The three axes are assessed independently and are never combined into a single score.
KTKP records the origin species as Cyperus rotundus L.. It has not yet been cross-checked against the Korean Pharmacopoeia, so the identification confidence is not raised to an official code mapping. The same drug appears under 3 records as name variants. The same source species also yields 1 other separately registered drug(s) (Cyperi Rhizomai Praeparatum), which must not be conflated. The name most used for this taxon in current literature is Cyperus rotundus.
