Comparison
Lion's Mane vs Polygala (Yuan Zhi)
Lion's Mane
Hericium erinaceus, a medicinal mushroom whose hericenones and erinacines stimulate Nerve Growth Factor (NGF) production. Unique among nootropics for its peripheral nerve regeneration mechanism. Effects build over 4–8 weeks; choose dual-extract (water + ethanol) forms with verified beta-glucan content.
Polygala (Yuan Zhi)
Chinese herb (Polygala tenuifolia) traditionally used for memory, sleep, and emotional balance. Modulates serotonin and acetylcholine.

Bottom line
Lion's Mane (evidence B, safety 5/5) has a weaker evidence base than Polygala (Yuan Zhi) (evidence C, safety 4/5). Lion's Mane has the slightly cleaner safety profile. For users new to either, the higher-evidence option is the safer first try.
Choose Lion's Mane if
Lion's Mane is the better fit when your goal aligns with its mechanism (Hericenones (from the fruiting body) and erinacines (from the mycelium) stimulate NGF synthesis in vitro and in vivo) and the dose range (500–3000mg) suits your protocol. Half-life is 8h.
Choose Polygala (Yuan Zhi) if
Polygala (Yuan Zhi) is the better fit when your goal aligns with its mechanism (Tenuifolin and onjisaponin B inhibit acetylcholinesterase) and the dose range (200–600mg) suits your protocol. Half-life is —h.
