Nat. ord., Simarubaceae.
The Tree of Heaven. For. names: German, Goetterbaum; French, Ailante.
Characters. - A deciduous tree of the first rank, growing to the height of 60 feet and upwards. Its straight, erect, columnlike trunk, from 2 to 3 feet in diameter, its gigantic boughs and shoots, clothed with large pendulous leaves, give it a noble appearance. Leaves from l 1/2 to 6 feet in length, pinnate, with an odd one, and having leaflets with coarse glandulous teeth near the base. Flowers in rather large compact panicles, of a whitish-green colour, exhaling a disagreeable odour.
A short proving exists in North American Journ. of Horn., vol. vii., p. 385, and a case of poisoning is recorded by Dr. P. P. Wells in American Horn. Review, March, 1864, from the symptoms of which he suggested it as a remedy for Malignant Scarlet Fever, in which disease it has done signal service. See a paper by Dr. Chalmers in Monthly Horn. Review, vol. xii., p. 713. See also Hale's New Remedies.
Parts employed. - Dr. Hale recommends the use of the fresh well-developed flowers, and of the fresh bark of the young shoots and roots in equal parts.
The poisoning was caused by the sap of the young and tender shoots, gathered during the flowering of the tree.
Preparations. - Tincture in each case.
