Hell broths can be used to describe a mixture of unpleasant liquids. However, there are many synonyms that can be used to avoid repeating the same phrase. Instead of hell broths, one may use terms like maelstrom or noisome brew. Other phrases that can be used include fetid mixture, toxic elixir, and malodorous potion. These descriptions can be used to describe a foul smelling or vile concoction of substances. By using different synonyms, the writer or speaker can provide a more vivid and descriptive account of the content of the hellish brew without resorting to using the same phrase repeatedly.
