Overview

*Tanacetum parthenium*, a perennial herb in the Asteraceae family, is native to the Balkan Peninsula and cultivated globally. Characterized by daisy-like flowers and bitter leaves, it was traditionally used for fevers and pain. Its primary modern use is for migraine prevention. The key active compounds are sesquiterpene lactones, mainly parthenolide, which provide anti-inflammatory and vascular-regulating effects central to its medicinal efficacy.

Preparation Methods

For an infusion (tea), steep 1-2 tsp (1-2g) of dried leaves/flowers in 250 ml (8 oz) of boiling water. Cover for 10-15 minutes to retain volatile oils, then strain. For a tincture, combine 1 part dried herb with 5 parts 40-60% alcohol (1:5 ratio). Shake daily for 4-6 weeks, then strain. The recommended daily dose of dried herb is 50-250 mg, or 125 mg of a standardized preparation.

Usage & Dosage

For migraine prophylaxis, take 100-125 mg of dried leaf powder or a standardized extract (0.2% parthenolide) once daily. It is a preventative, requiring long-term, consistent use (several months), not for acute treatment. Tincture dosage is 1-4 mL, 2-3 times daily. Do not exceed 200 mg of dried herb daily. Discontinuation must be gradual to avoid rebound headaches.

Safety & Precautions

Side effects include mouth ulcers and digestive upset (nausea, diarrhea), especially from fresh leaves. Avoid if pregnant or breastfeeding (potential uterine contractions). It interacts with blood-thinning medications (anticoagulants) and NSAIDs, increasing bleeding risk. Avoid if allergic to the Asteraceae family (daisies, ragweed). Gradual discontinuation is essential to prevent 'post-feverfew syndrome'.
