Glonoinum is a homeopathy remedy. It is made from nitroglycerine, the same drug doctors use for chest pain. Homeopaths give it for a hot, pounding headache and a red, flushed face.
The remedy is made by diluting the drug again and again. At 30C, none of the source drug is left. What you take is mostly water, alcohol or a sugar pill.
Trials do not show that it works better than a dummy pill. Its standing comes from long use in one tradition. Long use is not proof that a remedy works.
No one has shown a way for this remedy to work in the body. That is the honest starting point.
Homeopathy uses the idea of "like cures like". Raw nitroglycerine can cause a throbbing headache, a red face and a pounding heart. So homeopaths give a very diluted dose for those same signs.
The dilution is the problem. Past about 12C, no molecules of the source drug remain. At 30C there is nothing left to act on you.
Homeopaths say the water keeps a "memory" of the drug. There is no accepted proof for that idea. Any benefit people feel is most likely a placebo effect, which means feeling better because you expect to.
Glonoinum comes in a few simple forms.
Small sugar pellets are the most common. You let them melt under your tongue. Tablets work the same way.
Liquid drops in water and alcohol are also sold. Some shops sell combination headache products that list Glonoinum among several remedies.
Common strengths are 6C, 30C and 200C. Low strengths such as 1X, 2X and 3X are sold in some countries. Those low ones may still contain real drug.
Nitroglycerine was first made in 1847 by Ascanio Sobrero. He tasted a tiny amount and got a violent headache.
Constantine Hering, a homeopath, tested it on healthy people in the 1840s and 1850s. He named it Glonoinum. His notes describe bursting head pain, a red face and a thumping heart.
The remedy has stayed in homeopathy books ever since. It is best known there as a remedy for sun headaches. Doctors later used the same drug for chest pain, but that is a separate story.
Some reactions to Glonoinum need urgent care. Call your local emergency number or go to an emergency department straight away — do not wait to see whether it passes.
Call emergency services now if you have chest pain, pressure or tightness, trouble breathing, or pain spreading to your arm or jaw. Do the same for a sudden headache that is the worst you have ever had.
Get urgent help for a headache with fever, a stiff neck, a rash, confusion, weakness on one side, slurred speech or a fit.
Get urgent help for heat stroke, which can bring hot dry skin, confusion or fainting after time in the heat.
See your doctor soon if headaches are new, more often, or worse than before. Also see your doctor if hot flushes bother you day after day, or if your headache has not eased after 24 hours.
