Remove the water from the heat and add the red raspberry leaf, alfalfa, nettle, and dandelion leaf.
Allow the herbs to steep for 10-20 minutes.
Strain the tea and add it to a slow cooker, discarding the herbs.

Peel the oranges and divide them into sections.
Poke the cloves into the orange sections.
Add the clove-studded orange sections to the slow cooker with the herbal tea.
Add the cider, juices, cinnamon sticks, nutmeg, and ginger to the slow cooker.
Stir and heat for at least one hour.
