Pinus Pumilio

Mountain or Mugho Pine. South East-Europe.

The source of the once-prized Hungarian balsam. Its essential oil, Pinol, by some called Pumiline, is the potent agent in the German "pine cure:" internally, 5 minims on sugar, and externally on flannel as a counter-irritant.

Pinus Pinaster gives in Southern France the dried resin called "Galipot" of the Codex. Pinus Larix, in Tyrol, gives Venice turpentine; P. balsamea, in N. America, Canada balsam; P. Picea, in central Europe, Strasbourg turpentine.

Pinus Sylvestris

Scotch Pine. North Europe.

Fir-wool oil and extract are made from its leaves, for rheumatism. Fir-wood is a fibrous substance, also prepared from the leaves, and used for wrapping the affected parts. Dose of oil, internally, 15 to 20 drops. The French use the leaf-buds called "Bourgeons de Sapin."

One of the sources of Turpentine and Resin.

Pitouri Or Pituri

Duboisia Hopwoodii, Queensland. N. 0. Scrophulariacecæ (some say A tropacecæ).

A powerful stimulant to the liver, and also an intestinal aperient; useful in bilious headaches. Dose, 1/4 to 1 grain. If perfectly pure, of a pale drab; generally prepared in commerce by the alum process, of various shades of greenish yellow: the yellow colour is considered due to the presence of berberine: the portion of the resin insoluble in ether is reported to have no purgative effect.
