crystallized tree blood that grips violin strings and saves a pitcher's slipping fingers
means Rosin is the solid, brittle resin left after distilling the volatile oils out of pine sap, used to add grip to surfaces like bow hair, athletes' hands, and string instruments.
from Rosin is just "resin" with its vowels shuffled — both come from the Latin resina, the gummy stuff that weeps from trees, which passed through Old French into English. Somewhere along the way the spoken word wandered, and the same tree-sap term split into two: "resin" for the substance in general, and "rosin" for the hardened, purified form rubbed onto bows and fingers.
