Peaceful Sleep Formula (An Mian Tang) promotes a restful night's sleep, especially when the sleep is restless, fitful, and disturbed by vivid dreaming. The chief herb in this formula is Suan zao ren (the seed of the jujube date), which is widely known for its ability to "calm Shen"-- that is, bring peace to the Spirit, calm anxiety, and promote restful and even sleep.
