African dream herb (Entada rheedei)

Entada rheedei is a giant forest liana that produces one of the longest pods of any plant — up to a metre or more — holding large, flat, polished brown seeds. Those seeds float, travel on ocean currents and wash up on distant beaches as sea beans. In parts of Africa the seed is called the dream herb. The seeds are toxic raw, and they are best kept as curiosities.

How to recognise African dream herb

It is a woody climber that can reach the tops of tall trees, with twice-pinnate leaves that end in a tendril.

Tiny cream flowers grow in long, narrow spikes. The fruit is a huge, flat, woody pod, constricted between the seeds, which breaks into one-seeded segments.

Each seed is a hard, glossy, chestnut-brown disc about five centimetres across. Air spaces inside let it float for months.

Elephant creeper, Argyreia nervosa, is an unrelated morning-glory vine with silver-backed heart-shaped leaves.

Modern notes on African dream herb

The seeds contain saponins and other compounds that are toxic if eaten raw. Pharmacological studies remain largely at the laboratory stage.

Botanists and beachcombers study it as a drift seed. Entada seeds have crossed oceans and turned up on beaches far from any parent plant.

African dream herb safety

Do not eat the seeds. Keep them away from children, who may treat them as sweets or toys to chew.

Ecology and sourcing

It grows in evergreen and semi-evergreen forest in the Western Ghats, north-east India and the Andamans, and across tropical Africa and Asia.

Seeds dropped into rivers can reach the sea, which explains its wide spread along tropical coasts.
