Efficacy of Myalgesin™ to Support Joint Function in Patients With Knee Osteoarthritis

Status unconfirmed · Phase 3

Conditions studied: Osteoarthritis

In brief

Myalgesin is a botanical preparation consisting of celery seed extract,extract of dried Boswellia serrata, and dried extract of Phellodendron bark. Component of these extracts have been shown to exert anti-inflammatory effects and to inhibit cyclooxygenase and 5-lipooxygenase. The study is based on the hypothesis that oral administrration of this botanical will support joint function in people with osteoarthritis of the knee and improve symptoms and mobility as measured by the Western Ontario and McMaster Universities (WOMAC) Osteoarthritis Index.
