Some two years ago a patient of mine asked me whether we make any use of _Talápoka_ (cockroach) in our Pharmacopoeia. My reply was that we use many loathsome insects as our remedial agents. I told him also that _Blatta Americana_ (American cockroach), I had heard, had been used in cases of dropsy, but I had no practical experience with it. He then said the Indian cockroach is used in cases of asthma and he knew several cases had been cured with it. This struck me and I determined to try this in cases of asthma whenever next opportunity occurred. For this purpose I got a lot of live cockroaches, killed them and pounded to a fine pulp and triturated according to class IX of American Homoeopathic Pharmacopoeia, that is, two parts by weight of the substance and nine parts by weight of sugar of milk, giving 1x trituration. Thus I prepare up to 3x trituration and I also make an alcoholic solution--a few live cockroaches were crushed and five parts by weight of alcohol poured over them--it was allowed to remain eight days in a dark, cool place, being shaken twice daily. After the expiration of that period the alcoholic solution was poured off, strained and filtered, when it was ready for use. I began to try both the preparations--drop doses of the tincture and grain doses of 1x, 2x and sometimes 3x, 3 or 4 times daily when there was no fit and almost every fifteen minutes or half hourly during the severity of a fit. Both preparations began to answer well and I was getting daily more and more encouraged about the efficacy of this new drug. I had the opportunity of trying quite a number of cases of asthma within this short time, the reports of which I wish to publish in the future, but for the present I am glad to say in many cases it acted almost specifically, that is, the whole trouble cleared away within a fortnight or so without recurrence. In some cases the severity of the paroxysm was lessened and the recurrence of the fits took place at a longer interval; in others again only temporary benefit was observed. This failure to benefit all cases alike I attribute to many circumstances. Some people did not, rather could not, take the medicine regularly according to my directions owing to their untoward circumstances; some persons were suffering from other complications along with asthma; some again got temporary relief and in the meantime discontinued the medicine and came back again when there was a recurrence of the fits, that is, they did not continue the drug for sufficient length of time. Some cases again, not having derived immediate benefit, got impatient and discontinued the medicine without proper trial.
