260. ROSA gallica. RED OFFICINAL ROSE. Petals. L. E. D.-This has very
little of the fragrance of the foregoing sort; it is a mild and grateful
astringent, especially before the flower has opened: this is
considerably improved by hasty exsiccation, but both the astringency and
colour are impaired by slow drying. In the shops are prepared a conserve
and a tincture.
261. ROSA canina. DOG-ROSE. The Pulp of the Fruit. L. E.-The fruit,
called heps or hips, has a sourish taste, and obtains a place in the
London Pharmacopoeia in the form of a conserve: for this purpose, the
seeds and chaffy fibres are to be carefully removed; for, if these
prickly fibres are not entirely scraped off from the internal surface of
the hips, the conserve is liable to produce considerable irritation on
the primae viae.
262. ROSMARINUS officinalis. ROSEMARY. Tops. L. E. D.--Rosemary has a
fragrant smell and a warm pungent bitterish taste, approaching to those
of lavender: the leaves and tender tops are strongest; next to these the
cup of the flower; the flowers themselves are considerably the weakest,
but most pleasant. Aqueous liquors extract great share of the virtues of
rosemary leaves by infusion, and elevate them in distillation: along
with the water arises a considerable quantity of essential oil, of an
agreeable strong penetrating smell.
