The key points for identification are as follows:
Detecting dimensions
High quality features
Poor quality/adulteration characteristics
Thick earlobe, with dense gray white fur on the back
Earpieces are thin and brittle, with sparse fuzz or smooth treated with magnesium sulfate
Natural black brown, translucent dark brown red
Black shiny (possibly stained with pigments) or pale (sulfur smoked)
1: 12 (3 hours of cold water), ear pads have strong elasticity
1: Below 8, fragile or gelatinous
No change in blue when encountering iodine (no starch adulteration)
Blue color (mixed with corn starch)
Soaking water pH 6.2-6.8 (natural weak acid)
PH<5 (sulfur fumigation) or>7 (alkali treatment)
Lead content<0.5mg/kg (national standard ≤ 1.0)
Excessive cadmium/mercury (from poor quality production areas)
≥ 65% (hot water extraction method)
≤ 40% (doped with other colloids)
ORAC value ≥ 8000 μ mol TE/100g
≤3000μmol TE/100g

Antioxidant capacity
• Anticoagulation
Containing adenosine (with a content of up to 12mg/100g), the inhibition efficiency of platelet aggregation is comparable to aspirin (confirmed by Thrombosis Research), but the action time is extended by three times.
• Improvement of iron deficiency anemia
Every 100g of dried fungus contains 97.4mg of iron (6 times that of pig liver), which, when combined with vitamin K₂ to promote iron absorption, has been clinically shown to increase hemoglobin by 15% after continuous consumption for one month.
• Hypolipidemic mechanism
The combination of polysaccharides from Auricularia auricula and bile acids increases cholesterol excretion by 40%. Experiments conducted by Peking University School of Medicine have shown that 10g of dried Auricularia auricula per day can reduce LDL18%.
• Glycemic control
Water soluble dietary fiber (β - glucan) delays sugar absorption and reduces postprandial blood glucose peak by 23% (GI value is only 35).
3.Detoxification and detoxification• Heavy metal adsorption
The unique acidic heteropolysaccharides can form chelates with lead, mercury, etc. Animal experiments have shown that the lead removal efficiency is 1.7 times that of EDTA.
• Dust removal
Glial components form a protective film on the surface of alveoli, and coal miners who consume it continuously for 3 months experience a 31% reduction in lung dust deposition.
4.Immune enhancement• Intestinal immune activation
Auricularia polysaccharides promote the proliferation of Peyer's patches lymph node cells and increase sIgA secretion by 2.3 times (Immunology journal data).
• Antiviral properties
Sulfated polysaccharide inhibits the binding of S protein of COVID-19 to ACE2, with IC50 value of 37 μ g/mL (the latest research in Virology in 2023).

Core Differences
Preferred audience
Polysaccharide content 72%, ear patch thickness 1.2mm
Cancer patients undergoing radiotherapy and chemotherapy
Dietary fiber 68%, foaming rate 1:15
Constipation/high three population
Adenosine content 18mg/100g
Cardiovascular disease patients
Xiaowan Ear
Autumn fungus
Black fungus
• Health dose: 5-10g of dry food per day (about 60-120g after soaking)
• Therapeutic dose: 15g per day (under the guidance of a physician, halved when combined with anticoagulants)
2.Efficiency enhancing compatibility• Vascular cleaning: Auricularia auricula+nattokinase (synergistic anticoagulant, twice the effect)
• Detoxification package: Auricularia auricula+Spirulina (increased heavy metal excretion rate by 55%)
• Iron supplementation combination: Auricularia auricula+fresh jujube (vitamin C promotes non heme iron absorption)
3.Taboo Warning• Preoperative/menstrual period: Stop eating 3 days in advance (anticoagulant risk)
• Spleen and stomach deficiency cold: cooking with ginger shreds/Sichuan peppercorns in combination
• Safe soaking: Refrigerate soaking for ≤ 4 hours, avoid overnight use (inhibits the growth of coconut pseudomonas)
