What does the evidence tell us?
Some studies of turmeric or curcumin suggest improvements in knee-osteoarthritis symptoms, but higher-quality evidence is needed. Results from a concentrated extract cannot automatically be applied to ordinary root powder.

Digestive effects can occur. Liver injury has been reported with some highly absorbable curcumin products. Stop use and seek care for jaundice or dark urine, and check suitability with medicines or liver conditions.
