Coffee certainly increases one’s blood pressure, but the effect is often transient. My blood pressure would return to normal about 3 hours after consuming a cup of coffee.
The effect of alcohol, however, seems to be more lasting and presumably more harmful. After a couple of glasses of cider, my blood pressures shoots up. It stayed up there for more than 4 hours.
I decided to try something I’ve learned.
Bilateral taichong 太冲, yuan source point of the Liver Meridian. 15 minutes later, I took my blood pressure again.
Of course, I don’t suffer from hypertension and this is my normal (usual) blood pressure and it may not work for you if you do have hypertension, but it does show that acupuncture can bring down a person’s blood pressure.
