Toxicity of hemlock

Hemlock is a very poisonous plant. The toxicity depends on the temperature and the soil where it grows. In hot countries the toxicity index is higher than in countries with lower temperature. There are even references that in cold countries this plant has virtually no toxicity, while in countries like Italy or Spain toxicity is very high.

There are also references that in some places the plant has been used for food, so some scholars think that cooking could detoxify it.

There are cases of poisoning in people who have confused the leaves of this plant with parsley (Petroselinum crispum). Other times, its root has been confused with the root of the parsnip (Pastinaca sativa).

With hemlock were executed criminals in Athens mixed with opium so that death took place without being aware of it. Apparently it was this mixture that Socrates drank when he was sentenced to death in 399 BC

The philosopher describes how he felt while the poison was acting. He described how his members were becoming paralyzed from the feet up and how he was fully aware as muscle paralysis occurred. His death occurred when the lungs gradually stopped working. So Plato's accounts in Phaedon:

"But Socrates, after walking around, now told us he was beginning to feel tired legs and immediately lay down. At the same time, the man who had given him the poison looked at his feet and legs, touching them at intervals. At last, he squeezed so violently on his foot, and asked if he was sorry. To which Socrates said no.

The man then pulled the leg and so on, showing that it was becoming cold and stiff. And Socrates, feeling it the same, assured us that when the effects would have amounted to his heart, he would have gone,

and now, feeling half his body becoming cold, he threw aside the clothes and spoke for the last time:

- Crito, we owe the sacrifice of a cock to Aesculapius.

- It will be done - Critón said. Have you anything more to say?

He did not answer, but a moment later his eyes remained fixed. And Crito, seeing this, closed his eyelids and mouth "

- In contact with the skin: hemlock may cause dermatitis in some people.

Is hemlock toxic for animals?

Hemlock is very toxic to all animals. According to some experts, only the goats get rid of its toxicity. The poison of this plant acts quickly after one hour of ingestion, leading most of them to death after two or three hours after the poisoning.

Among the main symptoms we have difficulty swallowing, convulsions and death by paralysis of the respiratory muscles.

Among all the cattle, those most likely to become intoxicated animals are cows and pigs, while sheep do not notice its effects both.

Poisoning usually occurs when animals eat dry hay contaminated with this plant. It is difficult for them to become poisoned with the tender plant because of the smell and taste makes them usually reject it.

Treatment is similar to that applied to humans: stomach emptying, anticonvulsants and neutralizing products, such as tannic acid.
