8. Powders.

These though more seldom, yet are sometimes given with success in a Cough, and pneumonic distempers.

Take of the tops of Ground-Ivy somewhat reddish, a sufficient quantity, bruised let them be form'd into a Cake, which dryed presently in the hot Sun, reduce into fine powder, and keep it in a glass. This Plant keeps its virtue with smell and taste longer than any either Conserves or Syrups, and greatly profits in a grievous and pertinacious cough. Take from ʒss. to a dram, in distill'd water, or pectoral decoction twice in a day.

After the same manner Powders of other pectoral Plants are prepared, and taken with benefit.

Take of Cup-moss or chin-cups ʒiij. milk of Sulphur ʒj. Sugar-candy ʒss. make a pow∣der; the dose from ℈j. to ʒss. twice in a day. This powder is given with great benefit to those labouring with a chin-cough.

Take of the flour of Brimstone, Olibanum, Ceruse of Antimony, of each ʒij. divide it into xii. parts, take one part in the morning, and another in the evening in a spoonfull of a convenient vchicle.
