Antimony pill (everlasting pill)

Characteristics and mechanism

The pills were made from elemental antimony (symbol Sb) or alloys containing the element. In the acidic environment of the stomach some surface corrosion and the formation of soluble antimony salts was believed to produce the emetic and laxative action. Contemporary practitioners described a predictable purging effect after ingestion. From a modern toxicological standpoint, antimony and many of its soluble compounds are biologically active and can be harmful; the historical therapeutic effect likely came from small amounts of soluble antimony species produced in gastric fluid.

Historical use and context

Antimony pills appear in European and North American medical practice from the early modern period through the nineteenth century, when purging remained a common therapy for a wide range of ailments. They were part of a larger family of antimonial remedies that also included antimony cups and solutions of antimony salts (so‑called "tartar emetic"). The pill appealed to users and itinerant physicians because a single object could be reused many times, reducing cost and waste in an era before standardized pharmaceuticals.

Uses, examples and social aspects

Doctors prescribed antimony pills to cleanse or "revive" the bowels according to humoral medical ideas of the time. Because pills were recoverable, families sometimes kept them as household remedies. Medical manuals and travelers' accounts of the nineteenth century mention their use during journeys and in rural areas where access to a physician or fresh medicines was limited. Collectors and museums now sometimes hold examples as artifacts of historical medicine.

Risks and later abandonment

Over the nineteenth and twentieth centuries the risks of antimony exposure became better understood and safer, more effective medicines were developed. Soluble antimony compounds can cause nausea, vomiting, abdominal pain and systemic toxicity; for that reason antimony pills fell out of medical favor and were abandoned in mainstream practice. Today, antimony is handled as a toxic industrial element, and its use as a routine medicinal purgative is considered obsolete.

Notable distinctions and references

• Not the same as an "antimonial cup," which was a vessel used to leach antimony compounds into wine or water to produce an emetic.
• Historically tied to older paradigms of cleansing and purging rather than modern pharmacology.
