Wood Ear Mushroom Benefits the Heart, Immunity & More

Wood ear mushroom - Dr. Axe

Although once used solely in traditional forms of medicine, more and more research has started to reinforce the incredible benefits of mushrooms. In fact, certain varieties have been linked to many impressive health benefits, ranging from lower cholesterol levels to decreased cancer growth and more. The wood ear mushroom, in particular, is an ingredient that  has become increasingly popular in stir-fries and soups. Not only does it bring a crisp, snappy texture to meals, but it’s also jam-packed with an assortment of important nutrients and antioxidants.

So what are wood ears in Chinese cooking? And how can these medicinal mushrooms impact your health? Here’s what you need to know.


What Are Wood Ear Mushrooms?

Wood ear mushrooms are a tasty and unique type of edible fungi that go by a number of different names, including Chinese wood ear mushroom, black mushrooms, jelly ear mushrooms or their scientific name, Auricularia auricula-judae.

These mushrooms stand out from other mushroom varieties because of their crunchy texture, dark color and interesting appearance. Unlike other mushrooms, wood ear mushrooms don’t have a stem or cap. They do have an ear-like shape, which is how they originally earned their distinct nickname. However, they are still sometimes confused with the white wood ear mushroom and the elephant ear mushroom, as well as cloud ear fungus (kikurage mushroom), another type of edible tree mushroom that is distantly related to the wood ear.

The black wood ear mushroom is often featured in Asian cooking and widely enjoyed for its crisp texture and mild flavor. So what does black fungus taste like? Although they have a strong woody flavor when raw, the mushrooms tend to take on whatever flavors they are cooked with in dishes, making them a great addition to soups, stir-fries and salads.


Wood Ear Mushroom Nutrition Facts

Wood ear mushrooms are a great source of many important vitamins and minerals. In fact, each serving contains a low amount of wood ear mushroom calories but is packed with copper, pantothenic acid, selenium and riboflavin.

One cup (about 99 grams) of raw wood ears contains approximately:

  • 25 calories
  • 7 grams carbohydrates
  • 0.5 grams protein
  • 0.5 milligrams copper (56 percent of the DV)
  • 2 milligrams pantothenic acid (40 percent of the DV)
  • 11.1 micrograms selenium (20 percent of the DV)
  • 0.2 milligrams riboflavin (15 percent of the DV)
  • 0.08 milligrams thiamine (7 percent of the DV)
  • 25 milligrams magnesium (6 percent of the DV)
  • 0.7 milligrams zinc (6 percent of the DV)
  • 0.09 micrograms vitamin B6 (5 percent of the DV)
  • 19 micrograms folate (5 percent of the DV)

In addition to the nutrients listed above, wood ear mushrooms also contain a small amount of potassium, phosphorus and calcium.


Wood Ear Mushroom Benefits

1. May Help Fight Cancer Cells

Packed with disease-fighting antioxidants, promising preliminary research suggests that dried wood ear mushroom extract could help fight the growth of cancer cells. One in vitro study conducted by Kyungpook National University in Korea found that wood ear mushroom extract was effective at killing off tumor cells of the lungs, bones and stomach. Keep in mind, though, that more research is needed to evaluate whether wood ear mushrooms may have a beneficial impact on cancer growth in humans as well.

2. Supports Heart Health

Some studies have found that wood ear fungus could have powerful hypolipidemic properties, which can help keep cholesterol levels in check and protect against heart disease. According to one animal model published in Mycobiology, administering wood ear mushroom extract to mice led to massive reductions in levels of triglycerides, total cholesterol and bad LDL cholesterol. It also decreased the atherogenic index by 40 percent, which is a measure used to predict the risk of heart disease and plaque buildup in the arteries.

3. Loaded with Antioxidants

Research shows that wood ear mushrooms are jam-packed with antioxidants and polyphenols. That can have a huge impact on overall health. Antioxidants are compounds that help fight free radical formation and protect cells against oxidative damage. Antioxidants also play a central role in health and disease, with research indicating that they could aid in the prevention of chronic conditions like cancer, heart disease and rheumatoid arthritis.

4. Blocks Bacterial Growth

In addition to being a great source of antioxidants and micronutrients, wood ear mushrooms also possess potent antimicrobial properties that can help ward off certain strains of bacteria. A 2015 in vitro study in the International Journal of Medicinal Mushrooms actually found that wood ear mushroom was effective at blocking the growth of Escherichia coli and Staphylococcus aureus, two types of bacteria that can cause infections in humans.

5. Good Source of Copper

Each serving of wood ear mushrooms packs quite a punch when it comes to nutrition. These small but powerful mushrooms are an especially good source of copper, a micronutrient that is essential to several aspects of health. Not only is copper important for iron metabolism, but it’s also needed for heart health, lung function and more. A deficiency in this key nutrient can have some serious side effects, ranging from diarrhea and impaired immunity to weakened bones, nerve damage, anemia and heart problems.


Where to Find and How to Use Wood Ear Mushrooms

Wood ear mushrooms grow worldwide and can be found on wood in cool temperatures, usually around early spring or late fall. Although they are sometimes confused with other species, most wood ear mushroom lookalikes are actually edible as well.

Besides foraging for them yourself, you can also find the mushrooms at many specialty stores and online retailers. It’s much easier to find the wood ear mushroom dried, but it can simply be reconstituted by soaking in water overnight to enjoy it fresh as well.
