Dorste Nia

(From Dr. Dorston). See Contrayerva.


The back. Most etymologists derive it from deorsum, because it bends downwards; antister-r.on, and metaphrenon; but this last appellation properly means the part between the shoulders. We use the term back in a figurative sense, as the back of the head; and the epithet dorsalis is applied to diseases originating apparently from the back.

A gibbosity is a preternatural incurvation of the spine of the back, either to the posterior or to the lateral parts. It generally happens from external causes, as blows, tight stays, &c; sometimes from a relaxation of the ligaments of the belly, or from scrofula. Gouey gives an instance of it from a preternatural contraction of the muscles of the belly. See Heister's Institutes of Sur-ijerv, and Distortio spinae.

(From Draba 3032 to seize; so called from the sudden effect on the nose of those who eat it,) lepidium Arabis; Arabian mustard and turret cressus. Iberis umbellata Lin. Sp. Pi. 906 ? The seeds serve as pepper in seasonings, but are not used as a medicine.


(From the Hebrew drachmon). Among the Greeks this was the name of a coin; and of a weight divided into six oboli. The Romans reckoned eight drachms to an ounce, and twelve ounces to a pound: in our apothecaries' present weights, the drachm makes three scruples, or sixty grains.


(From Draco 3033 a dragon; because its flowers resemble the mouth of a dragon,) tarachon, dracuncu-lus hortensis, abrotarium lilii folio, tarragon. Artemisia dracunculus Lin. Sp. Pi. 1189.

The leaves of this herb resemble those of hyssop, and their scent that of fennel: the flowers grow on the top of the plant, and appear like those of southernwood. It grows in gardens, and flowers in July and August; is warm and stomachic, used as a condiment, but not employed in medicine.

Draco Ntium

(From Draco Ntium 3036 a dragon; from its root resembling a dragon's tail,) dracunculus polyphyl-lus, colubrina, dracontia, Erva de Sancta Maria, giga-rus serpentaria, arum polyphyllum, dragon's and many-leaved arum. Arum dracunculus Lin. Sp. Pi. 1367. It is a plant with smooth glossy leaves, set on long pedicles; the stem is single, thick, whitish, and variegated with purple streaks; on the top is a long sheath, including a dark coloured pistil, like that of arum, but larger, succeeded by a cluster of red berries. The root is large, rather round, externally inclining to yellow, and internally white. It is perennial; a native of the southern parts of Europe.

Its botanical analogy and its medical virtues render it a good substitute for the arum; and the same pharmaceutic treatment is necessary. See Arum
