Epazote Nutrition facts

Epazote is a traditional Central American herb employed by native Mexicans since antiquity. Its strong, musky flavor gives a unique taste to Mexican and other Latin American cuisines. While its young shoots and tender leaves are used like leafy greens in soups; its mature, pungent leaves are added in small quantities as digestive and carminatives in bean, fish, and corn dishes.

Binomially, the herb belongs to the large Amaranthaceae family of herbs and vegetables, including amaranth, spinach, quinoa, beets, etc. Scientific name: Chenopodium ambrosioides. Some of the common names include wormseed, Mexican tea, pazote, etc.

Epazote is one of the most efficiently growing annual herbs. It prefers well-draining, sandy soil and full sunlight to flourish. The herb grows generously in the fields and on the roadside hedges as a weedy invasive plant. It reaches about 60 to 100 cm in height featuring small pointed leaves with serrated margins. Tiny yellow-green flowers appear in clusters as in amaranth, which develop subsequently into numerous small black seeds.

Health benefits of Epazote

Epazote has largely been viewed as a medicinal herb rather than a potherb. Normally its leaves are used in cooking to counter the indigestion and flatulence effects of foods prepared with protein-rich, high-fiber beans. Nonetheless, it has its own inherent phytonutrients, which when consumed in moderation, would contribute towards overall wellness.

  1. The herb is very low in calories. 100 grams of leaves carry just 32 calories. Its smooth leaves provide a good amount of fiber, 3.8 g per 100g.

  2. Its leaves are composed of many monoterpene compounds such as ascaridole (60-80%), iso-ascaridole, p-cymene, limonene, and terpinene. Ascaridole is toxic to several intestinal worms like roundworms, hookworms, pinworms, etc. Native Mayans drank its infusion regularly to keep off from worm infestation.

  3. The herb parts, especially young leaves are an excellent source of folic acid, providing 215 µg or 54% of daily recommended values. Folic acid is involved in the DNA synthesis and cell division.Caution note: Expectant mothers, however, should avoid epazote greens in their diet since it causes uterine cramps and possible risk of termination of pregnancy. (Medical disclaimer).

  4. Epazote has small amounts of vitamin-A and some flavonoid phenolic anti-oxidants such as beta-carotenes. Together, they act as protective scavengers against oxygen-derived free radicals and reactive oxygen species (ROS) that play a role in aging and various disease processes.

  5. The herb has a good amount of minerals like calcium (27% of RDA), manganese, potassium, iron, copper, zinc, and selenium. The body uses manganese as a co-factor for the antioxidant enzyme, superoxide dismutase.

  6. It has small but adequate levels of other B-complex vitamins, particularly pyridoxine and riboflavin. These vitamins function as co-factors in the enzymatic metabolism inside the body.
