||Mostly grown as an ornamental plant. Manuka is a nursery tree and often forms large areas that protect regenerating forest seedlings and form a shelter for native orchids and other small plants. Manuka wood is red coloured, hard and durable. It has been used for fencing, for tool handles and as a firewood. Manuka was used traditionally by Māori for a variety of ailments from urinary complaints, head colds, sedation to skin disorders. Infusions and poultices were made from the leaves and inner bark and the seed capsules and sap were chewed. Early european migrants produced a tea from Manuka leaves (hence it's name). Today's modern uses are focused on topical applications for skin, cosmetic, fungal conditions and topical anti-histamine use. However, the variability in Manuka essential oils suggests caution in their usage, as does the fact that the oils have not been tested for toxicity. Manuka honey can be eaten, used in cooking or used externally.
||Manuka essential oils include sesquiterpene hydrocarbons (> 60%), oxygenated sesquiterpenes/triketones (approx 30%), and monoterpenes (< 3%). Individual components include: monoterpene hydrocarbons, a-cubebene, b-pinene, r-cymene, g-terpinene, a-copaene, b-caryophyllene, aromadendrene, calamanene, limonene, myrcene, 8-cineole, linalool esters, copaene, elemene, gurjunene/aromadendrene, farnesene/ caryophyllene, selinene, and cadinene skeletons.
