Dried black fungus is safe to consume
Before consuming dried black fungus, it should be soaked and cooked thoroughly to eliminate potentially harmful bacteria. Boiling the fungus may increase its antioxidant activity. Dried black fungus should be reconstituted in warm water for at least one hour before cooking, as it expands 3–4 times in size during this process. It can then be added to soups, stir-fries, or minced and added to stuffing to give a textural intrigue and Asian flavour.

The fibre content promotes healthy digestion and the growth of beneficial gut bacteria, while the potassium regulates blood pressure and lowers the risk of stroke.

However, it is important to consume dried black fungus in moderation, as excess consumption may lead to potential health risks. One of the primary risks associated with eating black fungus is its high oxalate content, which can contribute to the development of kidney stones in some individuals.
