Quick Summary

Epazote (Dysphania ambrosioides) is a medicinal plant traditionally used for various health issues, including as an anthelmintic and for gastrointestinal complaints. Scientific research includes phytochemical analyses and ethnobotanical studies; however, high-quality human clinical trials remain limited.

What is it?

Epazote is a herbaceous plant native to Central and South America. It has a distinctive strong aroma and has been used both as a culinary herb and in traditional medicine. The plant contains various bioactive compounds and is valued particularly in indigenous and folk medicinal systems.

Traditional Uses

Historically, Epazote has been used by indigenous communities, such as the Pataxó Hãhãhãi people of Brazil, to treat parasitic infections including worms, as well as conditions like diabetes and hypertension. It is also commonly used as a digestive aid and for other gastrointestinal complaints. These uses are based on traditional knowledge rather than controlled clinical trials.

Active Compounds

Epazote contains various phytochemical compounds, although detailed profiles vary. Some components studied in related plant species and extracts have shown antimicrobial and anti-inflammatory properties. Specific active compounds in Epazote contributing to these effects require further identification and clinical validation.

Potential Benefits with Evidence Levels

  • Helicobacter pylori eradication (Moderate evidence): A systematic review and meta-analysis (Zhao et al., 2022) found that a multi-herb product including components similar or related to Epazote increased Helicobacter pylori eradication rates when combined with conventional treatments after four weeks. However, human clinical studies focusing on Epazote alone are not available.
  • Antimicrobial effects (Preclinical evidence): Animal studies and preclinical research suggest that plant-derived extracts have anti-Helicobacter and anti-inflammatory effects (Chen et al., 2025). Some antimicrobial activity against oral bacteria has been observed in nanoparticles involving zinc oxide but not directly attributed to Epazote.
  • Traditional medicinal uses (Traditional/ethnobotanical evidence): Ethnobotanical studies document Epazote’s use among indigenous peoples for parasitic infections, diabetes, and hypertension (Pataxó Hãhãhãi people, Brazil). These uses are based on traditional practice, not on controlled trials.

Side Effects

There is limited systematic data on adverse effects of Epazote in humans. Some traditional usage patterns suggest caution due to potential toxicity; however, no clinical safety data are currently available to confirm these concerns.

Drug Interactions

No documented data on interactions between Epazote and pharmaceutical drugs were identified in the available literature.

Who Should Avoid It

Due to the lack of safety data, individuals who are pregnant or breastfeeding should exercise caution and consult healthcare providers before using Epazote. People with known allergies to plants in the same family or with underlying health conditions should also seek medical advice before use.

Evidence Limitations

  • Lack of randomized controlled trials specifically assessing Epazote’s efficacy and safety in humans.
  • Most existing data derive from traditional use or preclinical animal studies, which limits direct clinical applicability.
  • No high-quality clinical trials have assessed pharmacokinetics, optimal dosing, or long-term safety of Epazote.
  • Some observed effects are reported for herbal combinations containing Epazote-like plants, limiting attribution to Epazote alone.
