Xiao Yao San is a 6-ingredient Chinese Medicine formula with Bupleurum Roots (Chai Hu) as a principal ingredient.
Invented in 1107 AD, it belongs to the category of formulas that harmonize Liver-Spleen. Its main actions are: 1) harmonizes the function of Liver and Spleen and 2) relieves Liver Qi stagnation.
In Chinese Medicine health conditions are thought to arise due to "disharmonies" in the body as a system. These disharmonies are called "patterns" and the very purpose of herbal formulas is to fight them in order to restore the body's harmony.
In this case Xiao Yao San is used by TCM practitioners to fight patterns like Liver Blood Stagnation, Liver Qi Deficiency or Rebellious Liver Qi invading the Spleen. From a Western Medicine standpoint, such patterns can give rise to a range of conditions such as menstrual cramps, low breast milk supply or irregular menstruation for instance.
On this page, after a detailed description of each of the six ingredients in Xiao Yao San, we review the patterns and conditions that Xiao Yao San helps treat.
Chai Hu is a king ingredient in Xiao Yao San. Like the name indicates, it means it has more power than other ingredients in the formula.
Chai Hu To spreads the Liver Qi, relieves Stagnation and helps guide the other herbs into the Liver. Because of its cooling nature, it is also particularly dealing with Qi Stagnation that has started to generate Heat.
Dang Gui is a deputy ingredient in Xiao Yao San. This means it helps the king ingredient(s) treat the main pattern or it serves to treat a coexisting pattern.
Part used: Dried root
Nature: Warm
Meridian affinity: HeartLiverSpleen
Category: Tonic herbs for Blood Deficiency
Dang Gui works together with White peony roots, the other deputy in this formula, to nourish Blood. This nourishing role also in turn helps strengthen the Liver since it stores Blood and is nourished by it.
Bai Shao is a deputy ingredient in Xiao Yao San. This means it helps the king ingredient(s) treat the main pattern or it serves to treat a coexisting pattern.
Part used: Dried root
Nature: Neutral
Meridian affinity: LiverSpleen
Category: Tonic herbs for Blood Deficiency
In general Bai Shao's main actions are as follows: "Tonifies the Blood and preserves the Yin. Nourishes the Liver and assists in the smooth flow of Qi. Regulates the meridians and eases the pain."
In the context of Xiao Yao San, it is used because it moves Qi and is specific for menstrual problems, especially from emotional stress.
Fu Ling is an assistant ingredient in Xiao Yao San. This means that it either serves to reinforces the effect of other ingredients or it moderates their toxicity.
Part used: Dried sclerotium
Nature: Neutral
Taste(s): Sweet
Meridian affinity: HeartKidneyLungSpleen
Category: Herbs that drain Dampness
In general Fu Ling's main actions are as follows: "Encourages urination and drains Dampness. Tonic to the Spleen/Stomach. Assists the Heart and calms the Spirit."
In the context of Xiao Yao San, it is used because it strengthens the Spleen.
Bai Zhu is an assistant ingredient in Xiao Yao San. This means that it either serves to reinforces the effect of other ingredients or it moderates their toxicity.
Part used: Dried rhizome
Nature: Warm
Meridian affinity: SpleenStomach
Category: Tonic herbs for Qi Deficiency
Bai Zhu works together with Poria mushrooms to strengthen the Spleen. Indeed, as described in the famous TCM treaty Essentials from the Golden Cabinet: "When one sees a Liver disorder, one knows that the Liver will transmit it to the Spleen. Therefore, one should first treat the Spleen." Strengthening the Spleen, since it 'rules transformation and transportation', has a direct positive impact on Blood Deficiency.
Gan Cao is an assistant ingredient in Xiao Yao San. This means that it either serves to reinforces the effect of other ingredients or it moderates their toxicity.
Part used: Dried root and rhizome
Nature: Neutral
Taste(s): Sweet
Meridian affinity: HeartLungSpleenStomach
Category: Tonic herbs for Qi Deficiency
Gan Cao tonifies the Spleen and, when combined with White peony roots (as is the case here), helps reduce the spasms that are often a symptoms for patients that use this formula.
It's important to remember that herbal formulas are meant to treat patterns, not "diseases" as understood in Western Medicine. According to Chinese Medicine patterns, which are disruptions to the body as a system, are the underlying root cause for diseases and conditions.
As such Xiao Yao San is used by TCM practitioners to treat eight different patterns which we describe below.
But before we delve into these patterns here is an overview of the Western conditions they're commonly associated with:
Menstrual cramps Low breast milk supply Irregular menstruation Abnormal vaginal discharge Late menstruation Hepatitis Cholecystitis Peptic ulcers Gastric neurosis Chronic gastritis Cirrhosis Premenstrual syndrome Fibrocystic breasts Perimenopausal syndrome Pelvic inflammatory disease Uterine fibroids
Again it wouldn't be correct to say "Xiao Yao San treats menstrual cramps" for instance. Rather, Xiao Yao San is used to treat patterns that are sometimes the root cause behind menstrual cramps.
