I know that a lot of people are not accustomed to enema-medicine, but for some things, it's the best way to get therapeutic compounds, such as Powdered Shark Cartilage, into the system.

Shark cartilage is way over hyped.  It does not address many of the aspects of cancer including the cause, which is most often viruses.  And it does nothing for blood cancers such as lyphomas, leukemias and polycethemia vera.  But some idiot wrote a book called Sharks Don't get Cancer and the public fell for this myth.  The fact is that sharks are less likely to get cancer, but they do get cancer.  And the reason they are more immune than humans has NOTHING to do with their cartilage.  Sharks have much stronger immune systems due to the type of antibodies they form and the fact that they generate antibody and interferon levels 10 times higher than humans do.  They need this added immunity to protect themselves from the water born pathogens they can be exposed to during hunting, fighting ,  from mating bites and even from swimming in contaminated waters.  So the whole sharks don't get cancer concept is nothing more than bogus sales hype.  But it has really contributed to the decline of many shark species, which is another reason the use of shark cartilage should be avoided.  If people want angiogenesis inhibitors they can use any cartilage including bovine (cow) cartilage, which was the first source identified with angiogenesis inhibitors.  All cartilages contain angiogenesis inhibitors.
