Lingzhi líng zhī · 灵芝

Safety. Documented concerns: anticoagulant and antiplatelet medicines (additive bleeding risk), antihypertensive and diabetes medicines (additive lowering), and immunosuppressants (theoretical antagonism). Stop well before scheduled surgery. Cases of liver injury have been reported with lingzhi preparations including spore powders; a causal relation is not established. The species actually sold is often not the species named — Ganoderma lingzhi, G. lucidum and other Ganoderma are traded under one common name, so two products are rarely comparable. Long-term safety data are limited. Safety in pregnancy and breastfeeding has not been established. Persistent insomnia, chronic cough or unintended weight loss is not a self-treatment matter — see a licensed clinician.
