Prunellorum Silvestrium. Of Sloe-bush, or Sloe-tree. I think the college set this amongst the roots only for fashion sake, and I did it because they did.
Pyrethri Salivaris, &c. Pelitory of Spain. It is hot and dry in the fourth degree, chewed in the mouth, it draws away rheum in the tooth-ache; bruised and boiled in oil, it provokes sweat by unction; inwardly taken, they say it helps palsies and other cold effects in the brain and nerves.
Rhapontici, Rhupontick, or Rhubarb of Pontus. It takes away windiness and weakness of the stomach, sighings, sobbings, spittings of blood, diseases of the liver and spleen, rickets, &c. if you take a dram at a time it will purge a little, but bind much, and therefore fit for foul bodies that have fluxes.
Rhabarbari. Of Rhubarb. It gently purges choler from the stomach and liver, opens stoppings, withstands the dropsy, Hypocondriac Melancholly; a little boiling takes away the virtue of it, and therefore it is best given by infusion only; If your body be any thing strong, you may take two drams of it at a time being sliced thin and steeped all night in white wine, in the morning strain it out and drink the white wine; it purges but gently, it leaves a binding quality behind it, therefore dried a little by the fire and beaten into powder, it is usually given in fluxes.
Rhaphani, Domesticœ and Sylvestris. Of Raddishes, garden and wild. Garden Raddishes provoke urine, break the stone, and purge by urine exceedingly, yet breed very bad blood, are offensive to the stomach, and hard of digestion, hot and dry in quality. Wild, or Horse Raddishes, such as grow in ditches, are hotter and drier than the former, and more effectual.
Rhodie Rad. Rose Root. Stamped and applied to the head it mitigates the pains thereof, being somewhat cool in quality.
Rhabarbari Monachorum. Monks Rhubarb, or Bastard-Rhubarb, it also purges, and cleanses the blood, and opens obstructions of the liver.
Rubiæ tinctorum. Of Madder. It is both drying and binding, yet not without some opening quality, for it helps the yellow jaundice, and therefore opens obstructions of the liver and gall; it is given with good success, to such as have had bruises by falls, stops looseness, the hemorrhoids, and the menses.
Rusci. Of Knee-holly or Butchers-broom, or Bruscus. They are meanly hot and dry, provoke urine, break the stone, and help such as cannot evacuate urine freely. Use them like grass roots.
Sambuci. Of Elder. I know no wonders the root will do.
