Query: RESPONSE DUKE NUKEM'S WARNING

MR. NUKEM IS CORRECT THAT BORAGE OIL CAN CONTAIN PYRROLIZIDINE ALKOLOID (P.A.) WHICH IS TOXIC FOR THE LIVER, BUT P.A. IS CONTAINED IN THE LEAVES OF THE PLANT ONLY AND IN SMALL AMOUNTS (10PPM). HOWEVER, THE SEED DOES NOT CONTAIN HARMFUL ALKALOIDS. BORAGE SEED OIL IS THE HIGHEST KNOWN PLANT BASED SOURSE OF GAMMA-LINOLENIC ACID AND IS EASILY TOLERATED BY MOST PEOPLE. HOWEVER, BEFORE TAKING ANY SUPPLEMENT, REFER TO YOUR DOCTOR BECAUSE PERSONS ON BLOOD THINNERS AND OTHER HEALTH CONDITIONS PROBABLY SHOULD NOT BE TAKING THIS SUPPLEMENT. ALSO, DO YOUR OWN RESEARCH. THERE IS SO MUCH INFORMATION OUT THERE ABOUT THIS SUPPLEMENT. BY THE WAY, I ONLY RATED THE ITEM 2 STARS BECAUSE AMAZON DOES NOT LET YOU LEAVE FEEDBACK WITHOUT SOME TYPE OF RATING. I CAN'T HONESTLY RATE THIS ITEM BECAUSE I'VE ONLY BEEN TAKING IT FOR THE PAST WEEK. I WILL EDIT MY REVIEW IN A MONTH OR SO AND GIVE A HONEST STAR RATING. BE WELL . . .
