But I had that open crack in my thumb for several years, no matter what I did. Until one day I took a couple of capsules of flax oil. The very next day the fissure had closed up and was healing. First time in years.

Since then I have used Flax oil for heel cracks with the same results. I should have learned by now to take it regularly, but I get lazy.
