Which tea is good for high blood pressure?
High blood pressure or hypertension is a common condition that affects millions of people around the world. It is a major risk factor for heart disease and stroke, two leading causes of death. Managing high blood pressure often involves lifestyle changes, including diet. Tea, one of the most consumed beverages in the world, has been studied for its potential health benefits, including blood pressure control. But the question remains: can tea actually help lower blood pressure?
Does tea lower blood pressure?

Ashwagandha
Ashwagandha, often called Indian ginseng, is an adaptogen that has been used in Ayurvedic medicine for centuries. It is known for its stress-reducing effects, which is important because stress can be a contributing factor to high blood pressure.
Although Ashwagandha is not traditionally consumed as a tea due to its strong taste, it can be taken in powder form and added to warm water or milk.Limited studiessuggests that ashwagandha may help lower blood pressure by reducing stress and improving cortisol levels – if blood pressure is caused by stress.
Hibiscus
Hibiscus tea, made from the vibrant flowers of the hibiscus plant, is not only delicious but may also have health benefits for people with high blood pressure. Studies have shown that hibiscus tea can do thathelp lower blood pressurein people with mild to moderate hypertension. The anthocyanins and other antioxidants in hibiscus are thought to contribute to its blood pressure-lowering effects.
Green tea
Green tea is perhaps one of the most researched types of tea when it comes to health benefits. It is rich in catechins, a type of antioxidant that may help protect against heart disease by lowering blood pressure and improving cholesterol levels.
Some studies have shown that regular consumption of green tea can lead to:modest reduction in blood pressure. However, green tea also contains caffeine, which may negate these benefits in some individuals.
Cardamom
Cardamom is a spice commonly used in South Asian cooking and traditional medicine. Although not a tea in the traditional sense, cardamom can be steeped in hot water to make a flavorful drink.
Some research suggests that cardamomcan help maintain healthy blood pressurelevels in people with hypertension. Its antioxidant properties and potential effects on improving blood circulation may be the reasons for its blood pressure-lowering potential.
Tea that can increase blood pressure
While certain teas may be beneficial for controlling high blood pressure, it is important to note that any food or drink containing caffeine can temporarily increase your blood pressure. Caffeine can cause a brief but significant increase in blood pressure by constricting blood vessels and increasing the effects of stress. When you're stressed, your heart rate increases, and caffeine can increase this effect.
Therefore, if your goal is to lower blood pressure, it may be best to avoid or limit consumption of caffeinated teas, such as black tea, oolong tea, and some green teas. Instead, opt for caffeine-free versions or naturally caffeine-free herbal teas such as hibiscus or hawthorn.
In conclusion, certain types of tea, especially those rich in antioxidants and without caffeine, can contribute to lower blood pressure. Hibiscus, green tea (in moderation), sea buckthorn, ashwagandha and cardamom are some options that may provide benefits. However, it is crucial to remember that drinking tea alone is unlikely to significantly lower blood pressure without other healthy lifestyle choices. A balanced diet, regular exercise, maintaining a healthy weight and avoiding excessive alcohol consumption are also important components in controlling high blood pressure. Always consult a healthcare professional before making any major changes to your diet, especially if you have health conditions or are taking blood pressure medications.
