Liquorice (there’s also an actual root, not just the confectionery) is tummy-friendly, actually recognised as a herbal remedy over here for (mild) gastritis because antiinflammatory and antispasmodic (alongside helping with coughs and having some antibacterial properties) but too much will fuck with your blood pressure. There’s some medicinal teas over here which pretty much only contain it to taste better (otherwise makes no sense in combination with e.g. valerian). The stuff is actually sweet and pleasant, not a neutral but woody sweetness, not to be confused with North European liquorice confectionery where the predominant flavour is Salammoniac. Which are also very good… hey I grew up with the stuff, don’t look at me like that.
