On follow-up visits, 58 of 61 patients (95.1%)
in the ginger group and 60 of 62 patients (96.8%) in the
vitamin B6 group had 100% compliance. Four patients
(6.3%) in the ginger group correctly identified what
they were taking, but none in the vitamin B6 group. One
patient (1.6%) in the ginger and four patients (6.3%) in
the vitamin B6 group took other medications during
this trial because four patients had a common cold and
one had headache. Three of 61 patients (4.9%) in the
ginger group and 4 of 62 patients (6.5%) in vitamin B6
group took other ginger products.
