Final answer:
The anticholinergic plant with a forked root mentioned in the Bible is the mandrake. Mandrake contains the anticholinergic compound hyoscine, which has been used for its sedative effects. Other plants with anticholinergic properties include belladonna and henbane, both of which are potentially fatal when ingested.
Step-by-step explanation:
The anticholinergic plant with a forked root that is mentioned in the Bible is the mandrake (C). Mandrake contains hyoscine, also known as scopolamine, which is an anticholinergic compound. This plant has a long history of being used for its sedative properties, and its forked root, which can resemble the human form, has led to many superstitions and myths. In terms of toxicity, other plants like belladonna or deadly nightshade and henbane are also known for their anticholinergic properties. Belladonna contains compounds like atropine and scopolamine, and it was historically used cosmetically to dilate pupils but can be fatal when ingested. Meanwhile, henbane is toxic to various animals and can induce hallucinations and other anticholinergic symptoms in humans.
