This is just my subjective view, but I think the authors got the cost of the geneware "Allergen Treatment" wrong. $25,000 and .1 essence loss is a HUGE price to pay to reduce an allergy severity by 1 step.
There is already a karma cost to eliminate a negative quality, and it is far cheaper to do that than to pay for these treatments, when looking at it from the standard exchange rate of $2000 per karma.
Cost to buy off allergy with karma: 4 (Plutonium makes me itchy) to 40 (eating gluten will kill me)
Converting that to nuyen: 8,000 to 80,000
Allergen Treatment geneware: 25,000 to 100,000, plus permanent essence loss of .1 to .4
IMO the cost should've been balanced around the karma buyoff number, for better compatibility with popular houserules like Working for the Man/People
