All these toxins produce free radicals, which cause cell damage. They can, however, be neutralized by substances called antioxidants. Thus, milk thistle acts as an antioxidant in the liver, protecting it from free-radical damage. Animal studies suggest that milk thistle extract can also protect against many poisons, from toluene, a common solvent, to acetaminophen, the main ingredient in Tylenol. In Europe, doctors often prescribe milk thistle as extra protection for patients taking medications that are known to case liver problems.
Milk thistle can also protect against future toxic exposure.
St. John's wort is a bushy perennial plant with yellow flowers that commonly grows wild. It is native to many parts of the world, including Europe, Asia, and the United States. It gets its unusual name from St. John the Baptist, since it was traditionally collected on St. John's Day, June 24. While St. John's wort won't take the stress away, it will help you deal with it better. The herb should be taken regularly, at the ususl doses, and not just before stressful events, since it needs to build up in the system to be the most effective.
