Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
Participants were recruited through local advertising and doctor referrals from hospital outpatients and general practice clinics.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
The criteria were an age from 19 to 80 years, Histamine skin prick test: above 3mm

Reporting Groups

Chungkookjang(3times/day, 3packs/day, 35g/day) for 12weeks

Chungkookjang: The Chungkookjang was manufactured from raw beans, peels made after freeze-drying


Placebo(3times/day, 3packs/day, 35g/day) for 12weeks

Placebo : Amount and calorie of placebo are same with Chungkookjang.
