Chamomile is another popular remedy for calluses. This herb has a soothing effect on the skin and its anti-inflammatory properties help reduce the discomfort. Brew one to two cups of chamomile tea. Fill a small foot tub with some water and add the chamomile tea to it. Soak your feet in this soothing water for 10 minutes. Do this daily for a few days in the evening before going to bed. This will help keep your feet moisturized overnight.
