These three important herbs all have a similar effect on blood clots, namely preventing them by inhibiting platelet aggregation. When blood platelets in healthy, undamaged blood vessels begin to clump together, it can cause blood clots and blockage in those parts of the body, resulting in pain, swelling, discoloration and a lack of blood flow. This can be very dangerous, and even deadly, if the clot moves into the heart, lungs or brain. Bilberry, turmeric and ginger are all able to prevent platelet clumping, thus boosting heart health and keeping your blood moving normally.
