| Research Abstract |
A histamine release test involving stimulating cultured P815 cells with A23187 demonstrated the significant inhibitory effects of a crude oil on histamine release. An Nc/Nga mouse model of atopic dermatitis demonstrated the inhibitory effects of crude and purified oils on skin scores, ear swelling, and serum histamine levels. In a human intervention trial, the purified oil was effective in 3 of 7 patients with atopic dermatitis and all 16 patients with senile xerosis, without any adverse event. Thus, yuzu seed oil alleviated atopic dermatitis-like symptoms.
