had the following information: Perhaps just one milligramof ricin can kill an adult. The symptoms of human poisoning begin within a few hours of ingestion. The symptoms are:
* abdominal pain * vomiting * diarrhea, sometimes bloody. Within several days there is:
* severe dehydration, * a decrease in urine, * and a decrease in blood pressure. If death has not occurred in 3-5 days, the victim usually recovers.
The scientific name for a castor bean is Ricinus communis.

Castor beans are typically a deterrent for mice because of their toxicity. If a mouse were to eat them, they will be poisoned.
While the answer is debatable, the castor plant is high on the list. One castor bean can kill a person. The toxin ricin is derived from castor beans.
The active poison in the castor bean is ricin, a deadly water-soluble protein called a lectin.
the deadilest plant would be "castor bean plant"
Deadliest plant on earth...Well that's alot of plants. My best guess would be the castor bean plant it produces castor beans which are used to make castor oil. However the beans have another ingredient, ricin which is very deadly and has been used in assasinations. It may only take one castor bean to kill an adult. Then again there are alot of plants on earth and there may be some competition with the castor plant. Water Hemlock might give the castor bean some competition. bacause GOD made them!
Castor bean is not poison to deer unless the group of deer of your reagion has alergy to it , it is common cows or goats invade castor plantation and just be all right that happen because the toxin is iion the seed and the deer is going to eat the leaves
