cashew tree

Anacardium occidentale

Read before use: the information below describes traditional and informational uses — it does not replace advice from a healthcare professional. If in doubt, during pregnancy or breastfeeding, ongoing treatment, or use in children, seek advice before use.

Enhanced precautions for this plant: The cashew nut shell contains a caustic liquid (cardol balm) that is highly irritating and allergenic; it must never be handled or consumed raw. People with tree nut allergies should avoid any internal or external use of the cashew tree. Prolonged internal use of the bark or leaves should remain occasional and be discussed with a healthcare professional, particularly when medications are being taken. Not recommended during pregnancy, breastfeeding, or in young children, due to insufficient data on the safety of traditional preparations.

Decoction — Bark

Cashew tree bark decoction

Boil a few pieces of dried bark in water for about fifteen minutes, then let cool before straining. Traditionally used for occasional internal use or as a gargle, this preparation is best supervised by a professionally trained herbalist. Dosage should be validated with a healthcare professional or recognized pharmacopoeia before use.

Infusion — Leaves

Dried leaf infusion

Pour simmering water over dried leaves and steep for about ten minutes before straining. This infusion was traditionally consumed in small quantities, accompanying seasonal colds. Dosage should be validated with a healthcare professional or recognized pharmacopoeia before use.

Compress

Soothing skin compress

Soak a clean cloth in cooled decoction of leaves or bark and apply to the affected area. This external use is limited to minor skin irritations and is not suitable for open or infected wounds. Dosage should be validated with a healthcare professional or recognized pharmacopoeia before use.

Where to find it

Obtaining the plant

The cashew tree grows wild and cultivated in tropical regions of South America, particularly in Brazil; its dried leaves and bark are sometimes found in specialized herbal shops, while the processed cashew nut is widely available commercially.
