What are the pharmacological activities of Vitex negundo?

This plant has anti-inflammatory, antioxidant, antibacterial, antiviral, and analgesic pharmacological activities. Its bioactive compounds work to neutralize free radicals, which provides significant protection against oxidative stress in biological systems. The plant also exhibits potent antimicrobial properties that help inhibit the growth of various pathogenic bacteria and viruses. Furthermore, its ability to reduce inflammation and alleviate pain makes it a valuable subject for treating musculoskeletal and respiratory conditions. These diverse therapeutic effects stem from a complex profile of phytochemicals present in its leaves and stems.

According to a study published by "Frontiers in immunology", a new acid isolated from Vitex negundo L. herb has been characterized. This novel Vitenegu acid specifically inhibits NLRP3 inflammasome activation. The substance works by blocking the oligomerization of NLRP3, which inhibits NLRP3 inflammasome assembly and activation. Importantly, this inhibition occurs without affecting NLRC4 or AIM2 inflammasomes. In vivo data demonstrate that Vitenegu acid exerts therapeutic effects on NLRP3 inflammasome-dependent inflammation. These results suggest that Vitenegu acid is a candidate therapeutic agent for treating NLRP3 inflammasome related diseases.

What medicinal compounds this plant contains?

This plant contains a diverse array of bioactive medicinal compounds including the flavone vitexin, the iridoid glycosides negundoside and nishindaside, the series of vitnegundiins A through G, and the alkaloid vitedoaamine A. These specific phytochemicals contribute to the plant's documented pharmacological activities such as anti-inflammatory and antioxidant effects. The presence of these various chemical classes allows the species to interact with multiple biological pathways. Researchers continue to study how these unique molecules function both individually and in combination.

According to a study published by "Journal of pharmaceuctical and biomedical analysis", a total of 31 compounds were identified in Vitex negundo L. var. cannabifolia, consisting of 10 phenolic acids, 19 flavonoids, and 2 iridois. Eleven compounds, including caffeic acid, neochlorogenic acid, cryptochlorogenic acid, isochlorogenic acid B, isochlorogenic acid A, isochlorogenic acid C, schaftoside, isoschaftoside, flavosativaside, vitexin 2"-rhamnoside, and kaempferol 3-(6"-malonylglucoside), were detected for the first time in this plant. Quantitative analysis focused on 17 phenolic compounds, with all analytes being detected within 8 min. The limits of detection and quantification were less than 7.251 and 26.454 ng/mL, respectively. Precision and stability values showed relative standard deviations of less than 2.87%, 3.87%, 4.86%, 4.70%, and 3.61%. For quality control, chlorogenic acid, agnuside, isochlorogenic acid A, and isochlorogenic acid C might be selected as quantitative markers.

According to a study published by "Journal of Alzheimer's disease : JAD", the medicinal plant Vitex negundo contains the flavonoid vitegnoside, which is used as a folk medicine in several Asian countries including China. This plant component was investigated for its potential therapeutic effect against the progression of Alzheimer's disease (AD), a chronic neurodegenerative disorder. In an in vitro AD cell model using the human neuroblastoma SH-SY5Y cell line, vitegnoside demonstrated neuroprotection by improving cell viability and maintaining cytomembrane integrity. While it failed to decrease AβPP expression or Aβ40/42 levels, it protected mitochondrial function and restored the imbalance between pro-apoptotic and anti-apoptotic proteins. Additionally, vitegnoside inactivated p38 MAPK/MK2, JNK/c-Jun, and downstream NF-κB inflammatory transductions to combat copper-induced Aβ neurotoxicity.

What side effects this plant can have?

This plant can cause significant adverse health effects including the disruption of the latter stages of spermatoogenesis, reduced androgen production, asthma, migraine, and eye pain. Exposure to its compounds may interfere with male reproductive health by altering hormonal balances and sperm development. Some individuals might experience respiratory complications such as asthma after contact or ingestion. Neurological and sensory issues can also occur, specifically manifesting as intense migraine headaches or localized eye pain. These diverse side effects highlight the potential toxicity and physiological impact of the species.

According to a study published by "Journal of ethnopharmacology", a flavonoid-rich fraction of Vitex negundo seeds consisting of 5,7,3'-trihydroxy, 6,8,4'-trimethoxy flavones was administered at 10 mg/kg i.p. every other day. Treatment lasted for 30 days in castrates and 60 days in intact dogs, causing a disruption of the latter stages of spermatogenesis and leaving epididymides devoid of spermatozoa. This fraction caused significant reductions in protein, sialic acid, and RNA contents of the testes and epididymides, while testicular cholesterol and phosphatase activity were elevated. Low levels of sialic acid in the testes and epididymides reflected reduced androgen production. In dogs that underwent castration followed by treatment with the fraction, a reduction in the cellular heights of the epididymides occurred.

The main side effects this plant can have are shown in the list below.

  • disruption of the latter stages of spermatoogenesis
  • reduced androgen production
