Make rooibos tea the night before the party by soaking 4-5 tea bags in 32 oz. of warm water. Refrigerate overnight.
The day of the party, discard tea bags and combine the rest of the ingredients in a punch bowl or pitcher. Serve over ice and garnish each drink with a mint leaf.
*Rooibus tea is also called South African red tea or just red tea and is available at most heath food stores.
