There are no uses in modern medicine, although it was widely used in medicine before World War II. In the Indian (Ayush) system of medicine, "hudar" is a mixture containing Strychnos nux-vomica and used to elevate blood pressure.
The strychnine tree (Strychnos nux-vomica L.) also known as nux vomica, poison nut, semen strychnos and quaker buttons, is adeciduous tree native to India, and southeast Asia. It is a medium-sized tree in the family Loganiaceae that grows in open habitats. Its leaves are ovate and 2–3.5 inches (5.1–8.9 cm) in size.
It is a major source of the highly poisonous, intensely bitter alkaloids strychnine and brucine, derived from the seeds inside the tree's round, green to orange fruit. The seeds contain approximately 1.5% strychnine, and the dried blossoms contain 1.0%. However, the tree's bark also contains brucine and other poisonous compounds.
The use of strychnine is highly regulated in many countries, and is mostly used in baits to kill feral mammals, including wild dogs, foxes, and rodents. Most accidental poisoning is by breathing in the powder or by absorption through the skin.
