In a small saucepan, bring ½ cup water to a gentle boil. Remove the water from heat, add the tea bag, and let it steep for 4 minutes. Before removing the tea bag, squeeze any water remaining out by pressing the tea bag against the side of the pan with the back of a spoon.
Add the milk, pumpkin purée, maple syrup, pumpkin spice blend, vanilla, and salt to the pan. Whisk in the optional arrowroot starch or cornstarch, if using. Pour the mixture into a stand blender and blend for a minute or two, until the components are blended together and the drink is nice and creamy. (You can alternatively use an immersion blender, but I had much better results with my stand blender.)
Pour the mixture back into your pan and gently rewarm on the stove, then pour it into a mug. Top with optional whipped coconut cream and/or garnish with a cinnamon stick or star of anise.
