The lanceolate, small leaves with the silver hairs can be prepared as tea, which on the one hand is said to be more delicious than the classic tea (C. sinensis), but on the other hand is particularly appreciated for its health effects. Manuka or New Zealand teatree is both a medicinal and a stimulant plant that has long been used by Maori. It contains manuka oil, which is said to have an anti-inflammatory and antibacterial effect. Manuka honey is also marketed as a medicine.
Those who brew the leaves for indulgence should allow them to brew longer than black tea, as the acerbic aroma is only slowly released into the water.
