74. Potentilla Canadensis. Five finger. The above are mild 

 astringents, and have a bitterish, sweetish taste. They were for-

 mentilla.

Agrimonia eupatoria. Common agrimony. Sec. Celebrated as 

 a vermifuge; also used in decoction as an astringent gargle and 

 lotion. A common ingredient in "herb teas." Lindley. It has 

 been used in diseases of the genital organs, according to Alibert, 

 and Pallas says it has been employed in Russia, as a remedy for 

 worms in domestic animals. The Cyclopedia of Practical Medicine 

 says it is employed in the materia medica of the Indians, who use 

 it as a febrifuge; and Kalm says the Canadians use it in the same 

 manner, and for the same purposes. Its virtues reside in an essen- 

 tial oil, which turns black with the salts of iron.

Fragaria vesca. Common strawberries were used medicinally in 

 the days of Hoffmann and Linnaeus, and have been considered useful 

 in consumption, gout, scurvy, and gravel. They are considered re- 

 frigerant, diaphoretic, pectoral, and astringent. Infused in water, 

 they have the property of curing chilblains, when washed by it. 

 The roots are tonic, astringent, and bitter. They contain tannin 

 and gallic acid, and are good in diarrhoea, hemorrhages, &c. A 

 popular remedy in dysentery, according to the newspapers, is to 

 chew the whole plant and swallow it.
