Sorry to be late chiming in on this one. First I have high blood pressure and cholesterol. I started backpacking again partially due to this senario. I have been on blood pressure medicine since age 36 or 37.I started because I was having chest pain.I i have had numerous stress and stress eco test! However,since started walking and hiking again a year and a half ago, My bp meds have been cut in half as have my cholesterol. I am 47 now! The crystal aspirin dose intriged me so I mentioned it to my wife. My wife is in the medical field and she said just put a asprin or two under your tounge to disolve. This is apparently the most direct route to the blood stream via topical. I will not mention the other! Anyway, I though this ifo may help someone who could need it
