The evidence in words
How much to take
Only certified PA-free standardized extract (e.g., 50–75 mg twice daily for migraine).
Timing & separation
There are no strict timing conflicts on record for Butterbur; consistency matters more than the exact hour for most goals.
Why the dose is what it is
Petasin compounds have anti-inflammatory and smooth-muscle effects relevant to migraine and allergy.
Bottom line
Genuinely effective for migraine and hay fever, but ONLY as a certified PA-free product — otherwise it can damage the liver.
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.
