Photodynamic therapy is a type of therapy using a photosensitizer, an organic compound, combined with light to induce cellular death through a process called photothermal energy. PDT has been found to have the potential to kill harmful microbial organisms, including viruses, fungi and bacteria.
Photodynamic Therapy can be administered via exposure to light or as a therapy where the light is delivered through the use of light-sensitive devices. The light emitted from the light source may be either ultraviolet light (UV) or blue light (OL). Depending on the light source, PDT has different light spectrum characteristics.
The photodynamic light therapy has the potential to destroy a wide range of infectious agents, by inducing cellular destruction and death of all microorganisms in the pathogen’s environment. As a result, the PDT treatment is known to kill many types of microbes.
Photodynamic Therapy, also known as Photothermal Therapy
This the method of light treatment used to treat some infections, as well as Photodynamic Therapy for cancer treatments. Photodynamic Therapy is also very effective in combating fungal and viral infections. A recent study showed that a photodynamic-based disinfection method may have an effective role in the treatment of the common cold and flu.
Furthermore, there is evidence that it can prevent the spread of infection from one person to another and that it has the potential to kill viruses and fungi, thereby reducing the risk of transmission of viral and fungal diseases to humans.
Another benefit of Photodynamic Therapy is its ability to inhibit the growth of bacteria in the mouth and gut, helping to reduce symptoms of allergies and asthma. PDT has been shown to be an effective adjunct to other natural therapies for these conditions.
What is the Healing Properties of Photodynamic Therapy
The healing properties of Photodynamic Therapy are apparent in many areas of the human body where microorganisms and fungi live. These include
- Gastrointestinal tract
- Skin, respiratory tract
- Urinary bladder
- Urethra and bladder
Photodynamic Therapy may have benefits in treating chronic illnesses, including arthritis and eczema, but it is not yet clear whether it would have an effect on the treatment of cancer. Other than that, it is also being researched to be a complementary therapy for treating other systemic diseases, such as diabetes and HIV. and chronic kidney failure. Its mechanism of action is not well understood.
Photodynamic Therapy has been reported to be a safe, effective and cost-effective alternative to traditional medical therapies. The treatment for chronic diarrhoea is based on a theory which holds that photodynamic treatment reduces intestinal inflammation and increases absorption of nutrients from the intestine.
This theory is not supported by scientific data, however, and there is no evidence that photodynamic phototherapy is beneficial in preventing dehydration or promoting healing. In some cases of photodynamic treatment, no visible effects occur until months or even years later. Read: Could photothermal therapy become the ‘gold standard’ of cancer treatment?
Some patients may report increased symptoms or tenderness at the site of photodynamic treatment, which may be due to an allergic reaction to some of the dye used in photodynamic treatments
The treatment of eczema, however, is well known to have an immediate, noticeable positive impact on the skin’s appearance, as well as to improve skin texture and reduce the amount of itch and irritation felt in the affected area. It has been used successfully in this way for many years.
While there is a lack of scientific research into the effectiveness of Photodynamic Therapy as a treatment for cancer, it appears to be useful in helping patients to fight cancer. Some patients have seen a dramatic improvement in their cancer survival rates after photodynamic treatment, including in the treatment of
- Breast cancer
- Hodgkin’s disease
- Multiple myeloma and
While Photodynamic Treatment does not cure cancer, it is an attractive alternative because it does not require surgery or drugs to help patients heal themselves. In addition, it does not cause side effects, and it requires little or no maintenance.
