Initial benefits of oolong tea were first noticed after 1-2 weeks of treatment. Marked to moderate improvement was observed in 74 (63%) of the 118 patients after 1 month. After 6 months of treatment, a good response was still observed in 64 patients (54%). The authors attribute oolong tea’s beneficial effects in the recalcitrant AD cases to the antiallergic properties of the tea’s polyphenols.
