Xiao Yao Wan, also known as "Free and Easy Wanderer," is a Traditional Chinese Medicine (TCM) herbal formula with a rich history dating back to the Song Dynasty (960-1279 AD). This formulation is prized for its ability to promote emotional balance and overall well-being. This article explores the benefits, uses, and potential side effects of Xiao Yao Wan, providing a comprehensive overview of this popular herbal remedy.
Historical Context
Xiao Yao San (XYS), the foundation of Xiao Yao Wan, is a traditional Chinese medicine (TCM) formula documented in Tai Ping Hui Min He Ji Ju Fang, a collection of prescriptions written during the Song Dynasty around 1078-1085 AD. It has been used for centuries in China to treat mental disorders such as depression.
Composition and Mechanism
Xiao Yao Wan consists of eight key herbs:
- Bupleuri radix (Chai Hu)
- Angelicae radix (Dang Gui or Dong Quai)
- Paeoniae radix alba (Bai Shao)
- Atractylodis rhizome macrocephalae (Bai Zhu)
- Poria cocos (Fu Ling)
- Zingiberis siccatum rhizome (Sheng Jiang)
- Menthae haplocalycis (Bo He)
- Glycyrrhizae radix (Gan Cao or Licorice)
In TCM, Xiao Yao Wan works by regulating Liver qi, strengthening the Spleen, and tonifying blood. The liver is considered the most important organ in a woman, regulating her menstrual cycle and fertility. The mechanism of action may involve soothing the liver, invigorating the spleen, nourishing the blood to restore normal menstruation, and clearing away liver fire due to blood deficiency. Biochemically, XYS may reverse CIS-induced decreases in brain-derived neurotrophic factor (BDNF) and increases in tyroxine hydroxylase (TrkB) and neurotrophin 3 (NT-3) in the frontal cortex and hippocampal CA subregion.
Common Uses and Benefits
Xiao Yao Wan is widely recognized for its mood-regulating effects and is often prescribed for the following conditions:

Emotional Well-being
Xiao Yao Wan is primarily used to soothe congested qi from the liver, helping to alleviate stress, anxiety, and depression. It moves and disperses liver qi throughout the body, promoting a sense of relaxation and emotional balance.
- Depression: Accumulating evidence suggests its potential in treating depression. A systematic review of 26 RCTs involving 1,837 depressive patients found that XYS and its modified forms combined with antidepressants (SSRIs, tricyclics, and tetracyclics) were superior to antidepressants alone. The formulae also improved HAMD scores without increasing the number of adverse events.
- Anxiety: Both XYS and Jia Wei XYS have been studied for their potential anxiolytic effects. Systematic reviews and meta-analyses have reported that XYS, alone or in combination with conventional medicine, helped improve sleep quality and relieve anxiety.
Digestive Health
Xiao Yao Wan can protect the spleen and stomach, shielding the digestive system from future problems. It may reduce symptoms and recurrence rates in people with gastrointestinal (GI) disorders such as irritable bowel syndrome, constipation, and indigestion (dyspepsia).
Women's Health
Xiao Yao Wan is traditionally used to regulate liver function in women, which helps regulate the menstrual cycle and fertility. It can also help ease mood changes during pre-menstrual syndrome (PMS).
