An Andrographis paniculata supplementation reduces joint pain in patients with knee osteoarthritis.

The aim of this double-blinded, randomized and placebo-controlled study was to examine the effects of an Andrographis paniculata extract in patients with knee osteoarthritis. 103 patients have been enrolled and received a placebo of the extract (ParActin®, 300 or 600 mg/day) for 84 days.

The both doses of supplement have reduced joint pain at days 28, 56 and 84 in comparison to control. Moreover, significant improvements in WOMAC stiffness scores and function scores, as in fatigue score have been measured in both supplemented groups compared to placebo. Finally, quality of life, assessed by the SF-36 questionnaire, and the score of the Functional Assessment of Chronic Illness Therapy have been improved in both supplemented groups.

In conclusion, this study shows that ParActin®, an Andrographis paniculata extract, can reduce joint pain and improve joint function in patients with knee osteoarthritis.
