This study was purpose to investigate that Gucheokbogol-tang(GBT), mainly used in osteoporosis, has possible regulatory effect on bone regeneration by operating in proliferation and calcification of osteoblast. So that, their cytotoxicity and proliferation was investigated with MTT by ELISA, and morphological change was observed by optical microscope and electron microscope. And activation of alkaline phosphates(ALP) which is secreted in early stage of bone formation was measured, and accumulation of $Ca^{2+}$ in the process of calcification was investigated by alizaline red S assay(ARS). The results were as follows: The MG-63 cell, originated from human cell was activated in $10^{-5}$ treated group, and the level of ALP was also increased in the treated group, highest on the third day. And from the outcome of ARS assay of calcification process in the Gucheokbogol-tang(GBT) treated group for 21days. These results suggested that Gucheokbogol-tang(GBT) is effective in proliferation and calcification of osteoblast.
