A:  Cissus is used for this purpose and is a supplement. In clinical trials, Cissus led to fracture healing times 33% to 55% higher than other calcium promoting bone matrix preparations. The way it works is that is is a kind of antiglucocorticoid - controlling cortisone that can be catabolic and degrading to bone and bone matrix, as well as skeletal muscle tissue. Numerous studies link cortisol with bone degredation, as well as other ill effects, including fat accumulation.  By exerting an anabolic/ antiglucocorticoid effect, Cissus helps preserve muscle tissue during times of physical and emotional stress. The possibility exists that Cissus may improve bone healing and improve the healing rate of connective tissue in general, including tendons. This would make it highly valuable as a supplement to bodybuilders, powerlifters and fitness competitors. One of the other great things about it is that it appears to also exhibit some fairly strong analgesic properties on a mg per mg basis, comparable to aspirin or anti-inflammatory drugs like Ibuprofen. Reduction of swelling and promoting the process of healing via preventing the conversion of arachidonic acid to inflammatory prostaglandins. This is a significant discovery and is a truly beneficial supplement for all bodybuilders and their recovery from workouts and injuries, as well as for injury prevention.
