Most studies (77%) had a low risk of bias.
Based on 2 RCTs showing improvements in memory and response times. One study used snow fungus in combination with other ingredients, limiting specificity to Tremella alone. Adverse event rates were similar across groups (35-41%).
Based on 3 meta-analyses of sepsis patients. One study showed RR 0.60 for mortality reduction, but another showed increased risk (RR 1.21). Evidence quality rated as low to very low. Effect limited to intravenous administration in critically ill patients.
AI-estimated from published studies. Interpret as directional guidance.
