The forms of dosage included decoctions, pills, capsules, tablets, granules, tinctures, liniments, and powders. These preparations are traditionally used in the treatment of skin and subcutaneous tissue diseases. A total of 400 medicinal materials were used in preparations, including 339 from plants, 40 from animals, 14 from minerals.
