About
蛔 is a phono-semantic compound: the radical 虫 (insect) places it in the category of worms and similar creatures, while 回 (huí) indicates its pronunciation. The character specifically denotes the parasitic roundworm, Ascaris lumbricoides, an intestinal parasite infecting humans and animals. It is the simplified form of 痐, which originally used the sickness radical 疒 to emphasize the disease aspect; simplification replaced it with 虫 to directly represent the worm itself.
