An article in the 2005 International Journal of Oncology states that "…oil extract of Gac fruit was found to be effective in the treatment of liver cancer. In cancer research, it has been suggested that the bioactive components of Gac fruit are its antioxidants, which may have effects on cancers related to oxygen free radicals, such as liver, colon and breast cancer. However, other components may also have anticancer properties."

"…this investigation clearly indicated that Gac fruit contains a protein of 35 kDa possessing direct antitumor and antiangiogenic effects against certain cancers. Gac fruit should be considered as a functional food and medicinal resource for the prevention and treatment of various diseases including cancer, diabetes retinopathy, and chronic inflammation. It is hoped that the results of this study will be used as scientific basic data for the further study and ultilization of Gac fruit in pharmaceutical and nutritional intervention."

Results from a number of population studies show that people with high lycopene intake or high lycopene levels in the body are at a lower risk for developing certain types of cancers. Lycopene has been found to inhibit breast cancertumors more efficiently.Lycopene intake was inversely associated with risk for ovarian & cervical cancers.  Intake of dietary lycopene may also play a role in the prevention of prostate cancer.  "An 83% reduction of prostate cancer risk was observed in the group with the highest plasma concentration of lycopene in comparison with individuals with the lowest concentration. The strength of the association was directly related to dose; with increasing concentrations of plasma lycopene, the risk of prostate cancer was decreased."  

From this fruit Gac oil capsule  has been made.
