  • Changes in Histamine-induced Wheal Size [ Time Frame: 12weeks ] [ Designated as safety issue: Yes ]
    Histamine-induced wheal size was measured in study visit 1(0 week) and visit 3(12 week).
  • Number of Participants With Greater Than 40% Decrease in Histamine-induced Wheal Size (Wheal Size by More Than 40% Decrease in the Number of Subjects Compared With Placebo) [ Time Frame: 12weeks ] [ Designated as safety issue: Yes ]

    Number of Participants with Greater than 40% Decrease in Histamine-induced Wheal Size was measured in study visit 1(0 week) and visit 3(12 week).

    Percentage change in histamine-induced wheal size calculations were calculated by the formula ((12weeks - 0weeks) * 100/0weeks).

    Number of Participants with Greater than 40% Decrease in Histamine-induced Wheal Size compared with placebo.

A Human Trial to Evaluate the Effects of Chungkookjang on Histamine-induced Wheal Size in Healthy Subjects
Efficacy and Safety of Chungkookjang, a Fermented Soy Paste, on Histamine-induced Wheal Size

The investigators investigate the effect of Chungkookjang on histamine-induced skin reaction in a double-blind, randomized, placebo-controlled, human trial

Sixty volunteers (aged 20-80) who gave a written consent before entering the study, were randomized in two groups of thirty subjects each. The skin prick test with histamine was performed on the ventral forearm, 10 cm from the elbow, before and after supplement administration, as well as three times daily for 12 weeks of chungkookjang(35g/day) or placebo(35g/day)intake.
