Turmeric
Turmeric is majorly used to enhance blood flow.
Ayurvedic and traditional Chinese medicine have used turmeric since ancient times to expand blood vessels and boost blood circulation.
Studies reveal that a compound seen in turmeric called curcumin helps increase the synthesis of nitric oxide, [3] decrease oxidative stress and reduce inflammation.
Consuming 2,000 mg of curcumin every day for 12 weeks can cause a 37% increase in forearm blood flow and a 36% increase in upper arm blood flow.
Leafy Greens
Leafy greens such as spinach and collard greens have high amounts of nitrates, which your body changes into nitric oxide, an effective vasodilator.
Having a nitrate-rich diet can boost circulation by expanding blood vessels, allowing your blood to flow more easily.
Research reveals that consuming high-nitrate (845 mg) spinach daily could lead to great improvement in blood pressure and blood flow compared to a control group.
Research has also shown that people following a traditional Chinese diet high in nitrate-rich vegetables like Chinese cabbage can lower blood pressure and a significantly decreased risk of heart disease than those who consume popular Western diets.
