RT Journal Article SR Electronic T1 Sale of kava extract in some health food stores JF Canadian Medical Association Journal JO CMAJ FD Canadian Medical Association SP 1158 OP 1159 VO 169 IS 11 A1 Edward Mills A1 Rana Singh A1 Cory Ross A1 Edzard Ernst A1 Joel G. Ray YR 2003 UL http://www.cmaj.ca/content/169/11/1158.abstract AB IN JANUARY 2002, HEALTH CANADA ISSUED AN ADVISORY, followed by a ban in August 2002, on the sale of herbal kava. One month after the advisory, 22 (67%) of 33 health food stores approached were selling kava. Two months after the ban, 17 (57%) of 30 stores continued to sell kava. These findings demonstrate that health food stores may need to be better informed about the sale of restricted natural health products.
