- Bovine tracheal cartilage (BTC)
For Patients & Caregivers
There is no proof that bovine cartilage can treat cancer or HIV.
Relatively little laboratory experimentation has been done with bovine cartilage. The use of cartilage products against cancer partially stems from the theory that since cartilage does not contain blood vessels, it must contain substances that would prevent the growth of blood vessels around tumors, a process known as angiogenesis. There is some laboratory support for the anti-angiogenic properties of shark cartilage, but almost none for bovine cartilage. Catrix®, a bovine cartilage product, was used in a laboratory experiment against isolated samples of several cancer cell lines, with positive results at high doses. However, there is still little evidence that these anti-cancer effects can take place in the human body.
Because bovine cartilage supplements may contain the same specialized proteins that make up human cartilage, they might assist with the resynthesis of cartilage in people with osteoarthritis. This theory has not been borne out in humans in clinical trials, however. It has been suggested that bovine cartilage can enhance immune response as well, but this effect has not been shown in humans.
- To reduce swelling associated with arthritis
No scientific evidence supports this use.
- To prevent and treat cancer
Although a few laboratory studies supported this use, clinical studies are lacking.
- To treat HIV and AIDS
There is no scientific evidence to support this use.
- To stimulate the immune system
There are no clinical data to validate this claim.
For Healthcare Professionals
Derived from the cartilage, usually the trachea, of cows. This product should not be confused with shark cartilage Bovine cartilage is used to prevent and treat cancer and treat HIV/AIDS; it may be administered via oral and parenteral routes. Several in vitro studies suggest bovine cartilage may have antitumor and immunoregulatory effects (2)(3)(6). Few published clinical trials demonstrate its efficacy (4)(5).
Nausea and vomiting are commonly reported adverse events. Other effects reported include changes in taste perception, fatigue, dizziness, and dyspepsia. Inflammation and irritation at injection sites are common following parenteral administration. No drug interactions are known.
Immunoregulatory effects are believed to enhance antibody responses to T-independent and T-dependent antigens, indicating that its activity is due in part to a direct effect on B cells or an indirect effect mediated by macrophages. It is believed to support the resynthesis of cartilage in osteoarthritis.
