Conserve of Red Roses.
Take a pound of red rose buds, cleared of their heels; beat them well in a mortar, and, adding by degrees two pounds of double refined sugar, in powder, make a conserve.
After the same manner are prepared the conserves of orange-peel, rosemary flowers, sea- wormwood, of the leaves of wood-sorrel, &c.
The conserve of roses is one of the most agreeable and useful preparations belonging to this class. A drachm or two of it, dissolved in warm milk, is ordered to be given as a gentle restringent in weakness of the stomach, and likewise in phthisical coughs, and spitting of blood. To have any considerable effects, however, it must be taken in larger quantities.
