Suan Zao Ren Tang is a 5-ingredient Chinese Medicine formula with Jujube Seeds (Suan Zao Ren) as a principal ingredient.

Invented in 220 AD, it belongs to the category of formulas that nourish the Heart and calm the Mind. Its main actions are: 1) nourishes the Blood and 2) calms the Mind and eliminates irritability .

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 Suan Zao Ren Tang is used by TCM practitioners to fight patterns like Liver Blood Deficiency, Heart Blood Deficiency or Empty-Heat or Fire caused by Yin Deficiency. From a Western Medicine standpoint, such patterns can give rise to a range of conditions such as insomnia, sleep walking or nervous exhaustion for instance.

On this page, after a detailed description of each of the five ingredients in Suan Zao Ren Tang, we review the patterns and conditions that Suan Zao Ren Tang helps treat.

Lastly, it coordinates the effects of other herbs and brings harmony to the Middle Burner.

Conditions and patterns for which Suan Zao Ren Tang may be prescribed

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 Suan Zao Ren Tang is used by TCM practitioners to treat five 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:

Insomnia Sleep walking Nervous exhaustion Paroxysmal tachycardia Hypertension General anxiety disorder Depression Schizophrenia Hepatolenticular degeneration Trigeminal neuralgia Migraine Angina pectoris Chronic hepatitis

Again it wouldn't be correct to say "Suan Zao Ren Tang treats insomnia" for instance. Rather, Suan Zao Ren Tang is used to treat patterns that are sometimes the root cause behind insomnia.

Now let's look at the five patterns commonly treated with Suan Zao Ren Tang.

The Liver is a so-called "Zang" Organ. Learn more about the Liver in Chinese Medicine

Liver Blood Deficiency

Suan Zao Ren Tang is sometimes prescribed by TCM practitioners to treat Liver Blood Deficiency. This pattern leads to symptoms such as blurred vision, dull-pale complexion, scanty periods and numbness in the limbs. Patients with Liver Blood Deficiency typically exhibit choppy (Se) or fine (Xi) pulses as well as Pale tongue, especially on the sides with thin, dry and white coating.

This pattern has all the general manifestation of the Blood Deficiency, such as dizziness, pale lips, dull pale face. The Liver stores Blood, that is the reason any Blood Deficiency often involves the Liver.

Heart Blood Deficiency

Suan Zao Ren Tang is sometimes prescribed by TCM practitioners to treat Heart Blood Deficiency. This pattern leads to symptoms such as easily scared, excessive dreams, palpitations and insomnia. Patients with Heart Blood Deficiency typically exhibit choppy (Se) or fine (Xi) pulses as well as Pale thin and slightly dry tongue .

Empty-Heat or Fire caused by Yin Deficiency

Suan Zao Ren Tang is sometimes prescribed by TCM practitioners to treat Empty-Heat or Fire caused by Yin Deficiency. This pattern leads to symptoms such as feeling of heat in the afternoon, dry mouth, desire to drink in small sips and dry throat at night. Patients with Empty-Heat or Fire caused by Yin Deficiency typically exhibit rapid (Shu), empty (Xu) or floating (Fu) pulses as well as Red tongue with no coating .

Yin Deficiency involves the excessive consumption of Body Fluids, Essence and Blood. The main cause is overwork, which usually develops very gradually and slowly over several years. The only exception to a rapid Yin Deficiency is when Pathological Heat consumes Body Fluids and Yin very fast.
