Hedycarya arborea

Please read before use: the information below describes traditional and informational uses — it does not replace the advice of a healthcare professional. In case of doubt, pregnancy, breastfeeding, ongoing treatment, or use in children, seek advice before use.

Enhanced precautions for this plant: Western documentation on this plant remains scarce and fragmentary; any use must be undertaken with the utmost caution. Do not self-administer preparations based on this plant without the advice of a healthcare professional or a qualified traditional practitioner. Avoid all use during pregnancy or breastfeeding, and in children, due to insufficient safety data. In case of doubt regarding botanical identification, refrain from use: several New Zealand forest species may be confused with one another.

Compress — Leaves

Fresh leaves in topical application

The leaves were crushed or slightly heated then applied directly to the affected area, according to reported traditional practices. Consultation with a professional is recommended before any use. Dosage must be validated with a healthcare professional or a recognized pharmacopoeia before use.

Infusion — Leaves

Traditional leaf infusion

A few leaves were sometimes infused in hot water according to poorly documented traditional uses. In the absence of reliable data on quantities and safety, this preparation should only be considered under the guidance of a professional familiar with the plant. Dosage must be validated with a healthcare professional or a recognized pharmacopoeia before use.
