title: Mixture of Arnebia euchroma and Matricaria chamomilla (Marhame-Mafasel) for pain relief of osteoarthritis of the knee - a two-treatment, two-period crossover trial.
abstract: BACKGROUND
  Osteoarthritis is the most prevalent chronic non-infective joint arthritis. Because of its chronic disease nature, local drugs are preferred due to lower complications. In the present study, the new herbal pomade Marhame-Mafasel for knee osteoarthritis was used in a double-blind crossover trial. The aim of the study was to assess the efficacy and safety of Marhame-Mafasel pomade, which consists of several medical herbs including Arnebia euchroma and Matricaria chamomilla, in osteoarthritis of the knee.
  
  
  METHODS
  This study was a placebo-controlled double-blind crossover trial. Forty-two patients with pain associated with osteoarthritis of the knee (diagnosed by criteria of the European League against Rheumatism and physical examination) were drawn from patients attending the Clinic of Mostafa-Khomeini Hospital. In this study we assessed efficacy (analgesic effect and improved function) of herbal pomade Marhame-Mafasel, which was used locally in patients with primary osteoarthritis of the knee over three weeks. The instrument of the study was the Western Ontario and McMaster Universities (WOMAC) LK3.1 standard questionnaires.
  
  
  RESULTS
  The participants in each group were 21 patients; 30 (71.4%) were women and 12 (28.6%) of them were men. The participants were between 40 and 76 years old. Six patients had mild arthritis, 15 had moderate arthritis and 21 had severe arthritis. The positive analgesic effect of the herbal pomade Marhame-Mafasel in primary knee osteoarthritis was proven. The herbal joint pomade Marhame-Mafasel had a significantly greater mean change in score compared to the placebo group for osteoarthritis severity (p < 0.05).
  
  
  CONCLUSIONS
  Herbal pomade Marhame-Mafasel in comparison to placebo has more effect on reduction of pain of primary knee osteoarthritis.
