What is uncertain

Read off the same rows as above. Nothing here is added that the entry does not itself record.

  • Thin evidence: Migraine frequency (grade C).

The evidence in words

What it is

Feverfew (Tanacetum parthenium) is standardized to parthenolide and used for migraine prophylaxis.

How it works

Anti-inflammatory and serotonin-modulating actions relevant to migraine pathophysiology.

What the evidence shows

Some trials show reduced migraine frequency, others are null; standardization varies. It is a reasonable second-line botanical, often paired with magnesium and riboflavin.

How to use it

Standardized extract (parthenolide) daily for prevention; give it 1–2 months.

Safety & interactions

Generally tolerated; mouth ulcers with raw leaf; mild antiplatelet effect; rebound headaches on abrupt stop. Magnesium — Common migraine-prevention stack.

Bottom line

A modest migraine-prevention option, best stacked with magnesium and riboflavin. Standardized product, give it a couple of months.

How it is used

As the entry records it, from the studies it summarises. Not a recommendation for you — doses that suit a trial population may not suit you.

Standard
Standardized parthenolide daily, 1–2 months.
