Physiological Action-

Oenanthe crocata is extremely poisonous, and from its resemblance to common garden parsley has frequently caused death in men and animals. Toxic doses cause burning heat in the throat and stomach, with disturbance of intellect, cardialgia, nausea, vertigo, violent convulsions, furious delirium, or profound sleep; loss of sight, hearing and speech; rolling of the eye-balls upward, feeble pulse, abolition of sensation and of motive power, with increasing intellectual dullness. There are universal chills, rose-colored spots on face, breast and arms; lividity and swelling of the face, with trismus and bloody froth from mouth and nostrils, stertorous breathing, coma, death.
Autopsies performed on patients dead from the accidental use of this agent have shown an engorgement of the blood vessels of the brain and cord. There was effusion of blood and bloody serum in the occipital foramen. The sinuses of the dura mater and the veins of the pia mater also were distended with blood, as were also the sinuses of the vertebrae. There were apoplectic foci in the cerebral mass. There was serous effusion in the cellular tissue beneath the arachnoid, in the ventricles and at the base of the brain. Therapy-The agent acquired a reputation in the treatment of epilepsy. It has cured a few violent cases and very many cases of petit mal. Fisk reported five cases cured, and other trustworthy investigators have had similar results. It is indicated in those cases which, instead of fullness of the capillary vessels of the brain and spinal cord, there is anemia of these organs more or less marked. This distinction was made by Henning, and is an important one.
It has proved of value in cases where epilepsy has resulted from injury, in cases where there is an impairment of the brain structure and imperfect cerebral circulation with impairment of the nutrition of the brain.
It has not increased in reputation, nor has our knowledge of its action increased greatly during the past fifteen years. It deserves a closer investigation.

 
Symptoms may include:

Salivation, dilated pupils, convulsions and death, which usually rapidly follows ingestion of the plant. If the horse does survive, one or more limbs usually remain paralysed.
 

This most poisonous of our indigenous plants is not official and has never been used to any extent in medicine, though in some cases it has been taken with effect in eruptive diseases of the skin, being given at first in small doses, gradually increased.
Great caution must be exercised in the use of the tincture. The dose of the tincture is 1 to 5 drops. The roots have likewise been used in poultices to whitlows and to foul ulcers, both in man and horned cattle.

Due to polyacetylenes. Active principle oenanthe- toxin, a convulsant, causes rapid death.
Symptoms: Great agony, sickness, convulsions. paralysing speech, death.

HUMAN CASES: Of mistaking leaves for celery, tubers for parsnip. A party of workers repairing
a breach in a towing path dug up a plant and ate them in their sandwiches. in 3 hours they were
dead. 8 boys ate the roots, five died, other three had violent convulsions.

ANIMAL CASES: Horse and cattle poisoning. symptoms: salivations, dilated pupils, spasmodic
convulsions. Pigs vomit and die suddenly. Sheep: 50% will recover. If sheep are chloroformed
to control spasms, nembutal can be injected.

Ehret, flower draughtsman, l8thC : when drawing the flower, it rendered him so giddy
he had to quit the room several times to recover.
