Feverfew trials for rheumatoid arthritis

Twenty participants with rheumatoid arthritis were randomly selected to take one capsule containing 70–86 mg of powdered feverfew leaf, while the other 21 participants were randomly selected to take a placebo capsule daily for six weeks. Both treatment groups were asked to continue their usual medications.

  • No significant differences were found between the two groups in the clinical and laboratory presentation of the disease at the end of the treatment.
  • One patient in the treatment group reported minor ulcerations and a sore tongue.
