What is Strontium carbonicum?

Strontium carbonicum is a homeopathic single remedy made from strontium carbonate, a white mineral salt. In homeopathy it has been used for sprains and weak ankles that keep giving way, for hot flushing of the face, and for slow healing after a bone injury. It is sold as pills, pellets, drops and creams.

Like all homeopathic remedies, it is made by serial dilution. A small amount of the mineral is mixed into water or alcohol, shaken, and then diluted again and again. At 30C, the most common strength, the dilution has gone so far that essentially none of the original strontium carbonate is left in the pill.

Here is the honest verdict. Homeopaths have written about this remedy for well over a century, but that long use is not proof that it works, and this is the only place in this page we will say so. No published human trial has tested Strontium carbonicum for any condition, and trials of homeopathy in general do not separate it from placebo (a dummy treatment).

How does Strontium carbonicum work?

There is no accepted explanation for how this remedy could work in the body.

Homeopathy rests on two old ideas. The first is "like cures like": a substance that causes symptoms in a well person is said to treat similar symptoms in a sick one. The second is that shaking at each dilution step leaves some kind of imprint behind.

Neither idea matches what chemistry and physics tell us. At 30C there are no molecules of the source mineral left to act on your cells. So any benefit people notice is best explained by placebo (feeling better because you expect to), by normal healing over time, or by the care and attention of the consultation itself.

What forms does Strontium carbonicum come in?

Common forms include:

Sugar pellets or small round pills, usually placed under the tongue.

Liquid drops in a water and alcohol base.

Tablets that dissolve in the mouth.

Creams and gels that list it alongside other remedies.

Strengths are written as 6C, 30C, 200C or as 3X, 6X, 12X. The higher the number, the more times it has been diluted, and the less source material it can possibly contain.

Where it comes from:

Strontium carbonicum was introduced into homeopathic practice in the 1800s and appears in the classic materia medica texts, including the writings of Constantine Hering and James Tyler Kent.

Those texts describe it as a remedy for chronic sprains, ankles that turn easily, flushes of heat in the face, and a sense of faintness after injury or blood loss. It has always been a minor remedy rather than a first-line one.

It is used today mainly by classical homeopaths who prescribe on the full picture of a person's symptoms.

What does Strontium carbonicum help with?

• Long-standing ankle sprains and ankles that give way: This is the picture most linked to the remedy in homeopathic books, especially where the sprain never fully healed and the ankle keeps rolling. No human trial has tested it for sprains. Most sprains improve on their own over weeks, which makes personal reports hard to read. Rest, ice, support and guided strengthening exercises have real evidence behind them. Use those first.
• Hot flushes and a red, burning face: Old texts describe heat rising to the face with a red, burning feeling, sometimes in older people or around menopause. There is no trial evidence for this remedy in hot flushes. Reviews of homeopathy for menopause symptoms have not shown a clear benefit over placebo. If flushes are disrupting your sleep or daily life, talk to your doctor about options that have been tested.
• Slow recovery after a bone injury: Homeopaths have used it where bones are slow to knit and the limb feels weak afterwards. This traditional link is easy to confuse with a separate fact: prescription strontium salts were once studied for bone density. That research says nothing about a homeopathic dilution, which contains no strontium at 30C. A bone that is healing badly needs medical review, not a home remedy.
• Cramping in the calves and feet: Cramps and drawing pains in the legs appear in the remedy picture in the old books. No published human study supports this use. Frequent night cramps can point to low fluids, certain medicines or a circulation problem, so they are worth mentioning to your doctor.
• Faintness and weakness after injury or surgery: Classical texts mention it for people who feel cold, faint and drained after blood loss or an operation. There is no trial evidence here, and this is a setting where delay can be dangerous. Feeling faint after surgery should always be reported to your surgical team.

Which foods are rich in Strontium carbonicum?

1. Seafood and shellfish: take up strontium from sea water
2. Leafy greens such as spinach and kale: draw it up from soil
3. Whole grains: contain small natural amounts
4. Tap and mineral water: the main everyday source for most people

Practical Tips:

These foods carry trace natural strontium in normal safe amounts; they are not a substitute for the remedy and the remedy is not a substitute for them.

What are the side effects of Strontium carbonicum?

• No effects at all, which is the usual experience at 30C
• A short flare of your symptoms in the first days, called an aggravation by homeopaths
• Mild mouth or tongue irritation from the drops, which contain alcohol
• Upset stomach if a low dilution is taken in large amounts
• Rare allergic rash or itching, usually to something else in the product
• Harm from delay if it is used in place of care you actually need

Good to know:

Direct side effects are rare at high dilutions such as 30C, because there is nothing active in the pill except sugar.

The real risks sit elsewhere. Low dilutions like 3X or 6X can contain small real amounts of strontium, a metal that behaves like calcium in the body. And any remedy can cause harm if it delays treatment for a problem that needs a doctor.

Tell your doctor and pharmacist everything you take, including homeopathic products.

How much Strontium carbonicum should you take?

• Recommended daily: There is no scientifically established dose, because there is no measurable active ingredient to dose at 30C. What homeopaths and product labels usually suggest: Pellets: 3 to 5 pellets under the tongue, left to dissolve. Drops: 5 to 10 drops in a little water. Frequency: once to three times a day for a short spell, or a single dose of a higher strength given by a practitioner. Follow the label on the product you actually bought. Never take a low dilution such as 3X in large or repeated amounts, since those can still hold real strontium.
• Best time of day: Any time of day. Homeopathic practice suggests taking it in a clean mouth, about 15 minutes away from food, drink, coffee, mint or toothpaste. That is custom, not a tested rule.
• With or without food: Usually taken between meals, on a clean mouth. Food does not make it unsafe.
• Time to effect: No reliable time frame exists. People who report a change usually describe it within a few days. Any change that quickly may simply be the natural course of the problem.
• How long to take it: Keep any trial short. A week or two is enough to see whether you feel any different. If nothing has changed, stop. If your symptoms are getting worse at any point, stop sooner and get your symptoms checked. Do not take it for months on end for an unexplained problem that has never been looked at by a doctor.
