Track Carboneum sulphuratum with reminders and record whether it helped, in the app.
Carboneum sulphuratum is a homeopathic remedy. It is made from carbon disulphide, a strong-smelling liquid used in factories. Its Latin name is Carbonei disulphidum.
Homeopaths use it as a single remedy. They give it for numb or burning hands and feet, weak legs, and dim sight. These match the signs seen in workers who breathed the raw chemical.
The source is watered down again and again. At 30C, none of it is left. Trials do not show it beats a dummy pill (a placebo).
So treat its long use in homeopathy as history, not proof. It is not a cure, and it must not replace care from your doctor.
Honest answer: there is no known way for it to work in the body.
Homeopathy rests on two old ideas. The first is 'like cures like': a thing that causes signs in a well person is said to ease those same signs in a sick one. The second is that shaking at each step of watering down leaves some kind of imprint.
Neither idea fits what we know about chemistry. At 30C there is no source left to act on you.
Any relief people feel is best put down to placebo, to time, and to being listened to.
It comes as small sugar pellets, as tablets, or as drops.
Common strengths are 6C, 12C, 30C and 200C. The letter C means each step waters the last one down 100 times. A higher number means more watering down, not more power.
Drops are usually mixed in alcohol. Pellets are usually made of lactose (milk sugar) or sucrose (table sugar). Ask for pellets if you avoid alcohol.
Carbon disulphide was first made in the 1790s. Factories used it widely through the 1800s.
Homeopaths took it up in the mid-1800s. Its picture came from provings, where healthy people took it and wrote down what they felt. Reports from sick factory workers added to that picture.
It has stayed a small, rarely used remedy. You can find it in old homeopathic texts such as Allen's Encyclopedia and later materia medica books (lists of remedies).
Some reactions to Carboneum sulphuratum need urgent care. Call your local emergency number or go to an emergency department straight away — do not wait to see whether it passes.
Get urgent help if someone swallows the raw chemical or a strong liquid form, or if they become confused, drowsy, or have a fit. Call your emergency number.
See a doctor the same week if numbness or tingling is spreading, your legs feel weak, you stumble, your sight is dim or blurred, your chest hurts, or your mood or memory has changed.
See a doctor sooner rather than later if your symptoms have not settled in two weeks, or if you feel worse after starting this remedy.

Reviewed by the HealisticMD editorial team How we grade evidence →
The published evidence for Carboneum sulphuratum is weak or absent. That usually means no controlled trial has tested it, not that a trial found it ineffective — the two are different, and we grade only what has been published.
What it is typically used for, usual dose, cautions, and the study behind it where real trial data exists.
