  • Dhatrak S et al. Effect of herbal combination in low bone mass density patients. Int J Drug Discov Technol. 2011. 2(1): 9-14. - In this double blind, randomized, placebo control trial in women (45-60 years old¬) with low BMD identified by DEXA scan (n=30), supplementation of an herbal combination containing Calzbone® showed significant improvement in bone density parameters namely BMD, T score, and Z score, while also showing a reduction in serum total ALP activity (most commonly used biochemical markers to assess bone turnover (formation and resorption)) in the active treatment group compared to placebo. During the six-month period of this study, BMD was found to increase by 2.74 % in the Calzbone® group.

  • Goswami SS et al. Efficacy of Cissus quadrangularis (Calzbone®) in perimenopausal low bone density women. Antiseptic. 2011. 108(10): 504-6. - This study was done to evaluate efficacy and safety of Calzbone® in perimenopausal low bone mass density (BMD) women, identified by DEXA scan (45-55 years old, n=40), at the dose of one capsule three times a day for six months. A significant improvement in bone density parameters, BMD, T score, and Z score with a 17% improvement in bone density was reported at the conclusion of the study indicating decreased future fracture risk. Serum total ALP activity was found to decrease significantly at the end of the study compared to baseline. Calzbone® was well tolerated.

  • Thawani V et al. Effect of herbal combination containing Cissus quadrangularis (Calzbone®) in  fracture healing. Antiseptic. 2002. 99(9): 345-7. - In this open pilot study, an herbal combination containing 250mg of Calzbone® was administered at in one capsule three times a day was to ten patients with fractures of long bones of the leg and whose fracture had been fixed with an interlocking nail. The average fracture healing time for these patients, which is known to normally be 16-20 weeks, was reduced to 12-14 weeks. Calzbone® was well tolerated.
