Photodynamic Therapy (PDT)
Photodynamic therapy, which is used in the ImunoMedica clinic, is an effective cancer treatment method. Contrary to chemotherapy, this therapy does not affect the immune function; instead, an immunising effect is seen as a result of the use of this technique. As a result, photodynamic therapy can also be used in immunocompromised patients.
At the Immunomedica clinic, a photosensitizing drug is administered intravenously or directly into the tumor. The photosensitizer binds to pathologically altered tissue with extremely high specificity. After a predetermined time interval, light is delivered intravenously or externally via a laser of the appropriate wavelength. This is absorbed by the targeted cells, resulting in the production of reactive oxygen species that destroy tumor cells via apoptosis, necrosis, or alteration of the tumor vasculature.

Hypericin, derived from St. John's wort, is the most potent natural photosensitizer, absorbing yellow light (590 nm).UV 375 nm
Ultraviolet light deactivates pathogens and stimulates the immune system.
