Receiving anticoagulants (Subjects receiving anticoagulants may be enrolled after discontinuation of anticoagulant therapy and return of INR level to within normal limits (INR < 1.2) before dosing day. Subjects receiving platelet inhibitors (including garlic) must be off the inhibitors for at least 6 days or more. Subjects unable to discontinue anticoagulant therapy may not be enrolled in this study);
