What is Calcarea arsenicosa?

Calcarea arsenicosa is a homeopathic remedy. It is made from calcium arsenate, a white powder that holds arsenic. Homeopaths give it for tiredness, puffy swelling, hot flushes and worry.

The remedy is made by diluting the source again and again. At 30C, the usual strength, none of the starting material is left. What you take is water, alcohol or a sugar pellet.

Trials do not show any effect beyond placebo. The remedy has been used in homeopathy since the 1800s, but long use is not proof that something works. This page reports both axes: the evidence grade and the traditional tier.

How does Calcarea arsenicosa work?

There is no known way this remedy could act in the body.

Homeopathy rests on the idea of "like cures like". A substance that causes symptoms in a healthy person is said to ease those same symptoms when it is made very weak.

Makers shake the liquid hard at each step. They say this leaves an imprint of the source. Chemistry and physics do not support that idea.

At 30C, no molecule of the source is left. So any change you notice is likely a placebo effect. That is a real feeling, but it comes from hope and attention, not from the pill.

What forms does Calcarea arsenicosa come in?

You will most often see small white sugar pellets. Liquid drops in water and alcohol are also sold.

Strengths carry a number and a letter. "C" means each step mixes 1 part in 100. "X" means 1 part in 10.

Common labels are 6C, 30C and 200C. A higher number means more dilution steps, not more substance. Low labels such as 1X, 3X or 6X may still hold real arsenic.

Where it comes from:

Homeopathy began in Germany in the late 1700s with Samuel Hahnemann. His followers tested many minerals and metals in diluted form.

Calcarea arsenicosa appears in homeopathic reference books from the 1800s. It was studied by "provings", where healthy people took doses and wrote down what they felt.

It has never been a leading remedy. It sits in the second rank of homeopathic mineral remedies and is used mainly by trained homeopaths.

What does Calcarea arsenicosa help with?

• Long-lasting tiredness and weakness: Homeopathic books list this remedy for people who feel worn out and weak, often after an illness. No human trial has tested it for tiredness. If you are tired for weeks, ask a doctor to check for causes such as low iron, thyroid trouble or depression.
• Puffy swelling of the face, eyelids or ankles: Old homeopathic texts link this remedy to puffy swelling, often worse in the morning. There is no trial evidence for this use. Swelling can be a sign of heart or kidney trouble, so get it checked rather than treated at home.
• Hot flushes and low mood around menopause: Homeopaths have used this remedy for flushes, sweating and gloom around the change of life. No study has tested this remedy for these symptoms. Proven options exist, so it is worth talking to a doctor.
• Anxiety with restlessness at night: Tradition describes a picture of fear, fidgeting and waking in the small hours. This picture comes from provings, not from trials. Talking therapy and sleep habits have much better support.
• Burning, itchy skin rashes: Homeopathic texts mention dry, burning skin that feels better with warmth. No published trial supports this. A rash that spreads, weeps or hurts needs a real diagnosis.
• Night-time breathlessness: Some homeopathic books list this remedy for breathing trouble that wakes people at night. There is no trial evidence. Night breathlessness can come from asthma or heart failure, and both need medical care.

Which foods are rich in Calcarea arsenicosa?

1. Rice and rice products: rice takes up small amounts of arsenic from soil and water
2. Seafood: holds arsenic in a form that is mostly harmless to people
3. Well water in some areas: can hold arsenic and should be tested

Practical Tips:

These foods are not sources of the remedy. They simply add to the arsenic your body already meets.

What are the side effects of Calcarea arsenicosa?

• At 30C and above: nothing expected, since no source material is left
• Some users report a brief flare of their symptoms, which homeopaths call an aggravation; this is not proven
• Mild headache or upset stomach, rarely reported
• With low strengths that still hold arsenic: nausea, vomiting, belly pain or diarrhoea
• With repeated arsenic exposure: skin changes, numb or tingling hands and feet, and a higher risk of cancer
• The sugar pellets can upset people who cannot handle lactose or galactose (milk sugars)
• Delay in getting real treatment, which is the biggest risk of all

Good to know:

At 30C there is no source material in the pill, so direct harm is very unlikely. The real concerns are low strengths that may still hold arsenic, and using this instead of care that works. Tell your doctor about anything you take.

How much Calcarea arsenicosa should you take?

• Recommended daily: No dose has been shown to work in trials, so no daily amount can be recommended here. Labels on shop-bought tubes usually suggest 3 to 5 pellets under the tongue, two or three times a day. Homeopaths often give a single dose and then wait. Stay with 30C or higher if you use it at all. Low strengths such as 1X, 3X or 6X may still hold arsenic.
• Best time of day: Homeopaths usually suggest taking it away from meals, drinks, coffee and toothpaste, often on waking or at bedtime. There is no evidence that timing changes anything.
• With or without food: Taken without food. The usual advice is to leave about 15 minutes either side of eating or drinking.
• Time to effect: No reliable timing can be given. In good trials, homeopathic pills do not work better than dummy pills. Any change people notice usually turns up within a few days and is likely placebo.
• How long to take it: Keep any trial short. A few days is enough to see that nothing is changing. Stop after two weeks at most. If your symptom is still there, book a doctor's appointment instead. Never use it for months on end, and never in place of a treatment your doctor has given you.
