Feverfew (tanacetum parthenium)
This herb is used primarily in the treatment of headache and migraine. It helps with pain during an attack and also can be used as a preventative treatment. It is also a valuable tool in the treatment of psoriasis, arthritis, anaemia, tinnitus and vertigo.
It works by having anti-inflammatory, vasodilating and muscle relaxant properties which are common problems associated with severe headache.
