Enzyme Potentiated Desensitisation (EPD)

Dr Damien Downing on Enzyme Potentiated Desensitisation

EPD is now administered by a very small injection intradermally (into the top layer of the skin, usually on the forearm) every few weeks. It was developed at St Mary's Hospital in the 1960s, and ever since by Dr Leonard McEwen, who has made it his life's work. EPD treats reactions to a number of different allergens without the need for a tailor-made formula for each one.

There have been 10 trials using EPD for inhalant allergies; 9 of them showed a significant positive effect. Many people find that about 6 treatments over 3 years produce a lasting protection against seasonal allergies such as hay fever - although many also choose to continue having a yearly booster to ensure protection.

The small number of studies done in other diagnoses have shown positive results for Ulcerative Colitis, ADHD and childhood migraine. Clinical experience (ours and that of many others) over 30 years is that it can provide valuable protection in many diseases and symptoms caused/triggered by food intolerances and chemical sensitivities. Chronic fatigue, bowel disorders, asthma and eczema, migraine, depression and even epilepsy, arthritis and fibromyalgia, and symptoms due to Candida sensitivity have all been treated succesfully.
