What medicinal compounds this plant contains?
This plant contains the potent alkaloids strychnine, brucine, brucine N-oxide, strychnine N-oxide, and 4-hydroxystrychnine. These chemical constituents are primarily responsible for the plant's extreme toxicity to humans and animals. Strychnine and brucine act as powerful central nervous system stimulants by antagonizing glycine receptors. The N-oxide derivatives represent oxidized variations of these primary alkaloids found within the seed matter. Research into these specific compounds often focuses on their physiological effects and potential pharmacological applications despite their inherent danger.
According to a study published by "Cancer letters", Strychnos nux-vomica contains the indole alkaloid brucine. This compound attenuates VEGF-induced angiogenesis by inhibiting the VEGFR2 signaling pathway both in vitro and in vivo. Brucine inhibits VEGF-induced cell proliferation, chemotactic motility, and capillary-like structure formation in HUVECs in a dose-dependent manner. It suppresses p-VEGFR2 kinase activity and inhibits downstream protein kinases including Src, FAK, ERK, AKT and mTOR. Furthermore, brucine downregulates levels of VEGF, NO, IL-6, IL-8, TNF-α and IFN-γ in HUVECs.
The primary medicinal compounds of this plant are shown in the list below.
- Brucine
- Strychnine
- brucine N-oxide
- strychnine N-oxide
- strychine
What health conditions is this plant used for?
This plant is used for treating epilepsy, neurological disorders, and various behavioral disorders by modulating specific nervous system effects. Its active alkaloids interact directly with the central nervous system to influence how neurons communicate. These potent chemical compounds are often studied for their ability to impact complex neurodisorders through their stimulation of receptor sites. By altering chemical signaling, the plant's derivatives aim to stabilize irregular electrical activity in the brain. Consequently, researchers examine its potential to manage both physical seizures and psychological symptoms.
According to a study published by "Journal of ethnopharmacology", processed Nux vomica seed extracts and homeopathic medicinal preparations are used in traditional Indian and Chinese medicine for respiratory, digestive, neurological and behavioral disorders. These homeopathic medicinal preparations, including 6CH, 12CH and 30CH potency, show anticonvulsant and antiepileptogenic potential in acute and chronic models of epilepsy. In mice models, subconvulsive doses of 35 mg/kg induced kindling over 29 days to test effects on cognition, memory and motor impairment. The preparations were tested against acute seizures induced by 70 mg/kg of PTZ to evaluate the duration of Generalized tonic-clonic seizures. The study found that these preparations attenuated behavioral impairment and reduced oxidative stress by affecting MDA, GSH and SOD levels.
The main health conditions this plant is used for are shown in the list below.

What are the herbal preparations of this plant?
This plant is Strychnos nux-vomica, a source of potent alkaloids used to create medicinal preparations such as Semen Strychni, alcoholic dilutions, aqueous extracts, mother tinctures, and powders. These preparations are derived from the seeds of the plant and must be handled with extreme care due to their high toxicity. Practitioners may utilize a mother tincture as a concentrated base for further medicinal processing. Aqueous extracts are prepared by leaching the active components through water, while powders offer a more direct form of the substance. Alcoholic dilutions serve to reduce the intensity of the alkaloids to safer, therapeutic levels for specific clinical applications.
According to a study published by "Yakugaku zasshi : Journal of the Pharmaceuticaal Society of Japan", a method was developed to determine strychnine and brucine, the most abundant alkaloids in processed Semen Strychni. The limits of quantification for different tissue or plasma samples were in the range of 0.039-0.050 µg/ml. Extraction recoveries varied from 71.63 to 98.79% with a linear range of 0.05-2 µg/ml and a correlation coefficient of over 0.991. Intra- and inter-day precision for these measurements was less than 15%. After the intravenous administration of 1 mg/kg crude alkaloids fraction extracted from processed Semen Strychni, strychnine and brucine showed similar tissue distribution. The highest levels were observed in the kidney, while the lowest level was found in the brain.

What side effects this plant can have?
This plant can cause severe systemic damage including neurotoxicity, hepatotoxicity, nephrotoxicity, cytotoxicity, and metabolic disturbance. The alkaloids within the seeds target the central nervous system, leading to intense muscle spasms and potential neurological failure. Consumption also triggers cellular destruction through cytotoxicity, which can compromise vital organ functions. These toxins can lead to significant hepatotoxicity and nephrotoxicity by damaging the liver and kidneys respectively. Finally, the chemical impact often results in profound metabolic disturbance that disrupts the body's chemical balance.
According to a study published by "Nutrients", Strychnos nux-vomica, specifically in the form of Semen Strychni, is known for its fatal neurotoxicity caused by strychno alkaloids. These alkaloids include two main components, strychnine and brucine, which are rapidly absorbed into the brain. These substances peaked early at 0.5 h and were mainly located in the hippocampus and cerebellum. The presence of these alkaloids induces neurotoxicity and oxidative stress in subjects.
The main side effects this plant can have are shown in the list below.
- neurotoxicity
- hepatotoxicity
- nephrotoxicity

- metabolic disturbance
What herbs are paired with Strychnos nux-vomica?
This plant is traditionally paired with herbs such as ginger, cinnamon, and black pepper to mitigate the severe gastrointestinal distress caused by its potent alkaloids.
Practitioners often combine these warming spices to balance the intense physiological effects of the strychnine content during controlled administration. Some traditional formulations also include calming botanicals like chamomile to soothe the central nervous system. These specific combinations are designed to manage the toxicity while attempting to leverage the plant's stimulating properties.
Careful measurement of these pairings is essential due to the extreme danger of accidental overdose.
