Tanacetum parthenium

Family: Asteraceae
Portuguese: Tanaceto, partenela, rainha-das-ervas

About: A small, aromatic, bushy perennial 10-60 cm high, with daisy-like flowerheads and strongly scented, lobed leaves. Historically known as "medieval aspirin" for its use in headaches, fevers, and pain.

Parts used: Flowering aerial parts — leaves and flowerheads, harvested at full bloom when parthenolide content is highest.

Traditional uses:

  • Fevers, headaches, migraines, and general pain

  • Rheumatoid arthritis, osteoarthritis, and joint pain

  • Stomach ache, indigestion, bloating, and intestinal worms

  • Menstrual cramps (with caution — emmenagogue properties)

  • Topical: toothache, insect bites, eczema, and psoriasis

Modern uses:

  • Migraine prevention: Standardized extracts taken daily over weeks can reduce attack frequency and severity in some individuals — one of the best-studied uses

  • Anti-inflammatory: Used for arthritis and musculoskeletal pain

  • Inhibits prostaglandins, leukotrienes, and thromboxanes

  • Research areas include anxiolytic, antimicrobial, and antitumor effects

Cautions: Not for use during pregnancy. May cause mouth ulcers when fresh leaves are chewed daily. Allergic reactions possible in those sensitive to Asteraceae.

Available in Our Apothecary

  • Dried herb (loose)

  • Feverfew tincture

  • Featured in our Headache Relief Blend
