Black Fungus Chinese Herb

Black Fungus (Mu Er): A Cleansing Herb for Blood, Lungs, and Circulation

Introduction

Black fungus, known as Mu Er (木耳) in Traditional Chinese Medicine (TCM), is a prized medicinal mushroom often used as both a food and herb to nourish the blood, moisten the lungs, and gently cleanse the body. With its smooth, slightly crunchy texture and neutral flavor, black fungus is commonly included in soups and stir-fries to support circulation, reduce cholesterol, and ease dryness. Its reputation for promoting longevity and blood health has made it a household ingredient across East Asia.

What Is Black Fungus?

Mu Er refers to the dried or fresh fruiting body of Auricularia auricula, a jelly-like mushroom that grows on decaying wood in shaded forests. In TCM, it is considered sweet and neutral in nature, and it enters the Stomach, Liver, and Lung meridians. Traditionally, black fungus is used to nourish and activate the blood, stop bleeding, moisten dryness, and clear heat from the Lungs. It’s also valued for its high fiber content and gentle detoxifying qualities.

Health Benefits of Black Fungus

Nourishes and Activates the Blood
Mu Er is known for improving blood circulation and reducing blood stasis, helping address conditions like irregular menstruation or cold hands and feet.

Moistens the Lungs and Eases Dry Coughs
It helps soothe dry lungs and throat, especially during dry seasons or after prolonged illness.

Clears Heat and Detoxifies the Body
Black fungus is thought to gently remove toxins from the digestive tract and bloodstream, making it ideal for cleansing diets.

Supports Heart Health and Lowers Cholesterol
Its fiber and polysaccharide content may help lower cholesterol levels and improve cardiovascular function.

Stops Bleeding and Promotes Healing
Used in traditional contexts for bleeding hemorrhoids, nosebleeds, or blood in the stool, particularly due to heat in the blood.

How to Use Black Fungus

In Soups and Stir-Fries
Soak 3–10 grams of dried black fungus in water for 30 minutes until soft, then simmer in soups with goji berries, Chinese dates, or lean meats—or stir-fry with garlic and vegetables.

In Cooling Broths or Lung Tonics
Combine with lily bulb, pear, or snow fungus for a yin-nourishing dessert soup that relieves dry throat or coughing.

As a Functional Ingredient
Use soaked fungus in salads, hotpots, or noodle dishes to add texture and increase fiber without overpowering flavor.

Are There Any Side Effects?

Black fungus is very safe when soaked and cooked properly. It should not be consumed raw or in excess, as it contains small amounts of natural anticoagulants. Individuals taking blood-thinning medication should consult a healthcare provider before regular use. Spoiled or improperly dried fungus should always be discarded.
