There are many uncommon (or weird) syndromes listed in the clauses of MSGC (Medical Synopsis of the Golden Chamber). Sometimes it is the key to cure the disease properly if noting these uncommon syndromes. Paraconsistent propositional logic limits the applicable scope of law of contradiction using various ways. It prevents contradiction from hurting the whole theoretical system after limiting the contradiction. We can investigate the contradiction and special relationship between clauses using paraconsistent propositional logic perspective. We hope traditional Chinese Medical doctors can give special notice to uncommon syndromes in clinical treatment through the investigation of paraconsistent propositional logic.
