cracked up

With all this hand washing, cold weather and dry buildings, my thumbs are cracking up. Nothing works to alleviate the my sorry and painful state. But I am told that help in is the barn - "Bag Balm". I presume that it is for cows' udders. Am I right? So if they can come up with a product for cows, why not for people? I expect that it is really greasy and mostly lanolin. Am I right?  Gardening season is just a month away, and my hands will feel it, badly.
