Dysphania ambrosioides, formerly Chenopodium ambrosioides, known as wormseed, Jesuit's tea, Mexican-tea,payqu (paico), epazote, or herba sancti Mariæ, is an annual or short-lived perennial herb native to Central America, South America, and southern Mexico.

D. ambrosioides is an annual or short-lived perennial plant (herb), growing to 1.2 m (3.9 ft) tall, irregularly branched, with oblong-lanceolate leaves up to 12 cm (4.7 in) long. The flowers are small and green, produced in a branched panicle at the apex of the stem.

As well as in its native areas, it is grown in warm temperate to subtropical areas of Europe and the United States (Missouri, New England, Eastern United States), sometimes becoming an invasive weed.

The generic name Dysphania traditionally was applied in the 1930s to some species endemic to Australia. Placement and rank of this taxon have ranged from a mere section in Chenopodium to the sole genus of a separate family Dysphaniaceae, or a representative of Illicebraceae. The close affinity of Dysphania to "glandular" species of Chenopodium sensu lato is now evident.

The common Spanish name, epazote (sometimes spelled and pronounced ipasote or ypasote), is derived from Nahuatl: epazōtl (pronounced [eˈpasoːt͡ɬ]) meaning skunk sweat.
