Cancer - "In experiments using mice, hypericin was shown to accumulate specifically in tumor tissue. When these hypericin-treated mice were irradiated, tumor growth was inhibited. Similar results have been found in human tumor cell lines. Hypericin was taken up by the tumor cells, rendering them more vulnerable to the killing effects of specific types of light. These results suggest that hypericin can be used as a phototherapy tool when treating cancer." Hypercin might be useful as a transport agent to get cancer-killing nutrients into cancer cells. It is already being tested for use with orthodox Photodynamic Therapy (PDT).
