Turmeric is a beautiful golden spice used medicinally in India for over 4,000 years. Curcumin, the main active ingredient in turmeric, has been extensively studied for its potential to reduce oxidative stress and support a healthy inflammatory response. Studies suggest that curcumin may be particularly beneficial for people dealing with arthritic conditions and joint issues. Curcumin also may have cardioprotective effects: studies have examined how curcumin may be associated with reduced triglycerides and LDL cholesterol.
