Colchicine is used for gout despite dosing issues concerning its toxicity. Wikipedia notes:
On July 29, 2009 U.S. Food and Drug Administration (FDA) approved colchicine as a monotherapy for the treatment of familial Mediterranean fever and acute gout flares, and gave 7-year marketing exclusivity to URL Pharma, in exchange for URL Pharma doing 2 new studies. URL Pharma raised the price from $0.09 per pill to $4.85, and sued to remove other versions from market.
The written description of colchicum for gout goes back to 1500 B.C. Wikipedia also notes: Colchicum was brought to America by Benjamin Franklin; Franklin suffered from gout himself.
