    Indian Journal of Natural Products and Resources Vol. 2(3), September 2011, pp. 286-291 Medicinal uses and biological activities of Argyreia speciosa Sweet (Hawaiian Baby Woodrose) An Overview Ancy Joseph*, Samuel Mathew, Baby P Skaria and E C Sheeja Aromatic and Medicinal Plants Research Station (Kerala Agricultural University), Odakkali, Asamannoor Post-683 549 Ernakulam District, Kerala, India Received 2 June 2010; Accepted 16 November 2010 Argyreia speciosa Sweet (Family Convolvulaceae) is an important ‘rasayana’ herb used extensively as an adaptogen in the Ayurvedic system of medicine. It is commonly known as Hawaiian Baby Woodrose, Elephant creeper or Woolly morning glow in English and in Sanskrit, it is called as Vridhadaraka meaning ‘anti-aging’. It is a large climber growing throughout India. It has been assigned various medicinal properties by Ayurvedic Materia Medica. The root is regarded as an alternative tonic and used in cases of rheumatism and neurological disorders. A wide range of phytochemicals has been isolated from the plant and possesses various traditional and tribal uses for cure of human ailments. Pharmacological activities such as anti-oxidant, anti-inflammatory, anti-rheumatic, immunomodulatory, adaptogenic and hepatoprotective have also been reported. Adverse side effects have made the use of many modern medicines limited and it is worthwhile to explore the possibility of this drug for the treatment of liver, rhueumatic and neurological complaints. This article reviews studies on medicinal uses on this important herb.

    Hallucinogens And Dissociative Drug Use And Addiction Introduction Hallucinogens are a diverse group of drugs that cause alterations in perception, thought, or mood. This heterogeneous group has compounds with different chemical structures, different mechanisms of action, and different adverse effects. Despite their description, most hallucinogens do not consistently cause hallucinations. The drugs are more likely to cause changes in mood or in thought than actual hallucinations. Hallucinogenic substances that form naturally have been used worldwide for millennia to induce altered states for religious or spiritual purposes. While these practices still exist, the more common use of hallucinogens today involves the recreational use of synthetic hallucinogens. Hallucinogen And Dissociative Drug Toxicity Hallucinogens comprise a collection of compounds that are used to induce hallucinations or alterations of consciousness. Hallucinogens are drugs that cause alteration of visual, auditory, or tactile perceptions; they are also referred to as a class of drugs that cause alteration of thought and emotion. Hallucinogens disrupt a person’s ability to think and communicate effectively. Hallucinations are defined as false sensations that have no basis in reality: The sensory experience is not actually there. The term “hallucinogen” is slightly misleading because hallucinogens do not consistently cause hallucinations. 1 ce4less.com ce4less.com ce4less.com ce4less.com ce4less.com ce4less.com ce4less.com How hallucinogens cause alterations in a person’s sensory experience is not entirely understood. Hallucinogens work, at least in part, by disrupting communication between neurotransmitter systems throughout the body including those that regulate sleep, hunger, sexual behavior and muscle control. Patients under the influence of hallucinogens may show a wide range of unusual and often sudden, volatile behaviors with the potential to rapidly fluctuate from a relaxed, euphoric state to one of extreme agitation and aggression.

Box1 | 3720 BA Bilthoven The Netherlands www.rivm.nl/en Page 2 of 42 RIVM letter report 2019-0210 Synopsis Risk assessment of Argyreia nervosa In the Netherlands, seeds from the plant Hawaiian Baby Woodrose (Argyreia nervosa) are being sold as a so-called ‘legal high’ in smart shops and by internet retailers. The use of these seeds is unsafe. They can cause hallucinogenic effects, nausea, vomiting, elevated heart rate, elevated blood pressure, (severe) fatigue and lethargy. These health effects can occur even when the seeds are consumed at the recommended dose. This is the conclusion of a risk assessment performed by RIVM. Hawaiian Baby Woodrose seeds are sold as raw seeds or in capsules. The raw seeds can be eaten as such, or after being crushed and dissolved in liquid (generally hot water).

  • From Argyreia Nervosa T
    Recreational Use of Ergoline Alkaloids from Argyreia Nervosa t WILLIAM E. SHAWCROSS* This article is a review of the botany and chemistry of Argyreia nervosa (a relative of the common morning glory), and of the recreational use of ergoline alkaloids found in its seeds. In addition to the scientific literature dealing with this recently discovered hallucinogen, the popular literature of the drug culture has been exhaus­ tively searched for reports of its use. This information has been supplemented by self-experimentation and by reports from a panel of volunteers. This author's interest in Argyreia nervosa seeds had been stirred some time ago on seeing them for sale in a head shop. Preliminary investigation revealed that the entire literature on the hallucinogenic use of these seeds was limited to some hundred papers and references- a manageable number. And, fortunately, the seeds were inexpensive and legal to possess. BOTANY OF ARGYRF.IA NERVOSA (BURM . F.) BOJER A charming look at "Argyreia nervosa. Elephant Creeper.

Methods: Stem and leaves of the selected 23 taxa were collected and shade dried. The methanol extract was used for preliminary screening of phytochemicals such as alkaloids, carbohydrates, glycosides, saponins, proteins, phytosterols, terpenoids, fixed oils, phenolic compounds, flavonoids and tannins. Results: Phytochemicals were present in all selected taxa of Convolvulaceae. Leaves showed most of the phytochemicals than stems. The important phytochemicals in leaves were flavonoids, carbohydrates, alkaloids, saponins, tannins and phenolic compounds while those in stems were carbohydrates, saponins and phenolic compounds. Proteins and fixed oils were absent in the taxa studied. Conclusion: Phytochemical screening in the present study, revealed that maximum phytochemicals were present in leaves than in stems.
