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: Neem seed oil is known to be toxic when taken orally, especially in young children: internal use should be avoided without supervision by a healthcare professional. Not recommended during pregnancy and breastfeeding due to its traditionally reported emmenagogue properties. Medical advice or consultation with a qualified herbalist is recommended before any internal use, particularly if taking medication. Reserved for external use in home preparations; avoid prolonged contact with mucous membranes without appropriate dilution.

Infusion for skin wash — Leaves

Traditional Neem leaf wash

Infuse a handful of dried leaves in hot water for about ten minutes, allow to cool, then use as a local skin wash. This preparation was traditionally reserved for external use only. Dosage should be validated with a healthcare professional or recognized pharmacopoeia before use.

Dried leaf powder — Leaves

Dried leaves in protective sachets

Leaves are shade-dried then stored whole or lightly crushed, placed in fabric sachets within cupboards or grain stores. This domestic practice does not require ingestion. Dosage should be validated with a healthcare professional or recognized pharmacopoeia before use.

Infused oil (external use) — Seeds / fruits

Seed oil for external application

Oil extracted from seeds was traditionally applied in very small amounts to the skin or scalp, always diluted. A professional should be consulted before any use, as this oil is known to be toxic if ingested. Dosage should be validated with a healthcare professional or recognized pharmacopoeia before use.
