Purpose: The purpose of this study is to evaluate the synergic efficacy of oriental herb medicine for osteoporosis patients by examining whether there is any change in BMD. Osteoporosis patients are classified into a group having taken Fosamax and the other group having taken Fasamax and Samgieumgamibang in this study. Methods: Mean BMD and T-score are measured in all patients before and 3 months after treatment. Results: 1. The group having taken Fosamax showed no statistically significant mean BMD change before and after treatment. 2. The group having taken Fosamax showed no statistically significant T-score change before and after treatment. 3. The group having taken both Fosamax and Samgieumgamibang showed increase in mean BMD, which does not bear statistically significant change. 4. The group having taken both Fosamax and Samgieumgamibang showed statistically significant T-score change before and after treatment(p<0.05). Conclusions: After treatment, BMD in patients having taken Fosamx did not change significantly, but in patients having taken both Fosamax and Samgieumgamibang increased, which proves the efficacy of oriental herb medicine for osteoporosis patients.
