Additional Information

Gambogic acid is the principal pigment of gambooge resin which, in addition to early medicinal uses in Southeast Asia, is also a sought after dye due to the bright orange color it imparts to cloth. According to traditional Chinese medical documentation, gamboge was described as poisonous and acidic and possessed the ability to detoxify, kill parasites, and stop bleeding as a hemostatic agent. Gambogic acid has also been used in various food preparations in Asian cultures. (   In studies conducted with mice and transplanted tumors (from human lung carcinoma SPC-A1 cells), tumor growth remained suppressed for up to 21 days during treatment with gambogic acid. The ratio of relative tumor volume (RTV) for the treated group of mice to the control group indicates the gambogic acid was having an impact on tumor size while having no adverse effects on body weight or mortality. Tumor volume was measured twice each week during the study, and the ratio of treated to control group tumor volume ranged from 45.0% to 72.7% for the 8 mg/kg dose and from 55.6% to 78.8% for the 4 mg/kg dose. Tumor growth rate shows a dependence on the dose of gambogic acid, with the 8 mg/kg dose providing improved results at suppressing tumor growth in these trials. (   The effect of gambogic acid on the growth of SPC-A1 cells was also investigated. Cells were cultured with various concentrations of gambogic acid, and then living cells were counted. The results indicate that both the concentration of gambogic acid used to treat the cells as well as the length of treatment affected the growth inhibiting factor. For the same length of exposure, the higher the concentration of gambogic acid that was administered, the greater the effect on inhibiting cell growth. When comparing cultures at the same dose, the longer the cells were exposed to gambogic acid, the higher the growth inhibition. Results indicate that cell growth is dependent on both the magnitude of the dose administered as well as the length of time exposed to gambogic acid. (
