Researchers found that a turmeric extract that was free of essential oils most closely matched turmeric in commercial supplements. The extract which contains curcumin, appeared to be effective at blocking rheumatoid arthritis in rats by preventing a protein (known as NF-KB) from being activated in the joints. Activation of NF-KB has been associated with increased inflammation. The extract also blocked a pathway associated with bone loss, indicating there may be benefit for osteoporosis. Analysts recommend the results be viewed with caution. At this point, it is not recommended that patients alter their diets to include more turmeric. Clinical trials are needed before turmeric can be recommended for medicinal use.
