X-Ray fluorescence spectrometry using Ti, Ni, Se, and Cs as internal standards was developed for the multi-elemental analysis of the Chinese crude drug "Ryukotsu". The analytical results for various "Ryukotsu" samples indicated that their Ca contents are 30-37%, and that no significant difference in the Ca content was observed between the compact tissue and spongin tissue. K and Fe concentrations in the spongin are higher than those in the compact tissue, while the compact tissue contains P and I at higher levels than the spongin tissue. In addition, brown and black parts outside the compact tissue contained Fe and Mn at high levels, respectively. It is also characteristic of the metal profile of "Ryukotsu" that most samples contain U and Y. The studies on the elution of inorganic constituents from "Ryukotsu" suggest that the fine particles of "Ryukotsu" may be absorbed by the human body. It was also suggested that the role of "Ryukotsu" in various prescriptions is not only the release of inorganic constituents but also the effect of removing some harmful substances in the decoction.
