Borgia plant

The Borgia plant is a poisonous plant native to planet M-113. The plant contains an alkaloid poison which is similar to the nightshade variety of plants that were native to Earth, and had a chemical structure similar to plants from many class M planets.

In 2266, the M-113 creature, posing as Nancy Crater, blamed the death on USS Enterprise crewman, Scott Darnell, on him having eaten a piece of Borgia plant. However, this statement was later proven to be false by Commander Spock and Dr. Leonard H. McCoy. (TOS episode: "The Man Trap").
