Marrubium Vulgare, Linn, (Common Horehound). The whole 

 plant is officinal. Stimulant, diuretic and tonic — in large doses laxative : 

 a popular remedy in coughs, colds, and diseases of pulmonary organs, 

 in the form of expressed juice, syrup or candy. We have known se- 

 vere cases of chronic cough cured by the expressed juice taken in 

 warm new milk. 



BoraginacejE, Juss. — (The Borage Tribe.) 



Pulmonaria* Virginica, Linn., (Virginian Lungwort). As the 

 species of this plant are emollient and demulcent, and have enjoyed a 

 high reputation in pulmonary diseases, Dr. Griffith thinks they owe 

 their efficacy to a reliance on the doctrine of signatures, the leaves 

 having spots bearing some resemblance to the lungs. — The virg. is 

 astringent, and is much used in some parts of the country in coughs 

 and colds, and diseases of respiratory organs. 



LlTHOSPERMUMf OFFICINALE AND ArVENSE, LlllTl., (Gromwell, 



Stone- weed). The seeds have a greyish- white, pearly color, and a 

 stony hardness. Formerly much employed as lithontriptic, from the 

 supposed resemblance between the remedy and the complaint. Not 

 used at present. 



Symphytum:}: Officinale, Linn., (Common Comfrey). A highly- 

 mucilaginous plant, slightly astringent ; it resembles closely the mal- 

 low ; both contain an acid malate of Altheine. (Jour, de Pharm., xiii., 

 635.) A popular remedy in catarrh, diarrhoea, dysentery, etc. 



Cynoglossum§ Officinale, Linn. — (Hound's Tongue.) 



C. Virginicum, Linn., (Wild Comfrey). These plants have ano- 

 dyne, demulcent, and astringent properties, and are employed as local 

 applications to scrofulous sores, burns, tumors, sprains, etc. The Of- 

 ficinale contains an odorous principle, tannin, and several salts. Dr. 

 Griffith thinks the plant too much neglected. (Med. Botany, p. 500.) 



Convolvulus|| Panduratus, Linn., (Wild Potato Vine). Indige- 

 nous ; the root very large, 2 or 3 feet in length, about 3 inches thick, 

 branched at bottom, has a somewhat acrid taste. Feebly cathartic, 

 slightly diuretic, and useful in calculous complaints, and strangury ; 



* From the Latin pulmones, the lungs ; they having been a remedy for diseases 

 of this organ. 



t From lithos, a stone, and s per ma, seed, which are very hard, 

 t From the Greek symphyo, to grow together, in allusion to its healing qualities. 

 § From the Greek kyon, a dog, and glossa, a tongue, from the shape of the leaves 

 |) From the Latin convolvo, to entwine.
