Arsenicum album, commonly known as white arsenic or arsenic trioxide, is a chemical compound with the formula As2O3. It is a colorless, odorless, and tasteless powder that is highly toxic in its inorganic form. In homeopathy, Arsenicum album is used as a remedy, often abbreviated as Ars. alb., and is prepared through a process of dilution and succussion. The name translates to ארסניקום אלבום in Hebrew, Arsenico album in Italian, Arsénico album in Spanish, and Arsenicum album in German and French. Historically, it has been used in both traditional and alternative medicine, though its use is controversial due to its toxicity. In homeopathic practice, it is believed to treat a range of symptoms, including anxiety, restlessness, and digestive issues, though scientific evidence supporting its efficacy is limited.
