Dog-Rose, the Common; Wild-briar; or Hep-tree, Rosa canina, L. an indigenous plant, growing in woods and hedges : in the month of June it bears oval flowers, which are succeeded by red, egg-shaped berries.
The blossoms of this plant, when distilled, afford a pleasant perfumed water. The leaves of every species of the rose, but especially those of the dog-rose, are recommended as a substitute for tea: when dried and infused in boiling water, they yield a fine colour, a somewhat astringent taste, and a grateful odour. - Dr. Gleditsch observes, that the green rose-leaves of every species are useful in currying fine leather.
An infusion of the full-blown blossoms of all the roses, especially of the paler kinds, is purgative ; but the petals of red roses, gathered and dried before they expand, become astringent. The bark of the dog-rose, according to M. Sie-fert, imparts to wool a dark brown colour, which was fixed in different specimens, by the usual ingredients; and on dropping into the dye a solution of alum, it changed into an azure blue. But he observes that, in all these experi ments, the colours possessed little or no lustre.
The berries of this shrub are at present chiefly employed in Britain by the apothecary, for making the conserve of heps. - On account of its fine flavour, the pulp of these berries is likewise used by the house-wife, in the north of Europe, for the preparation of domestic wines, with the addition of sugar. In a dried state, this pulp affords a grateful and rich ingredient in sauces. But we conceive that still greater advantage may be derived from dog-herries. by submitting them to the processes of fermentation and subsequent distillation. From an experiment we carefully made last autumn, it appeared that one gallon of this fruit, without any admixture, but that of a little water, yielded about two pints of .first runnings, which, after being distilled a second time, produced one pint of a very pure proof spirit.
