Botanical name: 

(A lot of the Boraginaceae contain toxic pyrrolizidine alkaloids. These alkaloids were unknown when this book was written. More info here: Livertoxic PAs --Henriette.)

Borago. Borago officinalis, L. Borage. Bourrache, Fr. Borasch, Boretsch, G. (Fam. Boraginaceae.)—This European annual abounds in mucilage, and the stems and leaves contain potassium nitrate with other salts. To these constituents the plant owes its feeble medicinal properties. An infusion of the leaves and flowers is employed as a demulcent, refrigerant, and gently diaphoretic drink. The expressed juice of the stems and leaves is also given in the dose of from two to four fluidounces (60-120 mils).

The Dispensatory of the United States of America, 1918, was edited by Joseph P. Remington, Horatio C. Wood and others.
