=Botanical Origin=—_Rosa gallica_ L., a low-growing bush, with a

creeping rhizome throwing up numerous stems. The wild form with single

flowers occurs here and there in the warmer parts of Europe,[986]

including Central and Southern Russia, and Greece; also in Asia Minor,

Armenia, Kurdistan, and the Caucasus. But the plant passes into so many

varieties, and has from a remote period been so widely cultivated, that

its distribution cannot be ascertained with any exactness. As a garden

plant it exists under a multitude of forms.

=History=—The use in medicine of the rose dates from a very remote

period. Theophrastus[987] speaks of roses being of many kinds,

including some with double flowers which were the most fragrant; and

he also alludes to their use in the healing art. Succeeding writers

of every age down to a recent period have discussed the virtues of

the rose,[988] which however is scarcely now admitted to possess any

special medicinal property.

[983] Johnston in his _Travels in Southern Abyssinia_ (1844), speaking

of koso, says its effects are “_dreadfully severe_.”—Even in Abyssinia,

he adds, it is barely tolerated, and if any other remedy equally

efficient for dislodging tapeworm were to be introduced, koso would be

soon abandoned.

One of the varieties of _R. gallica_ is the _Provins Rose_, so called

from having been long cultivated at Provins, a small town about 60

miles south-east of Paris, where it is said to have been introduced

from the East by Thibaut VI., Count of Champagne, on his return

from the Crusades, A.D. 1241. But it appears that he went then to

Navarre and in later times never resided in the Champagne. Be this as

it may, Provins became much celebrated not only for its dried rose

petals, but also for the conserve, syrup and honey of roses made

from them,—compositions which were regarded in the light of valuable

medicines.[989]

It is recorded that when, in A.D. 1310, Philippe de Marigny, archbishop

of Sens, made a solemn entry into Provins, he was presented by the

notables of the town with wine, spices, and _Conserve of Roses_; and

presents of dried roses and of the conserve were not considered beneath

the notice of Catherine de Medicis, and of Henry IV.[990]

We find that Charles Estienne, in 1536, mentions both the _Rosæ

purpureæ odoratissimæ_, which he says are called _Provinciales_, and

those known to the druggists as _incarnatæ_,—the latter we presume a

_pale_ rose.[991] _Rosæ rubeæ_ are named as an ingredient of various

compound medicines by Valerius Cordus.[992]

=Production=—The flowers are gathered while in bud and just before

expansion, and the petals are cut off near the base, leaving the paler

claws attached to the calyx. They are then carefully and rapidly dried

by the heat of a stove, and having been gently sifted to remove loose

stamens, are ready for sale. In some districts the petals are dried

entire, but the drug thus produced is not so nice.

In England, the Red Rose is cultivated at Mitcham, though now only to

the extent of about 10 acres. It is also grown for druggists’ use in

Oxfordshire and Derbyshire. At Mitcham, it is now called _Damask Rose_,

which is by no means a correct name. The English dried roses command a

high price.

There is a much more extensive cultivation of this rose on the

continent at Wassenaar and Noordwijk in Holland; in the vicinity of

Hamburg and Nuremberg in Germany, and in the villages round Paris and

Lyons. Roses are still, we believe, grown for medicinal use at Provins,

but are no longer held in great esteem.

There appears to be a considerable production of dried roses in Persia,

judging from the fact that in the year 1871-72, 1163 cwt. were exported

from the Persian Gulf to Bombay.[993]

=Description=—The petals adhere together loosely in the form of little

cones, or are more or less crumpled and separate. When well preserved,

they are crisp and dry, with a velvety surface of an intense purplish

crimson, a delicious rosy odour, and a mildly astringent taste. The

white basal portion of the petals should be nearly absent. For making

the confection, the petals are required in a fresh state.

=Chemical Composition=—Red rose petals impart to ether, without losing

their colour, a soft yellow substance, which is a mixture of a solid

fat and _Quercitrin_. Filhol has shown (1864) that it is the latter

body, and not tannic acid, of which the petals contain but a trace,

that produces the dark greenish precipitate with ferric salts. The same

chemist found in the petals 20 per cent. (?) of glucose which, together

with colouring matter and gallic acid, is extracted by alcohol after

exhaustion by ether. According to Rochleder (1867), the gallic acid in

red roses is accompanied by querci-tannic acid.

[989] Pomet, _Hist. des Drogues_, 1694, part i. 174-177, speaks of the

roses of Provins being “hautes en couleur, c’est à dire d’un rouge

noir, velouté ... très astringentes.”

The colouring matter which is so striking a constituent of the petals,

is according to Senier an acid, which appears to form crystallizable

salts with potassium and sodium.[994] An infusion of the petals is pale

red, but becomes immediately of a deep and brilliant crimson if we add

to it an acid, such as sulphuric, hydrochloric, acetic, oxalic, or

tartaric. An alkali changes the pale red, or the deep crimson in the

case of the acidulated infusion, to bright green.

=Uses=—An infusion of red rose petals, acidulated with sulphuric acid

and slightly sweetened, is a very common and agreeable vehicle for some

other medicines. The confection made by beating up the petals with

sugar, is also in use.
