A traditional Chinese medicine “sang ji sheng” is made from this taxon. Recorded hosts include Camellia oleifera, Cinnamomum camphora, Morus alba, and species of Quercus and Salix. Collections from Taiwan with rather longer flowers (1.7–2.3 cm) and tips of buds more or less acute have been treated as Taxillus lonicerifolius var. longifolius.
