Black Fungus

In plain English, Black Fungus (also called Wood Ear or Jelly Ear) is that dark, floppy, ear-shaped mushroom you've probably encountered in Chinese hot and sour soup, moo shu pork, or a stir-fry at your local Asian restaurant. It has an incredibly distinctive texture — crunchy, slippery, and slightly chewy all at once — that adds a satisfying bite to dishes. The flavor is very mild, almost neutral, which means it takes on the flavors of whatever sauce or broth it's cooked in.

What makes Black Fungus medically interesting is its traditional reputation as a blood health mushroom. In Chinese medicine, it's been used for centuries to "invigorate the blood" and promote healthy circulation. Modern research has begun to validate this traditional use: studies have identified polysaccharides in Black Fungus with anticoagulant properties — meaning they may help prevent blood from clotting too readily. This has led some researchers to call it a natural blood thinner, though it's important to note that anyone on blood-thinning medication should consult their doctor before consuming large amounts.

Black Fungus is also notably high in iron — one of the richest plant-based sources available, which makes it particularly valuable for vegetarians, vegans, and anyone prone to iron deficiency. It's rich in dietary fiber that may support gut health and cholesterol management, and its polyphenols provide antioxidant protection. Traditional Chinese Medicine practitioners have long recommended it for supporting cardiovascular health, maintaining healthy blood pressure, and aiding digestion.

In the kitchen, Black Fungus is incredibly easy to work with. Dried Black Fungus is inexpensive and available at virtually any Asian grocery store. Simply soak the dried pieces in warm water for 20 to 30 minutes — they'll expand dramatically, sometimes to five or ten times their dry size. Once rehydrated, they're ready to slice and toss into soups, stir-fries, salads, spring rolls, or noodle dishes. They hold up well to cooking and maintain their signature crunch even in hot broths.

As a supplement, Black Fungus is less commonly available than mushrooms like Lion's Mane or Reishi, but you can find it in capsule form and occasionally in mushroom blend products focused on cardiovascular support. Most people simply incorporate it into their diet as a whole food, which is easy given its affordability and wide availability. Typical dietary intake in Asian cuisines is about 5 to 15 grams of dried fungus per serving, rehydrated before cooking.

When buying dried Black Fungus, look for pieces that are uniformly dark, dry, and free from debris or unusual odors. Store dried Black Fungus in an airtight container in a cool, dry place where it will keep for months or even years. Once rehydrated, use it within a day or two. As with any blood-affecting food, moderation is key — enjoy it as part of a varied diet rather than consuming very large amounts daily, especially if you're taking anticoagulant medications.
