Ingredients

1/2 cup baking soda
1 lemon, thinly sliced - reserve a couple of slices for foot bath
1 bunch of fresh mint, finely chopped

Equipment:

Medium bowl, 12" square of cheesecloth or a large coffee filter, rubber band

Instructions:

In a square of cheesecloth, or in coffee filter, loosely pack in sliced lemons  and chopped
mint  Fill bowl with hot water, and steep "sachet" for 5 minutes.  Fill a foot bath with cool
water,  and swirl baking soda in.  Add lemon-mint "tea" squeezing the sachet to remove
as much as possible.  Add reserved lemons, and soak feet for ten minutes. 

This is a remarkable  "pick-me-up", especially if feet are overworked and hot.  The
'tea' can be prepared up to 24 hours ahead and chilled, before use, too.
