Migraine: the herbs with real prophylaxis trials

Butterbur, feverfew, riboflavin and magnesium all have trial evidence. Butterbur also has a liver warning and a supply problem.

remedy

Migraine prophylaxis has an unusual concentration of plant and nutrient evidence, and all of it is modest: a reduction in attack frequency of roughly one attack a month over placebo in the better trials. For someone having six attacks a month that is worth having; for someone having two it is marginal.

Butterbur (Petasites hybridus) has the best trial evidence of the herbs for migraine prophylaxis, in a randomised trial using a standardised extract. It also has a serious problem: the plant naturally contains pyrrolizidine alkaloids, hepatotoxic and carcinogenic, and only extracts certified as PA-free are acceptable. Reports of liver injury, along with supply and regulatory problems, mean the correct advice is: if you use it, use only a PA-free certified product, and discuss it with a clinician given that several better-studied prescription options exist.

Feverfew has multiple trials, of mixed and generally modest quality, showing a reduction in attack frequency and severity. Its active is parthenolide, a sesquiterpene lactone, whose concentration in a given leaf varies a great deal. Feverfew commonly causes mouth ulcers and GI upset, and stopping it abruptly can cause rebound headache.

Riboflavin (vitamin B2), at high dose (400 mg daily in the trials), reduces migraine frequency and is very safe. It is the easiest recommendation on this page because of the safety profile.

Magnesium has trials showing modest prophylaxis benefit at around 400-600 mg daily. Note that this is a different indication from muscle cramp, where the trials were negative — the same mineral, two different evidence bases.

Coenzyme Q10 has small trials with a positive signal. Ginger has small trials for acute migraine treatment, taken at onset.

What has the best evidence of all is not on this list: prescription prophylaxis (propranolol, topiramate, amitriptyline, and the CGRP monoclonal antibodies), acute treatment with a triptan or an NSAID, and trigger management including sleep regularity and caffeine consistency. A person with frequent or disabling migraine should be managed by a clinician, and the herbs here are additions to that conversation.

Preparation

Riboflavin (the safest option)

  • 400 mg daily, in divided doses with food if it causes nausea
  • Turns urine bright yellow — harmless
  • Allow 3 months before judging

Magnesium

  • 400-600 mg daily of magnesium citrate or glycinate; citrate is better absorbed but looser
  • Do not use in kidney impairment
  • Allow 2-3 months

Feverfew

  • Dried leaf, traditionally 50-150 mg daily of the leaf, or a standardised parthenolide extract
  • Chewing fresh leaf causes mouth ulcers; take capsules or a tea
  • Do not stop abruptly — taper, to avoid rebound headache
  • Not in pregnancy

Butterbur

  • Only a PA-free certified extract. The plant contains hepatotoxic pyrrolizidine alkaloids.
  • Standardised extract, 50-75 mg twice daily in the trial
  • Discuss with a clinician: liver injury has been reported, and prescription options have better evidence

Coenzyme Q10

  • 100 mg three times daily in the trials
  • Mild, safe, modest effect

Ginger for an attack

  • 250-500 mg powdered ginger at onset, or a strong ginger tea
  • Small trials show benefit; safe

The interventions with the most evidence

  • Regular sleep and meal times; consistent caffeine, neither a lot nor none
  • An attack diary, which identifies personal triggers better than any list
  • Acute treatment prescribed early, and prophylaxis if attacks are frequent
  • A headache diary before and during any new treatment, for 3 months
