 - Background
Cancer remains a major public health threat even though there have been breakthroughs in conventional diagnostics and therapies. Alternatively, treatment with mild hyperthermia and herbal medicine treatment [selected using traditional Korean medicine theory 4 qi (cold, cool, warm and hot) and using the 5 senses of taste (sour, bitter, sweet, pungent and salty)], may be an option to promote cancer cell death in patients where the cancer is accessible.
Methods
To investigate effect of combination treatment of herbal medicines and hyperthermia in vitro on cancer cell lines (ACHN, AGS, A549 and U937), the qualities of 38 medicinal herbs and sensitivity to mild hyperthermia (42 and 43°C) treatment were examined. An assay was performed to detect cell viability and proliferation (MTT) following exposure to medicinal herbs and hyperthermia.
Results
Heat sensitizing herbal medicines were determined to be larger in the warm and hot groups of medicinal herbs (29.6%) than the groups which were neither warm nor hot (18.2%). In addition, the proportion of heat sensitizing effect with bitter and pungent flavors was 33.3 % and 32.1 %, respectively, greater than the average (26.3 %).
Conclusion
In conditions of mild hyperthermia in cancer cell lines, incubation with herbal medicines caused cancer cell death in vitro. These results suggest that the use of traditional herbal medicines with warm, hot, pungent and bitter characteristics may be a useful treatment for cancer using conditions to induce mild hyperthermia and this requires further investigation.
