My friend at mahjong say drinking boiled 螺旋草 tea, the uncaria vine, every day cure high blood pressure better than my tablets. Neighbour Auntie Ling also do this, she throw away her losartan and amlodipine already, say no need anymore. Now my head feel a bit dizzy sometimes but the tea smell bitter only. Can I stop the blood pressure medicine forever and just drink the tea?
