Lamium. Lamium album. White Dead Nettle.

Botanical name: 

Lamium. Lamium album L. White Dead Nettle. (Fam. Labiatae.)—A perennial herb introduced from Europe and found on roadsides and waste places in the United States. Hemostyptic properties were long since attributed by Lusitanus and by Florain to the flowers of this plant, and, according to the more recent researches by Kalabin (Cb. G. T., xx. No. 12), their decoction produces a rise of the arterial pressure due to contraction of the peripheral vessels. The extract was found to cause firm, lasting contraction of the uterus, and the saturated tincture, in doses of twenty-five to forty minims (1.6-2.5 mils) every two or three hours, to be useful in hemorrhagic metritis and metrorrhagia. Its effects in puerperal hemorrhage were not pronounced.

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