Place a tea strainer in a mug and add the ginger. Pour boiling water over the ginger. Allow to steep for up to 10 minutes.
After the ginger has been steeping for about 7 minutes add the green tea to the strainer. Green tea should steep for no more than 3 minutes.
Remove strainer. Compost or discard the ginger and tea/tea bag.
Add apple cider vinegar and lemon juice. Stir in honey if including.
This could be made with dried, powdered ginger if it's fresh, but the medicinal quality of any herb degrades over time. The fresher the better for this recipe! (Aka your results may be disappointing if you use powdered ginger that has been in your spice drawer for years.)
