A new study has shown that it is possible to build tolerance from peanut allergies.
Parents have praised a landmark study that found that participants are usually unable to withstand exposure to up to one-tenth of the allergen could ultimately survive two peanuts.
Children with severe allergies participated in a year-long study, where they were increasingly given peanut protein.
From the fact that pollen has already been used, it was hoped that immunotherapy therapy could protect people from life-threatening reactions, says Mirror.
A six-year-old girl who participated in the trial said she had "completely changed her life".
Sophie Pratt said: "Before Emily took part, we were uncomfortable about being more than twenty minutes away from the hospital and she could not attend a play or party without me or when my husband was there.
"We had to continually examine food labeling to ensure that peanuts were completely removed from the Emily diet.
His allergy was very serious, so a small amount of peanut can lead to a very serious reaction. The impact on family life was enormous. "
The 44-year-old said that by the end of the year Emily was able to withstand seven peanuts.
In the PALISADE survey, nearly 500 four to 17-year-olds were recruited from the United States and Europe to participate in the largest peanut allergy treatment.
Participants were divided into groups that received either capsule peanut protein or puppy powder.
The doses were gradually increased every two weeks for six months before continuing the "maintenance dose" of the peanut for another six months.
According to studies published in the New England Journal of Medicine, about 67% of children and teenagers were able to withstand at least 600 mg of peanut protein compared to only 4% of placebo.
Professor George du Toit, Evelina London Pediatric Allergy Consultant and Research Senior Researcher, said: "Peanut allergy is very difficult to manage for children and their families because they have to adhere to a rigorous ground-nutrition diet.
"Families live in fear of accidental exposure because allergic reactions can be very serious and even result in death.
"Until recently, there is nothing to offer the peanut allergy suffer from other than training about peanut avoidance and recognition and self-treatment of allergic reactions."
Earth's allergy, possibly life-threatening, has doubled over the last two decades and affects about one in 50 children in the UK.
Allergy has rarely grown and is the most common cause of food allergy sufferers.
The PALISADE study was funded by Aimmune Therapeutics, which produces the peanut protein used in the experiment and is conducted by researchers at Evelina London Children's Hospital and King's College London.
