Stomach Trouble Tea

My father has frequent bouts of stomach ailments. To help ease him through this I make him this tea:
1 Tbs Chamomile (dried aerial parts)
3 cloves
1 cup of boiling water
1-2 tsp of honey
1 tsp of slippery elm
1/4 tsp of ground cinnamon

place chamomile and cloves (you may want to bruise them first) into a tea ball or infuser. Pour over the boiling water and let steep 3-5 minutes. After removing tea ball, add honey to taste, then stir in slippery elm until dissolved. (Note that the slippery elm may drift to the bottom if you let it sit to cool, stir up before drinking). Stir in cinnamon. Sip.
