⚠️ Important Warning: The milky latex of Erukku is highly toxic and can cause severe irritation, burning, and blindness upon contact with eyes. Ingestion can be fatal. Always handle with extreme caution and never self-medicate. Siddha preparations strictly follow purification processes (Suththi) to mitigate toxicity.

👁️ Appearance

Leaves: Large, ovate-oblong leaves, pale green, thick, velvety, with a whitish-downy underside. They exude milky latex when broken.

Stem: Stout, erect stem with grayish-white bark, woody at the base, and covered in fine hairs. It branches freely and contains abundant milky latex.

Fruit/Flower: Inflated, fleshy, green fruit resembling a small mango or apple, containing numerous flat, brown seeds with silky white tufts (pappus) for wind dispersal.

🌱 Where Erukku grows

Erukku is highly adaptable and thrives in various harsh conditions, making it a common sight in many regions.

• India (especially arid and semi-arid regions)
• Southeast Asia
• Parts of Africa
• Southern China

⚠️ Do not confuse with

While 'Erukku' generally refers to *Calotropis gigantea*, its close relative, *Calotropis procera* (Sodom's Apple), shares similar characteristics and uses. *C. procera* typically has greenish-yellow flowers and is more robust. Both are toxic and require similar precautions.
