  Purpose
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.

Condition Intervention Phase
Osteoarthritis Dietary Supplement: Myalgesin™ (celery seed extract, Boswellia serrata extract, Phellodendron extract) Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
