One of the most extensively used herbs in traditional Persian medicine (TPM) used in the treatment of gastrointestinal (GI) disorders, is the plant Artemisia absinthium Linn. (AAL). It also has a wide range of activities such as analgesic and anti-inflammatory, anti-oxidant, anti-fungal, and anti-bacterial activities, hepatoprotective, and neuroprotective activities in addition to having gastroprotective effects. This article is a review comparing TPM resources with new medicines. This review investigates this herb in major TPM sources and strives to extrapolate the exact function it serves in the digestive tract and compares the collected information on the function of AAL with information found in new medical resource databases such as ISI, Pubmed, Scopus, Google Scholar, and Scientific Information Database. AAL from the Asteraceae family of TPM, known as Afsentin, was used in the treatment of GI weaknesses, stomach pains, swellings, intestinal parasites, diarrhea, and vomiting. AAL increased appetite, so it was used for insect repellents and insecticide. Recent studies have indicated that the effects of this plant improved the symptoms of Crohn's disease and played a role in reducing inflammatory factors. It also has strong anti-parasitic, anti-insect, hepatoprotective, and antioxidant effects. Given the widespread use of AAL as a traditional medicine currently in use in different countries, particularly in the treatment of GI diseases, further clinical studies that focus on the therapeutic qualities of this plant are required in the future.
