Place the tea bags, water, vanilla extract, star anise, cardamom, cinnamon stick, vanilla bean, and turmeric into a medium-sized pot and bring to a simmer over medium heat. Reduce the heat to low and let simmer for 3 to 5 minutes.
Pour the tea mixture through a strainer to remove the whole spices. Fill two glasses with ice and pour the tea over the ice.
In a small bowl whisk the sweetened condensed milk and evaporated milk (or whole milk) together until smooth.
Pour the milk mixture over the iced Thai tea. Garnish with mint leaves.
