Track Cortisonum with reminders and record whether it helped, in the app.
Cortisonum is a homeopathic remedy. It is a single remedy made from cortisone acetate. Cortisone is a man-made copy of a hormone made by the adrenal glands (two small glands that sit on top of the kidneys).
The Latin name is Cortisonum aceticum (hormone corticosurrenale). It is also sold as Cortisone. Homeopaths give it for stiff joints, itchy skin and low energy.
The starting material is shaken and watered down over and over, a process called serial dilution. At the common 30C strength, none of the starting cortisone is left. You swallow a sugar pill or a drop of water and alcohol.
Trials do not show it works better than a dummy pill (placebo). It is used in homeopathy, but long use is not proof that a remedy works. This page says what is known and what is not.
There is no known way for it to act on the body. At 30C there is nothing of the starting cortisone left to act.
Homeopaths follow an old rule called "like cures like". They say a substance that causes signs in a well person can, in tiny doses, help a sick person with the same signs. They also say that shaking each step leaves an "imprint" in the water.
That idea has not been shown to be true in the lab or in people. It is a belief within homeopathy, not a proven way of working.
It comes as small sugar pills or tiny round granules that melt under the tongue. Liquid drops in water and alcohol are also sold.
Common strengths are 6C, 9C, 12C, 15C, 30C and 200C. The higher the number, the more times it was watered down. Some brands sell 3X, 6X or 9X, which are less dilute.
Cortisone was first made in the 1930s and used as a medicine from 1948. Homeopaths added it to their remedy list soon after, based on a "proving" (a test where healthy people take a remedy and write down what they feel).
So this is a modern remedy, not an old folk one. It is used in one tradition only, mostly in France and other parts of Europe.
See a doctor if your joint pain, rash or tiredness lasts more than a few weeks, or gets worse at any point.
Get help the same day if you feel very weak or dizzy, keep being sick, have belly pain or feel faint when you stand up. These can be signs that your body is short of steroid hormone, which is serious.
Call emergency services if you have trouble breathing, swelling of the lips or throat, chest pain, or if someone becomes confused or cannot be woken.
