Has to be made from true licorice root. most of today's black licorice is made from artficial flavouring or anise seed extract.

Most black licorice flavoured candies on the market use the cheaper anise seed. Good licorice that might cost $8-10 for a 10-12 oz bag will sometime use the real stuff. I keep a jar of actual licorice root on hand for colds.
The decent brands of licorice do use licorice root extract. Like Panda or Darrell Lea. They say they add around 0.5% licorice extract, but it's all relative to the concentration of glycyrrhizic acid in the extract. That's the compound you may need to worry about.
It doesn't sound like much because even Panda says "there's a small amount of glycyrrhizic acid,"
in their FAQs, but they never actually tell you how much. That's on purpose.
"Panda licorice is an authentic licorice product. The key ingredient in Panda licorice is licorice extract, which is made from wild growing licorice root naturally containing small amounts of glycyrrhizin"
If you're adding 0.5% weight by volume of licorice extract to an 8oz bag of licorice with a 20% glycyrrhizic acid concentration, that's 200mg/ml.
Add approximately 1.2-1.3 mls of extract per 7-8oz bag and that's about 250 mg of glycyrrhizic acid in each bag.
That seems to be in line with what I found online.
"Manufacturers list licorice extract or glycyrrhizic acid in the ingredient list. According to the WHO, up to 100 mg per day of glycyrrhizic acid, equal to about 2–2.5 ounces (60–70 grams) of licorice, is safe for the majority of adults.Jan 12, 2022"
