Overview & Habitat

Calotropis gigantea, also known as the Giant Milkweed or Crown Flower, stands at the crossroads of traditional medicine and deadly toxicity.
Revered in Ayurvedic medicine for its potential healing properties.
The plant houses dangerous toxins that can cause harm if mishandled.
C. gigantea demands both respect and caution.
Its striking white or purple flowers are used in garlands and royal symbols.
Beneath its beauty lies a plant that science is still trying to fully understand.

Calotropis gigantea is a perennial shrub that thrives in the arid and semi-arid regions of Asia and Africa.
It can grow up to 4 m tall.
The plant is easily recognized by its large, broad leaves covered in a layer of soft, white, woolly hairs, giving them a silvery appearance.
The stout, woody stems contain a milky latex that flows freely when cut.
The latex is both revered for its medicinal qualities and feared for its toxicity.
This latex has been used in traditional medicine for centuries but is a potent irritant, causing severe inflammation on contact with skin or eyes.

The flowers of Calotropis gigantea are star-shaped, often pale lavender or white, and grow in clusters at the tips of the branches.
Despite their beauty, the flowers serve a more sinister purpose in the plant’s survival strategy by attracting pollinators like bees and butterflies.
The nectar of the flowers attracts pollinators, but the latex can be deadly if ingested.
The flowers play a cultural role in Hindu rituals, where they are offered to deities, often as garlands, and symbolize purity and divinity.

The fruit of C. gigantea takes the form of large, inflated pods containing numerous seeds with silky white hairs that aid in wind dispersal.
These pods are another repository of the plant’s toxic arsenal.
The seeds are coated with a thin layer of latex, ensuring the plant remains dangerous even in its reproductive phase.

Calotropis gigantea belongs to the Apocynaceae family, known for toxic latex and alkaloids.
The genus Calotropis is studied extensively for its dual nature—useful yet harmful.
The species gigantea is named for its large size compared to Calotropis procera.
Its taxonomic classification places it squarely within a family that has fascinated scientists for its medicinal properties while reminding them of its lethal capabilities.

In Ayurvedic medicine, Calotropis gigantea is considered a pharmacopeia, providing life-saving remedies in the hands of traditional healers.
Its latex has been used to treat a range of conditions, from digestive disorders to skin diseases, and even as a treatment for leprosy.
The roots and bark are applied to snakebites, while the leaves are used in poultices to reduce inflammation.
The same compounds that give the plant its medicinal properties are also highly toxic, with cardiac glycosides causing vomiting, diarrhea, and, in extreme cases, death from cardiac arrest if ingested in the wrong dosage.
The plant’s fibers are used as a substitute for cotton, and its latex is being explored as a potential source for biofuel.
Calotropis gigantea offers significant benefits across various fields when handled carefully.
