hi if your making this from scratch the your putting in to much ginger if this is the first time for making it it takes time for you body to adjust top ginger. i make ginger and lemon tea and take it with honey i fine great frozen ginger the size of a hens egg put this in a cup with a slice of lemon micro wave 30 sec mix and pore on tea add honey so perhaps the honey cuts the heat in the throat its the heat from the ginger that is given you your problem. do hope this helps. good luck ps if its still to much just cut the amount of ginger back.
why does ginger root tea burn my throat
