Can dogs drink rooibos tea

I have found on www.innvista.com, in their article on Rooibos that it "stands head and shoulders above the rest as an all-round healthy alternative". Rooibos does not have caffeine in it, and contains 37 powerful antioxidants which strengthen the immune system. It also has a natural sweetner in it so you do not need to put sugar with it. So yes, you can give your dogs rooibos tea its actually good for them;)
