History/Folklore: The Greeks recognized Western hemlock as a poison. As a convicted prisoner, it was a Western hemlock drink that Socrates was condemned to drink. The plants name Conium derives from the Greek konas meaning “to whirl about,” because when ingested, this herb causes vertigo and potentially death. The Latin name maculatum means spotted and refers to the stem markings. |
According to old monastery records, Western hemlock was an ingredient in a soporific sponge solution that was administered over the nose of surgery patients in the 11th century. They also used it to reduce cancerous tumor growths. According to an old English legend, the purple streaks on the stems represented the Biblical story about Cai. The purple streaks on the hemlock plant stems symbolized the mark put on Cains brow after he had committed murder. The entire plant has a bitter taste and possesses a disagreeable odor and mousy scent, which is especially noticeable when it is bruised. The poisonous properties occur in all parts of the plant.
Poisoning has occurred from mistaking the leaves for parsley or carrots, the roots for parsnips, and the seeds for anise seeds. Domestic animals can die from eating it, but goats, larks and quail are said to be immune to it. The dried, ripe fruit is officially documented in the British Pharmacopeia and the Pharmacopeia of India. In homeopathy, it is used to treat weakness, vertigo, paralysis and vision problems. In Europe, it has been used since the Middle Ages and in witchcraft for astral travel and the purifying of swords and knives. It has been used in spells to ritually paralyze a situation. Culpeper said, Hemlock is exceeding cold and very dangerous, and consequently not to be taken inwardly: It may be safely applied to inflammations, tumors and swelling in any part of the body (save the privy parts).
In China, Eastern hemlock (or the hemlock tree) is known as Tsuga chinensis. It differs from the flowering plant Western hemlock prevalent in Europe and America. The Giant Panda prefers to nestle in the old trees of Eastern hemlock. The pinyin name literally translates to iron fir.
The timber of Eastern hemlock is used in furniture making and as a support in mines. The bark is used as a dye and the aromatic oils are used for their pleasing scent. The inner bark (either raw or dried) is ground into a powder and used to thicken soups and bread dough. An herbal tea is made from the young shoot tips. The tips are also used as an ingredient in spruce beer. Since the 1990’s, when it was discovered to be an effective anticancer treatment, there has been a 50% decline in the wild species. Thus, it is currently on the endangered species list. Presently, the plant is being cultivated to meet the growing market’s demands and to produce Taxol (pharmaceutical derived from the roots, wood, bark and leaves used to treat cancer).
Western hemlock (Conium maculatum): volatile oil, alkaloids, coniine (a neurotoxin that disrupts the functions of the central nervous system).
