Thank you for the informative tweet on tea contamination.

Do you know if herbal teas (e.g., lemon ginger, peppermint) have been studied or are safe? Thanks!

The potential exists for any plant and there are several factors that contribute. Yes, some herbal teas have been found to be contaminated too.

Thanks, Jeff. Guess if I want hot tea, I'm down to hot water with a slice of lemon, or maybe a hot cup of home made veggie broth (your recipe is great).
