Pseudowintera colorata is a species of woody evergreen flowering trees and shrubs, part of family Winteraceae. The species is endemic to New Zealand. All Winteraceae are magnoliids, associated with the humid Antarctic flora of the southern hemisphere.
Description
Pseudowintera colorata, or mountain horopito, is an evergreen shrub or small tree (1–2.5 m) commonly called pepperwood because its leaves have a hot taste. It is also known as the New Zealand pepper tree, winter's bark, or red horopito. It is so named because early taxonomists recognized the similarity between horopito and the South American Drimys winteri that provided the herbal remedy "winter's bark." They are both members of the Winteraceae family, which are mainly found on the land masses that once made up the great southern continent of Gondwana - South America, Australia, New Zealand and New Guinea. Its yellowish-green leaves are blotched with red, with new leaves in the spring being bright red. It is distributed within lowland forests up to higher montane forests from 36° 30' South as far southward as Stewart Island/Rakiura. A characteristic plant association for P. colorata is within the podocarp forests of Westland, where alliant understory plants such as Rumohra adiantiformis, Ascarina lucida, Pseudopanax colensoi, Pseudopanax edgerleyi and Blechnum discolor are found.
The evergreen horopito plant is continually exposed to attack by various insects and parasites and its occurrence in high rainfall areas makes it particularly susceptible to attack by fungi.
Uses
- Pseudowintera colorata is grown as a spice, as an ornamental, and as a traditional medicine plant.
- Horopito is documented in the treatment of skin diseases such as ringworm, or for venereal diseases.
- The bruised leaves are used as a poultice for chaffing of the skin, or to heal wounds, bruises or cuts".[1]
- Early European settlers to New Zealand also used horopito for medicinal purposes. For internal use, leaves were either chewed or prepared as a tea. "The leaves and bark are aromatic and pungent; the former are occasionally used by settlers suffering from diarrhoeic complaints."[2]
- A decoction of the leaves was taken for stomach ache and was known as "Maori Painkiller" and "Bushman's Painkiller."[3]
