This study was planned by the necessities of basic information about the effects of Korean Ginseng upon fracture healing and biomechanical properties of bone. Three hundred white mice were used for this study, and we could have tested the biomechanical properties in one hundred and nintyfour. The bones of the white mice were evaluated by testing gross stability, radiological appearance, and biomechanical properties. It appears that Korean Ginseng has an excellent effect upon early phase of fracture healing of the bone. The summary of this study are as follows: 1. With near maximal dose, Korean Ginseng showed very excellent effect upon early phase of the fracture healing. 2. There was no apparent effect on remodeling phase of the fracture healing with Korean Ginseng of near maximal dose. 3. Korean Ginseng appeared to have no effect on fracture healing with minimal dose. 4. Upon biomechanical properties of the bone, Korean Ginseng was seemed to be effective with near maximal dose. But, there was no definite evidence for that.
