Although the author

Although the authors of the original paper replied that the binding
of the oil to the beta-cyclodextrin was intentional, thus providing a
slow release of activity, they failed to address the more difficult problem
of whether therapeutic levels of allyl sulfides were ever attained
(Berthold, Sudhop, and von Bergmann, 1998). In their minds, this
was considered unnecessary because “convincing evidence of lipidlowering
effects of any garlic preparation is still lacking.” No reference
in support of this assertion is provided. The 17 positive of 20 total
studies cited by Lawson are dismissed as lacking rigorous design,
but the defects are not specified. They do concede that “conclusions
of our study apply only to the preparation we used. . . .” Unfortunately,
that was not the way it was reported in the popular press,
which labeled all garlic preparations ineffective for blood lipid reduction.
