Combine 2 cups (480ml) water with cinnamon stick, star anise, cloves, and cardamom pods in a saucepan. Bring to a boil, reduce heat, and allow it to simmer for at least 5 minutes. The longer you simmer, the stronger the flavor of the spices.
Turn off the stove and remove saucepan. Drop in the teabags and allow them to steep for 5 minutes.
In the meantime, bring coconut milk and sugar in a small saucepan over medium low heat to a bare simmer. Stir to dissolve sugar. Remove.
When tea is ready, remove teabags and cinnamon stick. Strain the tea into 2 mugs.
Froth or whisk coconut milk for a few seconds or until frothy. Immediately pour frothy coconut milk into each of the mugs with tea.
