Still, there are other alternatives, such as acupuncture or EECP (Enhanced External Counter Pulsation). Ask your doctor what options are best for your health. Generally, acupuncture is safe despite not yet being confirmed for its effectiveness in lowering blood pressure.
Then, take your blood pressure regularly to see if your medicine works. You can either do it by yourself at home in the morning, or make an appointment and have it checked by your doctor. In case of any changes in lifestyle, such as taking herbal medicine or suffering from stress, just tell your doctor.
