and asthma, recovered with Blatta orientalis 1x.
