Tu Si Zi Wan is a 11-ingredient Chinese Medicine formula with Cuscuta Seeds (Tu Si Zi), Pilose Antlers (Lu Rong), Desert-Living Cistanches (Rou Cong Rong) and Yam (Shan Yao) as principal ingredients.

Invented in 1253 AD, it belongs to the category of formulas that warm Yang and tonify. Its main actions are: 1) warms the Kidneys and 2) prevents abnormal leakage such as urinary incontinence or seminal emissions.

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 Tu Si Zi Wan is used by TCM practitioners to fight patterns like Kidney Essence Deficiency, Kidney Qi not Firm or Kidney Yang Deficiency. From a Western Medicine standpoint, such patterns can give rise to a range of conditions such as urinary incontinence, seminal emission or premature ejaculation for instance.

On this page, after a detailed description of each of the eleven ingredients in Tu Si Zi Wan, we review the patterns and conditions that Tu Si Zi Wan helps treat.

Conditions and patterns for which Tu Si Zi 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 Tu Si Zi Wan is used by TCM practitioners to treat three 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:

Urinary incontinence Seminal emission Premature ejaculation

Again it wouldn't be correct to say "Tu Si Zi Wan treats urinary incontinence" for instance. Rather, Tu Si Zi Wan is used to treat patterns that are sometimes the root cause behind urinary incontinence.

Now let's look at the three patterns commonly treated with Tu Si Zi Wan.

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

Kidney Essence Deficiency

Tu Si Zi Wan is sometimes prescribed by TCM practitioners to treat Kidney Essence Deficiency. This pattern leads to symptoms such as deafness, mental dullness, retardation and softening of bones. Patients with Kidney Essence Deficiency typically exhibit empty (Xu) or floating (Fu) pulses as well as Red and peeled tongue .

Kidney Essence (Jing 精) Deficiency usually involves Deficiency of Kidney Yin and, to some extent, Kidney Yang. Its signs manifest in relation to growth, development, reproduction, sexuality, bones, marrow, the brain, teeth, memory and hair.

Kidney Qi not Firm

Tu Si Zi Wan is sometimes prescribed by TCM practitioners to treat Kidney Qi not Firm. This pattern leads to symptoms such as sore lower back, weak lower back, abundant urination and weak stream urination. Patients with Kidney Qi not Firm typically exhibit deep (Chen) or weak (Ruo) pulses as well as Slightly Pale tongue.

This pattern is also called ‘Lower Original Qi (元气 Yuan Qi) not Firm’, to show that it is also caused by a shortage of the Original Qi. When Original Qi is weak in the Lower Burner, Qi cannot hold Body Fluids which leads to many 'leaking' symptoms of the sperm, vaginal discharge or urination.
