The Manuka plant (Leptospermum scoparlum) was known to have special medicinal and therapeutic properties.
The Māori people used the leaves and bark for a wide range of ailments, including urinary problems and as a febrifuge (to reduce fever). The leaves were boiled and the hot vapour inhaled for head colds. Leaves and bark were boiled together and the warm liquid rubbed on stiff backs and rheumatic joints. It was also used as a diuretic, a sedative, a painkiller, for inflammation of the breasts, and for healing fractures. Boiled bark was used to relive constipation., as a gargle, and for bathing sore eyes.
Fresh sap was taken as a purifier, seed capsules were boiled and the fluid used externally for bruises and inflammation, and internally for diarrhoea, and dysentery.
