Safety / Precautions


  • This plant, of which there many species and varieties throughout the western hemisphere, is closely related to wormwood (ajenjo), with which it shares similar properties.
  • Estafiate seems to be safer than wormwood, at least as a tea for adults, but unfortunately there are no clinical trials to ensure its correct dose or safety.
  • In any case, treatment with this plant should not be prolonged, as the safety of long term use is presently unknown.
  • Estafiate contains some chemical compounds known as terpenes that could be toxic to the nervous system should the patient ingest very concentrated forms of the tea.
  • Estafiate tea should not be ingested by pregnant or lactating women, as well as by small children, especially those under 6 years of age.
  • Patients suffering from Parkinson’s’ disease or other neural disorders should likewise avoid it, just to be on the safe side.
