The contents of mineral elements, like Fe, in LMTCMs were higher than that of nor-LMTCM. The result of analysis of mineral element of 14 LMTCMs by ICP-MS method also showed the content of Fe have something to do with lung meridian tropism effects. The result of the study of platycodon radix approved the laws too. These laws were used to predict if the marine medicines have the lung meridian tropism effects.2. The Compatibility laws of Medicines and their chemical composition in LSP were studied by mining the data of the constituent herbs and their chemical composition. The results showed that the most constituent medicines of lung system prescriptions have lung meridian tropism. Radix glycyrrhizae, herba ephedrae, semen armeniacae amarum, fructus schisandrae Chinese and their compatibility are common in lung system prescriptions. Terpene, alkaloid, steroid, and flavanoid compounds and their compatibility are common in lung system prescriptions.3. The marine phycophyta medicines of LSP were studied by the same method.
