Marigold, Calendula officinalis, has been known, practically, from the beginning of documentary records in scientific or medicinal lines. A native of Eastern Asia, it is found under various names, from Japan to India, from the Orient to North America, where European colonists carried it, according to Josselyn (345), before 1670. In early days of English mediaeval medication it was employed in decoctions for fevers, and as a hot drink, to promote perspiration. The juice was also employed empirically for sore eyes, and as an application to warts. Its popular use, as heired from a time lost to history, led to its final utilization by the medical profession, and to its position in the mediaeval herbals, as also in many pharmacopeias and treatises on European medicines and medication.
