Yeas ago I advised Oolong tea for various skin conditions, known in naturopathic literature,but I seem to have disappeared for the Israeli market.

Oolong tea helps in the treatment of stubborn atopic dermatitisAn open Japanese study suggests that consumption of oolong tea (Camellia sinensis) helps speed clearance of recalcitrant atopic dermatitis lesions. The 118 study participants continued their usual dermatologic treatments but also drank oolong tea (10 g steeped in 1000 mL water a day, divided into three doses). Beneficial results were noted after one to two weeks, and 74 (63%) of the participants showed marked to moderate improvement of lesions after one month. After 6 months, 64 patients (54%) still demonstrated a good response to treatment. The study builds on animal research showing that oral administration of green, black, or oolong tea suppressed allergic skin reactions. Uehara M, Sugiura J, Sakurai K.
