Turmeric or Onion

One of the numerous health advantages of turmeric is increased blood flow. Since ancient times, both Ayurvedic and traditional Chinese medicine have used turmeric to expand blood arteries and promote blood circulation. Curcumin, a chemical found in turmeric, has been shown in studies to aid improve nitric oxide production, reduce oxidative stress, and reduce inflammation. Taking 2,000 mg of curcumin daily for 12 weeks resulted in a 37% increase in forearm blood flow and a 36% increase in upper arm blood flow in a study of 39 participants.

Onions are high in flavonoid antioxidants, which are beneficial to heart health. When blood flow rises, this vegetable helps your arteries and veins enlarge, which promotes circulation. In a 30-day trial of 23 males, ingesting 4.3 grams of onion extract daily enhanced blood flow and arterial dilatation after meals considerably. Onions are also anti-inflammatory, which helps improve blood flow and heart health by lowering inflammation in veins and arteries.
