Halofuginone Products | Cleanchem - Halofuginone is a drug used to treat a variety of parasitic infections, particularly in animals. It has been shown to inhibit the growth of certain protozoan parasites and is used in veterinary medicine for the prevention and treatment of coccidiosis in poultry.

Research into its use in humans for conditions like fibrosis is ongoing.
