Wu Zhu Yu Tang is a 4-ingredient Chinese Medicine formula with Evodia Fruits (Wu Zhu Yu) as a principal ingredient.

Invented in 220 AD, it belongs to the category of formulas that warm the middle and dispel Cold. Its main actions are: 1) warms and tonifies the Liver and Stomach and 2) directs Rebellious Qi downward.

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 Wu Zhu Yu Tang is used by TCM practitioners to fight patterns like Stomach Yang Deficient and Cold or Cold invading the Stomach. From a Western Medicine standpoint, such patterns can give rise to a range of conditions such as acute gastroenteritis, cholecystitis or morning sickness for instance.

On this page, after a detailed description of each of the four ingredients in Wu Zhu Yu Tang, we review the patterns and conditions that Wu Zhu Yu Tang helps treat.

Conditions and patterns for which Wu Zhu Yu 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 Wu Zhu Yu Tang is used by TCM practitioners to treat two 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:

Acute gastroenteritis Cholecystitis Morning sickness Pyloric spasm Neurogenic headache Migraine headache Hypertension Trigeminal neuralgia Meniere's disease Eye fatigue Corneal ulcers Conjunctivitis Acute congestive glaucoma Recalcitrant hordeolum Acute gastritis Peptic ulcers Chronic hepatitis Bacillary dysentery Ulcerative colitis Chronic gastritis Recalitrant perimenopausal vomiting Chronic cholecystitis

Again it wouldn't be correct to say "Wu Zhu Yu Tang treats acute gastroenteritis" for instance. Rather, Wu Zhu Yu Tang is used to treat patterns that are sometimes the root cause behind acute gastroenteritis.

Now let's look at the two patterns commonly treated with Wu Zhu Yu Tang.

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

Stomach Yang Deficient and Cold

Wu Zhu Yu Tang is sometimes prescribed by TCM practitioners to treat Stomach Yang Deficient and Cold. This pattern leads to symptoms such as epigastric pain relieved with pressure or eating, poor appetite, preference for warm drinks and foods and vomiting of clear fluids. Patients with Stomach Yang Deficient and Cold typically exhibit deep (Chen), slow (Chi) or weak (Ruo) pulses.

Also called Stomach Yang Deficiency, this pattern is normally associated with Spleen-Yang Deficiency, which leads to Internal Cold, resulting in cold limbs, loose stools, vomiting of clear fluids, no thirst, preference for warm drinks and foods and a Weak pulse.

Cold invading the Stomach

Wu Zhu Yu Tang is sometimes prescribed by TCM practitioners to treat Cold invading the Stomach. This pattern leads to symptoms such as severe epigastric pain, feeling of cold, cold limbs and preference for warm drinks and foods. Patients with Cold invading the Stomach typically exhibit deep (Chen), slow (Chi) or tight (Jin) pulses.

Pathogenic Cold blocks the Stomach and prevents Stomach-Qi from descending, hence the vomiting and the pain.

Cold impairs the Yang of the Stomach and Spleen and prevents the food essences from reaching the body, hence the feeling of cold, the Slow pulse, the preference for warm liquids and... read more about Cold invading the Stomach
