question: Worker: Tej is a mead or honey wine that uses a flavoring agent that is similar to what flower that is used in herbal medicine?
answer: Hops
context: Title: Herbalism
  Passage: Herbalism (also herbal medicine or phytotherapy) is the study of botany and use of plants intended for medicinal purposes or for supplementing a diet.  Plants have been the basis for medical treatments through much of human history, and such traditional medicine is still widely practiced today.  Modern medicine recognizes herbalism as a form of alternative medicine, as the practice of herbalism is not strictly based on evidence gathered using the scientific method.  Modern medicine makes use of many plant-derived compounds as the basis for evidence-based pharmaceutical drugs. Although phytotherapy may apply modern standards of effectiveness testing to herbs and medicines derived from natural sources, few high-quality clinical trials and standards for purity or dosage exist.  The scope of herbal medicine is sometimes extended to include fungal and bee products, as well as minerals, shells and certain animal parts.
  Title: Tej
  Passage: Tej (Amharic: , pronounced ] ; Tigrinya: ሜሰ , Oromo: "daadhi" ) is a mead or honey wine that is brewed and consumed in Ethiopia and Eritrea.  It is flavored with the powdered leaves and twigs of "gesho" ("Rhamnus prinoides"), a hops-like bittering agent that is a species of buckthorn.  Tej is usually homemade, but throughout Ethiopia it is available in "tej houses" ("tej betoch", singular "tej bet" (Tigrinya: ጠጅ ቤት )).
  Title: Hops
  Passage: Hops are the flowers (also called seed cones or strobiles) of the hop plant "Humulus lupulus."  They are used primarily as a flavoring and stability agent in beer, to which they impart bitter, zesty, or citric flavours; though they are also used for various purposes in other beverages and herbal medicine.  The hop plant is a vigorous, climbing, herbaceous perennial, usually trained to grow up strings in a field called a hopfield, hop garden (nomenclature in the South of England), or hop yard (in the West Country and U.S.) when grown commercially.  Many different varieties of hops are grown by farmers around the world, with different types being used for particular styles of beer.
