Or probably she's allergy to one of its ingridients?
Its the snack (the green chips) not the beauty product
Makes sense since he saw the pollen in the product, so it has to be good. Either she ate green pea chips for the first time or that particular brand is no good.
That's what happen in the novel, so yeah sorry this is a *spoiler* (▰˘◡˘▰)
Oh, yeah. Forgot she ate onr before
that means the natural beauty products are no good
