The latest study found that high-purity ginger extractbone improves symptoms of knee pain in patients with arthritis.
Dr. K. C. Marcussen of the Narayana Institute in Wisconsin, USA, selected 247 patients with osteoarthritis with knee joint symptoms and randomly divided them into two groups. They were given ginger extract twice daily/day and placebo for 6 weeks.
The results showed that after treatment, the percentage of patients with significant improvement in standing pain in the treatment group was significantly higher than that in the placebo group (p=0.048), and the reduction in average pain during standing and walking was also significant in the treatment group (p=0.005 and p=0.016).
The researchers noted that the overall evaluation of patients in the treatment group was better than in the placebo group, and that the number of medical assistance required in the treatment group was less than that in the placebo group. However, there was no significant difference in quality of life between the two groups. The side effects of the gastrointestinal tract in the treatment group were also more common than in the placebo group, but most of the symptoms were mild.
Dr. Donald M. Marcus and Dr. Maria E. Suarez-Almazor of the University of Houston School of Medicine pointed out in the review that the efficacy of ginger in this study was limited and not long-lasting. Moreover, the use of standing pain as a primary evaluation indicator is not reliable because WOMAC is a typical commonly used indicator for evaluating the efficacy of osteoarthritis, and there is no significant difference in WOMAC results between the two groups in this study. Therefore, it is not appropriate to recommend ginger as a drug for the treatment of arthritis.
