If you like Bengal Spice tea check out Good Earth Spice Tea. I am not sure if it is Whole30 compliant because I don't have any at the moment. If not try it after your whole30. It is similar to bengal spice.
I have this Bengal Spice herbal tea from Celestial Seasonings. It honestly tastes deliciously sweet that i feel like there must be something amiss.
Here are the ingredients:
"Cinnamon, roasted chicory, roasted carob, natural spice and vanilla flavors with other natural flavors, ginger, cardamom, black pepper, cloves and nutmeg." from - http://www.celestialseasonings.com/products/herbal-teas/bengal-spice
Is this Whole30 compliant? Or should I avoid because of the "other natural flavors"
Searching the "Can I have guide" it looks like Melissa posted a comment yesterday stating that natural flavors are not technically off program. However natural flavors can mean a lot of things so you may want to consider what it means to you personally in regards to your W30. In other words this is a personal preference area as far as I can tell.
