Some teas such as white, green, black, oolong and others contain caffeine. Caffeine has many effects on the body, such as stimulating the central nervous system, so that you feel energetic and alert.
It may also temporarily raise your blood pressure, especially one hour after consumption when it is at its highest concentration in the blood.
The cause of the brief increase in blood pressure is still unclear and some people may be more sensitive to the effects of caffeine than others.
But drinking 1-3 cups of tea containing small doses of caffeine over a long period of time is actually beneficial for lowering blood pressure. This way, the acute effect of caffeine on the body is gradually weakened and it lowers blood pressure with regular consumption.
If you already suffer from high blood pressure, it's best to check with your doctor about whether you should limit or stop drinking caffeinated beverages.
It's also important to avoid consuming large amounts of caffeine before engaging in activities, which naturally raise blood pressure, such as exercise or physical labor.
Licorice tea can also cause blood pressure to rise.
If there are large amounts of sugar in the tea, this can also have a negative effect on the blood.
You must also not forget, that excessive doses of beneficial products such as herbs can have a negative effect on us.
