Flowers in inflorescences in clusters in dense spikes.
The fruits (utricles) are covered by the perigonium (greenish calyx), and inside are the seeds (achenes). Lenticular seeds, 0.7 – 1mm. in diameter, bright brown in color.
Components of epazote
- Essential oil (1% in the seeds and up to 0.5% in the whole plant): The essential oil of epazote, present throughout the plant (although more abundant in the seeds), contains toxic ingredients called terpene peroxides. These are ascaridol (64% of the essential oil), p-cimol and terpene carbides. It also contains safrole and saponins.
- Ascaridol is the active principle that gives the plant its anthelmintic properties. The Chenopodium ambrosioides anthelminticum subspecies is the most concentrated in ascaridol, and is considered medicinally more active.
