Rooibos. 

Choice Organic Teas - Rooibos Red Bush Tea Caffeine Free. Warm yourself to the core with this earthy favorite. Rooibos is a caffeine-free herb native to South Africa, where it's been embraced for its restorative qualities for centuries. Choice Organic's russet-hued cup stands apart with a richness that suggests vanilla and honey for a delicious way to relax. Allow just-boiled water to cool for several minutes. Pour over one tea bag per cup and steep for 4-6 minutes for flavor to infuse. Sweeten as desired. For caffeine-free organic iced tea, brew double strength and serve over ice.
