Also: gum camphor
A strong-smelling solid used in chest rubs and as a moth-and-mouse deterrent. It is toxic if eaten, and it is a fire risk next to oxidizers.
Prefer finished commercial rubs over mixing raw camphor. If you store the raw gum, treat it like a solvent: sealed, labeled, out of reach.
Pharmacy USP blocks. Do not buy mystery mothballs — many are naphthalene or paradichlorobenzene, different toxins.
