Toxicity：

Isolated from coal oil and used in the manufacture of coumarone-indene resin. This resin is used in paints, glue, etc. and is allowed in food packaging. Little is known about the toxicity of benzofuran to humans but acute toxicity in experimental animals involves liver and kidney failure. Chronic toxicity to animals involves damage to the liver, kidneys, lungs, and stomach. Lifetime administration (oral administration) caused cancer in both rats and mice.
