Typically for clinical herbalism I would expect something like:
Intake/assessment, including patient history
Differential diagnosis
Research, development of treatment protocol, dosage, etc.
Medicine-making
Treatment
Follow-up, checking compliance, etc
Adjust/repeat based on follow-up results
Unfortunately, most of those are hard to take pictures of, and also potentially very difficult for staff to assess for safety, accuracy, etc.
Maybe wood or iron badge could be something like treating 3 patients for one year, including at least one chronic condition with lab work to check key indicators over time (blood lipids, or c-reactive protein, or blood sugar, or whatever). That would cost some money and require outside verification, though. It's hard to think of how to show improvement in most medical conditions through photographs alone. Maybe some skin conditions.
Another option (maybe for wood) might be something like:
For the following [12] herbs, provide pictures/video of you preparing them in the following ways:
Infusion or maceration
Decoction
Syrup
Tincture or glycerite
Vinegar
Oil
Salve
Honey [maybe not, since not vegan friendly]
Compress or poultice
Powder
Or, if you do have not prepared the herb in one of these ways, explain why (for instance, a highly aromatic or mucilaginous herb isn't ideal for a decoction, the desirable components aren't
water soluble, etc).
Include a copy of your journal pages detailing your recipes and dosage information, the uses of the herbal preparation (including the differences between different preparations of the same herb), your treatment protocol, and how you/your patient responded to treatment.
Include a picture of sketches you have made showing the habit of the plant and its leaves, flowers, fruits, seeds,
roots, or any other parts useful for medicine or identification (not judged on artistic merit).
Also include photographs and a list of components of an herbal first-aid kit equipped for treating acute injury or illness.
