ChamaePitys lutea vulgaris five folio trifido C. B. Abiga & ajuga quibusdam. Teucrium Chamaepitys Linn. Groundpine: a low, hairy, creeping plant, with square stalks; whitish clammy leaves, cut deeply into three long narrow segments like those of the pine tree, let in pairs at the joints; and yellow labiated flowers, without pedicles, and wanting the upper lip. It is annual, grows wild in sandy and chalky grounds in some parts of England, and flowers in July.
The leaves of groundpine are moderately bitter, and of a resinous, not disagreeable smell; approaching in this respect, as in their external form, to those of the pine tree. They are recommended as aperients, and corroborants of the nervous system; and said to be particularly serviceable in female obstructions, paralytic disorders, and when continued for a length of time, either by themselves or with the assistance of germander, in rheumatic, ischiadic, and gouty pains.
The leaves in substance, dried and powdered, are directed to be given from half a dram to a dram. Their virtues are extracted both by water and spirit, mod perfectly by the latter: the aqueous tinctures are yellowish, the spiri-tuous green. In distillation, they weakly impregnate water with their resinous scent: on distilling large quantities of the herb, a little essential oil may be collected, in quality some-what approaching to that of turpentine. The watery extract has, joined to its bitterness, a weak saline austerity; the spirituous, a slight sweetishness and warmth.
