Antimonium arsenicosum is a homeopathic remedy. It is made from antimony arsenate, a mineral that joins two metals. Homeopaths reach for it mainly for long-term chest and breathing complaints.
The starting mineral is ground up and mixed with water or alcohol. It is then diluted again and again, with hard shaking at each step. At the common 30C strength, none of the starting material is left in the pellet.
Tradition and proof are two different things, and this page reports both. The remedy has a small, steady place in homeopathic books. It has not been shown in trials to work better than a dummy pill (placebo).
There is no proven way this remedy could work in the body. At 30C there is nothing of the mineral left to act on you.
Homeopaths work from an old idea. They say a substance that causes symptoms in a well person can ease similar symptoms in a sick person. They also say the shaking leaves a trace or pattern in the liquid.
That idea has not been shown to hold up in the lab or in good trials. Any relief people feel is best explained by placebo, by time, or by other care they are getting.
The usual form is a small sugar pellet or pill. You let it melt under your tongue.
Liquid drops in alcohol and water are also sold. So are lactose (milk sugar) tablets.
Strengths are written as 6C, 30C, 200C or 6X. A higher number means more dilution steps and less chance of any source material. The 30C strength is the one most shops carry.
The remedy comes from homeopathy, which began in Germany around 1800. Antimony and arsenic salts were both used in medicine long before that.
It was written up in homeopathic materia medica (reference books of remedies) in the late 1800s. Writers such as Boericke listed it for hard breathing, wheezing and swelling.
It has always been a minor remedy. It is far less used than Arsenicum album or Antimonium tartaricum.
Some reactions to Antimonium arsenicosum need urgent care. Call your local emergency number or go to an emergency department straight away — do not wait to see whether it passes.
Call emergency services if you cannot speak a full sentence, your lips or fingers turn blue, or your chest pain is crushing.
See a doctor the same day for a fever with a cough, blood in your phlegm, or new swelling in your legs or belly.
See a doctor soon if your cough or breathing has not improved in a week. Also get checked if you took a low-strength product and feel sick, are vomiting, or notice numb or tingling hands and feet.
