Lemons
Lemons help keep blood vessels soft and pliable and by removing any rigidity, high blood pressure will be reduced. In addition, you can help lower your chance of heart failure by consuming lemon juice regularly, due to its vitamin B content.
Simply drink a cup of warm water with the juice from half a lemon added to it each morning on an empty stomach. For best results, do not add salt or sugar.

Garlic
Several studies have demonstrated blood pressure lowering effects of garlic. Both raw and cooked garlic help control high blood pressure and at the same time reduce cholesterol levels. Garlic helps relax blood vessels by stimulating the production of nitric oxide and hydrogen sulphide.

• Eat one or two cloves of slightly crushed garlic daily. You can simply crush them with your hands. Crushing garlic cloves creates hydrogen sulfide, a compound that promotes good blood flow, removes gas and reduces the pressure on the heart. If you do not like eating raw garlic or if it causes a burning sensation, then take it along with a cup of milk.
• You can also mix five or six drops of garlic juice in four teaspoons of water and take it twice a day

Banana
Bananas are one fruit that people with high blood pressure can eat regularly to control it. Bananas are a rich source of potassium, which helps control blood pressure levels. At the same time, they are low in sodium and have no cholesterol, both of which also are good for people with this problem.

So, try to eat one or two bananas daily. Along with bananas, you can try dried apricots, raisins, currants, orange juice, spinach, zucchini, baked sweet potatoes, cantaloupe, and winter squash.

Coconut Water
People with high blood pressure must keep their bodies well hydrated. It is a good idea to drink eight to 10 glasses of water daily. Coconut water is particularly beneficial for lowering blood pressure.

A 2005 study published in the West Indian Medical Journal found that coconut water, being rich in potassium, magnesium and vitamin C can help decrease systolic blood pressure. Along with coconut water, you can also use coconut oil when cooking:

• Grapefruit is another remedy that is useful in preventing high blood pressure. The vitamin content in the fruit helps in toning the blood vessels.

• Make a mixture of 1 teaspoon each of honey and ginger juice with 1 teaspoon of cumin powder, stir well and consume this mixture twice a day for treating high blood pressure.

Onions: It is considered as another medicine for treating high blood pressure. Like garlic, if you have raw onions and drink its juice, you can stabilise your blood pressure levels. Onions have quercetin (an antioxidant flavonol) that increases blood circulation in the body, increases production of blood and also reduces the chances of heart stroke. Have raw onion salad and drink its juice to flush out toxins from the body and control hypertension.

Make a juice of 25-30 curry leaves with 1 cup of water. Strain and drink first thing in the morning. Limejuice can be added for taste.
