Uses
The roots in particular have numerous medicinal uses in Indo-China; they are also used in Chinese medicine. Young shoots are cooked and eaten as a vegetable. The red fruits can be used to colour wine and foods, but the toxic substances must be removed. P. americana is a common ornamental in temperate climates.
