Peanut allergy is increasingly common, especially in countries such as UK and Australia. There is currently no accepted routine clinical therapy to cure peanut allergy. Recently studies have looked at desensitising people with peanut allergy by giving them small daily doses of roasted peanut. Although this therapy works for some people, its effects are not generally long lasting and it is associated with many side effects during protocol, resulting in a significant rate of drop-outs.
