Plain English Summary
Background and study aims
Osteoarthritis is a long-lasting disease that results from the inflammation of the joints, causing breakdown of the cartilage and bone. Typically, a combination of exercise, lifestyle changes and non-steroidal anti-inflammatory (NSAID) drugs are used to reduce the pain and stiffness of osteoarthritis. NSAIDs can have side effects. Curcumin is a substance found in turmeric (Curcuma longa) that has been used to treat diseases involving inflammation in Ayurvedic (traditional Indian) and traditional Chinese medicine. Indian frankincense (Boswellia serrata) is another herb used to treat inflammation in Ayurvedic medicine. This study aims to investigate whether Biocurpain, a combination of turmeric and Indian frankincense extracts, can reduce pain in people with osteoarthritis.
Who can participate?
Adults who have been diagnosed with knee osteoarthritis for at least 4 weeks.
What does the study involve?
Participants will be randomly allocated to one of three groups. The first group will take Biocurpain and NSAID ibuprofen or diclofenac by mouth twice daily for 4 weeks. The second group will take Biocurpain by mouth twice daily for 4 weeks. The third group will take ibuprofen or diclofenac by mouth twice daily for 4 weeks. Before the start of the trial, at 2 weeks and at 4 weeks, the participants will rate their pain level on a scale of 1 to 10.
What are the possible benefits and risks of participating?
The potential benefits are that the participants might experience quicker relief from pain caused by osteoarthritis. The potential risks are that the participant might experience side effects from the study medication.
Where is the study run from?
Bethesda Hospital and Panti Rapih Hospital, Yogyakarta (Indonesia)
When is the study starting and how long is it expected to run for?

The benefit and safety of Curcuma longa and Boswellia serrata for osteoarthritis pain
The combination of Curcuma longa and Boswellia serrata is as effective as NSAID treatment (ibuprofen or diclofenac) in treating arthritic pain with better safety profile.

Patient information sheet
No participant information sheet available.
This was a randomized controlled trial study for 4 weeks. Subjects were divided into 3 groups randomly:
1. Group I: combination of CB extract (Biocurpain; 350 mg of Curcuma longa and 150 mg Boswellia serrata) and NSAID (400 mg of ibuprofen or 50 mg of diclofenac sodium)
2. Group II: CB extract alone
3. Group III: NSAID alone.
Each medication was taken two times per day for 4 weeks.Twenty tablets of 500 mg paracetamol, as a rescue medication, was given to each subject and the remaining was counted at the last week. The degree of pain measured using visual analogue scale (VAS). Physician Global Assessment (PGA) was an instrument to measure the physicians’ satisfaction with medication. Any adverse event was monitored. The analysis is intention to treat based.
Primary outcome measure
Pain measured using a visual analogue scale (VAS) at baseline, 2 weeks and 4 weeks
Secondary outcome measures
Physicians’ satisfaction with medication measured using the Physician Global Assessment (PGA) at 2 and 4 weeks
