I did further readings about Liquorice and I find something significant on its toxicity. I hope this helps, so be extra careful.
Excessive consumption of liquorice or liquorice candy is known to be toxic to the liver and cardiovascular system, and may produce hypertension and oedema. There have been occasional cases where blood pressure has increased with excessive consumption of liquorice tea, but such occasions are rare and reversible when the herb is withdrawn. Most cases of hypertension from liquorice were caused by eating too much concentrated liquorice candy. Doses as low as 50g daily for two weeks can cause a significant rise in blood pressure.
Licorice (the herb not the candy) cannot be taken safely for very long. It causes high blood pressure. I have found licorice root in diet teas and women's remedy teas used as a dieretic. Taken any longer than 6 days or so can cause health issues. I made the mistake years ago of drinking a dieter's tea after my evening meal for over a year. I had never had a problem with high blood pressure before but after a year on that tea my blood pressure sky rocketed and I felt horrible. As soon as I stopped the tea my blood pressure went back down to normal.
