The Immune Defense Herbal Tea, or Yu ping feng tang in Chinese, owes its name to the image of a "jade screen" that envelops and protects the body.

Composed of three major tonics from the Chinese pharmacopoeia: Atractylode root (Bai zhu), Silerian root (Fang feng) and Astragalus root (Huang qi), this herbal tea tonifies the Qi (Vital life force) and increases the immunity of the body. It thus allows you to overcome fatigue, slack and changes of season and to regain physical and mental fitness.
