Arsenotherapy refers to the use of arsenic-based drugs for treating various medical conditions. However, due to the potential toxicity of arsenic, several alternative terms have been proposed. One such term is "arsenic treatment," which is a broader term encompassing the use of arsenic for non-medical purposes such as pesticides, herbicides, and rat poison. "Arsenical therapy" is another synonym that is often used interchangeably with arsenotherapy. However, it is important to note that both terms refer specifically to the medical use of arsenic-based drugs. Other synonyms for arsenotherapy include "arsenical treatment," "arsenic chemotherapy," and "arsenic-based treatment".
