All right. But, as I think, in pharmaceuticals, not only herbs are considered (and not only herbs from Botany). There, attention is apparently paid to parts of plants. For example, the drawing of a fruit on f102v2, which resembles a turnip. In general, this is possible, because we use only the ginger root, not the entire ginger plant. If another part of the plant is not interesting, there is probably no point in showing it.
This also suggests that the barrels in the Pharmacy represent the type of medicine, such as infusions, decoctions, potions, balms, etc.
