Re-training your immune system not to overreact to the environment started in the early 70s in the UK and is know as EPD and is still practiced. It was refined for North America usage due to the FDA laws and is known here as LDA (http://www.drshrader.com/lda_therapy.htm). It's a different method than above to teach your immune cells the difference between friend and foe, but with the same goal/results in mind.
