Courtney, you can definitely use
regular black tea bags and it will be great — shaking it up will not emulsify it the same way that a blender will (meaning it is not going to be as completely mixed up), but I think it would still be good.
Personally, I mix a teaspoon of ground organic green decaf
tea a teaspoon of hibiscus powder and 1
bag of
regular organic green
tea and boil it keeping a close eye on it so it doesn't overflow, then put it into a glass with some cooler water, add a teaspoon of; turmeric, gooseberry powder, barberry powder, berberine extract,
black pepper, and a couple of teaspoons of coffee.
