YewPOISON!
Botanical: Taxus baccata Family: N.O. Taxaceae and Coniferae
---Poisonous Parts---Leaves, seed and fruit.
---Habitat---Europe, North Africa, Western Asia.
---Description---A tree 40 to 50 feet high, forming
with age a very stout trunk covered with red-brown, peeling bark and
topped with a rounded or wide-spreading head of branches; leaves spirally
attached to twigs, but by twisting of the stalks brought more or less into
two opposed ranks, dark, glossy, almost black-green above, grey,
pale-green or yellowish beneath, 1/2 to 1 1/2 inches long, 1/16 to 1/12
inch wide. Flowers unisexual, with the sexes invariably on different
trees, produced in spring from the leaf axils of the preceding summer's
twigs. Male, a globose cluster of stamens; female, an ovule surrounded by
small bracts, the so-called fruit bright red, sometimes yellow, juicy and
encloses the seed.
No tree is more associated with the history and legends of Great
Britain than the Yew. Before Christianity was introduced it was a sacred
tree favoured by the Druids, who built their temples near these trees - a
custom followed by the early Christians. The association of the tree with
places of worship still prevails.
Many cases of poisoning amongst cattle have resulted from eating parts
of the Yew.
---Constituents---The fruit and seeds seem to be
the most poisonous parts of the tree. An alkaloid taxine has been obtained
from the seeds; this is a poisonous, white, crystalline powder, only
slightly soluble in water; another principle, Milossin, has also been
found.
---Uses---The wood was formerly much valued in
archery for the making of long bows. The wood is said to resist the action
of water and is very hard, and, before the use of iron became general, was
greatly valued. (In homoeopathy a tincture of the young shoots and also of
the berries is used in a variety of diseases: cystitis, eruptions,
headache and neuralgia, affections of the heart and kidneys, dimness of
vision, and gout and rheurmatism. - EDITOR)
