Abstract
Artemisia absinthium L., known as wormwood or absinthe, is a Eurasian plant adapted to all regions of Brazil. Traditionally, according to treatises from the 17th to 20th centuries, wormwood has been used for uterine disorders, to stimulate circulation, and to treat heartburn, digestive atony, and bladder ailments, using its leaves and flowering tops.
Preclinical studies have validated its uterotonic use, showing that the aqueous extract exerts a contractile effect on isolated rat uterus, reinforcing the abortive risk in pregnant women. Wormwood also showed efficacy in Polycystic Ovary Syndrome models, demonstrating hormonal regulatory and antioxidant effects. For digestive atony, the plant exhibited gastroprotective action, reducing gastric lesions due to its antioxidant properties. In bladder disorders, it showed nephroprotective effects, evidenced by decreased renal damage biomarkers in rats. In oncology, α,β-thujone and flavonoids demonstrated antineoplastic activity in cervical and endometrial cancer. The main compound, thujone, is neurotoxic at high doses and regulated by agencies such as EMA and EFSA, although standardized extracts show low toxicity in hepatic and brain tissues. Wormwood is included in the Brazilian Pharmacopoeia, the European Medicines Agency, and the National List of Medicinal Plants of Interest to the Brazilian Public Health System (RENISUS).
