I did some looking into what made black licorice taste so good and to see if enjoying it was genetic. I was surprised to find out it can be toxic. All of these years my grandfather and I have been poisoning each other. Guess we should celebrate we survived it with a pint of sarsaparilla.
Everything is toxic in high enough quantities.
> If you’re 40 or older, eating 2 ounces of black licorice a day for at least two weeks could land you in the hospital with an irregular heart rhythm or arrhythmia.
