Dacrydium cupressinum

Dacrydium cupressinum
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: Traditional use is poorly documented by modern scientific research: caution is advised, particularly for prolonged application or internal use. Certain parts of the plant (seeds, resin) may present toxicity if consumed in large quantities; do not act as a practitioner without the advice of a qualified professional. Avoid any use during pregnancy or breastfeeding, as well as in young children, due to insufficient data. Do not confuse with other similar-looking conifers; reliable botanical identification is essential before any harvesting.
Decoction — Root

Traditional root decoction

The roots were cut into small pieces then boiled at length in water, according to reported but poorly formalized practices. This preparation requires professional advice before any use, as traditional dosages are not reliably documented. Dosage must be validated with a healthcare professional or recognized pharmacopoeia before use.

Poultice — Leaves

Fresh leaf poultice

Fresh leaves were crushed then applied directly to the affected skin area, in traditional external use. A healthcare professional should be consulted before any application, particularly on damaged skin. Dosage must be validated with a healthcare professional or recognized pharmacopoeia before use.

Powder — Seeds / fruits

Preparation of dried fruits

The fleshy fruits were sometimes dried then reduced to a coarse powder before occasional consumption. This ancient food use remains poorly documented and should only be reproduced with caution and informed advice. Dosage must be validated with a healthcare professional or recognized pharmacopoeia before use.
