Wormwood, also known as mugwort or absinthe, has been used since ancient times to treat indigestion and parasites. We once tried it when we felt a heavy stomach after eating, and even a small amount of its strong bitterness helped curb our appetite. However, it has a history of issues with hallucinogenic and addictive properties, so knowledge of safe use is essential. Here, we summarize its expected effects, specific intake methods, and precautions in an easy-to-understand manner.
What is Wormwood? Ingredients and History
Wormwood is a plant of the Asteraceae family native to Europe, also known as an ingredient in the alcoholic beverage absinthe. Its main components include lactones and terpenoids, and some species may contain artemisinin-based compounds. Recent research suggests antioxidant, anti-inflammatory, and antiparasitic effects, providing scientific backing for its traditional uses. However, thujone, a component, affects nerves at high doses, so excessive intake is dangerous.
Expected Effects and Evidence
Parasite Expulsion (Anthelmintic Effect)
Anthelmintic effects of wormwood have been reported in laboratory and animal studies, as well as human trials. For example, studies show effects against human roundworms and tapeworms, and reports against dwarf tapeworms (e.g., a 2018 study). However, it is more realistic to consider it as a supplementary treatment rather than a substitute for anthelmintic drugs.
Improvement of Digestive Symptoms
A double-blind study (2007) targeting Crohn's disease patients reported improvement in symptoms and reduction in steroid dosage with a herbal preparation containing wormwood. Traditionally, it is expected to promote stomach movement as a post-meal drink or bitters.
Other Possibilities
Reports also suggest antioxidant, anti-inflammatory, and even some antitumor activities, but the effects are not uniform as the components vary greatly depending on the type and extraction method.
How to Take and Safety Precautions
Main Methods of Intake
- Tea (short infusion of dried leaves) – Easiest. However, it is very bitter.
- Tincture (alcohol extract) – Important to manage dosage as components are concentrated.
- Supplements/Capsules – Choosing standardized extracts makes it easier to understand the components.
- Absinthe (alcohol) – A luxury item, not recommended for therapeutic purposes.
Who Should Avoid It / Side Effects
Due to the risk of neurological symptoms (convulsions and confusion) caused by thujone, people with epilepsy or a history of seizures should not use it. It should also be avoided during pregnancy and lactation, and is not recommended for children. There are also reports of liver damage and potential drug interactions, so those taking anticoagulants or drugs involved in liver metabolism should consult a doctor. Avoid long-term high-dose intake, and use short-term, low-dose as a basic rule.
Practical Advice for Safe Use
- Check the ingredient list and reliability of the manufacturer for commercial products.
- Follow the instructions for each product and do not overuse it on your own judgment.
- If you have serious symptoms of parasitic infection or indigestion, consult a medical institution first.
Summary
Wormwood has been used for digestion and parasite expulsion since ancient times, and recent research suggests some effectiveness (e.g., reports of Crohn's disease improvement and anthelmintic effects). However, risks such as neurotoxicity and liver damage due to thujone, and contraindications during pregnancy, are also clear. From our own experience, we felt that a small amount of herbal tea relieved digestive sluggishness, but we prioritize safety and limit its use to short periods. If you plan to incorporate wormwood into your daily routine, we strongly recommend checking the quality of the product and consulting a specialist if you have chronic diseases or are taking medication.
