Shark cartilage has been used in traditional Chinese medicine for thousands of years for its immune-building effect. It is an abundant source of mucopolysaccharides
that are reported to stimulate the immune system promoting optimal health. Shark cartilage is also said to contain vital amino acids, protein, calcium, and phosphorous. It is used for its pain relief and anti-inflammatory properties to aid in the treatment of arthritis and other joint injuries. It has been used in humans to treat cancer and psoriasis also.
In humans, it is recommended to avoid the use of shark cartilage after a heart attack, during pregnancy, or if open lesions exist. Until appropriate research studies on animals have been performed, the same contraindications should apply to pets.
