Glauber’s salt, also known as sodium sulfate decahydrate, might not be the first thing that comes to mind when you think of Traditional Chinese Medicine (TCM). But don’t let its humble appearance fool you – this mineral compound packs quite a punch in the world of natural remedies.
Let’s dive into why this seemingly simple substance has earned its place in the TCM pharmacopeia.
What is Glauber’s salt?
Before we get into the nitty-gritty, let’s break it down. Glauber’s salt is essentially sodium sulfate with ten water molecules attached (Na2SO4·10H2O)1. It’s named after the 17th-century German-Dutch chemist and apothecary Johann Rudolf Glauber2. In TCM, it’s known as “mangxiao” or “xuanmingfen.”
The power of simplicity
You might be wondering, “How can something so basic be used as medicine?” Well, as the old saying goes, “Don’t judge a book by its cover.” In the world of pharmaceuticals, it’s not about looks – it’s all about effectiveness. And Glauber’s salt certainly delivers in that department.
Main functions in TCM
According to TCM theory, Glauber’s salt has two primary functions3:
- Purgative and laxative effects: It helps relieve constipation and softens hard stools.
- Clearing heat and reducing swelling: It’s used to treat inflammation and swelling in various conditions.

How does it work?
The magic of Glauber’s salt lies in its ability to retain water in the intestines. When dissolved, it forms a hypertonic solution that draws water into the bowel, increasing the volume of intestinal contents4. This leads to:
- Softening of stools
- Stimulation of bowel movements
- Usually results in a bowel movement within 4-6 hours of ingestion
Interestingly, its mechanism of action is similar to that of lactulose, another well-known laxative5.

Clinical applications
Internal use
Glauber’s salt is primarily used for treating constipation6, especially when it’s accompanied by symptoms like:
- Abdominal distension and pain
- Fever
- Intestinal abscesses
In TCM terms, these symptoms are often associated with a condition called “Yang Ming Fu Shi,” characterized by heat accumulation and constipation.
External use
Don’t think Glauber’s salt is just for internal issues! It’s also applied externally for78:
- Mastitis (inflammation of the breast tissue)
- Hemorrhoids
- Other inflammatory conditions
A word of caution
As with any medical treatment, it’s not one-size-fits-all. Glauber’s salt isn’t suitable for everyone. Here are some important precautions9:
- Not recommended for those without excess heat in the body
- Elderly or weak individuals should use it cautiously
- It’s generally not used for chronic constipation
The bottom line
While it might seem surprising that a simple salt can be such a versatile TCM material, Glauber’s salt proves that sometimes, less is more. Its ability to address multiple issues through a straightforward mechanism makes it a valuable tool in the TCM practitioner’s arsenal.
Remember, though, that while natural remedies can be effective, it’s always best to consult with a qualified healthcare professional before starting any new treatment regimen. After all, your health is nothing to take with a grain of salt – Glauber’s or otherwise!
