Topics in Complementary and Alternative Therapies (PDQ®)

Pharmacologic Treatments


714-X is a chemical compound that contains camphor, a natural substance that comes from the wood and bark of the camphor tree. Nitrogen, water, and salts are added to camphor to make 714-X. It is claimed that 714-X protects the immune system and helps the body fight cancer. No peer-reviewed studies of 714-X has been published to show that it is safe or effective in treating cancer.

  • See the PDQ patient summary on 714-X for more information.


Antineoplastons are drugs made of chemical compounds that are naturally present in the urine and blood. It has been claimed that antineoplaston therapy can be used to stop certain cancer cells from dividing, while healthy cells are not affected.


Cancell/Cantron/Protocel is a liquid that has been made in different forms since the late 1930s. It is also known by the names Sheridan’s Formula, Jim’s Juice, JS-114, JS-101, 126-F, and the "Cancell-like" products Cantron and Protocel. The exact ingredients of Cancell/Cantron/Protocel are not known and it is not effective in treating any type of cancer.

Cartilage (Bovine and Shark)

Bovine (cow) cartilage and shark cartilage have been studied as treatments for people with cancer and other medical conditions for more than 30 years. Substances that prevent the body from making the new blood vessels that a tumor needs to grow have been found in bovine cartilage and shark cartilage. However, these substances have not shown an effect on the growth of normal cells or tumor cells.

Hydrazine Sulfate

Hydrazine sulfate is a chemical that has been studied as a treatment for cancer and as a treatment for body wasting (i.e., cachexia) that can develop with this disease. It has been claimed that hydrazine sulfate limits the ability of tumors to take in glucose, which is a type of sugar that tumor cells need to grow.


Laetrile is another name for the chemical amygdalin, which is found in the pits of many fruits and in numerous plants. Cyanide is thought to be the active anticancer ingredient of laetrile. Laetrile has shown little anticancer activity in animal studies and no anticancer activity in human clinical trials.

Newcastle Disease Virus (NDV)

Newcastle Disease Virus (NDV) is usually thought to be an avian (bird) virus, but it also infects humans. It causes a potentially fatal, noncancerous disease (Newcastle disease) in birds, but causes only minor illness in humans. NDV appears to copy itself much better in human cancer cells than in most normal human cells and may have anticancer effects.
