An Experiment has been made upon a Dog, by giving him the _Nux Vomica_, which soon poisoned him. The _American Physick Nut_ is said to be so poisonous, that no Animals make a near Approach to it. Wormwood in _Persia_ is so venemous, that if Horses, or any other Creatures, eat thereof, they die immediately; upon which account, say the Duke of _Holstein_’s Ambassadors, we durst not unbit that day[36]. The _Indians_ have what they call _Juico Juice_ among them, which deprives such as drink of it of their Reason, and renders them perfect Idiots; tho’ at the same time it leaves them in the perfect Enjoyment of their Health and natural Powers. Footnote 36: Their Voyages and Travels to _Muscovy_ and _Persia_, p. 228. A. D. 1637. _CHARCOALS_ prepared from _Vegetables_, have a poisonous Quality; for, when kindled, they exhale a Vapour, which, if it be kept up, and confin’d to a close Place, proves fatal. ’Tis said, Charcoal made in _Cornwal_ affords a manifest arsenical and sulphurous Smell beyond others; and yet Charcoal is a _commodious_ Fuel. Even when the sharp Points of Nettles pierce the Flesh, they instil a kind of venemous Juice into the Wound, which gives a painful Sensation. The Leaf of a Nettle has some relation to a Sting; ’tis covered with very sharp Prickles, whose Base, which is a Bladder of a flexible Substance, has a Hole in the middle, by which this venemous Liquor runs into the wounded Part, and excites Pain. This may be easily perceived with a Microscope; if a Man press with the Finger, the End of those Prickles against its _Base_: for then, thro’ these Prickles which are transparent, this Liquor is manifestly seen to mount, and to descend, as the ingenious Mr. _Hook_ assures us, he had often made the Experiment. In _Carmania Deserta_, towards the _Persian_ Gulph, they have two sorts of dangerous Shrubs, one called _Gulbad-Samour_, i. e. the Flower that poisons the Wind, where there are many of these _Shrubs_. The Wind that passes thro’ them, kills those who are near it. The other is _Kerzehre_, the _Gall_ of _Asses_, because it kills those Creatures, and others that eat of it; yea, the Water that falls from it is poisonous. They say, that Part of its Root which spreads to the East is Poison: for which, that on the South-side is an Antidote[37].——_N. B._ Is not our Author mistaken? for can any Poison grow in the delicious Plains of the East, consecrated to the Service of the Altar and Knee? Footnote 37: _Tavernier_, in _Atl. Geo._ p. 349, and 396. An Overdose of Opium, which is the condensed Juice of Poppies, is poisonous. The _Turks_ take _Opium_, which they call _Affion_, without any Preparation, it being merely the Juice of black Poppy, dried in the Sun, without any purification. It is wonderful, _that use should make that Liquid which is Poison to us, a Cordial to them_[38]. Footnote 38: _Wheeler_’s Voyages, p. 203.
