The wood has a density of about 0.75 g/cm³.[4] In Taiwan, its wood was used to make support beams for underground mines. The wood is also converted to charcoal for family use. The plant is used in traditional medicine[5] and is available from herbal medicine shops (草藥店) in Taiwan, but there has been no clinical study to support its effectiveness. It is also frequently used as a durable flooring material.
