10 Herbs That May Help Lower High Blood Pressure
Healthline | By Healthline editorial team
Overview
Many adults around the world deal with hypertension, also called high blood pressure. Due to the recent changes in guidelines, nearly half of American adults will now be characterized as having high blood pressure. Experts recommend treating the condition with lifestyle changes and medications.
If you’re thinking of trying herbs for medical reasons, whether it’s the whole herb or a supplement, speak to your doctor first. Currently, there are no herbs regularly recommended by high blood pressure specialists. Some herbs, especially in large quantities, may produce undesirable side effects or interfere with other medications.
Read on to learn more about herbs and the research surrounding them.
1. Basil
Basil is a delicious herb that goes well in a variety of foods. It also might help lower your blood pressure. In rodents, basil extract has been shown to lower blood pressure, although only briefly. The chemical eugenol, which is found in basil, may block certain substances that tighten blood vessels. This may lead to a drop in blood pressure. More studies are needed.
Adding fresh basil to your diet is easy and certainly can’t hurt. Keep a small pot of the herb in your kitchen garden and add the fresh leaves to pastas, soups, salads, and casseroles.
2. Cinnamon
Cinnamon is another tasty seasoning that requires little effort to include in your daily diet, and it may bring your blood pressure numbers down. One study done in rodents suggested that cinnamon extract lowered both sudden-onset and prolonged high blood pressure. However, the extract was given intravenously. It’s unclear if cinnamon consumed orally is also effective.
You can include more cinnamon in your diet by sprinkling it on your breakfast cereal, oatmeal, and even in your coffee. At dinner, cinnamon enhances the flavor of stir-fries, curries, and stews.
3. Cardamom
Cardamom is a seasoning that comes from India and is often used in South Asian cuisine. A small study of 20 people investigating the health effects of cardamom found that participants with high blood pressure saw significant reductions in their blood pressure readings after taking 1.5 grams of cardamom powder twice a day for 12 weeks. You can include cardamom seeds or powder in spice rubs, soups and stews, and even baked goods for a special flavor and a possible positive health benefit.
4. Flax seed
Flax seed is rich in omega-3 fatty acids, and has been shown in some studies to lower blood pressure. A recent review suggested taking 30–50 grams of whole or ground seeds per day for more than 12 weeks to get the best benefits. Flax seed may protect against atherosclerotic cardiovascular disease by reducing serum cholesterol, improving glucose tolerance, and acting as an antioxidant.
You can buy many products that contain flax seed, but a better bet is to buy whole or ground flax seed and add it to your home-cooked meals. The best part about flax seed is that it can be stirred into virtually any dish, from soups to smoothies to baked goods. Storing flax seed in your freezer may help it retain optimum potency.
5. Garlic
This pungent seasoning can do more than just flavor your food and ruin your breath. Garlic may have the ability to lower your blood pressure by helping to increase a substance in the body known as nitric oxide, which can cause your blood vessels to relax and dilate. This lets blood flow more freely and reduces blood pressure.
You can add fresh garlic to a number of your favorite recipes. If the flavor is just too strong for you, roast the garlic first. And if you simply can’t eat the stuff, you can get garlic in supplement form.
6. Ginger
Ginger may help control blood pressure. In animal studies it has been shown to improve blood circulation and relax the muscles surrounding blood vessels, lowering blood pressure. Human studies so far have been inconclusive. Commonly used in Asian foods, ginger is a versatile ingredient that can also be added to sweets or beverages. Chop, mince, or grate fresh ginger into stir-fries, soups, and noodle or vegetable dishes, or add it to desserts or tea for a refreshing taste.
7. Hawthorn
Hawthorn is an herbal remedy for high blood pressure that has been used in traditional Chinese medicines for thousands of years. In rodents, extracts of hawthorn seem to have a whole host of benefits on cardiovascular health, including helping reduce blood pressure, preventing hardening of the arteries, and lowering cholesterol. You can take hawthorn as a pill, liquid extract, or tea.
8. Celery seed
Celery seed is an herb used to flavor soups, stews, casseroles, and other savory dishes. Celery has long been used to treat hypertension in China, and studies in rodents have shown that it may be effective. You can use the seeds, or you can juice the whole plant. Celery may also be a diuretic, which may help explain its effect on blood pressure. ResearchersTrusted Source believe that a variety of substances in celery may play a role in lowering blood pressure. However, human studies are needed.
9. French lavender
The beautiful, perfume-like scent of lavender is not the only useful aspect of the plant. Lavender extracts have been shown to lower heart rate and blood pressure in rodents. Although not many people think to use lavender as a culinary herb, you can use the flowers in baked goods. The leaves can be used in the same way you would use rosemary.
10. Cat’s claw
Cat’s claw is an herbal medicine used in traditional Chinese practice to treat hypertension as well as neurological health problems. Studies of cat’s claw as a treatment for hypertension in rodents indicate that it may be helpful in reducing blood pressure by acting on calcium channels in your cells. You can get cat’s claw in supplement form from many health food stores.
