I ingested San Pedro last week, it was an increditble experience but I am not posting to speak of it. My experience was on Sunday (4 days ago). Today Thursday I have fallen ill w/ flu like symptoms. I work in the medical field and i see lots of people. I was wondering if the cactus could have altered or lowered my immune system or was this illness just lurking in me waiting to make me miserable. Any insight on this would help. I personally feel that the plant would help combat whatever is trying to hurt but am not sure. Thanks in advance for your time!
