Today, the various "antihypertensive tea" on the market, whether or not it really has the effect of lowering blood pressure.

The answer is yes.

In terms of Chinese medicine, rooibos tea, lotus leaf tea, cornhusk tea, etc., do have some antihypertensive effect.

This is also corroborated by modern medicine.

Like a common antihypertensive drug "compound rooibos tablets", the main ingredient is rooibos extract. Many merchants in the advertisement to the rooibos tea, will also focus on this point.

I also prescribe herbal teas in the outpatient clinic, but for patients with refractory hypertension, herbal teas will be prescribed along with antihypertensive medications to assist in the treatment, mainly for symptomatic improvement. For some patients with pre-hypertension, or low-risk group of first-degree hypertension (i.e., systolic blood pressure of 140-159mmHg, diastolic blood pressure of 90-99mmHg, without complications), when judged to be free of medication, I will recommend patients to improve their lifestyle and drink herbal tea to regulate their body. However, if it is required to take medication to treat hypertension patients, never stop taking medication without authorization, or to reduce blood pressure tea instead of antihypertensive drugs, may lead to serious complications such as stroke.
