(From Chamaedrys 1992 and the oak).

Germander. Chamaedrys minor repens; vulgaris. Also called quercula calamandrina, trissago; chamae-drops P. AEginetae and Oribasii. Small germander, and English treacle. It is the teucrium chamaedrys Lin. Sp. Pi. 790. Creeping germander.

The chamaedrys is a small, creeping, shrubby plant, with square stalks, small, stiff, oval leaves, notched from the middle to the extremity, like those of the oak tree, set in pairs at the joints, and purplish labi-ated flowers, set thick together, wanting the upper lip. It grows wild in France, Germany, and Switzerland. It is sometimes found wild in England, but is generally raised by culture in gardens. It flowers in June and July.

The leaves and tops are slightly bitter and aromatic; and esteemed mildly aperient and corroborant. They have been held in esteem in uterine and rheumatic complaints; in intermittent fevers; scrofulous affections, and other chronic complaints. At present, however, they are little used. The best time for gathering this herb is when the seeds are formed, and the tops are then preferable to the leaves. When dry, the dose is from 3 ss. to 3 i. Either water or spirit will extract their virtue; but the watery infusion is more bitter. This plant is an ingredient in the noted powder, called from the duke of Portland, of which we add the original receipt.

Take of the roots of round birthwort and gentian, the tops and leaves of small germander, lesser centaury, and ground pine, of each equal parts: powder them all together. Of this powder a drachm must be taken, in any convenient liquor, every morning, fasting, for three months; then two scruples for three months; and, after that, half a drachm for six months: and, to conclude the process, half a drachm every other day for a year. AEtius calls a powder similar to this, antidotes ex duobus cen-tauree generibus; Coelius Aurelianus, diacentaurion.

Experience, in general, hath tended to lessen the credit of this composition, which hath little more than its antiquity to support the character with which it was lately raised. It differs but little from the diacentaureon of Coelius Aurelianus, the pulvis principis Mirandolae, climax vel scala sacra, and others, of which an account is given in the Lond. Med. Obs. and Inq. vol. vi. p. 126, where also the origin of the duke of Portland's powder is traced back to these boasted remedies. We need not add on this subject to our former observations on bitters, and on the gout cordial. See Amara, and Arthritis.
