Cicuta virosa
Water hemlock, cowbane. · Plant · Apiaceae
Cicuta has an affinity with the nervous system and is used both for nervous temperamental conditions and for physical disorders of the nervous system. It is generally given to people who behave childishly and do absurd things. They may be wild, delirious, and overexcited, or exhibit great sensitivity to sad stories and to the happiness of other people. Alternatively, they may be distrustful, despise other people, and have an aversion to society. Their memories can go blank for long periods. Classic physical symptoms associated with Cicuta focus on spasmodic effects on the nervous system, ranging from stammering and hiccups to sudden, strong jerks and spasms. Petit mal fits with long absences may be treated with the remedy, as may epilepsy or violent convulsions accompanied by facial contortions and severe backward twisting and arching of the head and neck.
The remedy may also be used for some skin disorders, often involving pustules that leave yellowish scabs, such as eczema or impetigo. The head and face may be most affected, or the whole body may develop chronic eruptions that itch, burn, and crust. A craving for chalk may occur, as may an inability to distinguish what is edible.

Dose
Sixth to two hundredth attenuation.

This remedy is of interest because of its convulsive tendency. It puts the whole nervous system in such a state of increased irritability that pressure on a part causes convulsions. The convulsions extend from center to circumference; the head, face and eyes are first affected.
Convulsions
An aura in the stomach gives warning of the convulsion. Some complaints spread from the chest, especially from the heart; the rigors and chills begin in the chest; and there is a sensation of coldness about the heart; and from there it extends to other parts.
Convulsions often begin about the head and throat and extend downward. The whole body is in such a state of tension that, after excitement, a fire rages throughout the economy and causes convulsions. Any irritation in the throat or oesophagus will cause violent convulsions in this region.

Twitching and spasmodic jerks are a keynote of Cicuta. "Bending the head backward" is very characteristic. The remedy has cured many cases of cerebro-spinal meningitis, the opisthotonos being the leading indication. Violence is a leading feature: violent spasms; moans and howls; great agitation; makes …
