Cultivation and uses

The leaves are sometimes used as a substitute for tea in China, and the fruit are edible, though not an important crop. S. theezans, from southern China, is a popular species in bonsai. S. paucicostata, from northern China, is the most cold-tolerant species and is occasionally grown in gardens in Europe and North America, though it is not generally considered very attractive as an ornamental plant. It is reputedly used as a way of cleaning minor cuts and lacerations, ensuring any germs left over will not infect the wound. When ground up and mixed with salt, it forms a minor explosive capable of shattering glass.
