I totally agree with you that we should not rely on medication for high blood pressure. End of the day, high blood pressure is a symptom that our body requires immediate attention. The kidneys work extremely hard to send out the “signal” to us and what we did is to pop a high blood pressure pill to suppress the signal. With this medication, our body has to work even harder to send us another signal. No wonder over the long run people who are suffering from high blood pressure needs an additional pill for deteriorating kidneys. Our body is fully capable of healing itself without us realizing it. I strongly encourage high blood pressure sufferers to listen to this and say goodbye to high blood pressure once and for all:

As much as I want, these alternative therapies do not replace traditional approaches for blood pressure control (low salt diet, medications). The best way to look at them is as strategies to complement what your doctor has already been prescribing you for your high blood pressure. This could really help if you have mild hypertension, where alternative therapies could potentially help you get off your blood pressure medications, but I highly doubt anyone with severe hypertension is getting off their Norvasc just because they started doing transcendental meditation. 
Sipping on not one but four cups of tea daily can help control blood pressure. A study presented at the European Society of Hyper tension in Milan found those who avoided coffee and tea consumption all together had the highest rates of blood pressure, pulse pressure, and heart rate. Those who drank tea the most often, between one to four cups a day, had the lowest systolic and diastolic blood pressure readings, as well as the lowest pulse pressure and heart rate. Pinkies up, for your blood pressure’s sake.
Enjoy a nice, sunny day and go for a brisk walk, for aerobic physical activity at least 30 minutes per day. Kennedy believes this "can decrease systolic blood pressure by 4-9 points." However, even "ten minutes a day can make all the difference." When blood pressure isn’t controlled, general isometric exercise is bad. Preferred cardiovascular exercises include: walking, running, cycling, and swimming.
There are other reasons you may want to spend more time in the great outdoors, though. A 2014 study found that when the skin is exposed to sunlight, a chemical reaction causes blood vessels to widen and blood pressure to drop. And in a 2010 study, people who spent time in nature—walking in the forest as opposed to in an urban environment—saw greater reductions in their blood pressure, pulse rate, and stress hormones.
“Weight is one of the most important determiners of blood pressure,” says John Bisognano, MD, director of the Hypertension Clinic at the University of Rochester Medical Center in Rochester, New York. “Once someone’s BMI is over 25 to 28, taking off a few pounds will make a big difference in treating high blood pressure.” (A body mass index of 25 to 29.9 is considered overweight, while 30 and higher is obese.) 
You can lower your systolic blood pressure (the top number) by switching to the DASH diet. The DASH diet is based on 2,000 calories a day. It's rich in fruits, vegetables, and low-fat dairy products. It's also low in saturated fat, cholesterol, and total fat. According to studies, adopting a DASH diet can reduce systolic blood pressure by eight to 14 points. The goal is to keep you blood pressure goal is less than 120/80.  
This technique is known to surprisingly few health professionals, though it has proved valuable in the treatment of a wide variety of health problems. Recently, this powerful technique has been shown to be an extremely effective method for allowing the body to rapidly normalize high blood pressure more effectively than any other treatment reported in the scientific literature.
Sleep. Short and poor-quality sleep are both associated with raised blood pressure (40). On the other side of the spectrum, excessively long sleep may also be harmful. One study found increased blood pressure in those who got fewer than five hours of sleep per night and in those who averaged more than nine hours of sleep per night, when compared with people who slept around seven hours (41). I suspect that it’s not the long sleep itself that is the problem, but that some underlying condition is both increasing sleep requirement and raising blood pressure.
