Epazote (Dysphania ambrosioides)

A taxonomy boundary behind the name epazote

Kew currently accepts Dysphania ambrosioides and also accepts D. anthelmintica as a separate species. Kew lists Chenopodium anthelminticum as a synonym under D. anthelmintica. The older CONABIO sheet for D. ambrosioides lists C. anthelminticum among its synonyms, so the source concepts do not match. Historical names should be kept with the publication that used them rather than silently combined.

The Putla thesis prints Teloxys ambrosioides alongside the local name epazote. That is a source-specific label in an Oaxaca household-garden study, not a guarantee that every plant sold or gathered as epazote matches the same species. This article concerns food-use records attributed to D. ambrosioides or to the source's printed Teloxys name; it is not a field-identification guide.

Mexican seasoning accounts

The UNAM study of household gardens in Putla, Oaxaca, records epazote as a condiment. Its appendix says stems and leaves are added as beans, quesadillas or sauces come to a boil; another table lists leaves added to different stews. These are regional food-use descriptions, not a complete formula: no measured amount, serving yield, ordered cooking schedule or storage instruction is supplied.

CONABIO describes the plant as widely used in Mexican cooking, while Prairie View A&M's Spanish specialty-crops sheet lists dried leaves, flowers and seeds as seasonings and fresh leaves for tea. That extension sheet is a separate source context, not a Mexico-specific household practice account. Neither source makes culinary leaf use evidence for a medicinal treatment or an essential-oil dose.

What the grower sheet does and does not say

Prairie View A&M describes direct sowing or transplanting and says seeds need light, while also recommending a shallow sowing depth of 0.2–0.6 cm. It reports germination in 7–21 days, well-drained soil at pH 5.2–8.3, and 15–35°C as an optimum germination range. These are the sheet's production values, not proven mature-plant heat limits or frost hardiness; the two seed-placement statements are retained as printed rather than reconciled into a new instruction.

The sheet mentions containers and indoor or greenhouse starts, late-spring or early-summer planting in its temperate context, water as needed, moderate feeding and leaf harvest. It gives no pot size, container yield, greenhouse setpoint, humidity target, mature photoperiod requirement, frost threshold or Mexico-specific seasonal calendar. Its harvest timing and pest list are production guidance, not a household growing trial.

Keep food leaves separate from oil and medicine

The Oaxaca entries concern stems or leaves used as seasoning during ordinary cooking. The oil-related literature cited in the research dossier was available only as an abstract during that earlier review, and it does not establish a dose or safety profile for culinary leaves. Concentrated oil, medicinal products and food seasoning are different evidence categories; this article provides no medicinal recommendation or oil-use method.

No complete source-batched recipe, validated preservation method, household storage life or dose-response assessment for the food uses was established. No safe gathered-plant identification procedure or region-specific collection rule was reviewed.

Research gaps

Kew's accepted-name treatment conflicts with the older CONABIO synonym list; the source concepts behind historical C. anthelminticum uses remain unresolved.

The UNAM food entries and PVAMU seasoning list do not supply a complete source-batched recipe with quantities, yield, cooking endpoint or storage guidance.

The seed-light and shallow-depth statements in the PVAMU sheet are not reconciled; no separate household or replicated local crop trial was inspected.

No mature-plant frost/heat threshold, household container size, greenhouse setpoint, food-leaf dose assessment, local collection rule or species identification guide was established.

Research status

The underlying plant account received a partial source review. Its review scope is described in the original plant article.
