Ik kon het niet laten om die indrukwekkende, bijzondere en giftige zaden van de Wonderboom nog maar eens te fotograferen.

The name Ricinus is derived from the Latin word for insect because the seeds resemble beetles in shape and markings. Castor beans are used as art objects and ornaments. The Egyptians used castor oil as a lamp oil and an unguent, also ingesting the oil with beer as a purgative. The roots, leaves, and seeds have a place in traditional folk remedies throughout the world. Other recorded medicinal uses include induction of labor, as a cathartic, as a contraceptive cream, and as a skin emollient. The fast-drying, nonyellowing oil has been used in the manufacture of high-grade lubricants for industrial machinery and aircraft engines and in dyes, inks, paint, and varnishes. The castor cake or pulpy residue that remains after oil extraction has been used as animal feed and as fertilizer despite its unsuitability due to traces of toxins.
Ricin was developed as a biological warfare agent in the 1920s and was considered for use during World Wars I and II. Arrests for terrorism activity have been made since the 1990s for the possession of ricin or castor beans.
