Liver Anagram

An anagram is a word puzzle in which you take a word and rearrange its letters and try to make as many possible new words. For instance, if I take the word live, I can rearrange the letter to form evil, vile, Levi, and veil. Attempting to form anagrams from the word liver, I came up with none. How can this be? Sure an organ with over 500 functions has at least one anagram. Please, someone show me I am wrong by coming up with at least one anagram.
