Harvest Tips
For medicinal use, harvest leaves year-round but ideally during flowering season for peak potency. Pick young, tender leaves in the morning after dew dries.

- 🌱 The plant was used by Maori people and early European settlers in New Zealand as a medicinal tea long before modern scientific validation of its benefits.
- 🌱 Despite being called 'tea tree,' it is not related to the common tea plant (Camellia sinensis); the name reflects its traditional use in steeping for beverages.
