In a medium-sized pot, start by heating 4 cups of water to a boil. Make sure the pot is spotless and free of any dirt or debris.

While the water is boiling, peel and slice 2 red onions into thin pieces. The slices should be approximately 1/4 inch thick. This will help release the flavors and nutrients into the tea effectively.

Add the red onions, cut into slices, to the saucepan once the water has come to a rolling boil. The mixture should steep for about 15 minutes once the heat is reduced to a simmer. This will allow the flavors and nutrients to infuse into the water.

After steeping, you can strain the tea to remove the onion slices if desired. Add honey or lemon to taste for a touch of sweetness and a tangy twist. If you prefer a spicier flavor, consider adding a pinch of cinnamon or ginger.
