Existing scientific evidence has shown that ginger has a normalizing effect on the circulation. It is believed to improve circulation by enhancing the body's ability to grow new blood vessels. However, better evidence is needed to confirm the results on this herb. If you want to try ginger, talk to your doctor first.
Ginger and Platelet Adhesion
According to American herbalist Rosemary Gladstar, ginger improves blood circulation by dilating blood vessels and reducing platelet aggregation, the process by which platelets -- small, membrane-bound packets of cytoplasm -- adhere to the vessel walls. Maintaining fluidity of blood in circulation is extremely necessary. Platelet adhesion can occur because of slower movement of blood, which, in turn, can block arteries, resulting in a heart attack or stroke.
Ginger and Peripheral Vascular Disease
Cholesterol buildup inside the leg arteries can interfere with circulation; you may develop peripheral vascular disease. Hard plaque can narrow and thicken the passage where blood flows. Ginger has shown promise in lowering cholesterol levels and, therefore, may improve blood flow to the lower legs and feet, says Phyllis A. Balch, author of the book "Prescription for Herbal Healing."
Other Health Benefits
Cancer patients who undergo chemotherapy often experience nausea and vomiting. Some people find taking ginger is useful in alleviating nausea and vomiting caused by chemotherapy because it increases gastrointestinal motility and transport. However, studies in this area report mixed results. As an anti-inflammatory agent, ginger may also be used to alleviate arthritis pain.
Side Effects
As with any therapy, always consult a physician or pharmacist before taking ginger as an herbal remedy. Side effects due to ginger are rare when used as recommended. However, not enough research has been done to know if ginger is safe for pregnant or breastfeeding women. Ginger acts as a mild blood thinner. It may increase the risk of bleeding when taken with warfarin and other anticoagulant drugs. People with blood-clotting disorders should also avoid ginger due to its ability to prolong bleeding time.
