Those are good examples. The frog is certainly not common in herbal manuscripts. It's quite common in alchemical manuscripts and I'm assuming it has a symbolic significance.
Venomous frogs are generally found in South America and southeast Asia. I don't think there are any in northern Europe or the Mediterranean area (I'm not certain about this, but I can't think of any off the top of my head) so it seems unlikely that the plant is used to treat frog toxins. There are some medicinal and magical recipes that include frog parts.
In manuscripts where the order of the animals is not alphabetical, I don't know whether the frog might be a reference to a wetland plant. Another possibility is that it might refer to a plant name (e.g., frog-bit, frog cup, frog crowfoot, etc.).
Both Himalayan balsam and Amomum have roots like 32v but the flowers and leaves don't match.
The roots and leaves of 32v resemble Potentilla, but not the flowers.
The root and flowers resemble Campanula rapunculus, but not the leaves.
As far as I know, neither of these latter two plants is associated with frogs by name or by habitat (they tend to grow in meadows and fields rather than wetlands).
