Rhetorical concepts can be seen as tools of the trade that allow rhetoricians to effectively communicate in a way that is most likely to persuade readers and audiences of the messages and meanings intended by the rhetorician. Rhetorical concepts are an important part of what makes an argument persuasive, and all effective arguments inherently contain them. Rhetorical concepts help rhetoricians convey information that would otherwise be unascertainable by the audience, which is especially important for topics that carry heavy implications, such as the complications that often follow complex medical and health needs.[48]
