🌴 Cycas

Cycas media · Cycadaceae

🦘 Australia
🧠 To remember it“Cycas: days of soaking before a bite, never less” - the most demanding preparation in the entire Australian bush, and the most dangerous to shortcut.
Cycas — Cycas media

🔍 Identify it without mistakes

Woody plant resembling a small palm tree, with a thick, scaly single trunk topped by a crown of large, thick, leathery, dark green pinnate leaves. Produces orange seed cones in the leaf axils (cycads are gymnosperms, related to conifers, no real flowers).

  1. palm-like scaly trunk but very rigid and spiky leaves
  2. rapid regrowth of foliage after a bushfire
  3. orange seeds grouped in loose cones
Size2-8 m
Floweringno real flowers (gymnosperm), cone production
Habitatseasonally dry tropical sclerophyll forests, near the east coast of Queensland, scattered populations in the northern Northern Territory and Western Australia

⚠️ Not to be confused with

Sago palm (true sago palms, e.g. Metroxylon sagu, or ornamental Cycas revoluta improperly called "sago palm") (Metroxylon sagu)none for the true sago palm — but the reverse confusion is the real threat: because cycas is also called "sago palm", believing that its pith or seeds are prepared like those of a true palm tree, without the prolonged soaking in running water that eliminates cycasin, is potentially deadly

To tell them apart: a true palm tree (Metroxylon) has a tall, smooth, ringed single trunk topped by a crown of large fronds, and never produces a cone; cycas has a shorter, scaly trunk and produces a cone or a mass of orange seeds directly in the leaf axils — the presence of a cone definitely signals a cycad, never a palm tree

🍽️ Eating it

Partsseeds, only after thorough preparation
Seasonseasonal fruiting depending on rainfall
Tasteneutral flour once completely processed and cooked

Preparation : MANDATORY and lengthy: remove the outer husk, dry the kernels, then soak them for several days in running water (continuously renewed) to eliminate water-soluble neurotoxins, then crush into a fine paste and cook under ashes. Without this prolonged soaking in running water, all parts of the plant are highly toxic

💊 Healing with it

aucun

Level of evidence : traditional use — Wikipedia - Cycas media

⚠️ all parts of the plant are toxic in the raw state (notably cycasin and BMAA), responsible for acute poisoning (vomiting, liver damage) and suspected chronic neuropathies after repeated exposure to poorly prepared seeds; never consume without the complete protocol of soaking in running water for several days followed by cooking
