WARNING! Apricot seeds can cause CYANIDE POISONING!! My husband and I have eaten apricot seeds from time to time as a preventative measure against any cancer that may be unknowingly in our bodies. Yesterday I had the idea that maybe we could grind them into a powder and take them that way. In the evening he tried it: ground some seeds (approx 40) in the coffee grinder and took approx 1 1/2 TBSP, chasing with water. In a few minutes he started feeling dizzy. I got on the internet and read about apricots and cyanide poisoning (oh no!) He immediately took Vitamin C to try and expel the poison. We drove to the hospital and parked in the ER parking lot (just in case, as some of the possible symptoms are comatose and death). Over about an hour he took a total of 3000mg Vit C and 500mg Resveretrol. He also drank copious amounts of water! His skin was redder than usual and he was cold (his hands especially were very cold to the touch). He experienced some nausea. Lessons learned: 1) ALWAYS research BEFORE experimenting 2) B17 in Apricot seeds is powerful stuff... be sure to consult someone with experience in using it!
