What is Antimonium arsenicosum?

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).

How does Antimonium arsenicosum work?

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.

What forms does Antimonium arsenicosum come in?

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.

Where it comes from:

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.

What does Antimonium arsenicosum help with?

• Long-term wheezing and breathlessness: This is the classic homeopathic picture for the remedy. Old books describe a person who is worse lying down and worse in damp air. No human trials test the remedy for this. Sudden or severe breathing trouble needs real medical care, not pellets.
• Emphysema and COPD (a long-term lung disease): Homeopaths have long paired this remedy with long-term lung damage and a hard, tiring cough. There are no published trials in people. COPD care needs inhalers, check-ups and often oxygen, and none of that should be swapped for a remedy.
• Chesty cough with a lot of phlegm: Books list a loose, rattling cough with thick mucus that is hard to bring up. No trial evidence supports this use. A cough with fever, blood or green phlegm should be checked by a doctor.
• Swelling of the legs or belly linked to a weak heart: Older texts mention dropsy, an old word for fluid build-up in the body. There is no trial evidence here at all. New or growing swelling can be a sign of heart or kidney trouble and needs a prompt check.
• Pleurisy (pain and fluid around the lungs): Traditional texts link the remedy to sharp chest pain with fluid around the lung. No human studies exist. This condition needs a doctor, because the cause may be infection or a blood clot.
• Dry, scaly skin rashes: A dry, itchy eczema-like rash appears in the old remedy picture. No trials have tested it. Standard skin creams and a doctor's advice have far better support.

Which foods are rich in Antimonium arsenicosum?

1. Rice and rice cereal: rice takes up arsenic from soil and water
2. Seaweed: can hold arsenic from sea water
3. Shellfish and some fish: a common source of arsenic in the diet
4. Well water in some areas: may carry arsenic from rock

Practical Tips:

These foods matter only because arsenic is the source metal here; they are not a way to take the remedy.

What are the side effects of Antimonium arsenicosum?

• No effects at all, which is the usual outcome at 30C
• Upset stomach or loose stools in people who react to lactose (milk sugar)
• Rash or itching if you react to the pellet base
• A short flare of your symptoms, which homeopaths call an aggravation
• Delay in getting real treatment, which is the main risk
• Signs of arsenic or antimony harm from very low strengths: stomach pain, vomiting, numb or tingling hands and feet, dark skin patches

Good to know:

At 30C the pellets are sugar, so direct harm is very unlikely. Reactions are rare and mild when they do happen.

The two real risks sit elsewhere. One is using it in place of care that works. The other is taking a very low strength that still holds arsenic and antimony.

How much Antimonium arsenicosum should you take?

• Recommended daily: No dose has been set by research. Nothing here is a proven amount. In practice, homeopaths suggest 30C pellets. A common pattern is 3 to 5 pellets, two or three times a day. Strengths below 6X or 4C should be avoided. They can still hold real arsenic and antimony.
• Best time of day: Any time of day. Many people take it on waking and again at bedtime.
• With or without food: Usual advice is to take it on an empty mouth. Leave about 15 minutes either side of food, drink, coffee or toothpaste. There is no evidence this matters.
• Time to effect: No reliable time frame exists, since the remedy has not beaten placebo in trials. Homeopaths say to look for change within a few days.
• How long to take it: Homeopaths usually suggest a short trial of a few days to two weeks. Then you stop and look at what changed. Stop sooner if you feel worse. See a doctor if your breathing or cough has not improved in a week.
