Plantain Family. _Plantago erosa_, Wall. (_P. crenata_ and _media_, Blanco.) Nom. Vulg.--_Llantén_, Sp.-Fil.; _Lantín_, Tag.; _Plantain_, Eng. Uses.--The leaves of this popular plant are the commonest remedy in the Philippines for abscess of the gums. They are bruised and applied with a little lard over the swollen cheek. It is emollient and, in decoction, is used as a substitute for flaxseed. Botanical Description.--This plant is so universally known that there is no fear of confusing it with others. It flourishes as a common weed in the U. S. as well as the Philippines. NYCTAGINACEÆ. Four-O'Clock Family. _Mirabilis Jalapa_, L. (_M. longiflora_, Blanco.) Nom. Vulg.--_Maravillas_, _Suspiros_, Sp.-Fil.; _Gilalas_, Tag.; _Four O'Clock_, _Marvel of Peru_, Eng. Uses.--The root is purgative and possesses the same active principles, the same properties and is given in the same dose as jalap. According to the experience of Shoolbred, Hunter, W. O'Shaughnessy and Ainslie, its purgative action is weak and uncertain and therefore unworthy of use as a substitute for jalap. The bruised leaves are used as poultices to hasten suppuration, but according to Waring they are capable of causing dermatitis.
