Yes, I learned about this folk prescription 10 years ago. I told my colleagues and friends that the effect was really good. If you want to persist for a long time, you don't need to take antihypertensive drugs. It's better to boil with water before drinking, and the effect will be better. At the same time, it will be better to rub Yongquan point after soaking feet with hot water every night. Please try it and you will be satisfied. Wish you good health.
