Cissus RX from USPLabs:

Cissus Quadrangularis has been a staple of traditional Indian medicine for centuries. USPlabs researchers discovered the power of this unique herbal remedy and have now made it available to Western athletes and bodybuilders, or anyone else who wants to strenghthen muscle and bone.

Its unique blend of vitamins, minerals, and steroidal compounds not only build and strengthen muscle and bone, but actually promote and speed the healing process of tendon related injuries, while at the same time soothe the pain of sports related injuries. Common painkillers like aspirin only mask the pain of injured muscles, bones, and tendons and can damage the stomach lining and even cause ulcers. Scientific studies have shown Cissus Quadrangularis actually speeds the healing process and prevents ulcers by strengthening the gastric mucosa, the stomach's protective lining.

Cissus quadrangularis is an ancient medicinal plant native to the hotter parts of Ceylon and India. It was prescribed in the ancient Ayurvedic texts as a general tonic and analgesic, with specific bone fracture healing properties. Modern research has shed light on Cissus? ability to speed bone healing by showing it acts as a glucocorticoid antagonist (1,2). Since anabolic/androgenic compounds are well known to act as antagonists to the glucocorticoid receptor as well as promote bone growth and fracture healing, it has been postulated that Cissus possesses anabolic and/or androgenic properties (1,3). In addition to speeding the remodeling process of the healing bone, Cissus also leads to a much faster increase in bone tensile strength. In clinical trials Cissus has led to a fracture healing time on the order of 55 to 33 percent of that of controls. That cissus exerts antiglucocorticoid properties is suggested by a number of studies where bones were weakend by treatment with cortisol, and upon administration of Cissus extract the cortisol induced weakening was halted, and the healing process begun.

With studies showing that hormone replacement therapy in postmenopausal women may increase the risk of breast cancer and heart disease, many women are looking at alternatives to estrogen to help prevent osteoporosis. Although there appears to be no published research showing that Cissus increases bone density in osteoporosis, or helps prevent the disease, the fact that the herb speeds recovery of fractures suggests that may increase bone density as well. It would almost certainly help speed the recovery of fractures that are a common occurrence with osteoporosis. Chronic glucocorticoid therapy is a high risk factor for the development of osteoporosis. Glucocorticoids are believed to interfere with the action of osteoblasts, the cells that are responsible of the deposition of new bone material. The drug mefipristone (RU-486), an antiglucocorticoid as well as progesterone antagonist, has been successfully used to treat osteoporosis but the side effects, such as endometrial hyperplasia, are serious enough to preclude its routine use for the treatment of osteoporosis. Cissus seems to be devoid of such side effects and may prove to be a viable compound in osteoporosis treatment.

While the increased rate of bone healing may be of great significance to persons suffering from chronic diseases like osteoporosis (4), the antiglucocorticoid properties of Cissus are likely of much more interest to the average bodybuilder or athlete, since endogenous glucocorticoids, particularly cortisol, are not only catabolic to bone, but catabolize muscle tissue as well. Numerous studies over the years have suggested that glucocorticoids, including the body?s endogenous hormone cortisol activate pathways that degrade not only bone, but skeletal muscle tissue as well. A recently published report documented exactly how glucocorticoids (including cortisol) induce muscle breakdown: They activate the so-called ubiquitin-proteasome pathway of proteolysis (5). This pathway of tissue breakdown is important for removing damaged and non-functional proteins. However, when it is overactive during periods of elevated cortisol (e.g disease states, stress, and overtraining) excess amounts of normal tissue are broken down as well. By exerting an anabolic, antiglucocorticoid effect cissus helps preserve muscle tissue during times of physical and emotional stress.

Although the bulk of the research on Cissus centers around bone healing, the possibility exists that Cissus may act to improve bone healing suggests it may improve the healing rate of connective tissue in general, including tendons. If this were the case it would be of even greater benefit to bodybuilders and athletes.

Besides the above-mentioned properties of Cissus, the plant is also rich in the vitamins/antioxidants vitamin C and beta-carotene. As analyzed, Cissus quadrangularis contained ascorbic acid 479 mg, and carotene 267 units per 100g of freshly prepared paste in addition to calcium oxalate (6).

The typical recommended daily dosage of Cissus extract is between 100 and 500 mg, depending on the concentration of the extract and the severity of symptoms. For the powder of the dried plant, the Ayurvedic texts recommend a dosage of 3 to 6 grams to accelerate fracture healing. Safety studies in rats showed no toxic effects at dosages as high as 2000 mg/kg of body weight. So not only is Cissus efficacious, it is also quite safe, in either the dried powder form or the commercially available extract.

Cissus also possess analgesic properties on a mg per mg basis comparable to aspirin or anti-inflammatory drugs like ibuprofen. Cissus quadrangularis constitutes one of the ingredients of an Ayurvedic preparation, `Laksha Gogglu', which has been proved to be highly effective in relieving pain, reduction of swelling and promoting the process of healing of the simple fractures as well as in curing the allied disorders associated with fractures (7). The mechanism through which Cissus exerts its analgesic and anti-inflammatory properties has not been well characterized. It may act centrally, but the anti-inflammatory features suggest that it acts by preventing the conversion of arachidonic acid to inflammatory prostaglandins.
