Castor

A Plant of Ancient Power

The castor plant (Ricinus communis) is one of the most fascinating and paradoxical plants in human history. Native to Northeast Africa and the Middle East, it has been cultivated for thousands of years for its medicinal, industrial, and ornamental value. Its large, star-shaped leaves, spiked seed pods, and resilience make it both striking and useful. However, its beauty hides a deadly secret: while the oil derived from its seeds is a valuable therapeutic remedy, the raw seeds contain ricin, one of the most potent poisons known to humans.
