About this ingredient
Japanese loquat (Eriobotrya japonica) — Nagasaki and Chiba produce the principal commercial fruit supply; the leaves have substantial Kampo herbal use. Distinguished from imported loquat by superior fresh-fruit eating quality. Cosmetic-grade biwa-leaf extract (existing glossary slug 'eriobotrya-japonica-leaf-extract') anchors anti-inflammatory and skin-calming positioning. Distinct from existing food / herbal entries.
