Conventional allopathic medicines and lifestyle modifications still remain the backbone of hypertension management. What about alternative treatments, though? Well,in 2013, the American Heart Association came out with an official statement addressing this issue, published in the journal Hypertension. The statement runs about 59 pages, but I will try to summarize this statement's conclusion's addressing the efficacy of approaches like acupuncture, yoga, meditation, etc in treating high blood pressure. Please note that these conclusions apply only to treatment of high blood pressure, and not to other health/psychological benefits that may be derived from doing these activities.
It is notable that relaxation and meditation, though useful for many purposes, have not been found to impact high blood pressure. Many people find this surprising, possibly since high blood pressure also is known as “hypertension.” Because of this potentially misleading term, many people have assumed that high levels of stress or “tension” are a major cause of “hypertension,” or high blood pressure. This is not the case. High blood pressure is an essentially mechanical, and not psychological, problem.
5. Take apple cider vinegar. In addition to lowering blood pressure almost overnight, apple cider vinegar has a myriad of fringe benefits. Apple cider vinegar helps with indigestion, especially if you suffer from diarrhea. It also soothes sore throats, cures hiccups instantly, and lowers cholesterol. Most importantly, it helps with weight loss by improving metabolism and reducing water retention -- and a healthy weight is key to normalizing blood pressure.
I use a wrist cuff to measure my BP. I am consistently ( I mean every time) able to lower my BP by approximately twenty points, both values, from the initial reading. I do it with controlled breathing. I inhale deeply and hold it until it just begins to become uncomfortable, exhale slowly, and hold the exhale, until it becomes slightly uncomfortable, and then inhale slowly again, and hold it, repeating the process at least 3 times. Not only is the BP down, but the sensation is that of being physiologically calmer.
A healthy diet is the first step in regaining control of high blood pressure, but don’t let the term “diet” fool you.  This is a lifelong commitment to healthy eating.  Based on the approach known as the DASH diet (dietary approaches to stop hypertension), patients should focus on consuming lean protein, whole grains, fresh fruits and vegetables, legumes, and low-fat dairy.  By doing so, systolic blood pressure (the top number) could be reduced by as much as 14 points.  Of course, what isn’t included is nearly as important as what is when it comes to a healthy diet.  Those with high blood pressure should also focus on keeping salt and sugar intake to a minimum. 
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.
