Ligustrum, _Privet_; its leaves and tops are possessed of mixed powers, being discutient and astringent, and desiccative without pain or pungency. Hence the decoction of it, when poured on a part, is useful for burns, and agrees with inflammations of a hot nature. When chewed it also relieves aphthæ, and is mixed up with splenic remedies. * * * * * COMMENTARY. We must decline entering upon the general literature of this subject, which has created a good deal of discussion. Suffice it to say, that we have now no hesitation in deciding it to be the _Lawsonia inermis_, namely, the plant from which the henna of Egypt is obtained. See Lindley’s Veg. King. (575.) It is used by females for staining their hands and feet of an orange colour. Dioscorides mentions that an infusion of its leaves in the juice of saponaria, or soapwort, was used for painting the hairs yellow. He says of the ointment prepared from it (unguentum cyprinum), that it is calefacient, emollient, and fragrant. (i, 124.) Galen, Aëtius, and Oribasius give it the same characters as our author. The Arabians describe it under the name of _alcanna_, which seems to be _henna_ with an Arabic prefix. See in particular Serapion (De Simpl. 110), and Avicenna (ii, 2, 50.) Both copy freely from Dioscorides and Galen. They say its virtues in female complaints are similar to those of the Sanguis Draconis. All praise it as a vulnerary herb, and a good application in cases of burning. They further commend it in pleurisy and quinsy as a plaster. Ebn Baithar treats of it at very great length. (i, 338.) It would appear that the privet is still used as a medicine and dye by the native physicians of Hindostan. See a very interesting account of it in Ainslie’s Mat. Indica (ii, 190.) Κύτισος, Cytisus; its leaves are of a gently discutient and tepid nature, like those of melons. * * * * * COMMENTARY. After maturely weighing the opinions which have been held respecting this classical herb, we have no hesitation in agreeing with those who refer it to the _Tree-medick_ (_Medicago arborea_ L.) Dioscorides says its leaves are cooling and discutient when applied externally, and diuretic when taken in decoction. (iv, iii.) Galen and the other Greek authorities treat of it very succinctly, like our author. Avicenna briefly recommends it as a diuretic medicine, and one which is applicable in diseases of the spleen. (ii, 2, 24.) Κώνειον, Cicuta, _Hemlock_; that it is possessed of extremely cold powers is obvious. * * * * *
