Comfrey ointments have been used to heal bruises as well as pulled muscles and ligaments, fractures, sprains, strains, and osteoarthritis. In the past, comfrey was also used to treat stomach problems. However, it has toxic substances called pyrrolizidine alkaloids that damage the liver and can lead to death. Comfrey is no longer sold in the U.S., except in creams or ointments. The United Kingdom, Australia, Canada, and Germany also have banned the sale of oral products containing comfrey.
Some of the most toxic waste substances produced by metabolism are small nitrogen-containing compounds called nitrogenous wastes. About 50 % of nitrogenous waste is urea, a by-product that is produced when protein is broken down by the body.Protein is broken down into amino acid and some of it forms ammonia, which is very toxic. The liver, however, quickly converts it to urea, which is a less harmful waste.bout 50 % of nitrogenous waste is urea, a by-product that is produced when protein is broken down by the body.
