The witches in _Macbeth_ include it in their accursed brew:--

"Liver of blaspheming Jew,

Gall of goat, and _Slips of Yew_."

The Yew tree is called "Hebon" by Spencer, and "Jew of Malta" by

other writers of Shakespeare's time. The leaves are bitter, nauseous,

and acrid. The succulent covering of the fruit is soft and slimy,

mawkishly sweet, and mucilaginous. The leaves have a dangerous

effect on the circulation of the heart, and when taken with any

freedom are as fatal as the Foxglove.

Before the new Shakespeare Society, 1882, it was contended and

proved to the satisfaction of the Society, that "the cursed Hebena,"

the "leperous distilment poured into the chambers of mine ears,"

told of, so pathetically, by the sad ghost of Hamlet's father, was the

[622] poison of the Yew, and identical with Marlow[e]'s juice of

Hebron.

Ray mentions that a gardener employed in clipping a Yew tree at

Pisa, could not proceed with his work for more than half-an-hour at

a time without being seized with a violent pain in the head.

Nevertheless, deer, sheep, and goats can eat the foliage with

impunity.

The fresh leaves were administered to three children near

Manchester for worms. Yawning and listlessness came on, and the

eldest vomited a little, but neither of them complained of any pain.

They all died within a few hours of each other.

Because being then green, on the Sunday next before Easter, the

branches of the Yew tree have been used as a substitute for the

Palms which symbolise the entry of Jesus into Jerusalem.

The symptoms induced by provings of the leaves and juice in toxic

quantities, have been sick headache, with giddiness, feeble, faltering

pulse, coldness of the extremities, diarrhoea, and general

prostration. So that for this combination of symptoms, as in severe

biliousness, or as in the auditory vertigo of Meniere's disease, small

doses of the diluted tincture are found to give prompt and effectual

relief. The leaves contain a volatile oil, tannin, and a bitter

principle "taxina," which is also furnished by the seeds. An extract

of Yew has been pronounced a useful narcotic by more than one physician

of repute: and in some parts of Germany a decoction of the wood is

a well-known remedy against hydrophobia.

A jelly prepared from the berries has been given for chronic

bronchitis, and the leaves have been used for epilepsy; likewise they

have been taken by ignorant persons to induce abortion, but with

serious injury to the experimenter. In some rural districts the berries

[623] are known as "Snots"; whilst the wood and roots are "Wire

thorn."

By an old statute of Edward the First, trees were required to be

placed in churchyards to defend the church from high winds, the

clergy being allowed to cut them down for repairing the chancel

when necessary. Perhaps, partly for this reason, the Yew was

commonly planted by the side of a newly-built church. That its

wood was certainly employed for making bows, we learn from

Shakespeare:--

"Thy very beadsmen learn to bend their bows

Of double-fatal Yew against thy state."

It was "double-fatal," because the leaves and fruit seeds are

poisonous, and the bows made from its branches, as well as arrows

armed with its deadly juice, were instruments of death.

Against the maladies which have been specified as indicating the

tincture of Yew for their cure, from five to ten drops of the third

decimal tincture should be given, with a spoonful of water, every

two, three, or four hours, whilst required. In Switzerland the Yew is

known as William's tree, in memory of Tell. Formerly the name was

spelt "Eugh," "Yeugh," and "Ewgh."
