Wu Shao She is the dried body of a snake, used as a single herb in Chinese medicine. It is also called Black-Striped Snake. It is used for long-term joint pain, stiff limbs, muscle spasms and itchy skin.
It is an animal drug, not a plant. The snake is cleaned, coiled, dried, then sliced or ground to a powder. It is often soaked in strong wine or cooked with other herbs.
Here is the short evidence line. Wu Shao She has a long record in Chinese medicine, but good human trials are missing. A long history of use is not proof that something works, and we say that once here rather than in every section below.
No one has shown how Wu Shao She works in the body. The lab and animal studies are few and small.
In Chinese medicine it is said to move through the channels and drive out wind-damp (an old term for pain that shifts around and gets worse in cold, wet weather). It is also said to calm spasms and stop itching.
Some lab work suggests that snake tissue holds proteins and fats that may calm swelling. That work was not done in people. So treat any talk of a mechanism (how it works) as a guess for now.
You will most often meet it as dried slices or as a fine powder.
Dried slices are boiled with other herbs to make a strong tea, called a decoction. Powder is stirred into warm water or packed into capsules.
Medicinal wine is also common. The dried snake is soaked in strong grain spirit for weeks, and the liquid is then taken in small amounts. This form carries alcohol.
It also turns up in ready-made pills, plasters and patches sold for joint pain. In most of those, it is one herb among many. Buy only from a seller who tests for germs and heavy metals.
Wu Shao She has been used in China for more than a thousand years. It appears in the Kaibao Bencao, a drug text from the 10th century.
Doctors have long used it for stiff, sore joints, for spasms and for stubborn skin rashes. It sits near Bai Hua She, another snake drug, but is seen as gentler.
It is a staple of one tradition, Chinese medicine. It has no matching record in other systems.
Some reactions to Wu Shao She need urgent care. Call your local emergency number or go to an emergency department straight away — do not wait to see whether it passes.
Call emergency services at once if your lips, tongue or face swell, if you struggle to breathe, or if a rash spreads fast over your body. These are signs of a severe allergic reaction.
See a doctor soon if you get a fever, chills, vomiting or diarrhoea that will not stop after taking it. This may point to a germ in the product.
Book a doctor's visit if your joint pain is no better after four weeks, if a joint turns hot, red and swollen, or if new numbness, weakness or a facial droop appears. A sudden facial droop or weakness on one side is an emergency.

The published evidence for Wu Shao She is weak or absent. That usually means no controlled trial has tested it, not that a trial found it ineffective — the two are different, and we grade only what has been published.
What it is typically used for, usual dose, cautions, and the study behind it where real trial data exists.
