Combine the first five ingredients in a spice grinder or mortar with pestle and crush or roughly and briefly chop them.
Add them to the water in a saucepan and bring to a boil; cover and lower the heat, simmering for 10 minutes. (This step may also be done in the microwave oven.)
Remove from the heat. Add the teabags, cover again and allow to steep without added heat for 10 minutes.
Strain the mixture, discarding the solids and the teabags.
Add the honey and vanilla to the concentrate.
To serve, dilute with an equal amount of milk and heat as desired on stove top or in microwave. May be diluted more or less according to preference.
