Review on Research Progress and Prospects of Cicada Flower, Isaria cicadae (Ascomycetes).

Cicada flower, Isaria cicadae Miq., has been a traditional Chinese medicine for approximately 1600 years. Many works on its identification, bioactivities, and clinical use against some disorders have been published, but some inaccuracies and inconsistencies need to be further clarified. In combination with our > 20 years of research and application of cicada flower and examination of the literature and patents published in recent years, this article summarizes and reviews the life cycle and taxonomy, genome size and mating type, molecular systematic classification and cultivation, active ingredients, and pharmacological functions of I. cicadae.
