Liquorice (and liquorice tea) contains glycyrrhizin. This substance, which gives liquorice its characteristic taste, causes a rise in blood pressure.
Glycyrrhizin is converted into glycyrrhetinic acid in the gastrointestinal tract, as a result of which the body retains more fluid. This effect temporarily increases blood pressure, but if large quantities of liquorice are consumed on a regular basis, blood pressure may also be raised over the long term.
