A pilot study concluded that topical treatment with Sambucus ebulus L. (S. ebulus) gel can be advised for improving symptoms of patients with knee OA [17]. Jabbari et al. analyzed 79 patients with knee OA. They were randomly enrolled in two parallel arms of a pilot randomized, double-blind, active-controlled clinical trial. The patients were treated by topical S. ebulus gel or 1% diclofenac gel, three times a day, as much as a fingertip unit for 4 weeks. Patients were assessed prior to enrollment and, then, 2 and 4 weeks subsequent to the intervention, in terms of scores of VAS for self-grading of their knee joint pain, and according to three different domains of WOMAC questionnaire. Any observed adverse effects were also scrutinized. The mean values of WOMAC pain score, total WOMAC score, and VAS score for pain of the S. ebulus group were significantly lower compared with the diclofenac group. In addition, no serious adverse effect was reported.
