Here it says it is a legume. http://www.betternutrition.com/south-africa-rooibos-tea/columns/askthenaturopath/854

I did not put anything in it as I drink my tea plain. The only thing I had prior to drinking it is a plain piece of chicken, same chicken I have every day...

I'm a little hesitant to try it again as I am still in a major flare from it..
