Led by Shuba Singhal, PhD, this randomized, controlled clinical study was conducted at the Department of Orthopedics of Lok Nayak Jai Prakash Hospital/Maulana Azad Medical College, New Delhi. For the study, 193 patients diagnosed with osteoarthritis of the knee were randomized to receive either turmeric extract (BCM-95) as a 500 mg capsule two times daily, or a 650 mg tablet of paracetamol three times daily for six weeks.

Knee arthritis symptoms of pain, joint stiffness, and diminished physical function were evaluated using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). After six weeks of treatment, responder analysis showed significant improvement in WOMAC scores across all parameters comparable to the paracetamol group, with 18% of the BCM-95 group reporting 50% improvement, and 3% of subjects noting 70% improvement.

“We are learning more about the mechanisms behind curcumin’s anti-inflammatory effect which we believe is a result of its ability to inhibit pro-inflammatory signals, such as prostaglandins, leukotrienes, and cyclooxygenase-2. In addition, curcumin has been demonstrated to suppress several pro-inflammatory cytokines and mediators of their release, such as tumor necrosis factor-α (TNF-α), IL-1, IL-8, and nitric oxide synthase,”said Antony.
