Is Wood Ear Mushroom Poisonous?

The wood ear mushroom, also known as black fungus or cloud ear mushroom, is a popular ingredient in Asian cuisine.

It’s commonly used in soups, stir-fries, and salads due to its crunchy texture and subtle flavor.

However, many people wonder if it’s safe to eat raw or if it contains any toxins.

Potentially Harmful Compounds

While wood ear mushrooms are generally safe to eat, they do contain some potentially harmful compounds that can cause an allergic reaction or digestive issues in some people.

  • Triterpenoids: These compounds give the mushroom its bitter taste and can cause stomach upset in some individuals.
  • Hypoglycin A: This toxin is found in some species of mushrooms and can cause hypoglycemia (low blood sugar) if consumed in large amounts. However, it’s not present in wood ear mushrooms.

Cooking Wood Ear Mushrooms

Cooking wood ear mushrooms thoroughly is highly recommended as it helps break down the tough fibers and makes them easier to digest.

While some people may enjoy eating them raw, cooking them helps reduce the risk of any potential health issues. To cook wood ear mushrooms:

  • Rinse them under running water to remove any dirt or debris.
  • Soak them in warm water for 15-20 minutes until they become soft and pliable.
  • Cut into small pieces or leave whole depending on your recipe preference.
  • Stir-fry or cook with other ingredients until fully cooked (about 5-10 minutes).

Poisonous Look-Alikes

It’s important to note that there are poisonous fungi that resemble the wood ear mushroom.

The most well-known is the false morel mushroom.

Unlike the smooth surface of the wood ear mushroom cap, false morels have a wrinkled cap with brain-like folds on its surface.


In conclusion, while raw wood ear mushrooms may be safe to eat for some individuals, it’s highly recommended to cook them before consumption due to their tough texture and potentially harmful compounds.

Additionally, be sure to properly identify any fungi before consuming as there are poisonous look-alikes out there that can cause serious harm.
