In areas where Japanese barberry is invasive, it promotes in humans the terrible and difficult-to-treat ⚕︎ Lyme disease, for reasons having something to do with disease vectors deer  family Cervidae, white-footed deer mice  Peromyscus leucopus, black-legged deer ticks  genus Ixodes, and the Lyme disease bacterium  Borrelia burgdorferi.

In the 🇺🇸 USA, the USDA suggests those seeking a shrub with nice fruit replace this plant with native alternatives 🍓︎ strawberry bush  Euonymus americanus, wax-myrtle  Myrica cerifera, meadowsweet  Spiraea latifolia or mapleleaf viburnum  Viburnum acerifolium. [2]   And the Lehigh Gap Nature Center suggests those seeking scented flowers and nice fall color replace this plant with native alternative Virginia sweetspire  Itea virginica. [3]   More native alternatives (Missouri Botanical Garden).   And a buddy of our JG recommends alternative pricklyash  Zanthoxylum americanum.
