Honokiol is a compound extracted from the Chinese Magnolia Tree (Magnolia Officinalis). It has been used as an herbal remedy for anxiety in China and Japan at low daily doses in tea for 2000 years. Honokiol has been found to kill cancer cells through the process of anti-angiogenesis --- restricting the microscopic blood vessels that feed cancer cells. As such, if effective in humans, then Honokiol may have a use against most forms of cancer. If Honokiol proves to remain at a significant level in the human bloodstream before being broken down and eliminated by the body, then as an oral or i.v. agent Honokiol might also make an effective addition to a cocktail of anti-angiogenesis "Targeted Drugs"
