What Natural Herbs Lower High Blood Pressure?

According to the American Heart Association, almost one in three adults has high blood pressure in the United States. Unfortunately, as many as one-third of those people don't realise they have high blood pressure, often because they do not have symptoms. Your doctor may recommend medication to lower your high blood pressure. In addition, there are alternative herbal remedies that may help to lower high blood pressure in a natural way. Consult with your physician before embarking on any herbal treatment program for high blood pressure.

Garlic and Onion

Garlic has properties that enable it to lower blood pressure. Like aspirin, garlic has blood-thinning abilities, and can lower both systolic and diastolic blood pressure readings.

Garlic contains d polysulfides, which enable the relaxation of blood vessels.

Incorporate garlic into your daily diet to reduce blood pressure readings. Just adding two cloves of garlic a day is enough to have an impact. Add garlic for four weeks to see results.

Another herbal remedy to treat high blood pressure is onion. Onions contain a component called quercetin that helps to relax blood vessels walls, thereby lowering blood pressure. This chemical has the property of being able to reduce the production of a blood vessel constricting element called angiotension II. It may also have the benefit of lowering cholesterol levels in the body.

Green Tea and Hawthorn

Green tea is commonly consumed in Japan and has been shown to lower blood pressure levels. It is important to consume green tea that is not caffeinated. Green tea contains an ingredient called catechins; in particular, EGCG, which limit ACE, an enzyme that perpetuates uncontrolled blood vessel constriction and causes blood pressure to rise. Regular consumption of decaffeinated green tea will lead to lower blood pressure readings.

The herb hawthorn has the ability to lower blood pressure by clearing out the arteries and improving blood flow throughout the body. It helps to improve circulation and makes the heart stronger. Take 300 mg three times daily to reduce blood pressure.

Stevia and Cinnamon

Stevia extract is derived from an herb that helps to lower blood pressure. Though often used as an alternative sweetener, stevia shows promise in lowering high blood pressure levels. A recommended dose is 250-500 mg of a standardised extract three times a day.

Cinnamon is a popular blood pressure-lowering spice. As little as one teaspoon a day can have a significant impact on lowering blood pressure levels.


Used in many countries such as China and Japan, cardamom is used for its medicinal properties, such as it ability to lower blood pressure. According to a study done by Aga Khan University in Pakistan, cardamom has qualities that lower blood pressure numbers significantly.


Flaxseed is another herbal alternative used to treat high blood pressure. Flaxseed and flaxseed oil both contain high levels of beneficial omega-3 fatty acids. Flaxseed works by balancing blood sugar levels, resulting in lower blood pressure. Ground flaxseeds can easily be added to your diet in baked goods, sprinkled on cereal or added to salads. A couple of teaspoons per day will yield good results.


Valerian is an herb that is traditionally used to treat insomnia. However, it is also a useful herb in treating high blood pressure because of its value as an overall relaxant. It has the ability to lessen anxiety, which can be one of the root causes of high blood pressure. Valerian is available in teas or supplements and is safe for daily use.

Avoid combining herbal remedies without consulting your physician. While herbal remedies offer an effective alternative to traditional medicine, work with your physician to determine the best treatment plan for dealing with high blood pressure.
