The use of herbs to lower high blood pressure has been in practice for thousands of years, due to the diverse range of effects that herbal remedies can have. High blood pressure is of two types – primary hypertension and secondary hypertension. There is no clear cause for primary hypertension, although it tends to occur more often as we age, and can be exacerbated by certain factors, such as a poor diet, smoking or a sedentary lifestyle. Secondary hypertension, on the other hand, can result in a more rapid and intense elevation of your blood pressure, but this has been linked to certain drugs and medical conditions, including kidney and thyroid issues, drug and alcohol abuse, birth control pills, obstructive sleep apnea, certain decongestants and pain relievers, among others.
High blood pressure is a serious health concern that should be mitigated or addressed in the right way. That extra tension or stress on your arteries and blood vessels can cause breakdown in these tissues, raising your risk of cardiovascular diseases and other complications. While lifestyle and dietary changes are highly recommended, there are also a number of herbal remedies that can reduce high blood pressure, thanks to their anti-inflammatory, anxiolytic, sedative and antioxidant properties.
