Upper Chamber Teapills – Cang Er Zi Wan
Traditional Chinese Herbal Formula for the Nose & Nasal Passages | Plum Flower | 200 Teapills
Does your nose feel stuffy, blocked or difficult to clear?
Upper Chamber Teapills, traditionally known as Cang Er Zi Wan, is a classic Chinese herbal formula traditionally used when Wind and other TCM patterns interfere with the normal openness of the nasal passages.
The formula combines Cang Er Zi (Xanthium fruit), Bai Zhi (Angelica dahurica root), Xin Yi Hua (Magnolia flower) and Bo He (Mint).
What makes this formula particularly easy to understand is its traditional focus: the nose and upper nasal passages.
Upper Chamber comes as small prepared teapills, so there are no loose herbs to measure and no decoction to prepare.
What Is Upper Chamber – Cang Er Zi Wan?
Cang Er Zi Wan is a prepared version of the traditional Chinese herbal formula associated with Cang Er Zi San.
In Traditional Chinese Medicine, the formula is traditionally used to:
-
Dispel Wind
-
Open the nasal passages
-
Benefit the nose
-
Dispel turbidity
These are Traditional Chinese Medicine functions, not Western medical diagnoses or treatment claims.
What Does "Dispel Wind and Open the Nose" Mean?
Traditional Chinese Medicine uses terms such as Wind and turbidity to describe patterns rather than specific diseases.
In everyday language, someone researching Cang Er Zi Wan may be looking for a traditional formula when the nose feels stuffy, obstructed or difficult to clear.
That does not mean every case of nasal discomfort represents the same TCM pattern. Persistent, severe or unexplained symptoms should be appropriately evaluated.

What's in Upper Chamber Teapills?
Upper Chamber uses a focused combination of four traditional herbs associated with the nose and upper portion of the body.
| Pin Yin | Botanical Ingredient | Traditional Role |
|---|---|---|
| Cang Er Zi | Xanthium sibiricum fruit | Traditionally dispels Wind and benefits the nose |
| Bai Zhi | Angelica dahurica root | Traditionally dispels Wind and opens the nasal passages |
| Xin Yi Hua | Magnolia biondii flower | Traditionally opens the nasal passages and benefits the nose |
| Bo He | Mentha haplocalyx herb | Traditionally disperses Wind and clears the head |
Why Is Cang Er Zi the Featured Herb?
Cang Er Zi (Xanthium fruit) gives the traditional formula its name.
In Chinese herbalism, Cang Er Zi has a particularly strong traditional association with the nose and nasal passages.
It is combined with Bai Zhi and Xin Yi Hua, two additional herbs traditionally associated with the nose, while Bo He complements the formula through its traditional Wind-dispersing properties.
Is Upper Chamber the Formula You're Looking For?
Upper Chamber is worth investigating when you're specifically searching for a traditional Chinese herbal formula associated with nasal openness and the nose.
Someone researching Cang Er Zi Wan might recognize descriptions such as:
"My nose feels stuffy or obstructed."
"I'm looking for a traditional formula specifically associated with the nasal passages."
"I've been told to look for Cang Er Zi Wan or Cang Er Zi San."
"I want Cang Er Zi, Bai Zhi and Xin Yi Hua together in a prepared formula."
The important distinction is that Cang Er Zi Wan is a specific traditional formula, rather than a general-purpose supplement for every type of nasal or respiratory complaint.
Why These Four Herbs?
Cang Er Zi — Xanthium Fruit
Cang Er Zi is traditionally associated with dispelling Wind and benefiting the nose. It is the defining herb of Cang Er Zi Wan.
Bai Zhi — Angelica Dahurica Root
Bai Zhi has a long history in Chinese herbalism and is traditionally associated with dispersing Wind and opening the nasal passages.
Xin Yi Hua — Magnolia Flower
Xin Yi Hua is another traditional Chinese herb strongly associated with the nose and nasal passages.
Its inclusion alongside Cang Er Zi and Bai Zhi gives Upper Chamber its concentrated traditional focus on the nose.
Bo He — Mint
Bo He is traditionally associated with dispersing Wind and clearing the head. It complements the three principal nasal-focused herbs in this prepared formula.
Why Teapills & How Do I Use Them?
Traditional Chinese herbal formulas can be prepared by measuring individual herbs and simmering them in water to make a decoction.
Upper Chamber Teapills provide the formula in a much more convenient prepared form.
There is no measuring, simmering or straining. Simply take the teapills with water according to the product directions.
Label Directions
Take 8 teapills, 3 times per day.
At the label directions of 24 teapills per day, one 200-count bottle provides approximately 8 days of use.
Follow the product label unless your qualified healthcare professional or Traditional Chinese Medicine practitioner has provided different instructions.
Cang Er Zi Wan vs. Cang Er Zi San — What's the Difference?
These names can be confusing when you're shopping for Chinese herbs.
Cang Er Zi San is the name commonly associated with the traditional herbal formula.
Cang Er Zi Wan refers to a prepared pill form associated with that traditional formula.
The word Wan generally indicates a pill, while San traditionally refers to a powder.
This Plum Flower product is sold as Upper Chamber Teapills – Cang Er Zi Wan and contains 200 prepared teapills.
Modern Research on the Upper Chamber Herbs
The herbs in Cang Er Zi Wan have long histories of traditional use. Modern researchers have also investigated their botanical constituents and biological activities.
Traditional Chinese Medicine use and modern scientific evidence are not the same thing. Laboratory, animal and preliminary clinical research should not be interpreted as proof that Upper Chamber Teapills prevent, treat or cure a disease.
