I experimented and tried making some tea that Yoga Yoga serves after class. They helpfully provide the recipe here. I have copied it down here just in case it might disappear.

• 2 quarts water
• 15 whole cloves
• 20 black peppercorns
• 3 sticks of cinnamon
• 20 whole cardamon pods (split the pods first)
• 8 ginger slices (1/4″ thick, no need to peel)
• 1/2 teaspoon black tea leaves (we use decaf)

Bring 2 quarts of water to a boil in a 3-4 quart pot. Add cloves and boil for one minute. Next, add cardamon, peppercorns, cinnamon, and fresh ginger root. Cover and boil for at least 30 minutes. For best flavor, cover and simmer for 2 to 3 hours! When ready, remove from heat, add black tea and let cool. Strain tea. When ready to drink, add soy or dairy milk and sweeten to taste with agave nectar.

Thumbs up! It is pretty spicy! And you have to give it bonus points for using peppercorns.
