Abstract

Background: At present, insufficient attention and unsatisfactory treatment for short-term insomnia disorder are widespread problems. This group of people should receive safe and effective treatment as soon as possible and avoid developing into chronic insomnia disorder. We hope to intervene and treat these patients through Luohua Anshen oral Liquid, which is made of peanut branches and leaves and has been used to effectively treat insomnia disorder, this method can be conducive to preventing short-term insomnia disorder chronicity and reducing the burden of health economics. Methods: This double-blinded, randomized, placebo-controlled trial will be conducted at Shanghai Municipal Hospital of Traditional Chinese Medicine, Shanghai University of Traditional Chinese Medicine.
