Asthmador was a nonpresciption treatment for the relief of bronchial asthma made by the R. Schiffmann Company. It consisted of a mixture of belladonna, stramonium and potassium perchlorate, and was a fine powder intended to be burnt and the smoke inhaled. The primary alkaloid present in the mixture was hyoscyamine, and when the powder was ingested rather than burnt, could be used to induce hallucinations. In severe overdose it could hospitalize the patient or cause death.
Prior to the introduction of rescue inhalers in the mid-1950s this was an effective over-the-counter remedy for asthma attacks. Asthmador was sold in packets like cigarettes, in tins like pipe tobacco, or as an incense. The paroxysms would abate after a few minutes of the victim inhaling the mixture.
