composting Castor bean
 

Can Castor bean plants be composted? Is the entire plant poisonous? Is it okay if the compost is not used for plants that will be eaten?

My understanding is that the entire plant is highly toxic.

Pathophysiology

These beans contain potent toxalbumins that inhibit protein synthesis and cause severe cytotoxic effects on multiple organ systems. Castor beans contain the toxalbumin ricin, and jequirity beans contain abrin. The toxins are present in all parts of the plant but are most concentrated in the beans or seeds. Symptoms include delayed gastroenteritis, which may be severe and hemorrhagic, followed by delirium, seizures, coma, and death. The beans are covered by a hard, relatively impervious outer shell that must be chewed or broken in some way in order for the toxalbumin to be released and, thus, present a toxic hazard. Castor beans are particularly antigenic and may cause severe cutaneous hypersensitivity and systemic reaction. (emphasis added)

Still poisonous after composting, though?

Thanks. That link doesn't work, but I think that was my thread. I posted it there too to get some different opinions.

I know the plant is toxic. But I let the leafs fall and rake them over to my compost piles. The steams are like trunks and all hard wood so I throw they over the fence and grind it down to smaller parts ever other year. The seeds I try to throw over the fence and keep a few each year.
