Chlorine E6 is a derivative of chlorophyll, the natural dye that plants produce during photosynthesis. The photosensitizer chlorin E6, which is extracted for medicinal purposes from the green alga Chlorella ellipsoidea, is used in photodynamic therapy (PDT) for the treatment of tumors. The special feature of chlorin E6 is its interaction with light of a specific wavelength. When cancer cells are exposed to a laser, chlorin E6 is activated and interacts with oxygen. This results in the energy-rich, short-lived singlet oxygen that specifically destroys cancer cells.
PDT with chlorin E6 is an extremely gentle procedure that has few, if any, side effects. Health risks are also significantly lower in contrast to the classical cancer therapies currently being propagated. This is because PDT only targets the tumour, whereas it has no effect on healthy cells.
In most cases, it is sufficient to perform PDT with chlorin E6 once, as it has a drastic effect. However, PDT can also be repeated more often if necessary.
Note: PDT is also an excellent method of treatment for those patients in whom surgery or other, stressful common cancer treatment methods cannot be performed due to various parameters.
