Pett,55 Director of the Division of Nutrition, Department of National Health and Welfare of Canada, has on the basis of the "best data possible,.. . admittedly not entirely satisfactory," arrived at the following figures for the thiamine requirements of 15 individuals ... 

The capsules contained a mean of 82 mg feverfew and thus the level of activity calculated as parthenolide can be estimated as 0.67%. Other studies quote 0.87% sesquiterpene lactones calculated as parthenolide [27] and 0.25-0.30% of active (antimicrobial) material [33]. Bohlmann s extraction of individual components from the dried plant yielded 116 mg sesquiterpene lactones/kg dried feverfew which amounts to less than 0.01 % [17]. Another extraction yielded 330 mg endoperoxides/kg and 56 mg canin/kg alone [19] which would amount to a level of sesquiterpene lactones of at least 0.04%. Thus, the level of sesquiterpene lactones appears to vary with different sources of the plant and this could have been due to a number of factors including the conditions in which feverfew was grown, the season in which it was picked and the way in which it was stored. Another important determinant of the parthenolide content of feverfew appears to be the geographical location. A recent survey of commercial preparations found that all the North American commercial products tested contained less that 0.1% parthenolide, wheras much higher values were obtained for British products. A minimum level of 0.2% parthenolide in commercial products has been proposed by the Health Protection Branch of Health and Welfare Canada [71].

Health and Welfare Canada calculated a value of 0.02 mg/kg/day or 700 /zg/L by using 90 mg/kg/day as the minimum effect dose from the National Cancer Institute bioassay in the rat and applying a 5000-fold safety factor (40).

In Canada, the Health Protection Branch (HPB), Health and Welfare, fulfills the responsibilities by establishing MRLs for pesticides in foods and by establishing programs to ensure compliance with these MRLs (30).
