Caladium seguinum is a homeopathy remedy. It is made from dumb cane, a leafy house plant. The plant's Latin name is Dieffenbachia seguine.
People take it for weak sexual response, itching around the genitals, and the wish to smoke. Some also use it for itchy bug bites. These uses come from old case notes kept by homeopaths.
The plant is watered down again and again to make the remedy. At the common 30C strength, none of the plant is left in the pill. Trials do not show it works better than a dummy pill (placebo).
Long use in a tradition is not proof that a thing works. We say that once here, and it holds for every use listed below.
Homeopathy rests on an idea called 'like cures like'. The raw plant numbs and swells the mouth. So homeopaths give a tiny, watered-down dose of it for problems they see as like that, such as a numb or weak sexual response.
To make the remedy, one drop of plant extract goes into 99 drops of water and alcohol. The mix is shaken hard. That step is done again and again — 30 times for a 30C remedy.
After about 12 steps, not one bit of the plant is left. So a 30C pill is just sugar, water and alcohol. Homeopaths say the liquid holds a 'memory' of the plant, but there is no known way this could work.
Tests do not back the idea up. When studies are run well, the remedy acts like a dummy pill (placebo).
Sugar pellets are the most common form. They are small and sweet, and you let them melt under the tongue. Most are made of lactose (milk sugar) or cane sugar.
You may also see liquid drops in an alcohol base, pressed tablets, and creams. The mother tincture (the first, full-strength plant extract) is sold in some places but is not a home product.
Common strengths are 6C, 30C and 200C. You may also see 3X, 6X and 12X, which are watered down in steps of ten rather than steps of a hundred. The higher the number, the less plant is left — at 30C, none is left at all.
Dumb cane grows wild in the West Indies and warm parts of the Americas. Chewing a leaf makes the mouth swell so much that speech is hard. That is how the plant got its name.
The homeopath Constantine Hering is credited with testing the plant on healthy people in the 1800s. His notes shaped the uses still listed today. William Boericke later put it in his materia medica (a reference book of remedies).
Outside homeopathy, the plant has no real record as a medicine. It is known mainly as a house plant and as a poison.
Some reactions to Caladium seguinum 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 the lips, tongue or throat swell, if breathing or swallowing becomes hard, or if a child or pet has chewed a dumb cane leaf.
See a doctor the same week if you have new or worsening erection problems, genital itching with sores, a discharge, a lump or bleeding, or a bite with spreading redness, pus or fever.
Also see a doctor if itching all over the body lasts more than two weeks, if you have night sweats or weight loss you cannot explain, or if two weeks on this remedy have changed nothing.
