Chenopodiacæ.

Goosefoot Family.

Chenopodium ambrosioides, L.

Nom. Vulg.—Alpasotes, Sp.-Fil.; Pasotis, Apasotis, Tag.; American Worm-seed, Mexican Tea, Eng.

Uses.—This plant is a native of Mexico. It has a peculiar, somewhat offensive odor and an acrid, aromatic taste due to an essential oil resembling peppermint (?). According to Padre Mercado, “When the seeds are taken with wine, sensation is so dulled that the drinker may be whipped without feeling the lashes, and even if put to the torment, does not feel it.” These properties, if true, make this plant one of the most useful in the Philippines. The entire plant is stimulant. The infusion, given internally, causes sweating, excites the circulation, is diuretic, tonic, stomachic, and useful as well as an antispasmodic in nervous troubles. The leaves are employed in making the infusion, 8 grams to 200 of boiling water. It is widely used in bronchial catarrhs and in asthma on account of its sudorific and expectorant action. It seems also to possess emmenagogue properties. The seeds yield on distillation a yellow essential oil with a strong and disagreeable odor, density 0.908. Both seeds and flowers are vermifuge, and are used as such in Brazil in doses of 8 grams in infusion or with an equal dose of castor oil. The anthelmintic dose of the essential oil is 5–15 drops with powdered sugar.

Rilliet and Barthez recommend the following potion for infantile chorea:

Leaves of chenopodium 4 grams.
Water 500 grams.

Make an infusion and add syrup of orange flowers 50 grams. Dose, several tablespoonfuls a day.
