Ban Liu Wan is a 3-ingredient Chinese Medicine formula with Sulfur (Liu Huang) as a principal ingredient.

Invented in 1107, it belongs to the category of formulas that warm and purge. Its main actions are: 1) fortifies the Fire at the Gate of Vitality and 2) expels Cold.

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 Ban Liu Wan is used by TCM practitioners to fight patterns like Yang Deficiency or Empty Yang or Empty-Cold. From a Western Medicine standpoint, such patterns can give rise to a range of conditions such as constipation in the elderly, chronic diarrhea or impotence for instance.

On this page, after a detailed description of each of the three ingredients in Ban Liu Wan, we review the patterns and conditions that Ban Liu Wan helps treat.

Conditions and patterns for which Ban Liu Wan 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 Ban Liu Wan 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:

Constipation in the elderly Chronic diarrhea Impotence Constipation

Again it wouldn't be correct to say "Ban Liu Wan treats constipation in the elderly" for instance. Rather, Ban Liu Wan is used to treat patterns that are sometimes the root cause behind constipation in the elderly.

Now let's look at the two patterns commonly treated with Ban Liu Wan.

Yang Deficiency or Empty Yang

Ban Liu Wan is sometimes prescribed by TCM practitioners to treat Yang Deficiency or Empty Yang. This pattern leads to symptoms such as feeling of cold, desire warmth, pale urine and undigested food in the stools. Patients with Yang Deficiency or Empty Yang typically exhibit deep (Chen), empty (Xu), slow (Chi) or weak (Ruo) pulses as well as Pale, swollen and moist tongue with possible white or wet coating.

Yang Deficiency is an Empty-Cold condition characterized by Coldness and Deficiency. If there is inadequate amount of Yang energy to warm the body or internal Organs, a general hypoactivity of the organic processes occurs, hence the patient is tried and not willing to move.  Qi and Blood is more... read more about Yang Deficiency or Empty Yang

Empty-Cold

Ban Liu Wan is sometimes prescribed by TCM practitioners to treat Empty-Cold. This pattern leads to symptoms such as feeling of cold, cold limbs, pale face and no thirst. Patients with Empty-Cold typically exhibit deep (Chen), slow (Chi) or weak (Ruo) pulses.

Full-Cold is mainly caused by external Cold Evil invasion or Yin Excess, while Empty-Cold is largely due to Deficient Yang or Qi, which fails to warm the body. Therefore the patients have cold limbs,  feel cold and dislike cold. 

Both pattern has Cold manifestations, but the Empty type is more for... read more about Empty-Cold
