wormseed
C2 / Very Low FrequencyTechnical / Historical / Botanical
Definition
Meaning
The seed or dried parts of certain plants used historically to expel or treat intestinal worms.
A common name for several plants with anthelmintic (worm-expelling) properties, primarily in the genera Artemisia and Dysphania. It can also refer loosely to plants used similarly.
Linguistics
Semantic Notes
The term is a compound noun (worm + seed). Its meaning is highly specific and literal, referring to a physical botanical substance with a defined historical medicinal use. It has no modern figurative meanings.
Dialectal Variation
British vs American Usage
Differences
No significant difference in meaning. The specific plant referred to as 'American wormseed' (Dysphania ambrosioides, formerly Chenopodium ambrosioides) is native to the Americas, so the term may be more familiar in that botanical/regional context.
Connotations
In both varieties, the word is archaic in a medical context but remains a precise botanical/common name.
Frequency
Extremely rare in everyday language in both regions. Slightly higher frequency in historical texts, botanical guides, or discussions of traditional medicine.

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating literally as 'червячное семя'. The correct equivalent is the botanical/medical term 'цитварная полынь' (for Levant wormseed, Artemisia cina) or 'марь амброзиевидная' (for American wormseed). It refers to the whole plant or its parts, not just a seed.
Common Mistakes
- Using it as a verb (e.g., 'to wormseed something').
- Confusing it with 'wormwood' (a related but different bitter herb).
- Assuming it is a modern medical term.

Frequently Asked Questions
No. Wormseed oil, particularly from American wormseed, contains toxic compounds like ascaridole. Its use is dangerous without expert guidance and has been supplanted by safer, modern anthelmintics.
No. They are different plants, though both are in the Asteraceae family and have bitter, medicinal properties. Wormwood (Artemisia absinthium) is famous for absinthe, while wormseed (e.g., Artemisia cina) was used against parasites.
You might find it in some herbalist shops or online as a dried herb, often labeled as 'epazote' (for culinary use) or for historical/educational purposes. It is not a standard modern remedy.
The name originates from the use of the small, seed-like flower heads or fruits of certain species (like Levant wormseed) as the medicinal part. Over time, the name extended to the whole plant.
