There are two plants known as Jesuit tea or Jesuit's tea. The lesser-known Chenopodium ambrosioides, epazote or Jesuit's tea appears only on one stamp (see above); its Mexican origin or association with missionary orders gave rise to names like the Spanish té de los Jesuitas or the German Jesuitentee. Ilex paraguariensis, yerba maté or Jesuit tea is very well-known in South America, where the leaves are used to prepare the popular stimulating drink called yerba maté or maté. For many years the tea had been banned as pernicious, even under pain of excommunication, but eventually the ban was lifted. Jesuits recognized its energizing properties. When food was short, natives could subsist on maté and smaller quantities of food. So the Jesuits cultivated it and prepared a beverage that would later be known as Jesuit tea or "the elixir of the Jesuits." They may have gotten into the production of maté on their reductions to save the natives from the more destructive epidemic of alcoholism.

Around 1630 Spanish Jesuits in South America learned of the healing powers of the cinchona tree. Its bark cured malaria and reduced other fevers as well. Prejudice against the Jesuits and the drug they brought back to Europe kept Protestant Europeans, however, distrusted the Jesuits and thought the bark was a plot to kill them, so many continued to die from malaria until 1681. Two French scientists, Pierre Joseph Pelletier and Joseph Caventou, later identified the exact substance in the bark that was curative, an alkaloid called quinine from the native word for bark. Other alkaloids with curative powers have since been isolated. Other plants are also known as Jesuit's Bark: Iva frutescens, Iva frutescens oraria, Iva oraria.

Jesuits' nuts (Trapa natans), also known as Jesuit nuts, Jesuit's nuts, water chestnuts, or water caltrops, are indigenous throughout southern Europe and eastward into China. The species contains a single large seed with a sweet and edible embryo which abounds in starch. These seeds are ground and made into bread in parts of the south of Europe. When the Jesuits introduced the rosary in China, they made them from the seeds of an aquatic plant known as water caltrops, often mistaken for the water chestnut. Because of the use of these seeds in rosaries, they became known as Jesuits' nuts. Jesuits' nuts are used as an ingredient in many elaborate oriental recipes. Fresh Jesuit's nuts are available in September in areas with large oriental populations such as Hawaii and California. Oriental and specialty food stores carry boiled Jesuits' nuts year round in cans or jars, usually in a honey or sugar syrup.
