An eggshell is the outer covering of a hard-shelled egg and of some forms of eggs with soft outer coats. Bird eggshells contain calcium carbonate and dissolve in various acids, including the vinegar used in cooking. While dissolving, the calcium carbonate in an eggshell reacts with the acid to form carbon dioxide.
The membrane of the shell is reported to help promote healing in cuts and scratches.
If you cut your finger, simply wrap the membrane around it to protect it from becoming infecting, as well as for speeding up the healing process.
