In 1998, we (von Hippel & von Hippel 1998) suggested that the advent of Viagra might take some of the market pressure off a variety of threatened species used to treat erectile dysfunction (ED) in traditional Chinese medicine (TCM). In 2002, we (von Hippel & von Hippel 2002) followed up this initial suggestion by providing a more complete analysis of the species that might benefit if TCM consumers switched to Viagra, and we also provided preliminary evidence that the harvest of a few species used in TCM may have already declined due to the availability of Viagra.
