Auricularia Hispida Mushroom
Also known as: Auricularia hispida, Ear mushroom, Wood ear, Jelly ear, Cloud ear
Overview
*Auricularia hispida*, commonly referred to as ear mushroom or wood ear, is a gelatinous fungus found in tropical and subtropical regions. It belongs to the *Auricularia* genus, closely related to *Auricularia auricula-judae* and *Auricularia polytricha*. While less studied than its relatives, *A. hispida* is consumed as food and explored for its potential health benefits, drawing from the established uses in traditional Chinese medicine. The mushroom is characterized by its ear-like shape and contains bioactive compounds such as polysaccharides, polyphenols, flavonoids, and ascorbic acid, contributing to its antioxidant properties. Research on *A. hispida* is limited, with most evidence extrapolated from studies on related species. It is primarily recognized for its antioxidant activity and nutritional content, with ongoing exploration into its potential cardiometabolic benefits. Available evidence consists mainly of in vitro and animal studies, highlighting the need for more clinical research to validate its effects in humans. It is generally considered safe when consumed as food.
Benefits
*Auricularia* species, including *A. hispida*, exhibit significant antioxidant activity, demonstrated by DPPH radical scavenging with EC50 values <50 mg dry matter/ml for *A. polytricha* and 1.62 mg/mL for *A. auricula-judae* in in vitro studies. These mushrooms also offer nutritional value, containing approximately 278–299 mg of protein, 1.96–2.43 g of lipids, and 3.93–6.11 g of ash per 100 g, depending on the strain. While direct evidence for *A. hispida* is limited, related species suggest potential cardiometabolic health benefits due to their bioactive compounds. These benefits are inferred from studies on *A. auricula-judae* and *A. polytricha*, indicating a need for specific research on *A. hispida* to confirm these effects. The antioxidant effects are robust in vitro, but their clinical significance in humans remains unclear due to the lack of randomized controlled trials.
How it works
The antioxidant effects of *Auricularia hispida* are primarily attributed to its ability to scavenge free radicals, such as DPPH and ABTS, through its polyphenols, flavonoids, and polysaccharides. These bioactive compounds interact with the body's systems to reduce oxidative stress and potentially support immune function. While specific molecular targets for *A. hispida* are not well-defined, it is inferred from related species that it may influence inflammatory mediators. The absorption and bioavailability of these compounds are not fully understood, but polysaccharides and polyphenols are likely absorbed to some extent, although high fiber content may limit their overall bioavailability.
Side effects
Consumption of *Auricularia hispida* is generally considered safe when used as a food ingredient. However, there is limited data available regarding the long-term safety of *A. hispida* as a dietary supplement. Common, uncommon, and rare side effects are not reported in the available literature. There are no known significant drug interactions, although there is a theoretical risk of additive effects with anticoagulant medications due to the polysaccharide content, which is inferred from related species. Contraindications are not established, but caution is advised for individuals with known mushroom allergies. Safety during pregnancy and lactation has not been established, and therefore, use should be approached with caution in these populations.
Dosage
Due to limited research on *Auricularia hispida*, minimum effective and optimal dosage ranges are not established. Typical culinary use involves 5–10 g of dried mushroom per serving. The maximum safe dose is also not established, but no toxicity has been reported at culinary doses. There are no specific timing recommendations for consumption. *A. hispida* can be consumed in dried or fresh form, and extracts have been used in research settings. The high fiber content of the mushroom may limit the bioavailability of some compounds. No specific cofactors are identified as necessary for its activity.
