The blood pressure is the force, with which blood presses into the vessel walls, being pushed by the heart. When the vessels are clean and elastic and the blood is not to thin and not too thick, even big amounts of blood can be pushed through the them easily. Neither the heart nor the vessels are harmed.
In case the vessels are clogged or the blood is too thick or there’s excess of fluid in the body, it becomes tougher for the heart to push the blood.
That’s why it’s necessary to control blood pressure level, eat less salt and fat, do physical exercises and avoid obesity. However, in case there’s something wrong in other systems of the body and the excess of salt is not withdrawn properly, there will be a big imbalance. At this moment, the potassium in bitter leaf can help a lot. All our cells function well when there’s a proper balance between potassium and sodium.
This is how bitter leaf can help the body fight high blood pressure. Can it help in other cases, when the increase of blood pressure is caused by other things like stress, vessel spasms, and so on? It’s potentially effective for many cases with high blood pressure. The alkaloids the plant contains in its leaves is able to treat stress effectively and thus reduce the pressure significantly.
Of course, you should understand that if you are suffering from high blood pressure that reaches dangerous levels and you need a remedy that can work as emergency in a critical situation, bitter leaf is not what you should use, you should consult your doctor and go to the hospital for regular checkups.
At the same time, if you choose an herbal treatment, you need to realize that it will last longer because the effect of such remedies becomes visible only in several weeks. However, it will also last for a longer time than the effect of synthetic medical means.
How can I cure high pressure with bitter leaf?
If you are strongly into the treatment with the help of bitter leaf, here’s a recipe that may work for you:
– Take one handful of fresh bitter leaves (they need to be fresh; otherwise, there will be no effect)
– Take three cups of clean water
It’s possible to add some basil to the bitter leaves. It will increase the positive effect of the bitter leaf mixture because it’s able to regulate the level of cholesterol and glucose in your blood. So, when you’ve chosen the content of the plant part of the remedy, you need to set the water boiling and add the leaves exactly when it’s boiling. The high temperature will make sure that your liver will not be damaged by the mixture.
When you’ve cooked the mixture, don’t even think of drinking it straight away. You need to wash away the very first bitter water layer; otherwise, the acids it contains in galore will cause a serious damage to your health.
Sometimes, it’s also recommended to add milk to bitter water. It’s the matter of your taste because some people can’t stand the taste of the pure mixture and others can’t force themselves to drink the bitter milk. However, the treatment course is not so long to fail to stand the taste. You only need to have two cups of the mixture two times a week for only two weeks.
