Ginger is a popular spice that has been used for centuries to treat a variety of ailments. Recent studies have shown that ginger can be an effective way to lower blood pressure and may even be as effective as some commonly used medications. Gingerol, a component of ginger, has been found to inhibit tumor growth in laboratory tests. Drinking ginger tea can also help improve heart health and reduce blood pressure.
In one study, participants reported relief after taking 400 milligrams of ginger extract along with nonsteroidal anti-inflammatory drugs. However, there are some concerns that ginger may interact with blood-thinning medications, such as warfarin, according to the National Center for Complementary and Integrative Health (NCCIH). If you are taking ginger supplements or drinking ginger tea, it is important to let your doctor know before having surgery or anesthesia. The objective of a recent systematic review and meta-analysis was to determine the efficacy of ginger supplementation on blood pressure (BP). The results showed that taking ginger extract can lower plasma cholesterol, inhibit LDL oxidation, and attenuate the development of atherosclerosis in atherosclerotic mice deficient in apolipoprotein E. Pregnant or breastfeeding women, people with heart problems, and people with diabetes should not take ginger without consulting their doctor. In another study of 261 people with knee osteoarthritis, those who took ginger extract twice a day felt less pain and needed less pain relievers than those who received a placebo.
Researchers also found that eating 2 grams of ginger a day reduced fasting blood sugar and other vital indicators of diabetes. A systematic review and meta-analysis of the effect and safety of ginger in the treatment of pregnancy-associated nausea and vomiting also showed that taking ginger extract can reduce the severity and duration of nausea, but not vomiting, during chemotherapy. Conventional prescription and over-the-counter medicines for nausea can also have side effects that ginger doesn't have, such as dry mouth and drowsiness. Finally, other studies suggest that ginger may help improve blood sugar control among people with type 2 diabetes. It is important to note that you should not drink ginger if you have a bleeding disorder or if you are taking blood-thinning medications, including aspirin. Talk to your doctor before taking ginger if you take blood thinners, such as warfarin (Coumadin), clopidogrel (Plavix), or aspirin.
