做法1:
Parsley Tea
Cut the leaves off of the stem of parsley (do NOT use the stems. This will make the tea extremely bitter). Cut enough until you have a big handful of leaves. Put into a medium sized pot with a quart of water and bring to a boil. Boil for 5 minutes. Strain, pour into a pitcher or glass jar and refrigerate. Serving size will depend on the size of your animal, but we put 1 tsp. into my cat’s food every time we fed him, and we mixed 3 tsp. into his water dish every time we refilled it.
