I think what he/she means is that cod liver oil has anti inflamatory properties (it has, acording to some research I have seen) and
that this might help with inflamed acne. And also that (Weston) Price was right that cod liver oil is healthy.
Personally I take cod liver oil on and of and I dont see much difference in acne activity. Not enough to rule out that it fluctuating
is due to other causes, at least.
