Ephedra comes from the dried rhizome and root of the plant. The main active ingredients in ephedra are ephedrine and pseudoephedrine which account for the medicinal properties of the herb. Both ephedrine and pseudoephedrine are central nervous system stimulants that act as decongestants but, in high doses, can raise the blood pressure.
Definition of Epistrophe. Epistrophe is a figure of speech that involves the repetition of a word or phrase at the end of successive clauses or sentences. Epistrophe is also known as epiphora or antistrophe. The word epistrophe comes from the Greek for âreturn.â. The definition of epistrophe is opposite to that of anaphora, which is the repetition of words at the beginning of successive clauses or sentences. When an author combines epistrophe with anaphora, i.e., repeats words or phrases at both the beginning and end of successive clauses, this is called symploce.
