Salvia divinorum and Mitragyna speciosa (“Kratom”), two unscheduled dietary supplements whose active agents are opioid receptor agonists, have discrete psychoactive effects that have contributed to their increasing popularity. Salvia divinorum contains the highly selective kappa- opioid receptor agonist salvinorin A; this compound produces visual hallucinations and synesthesia. Mitragynine, the major alkaloid identified from Kratom, has been reported as a partial opioid agonist producing… 
Clinical Pharmacology of the Dietary Supplement Kratom (Mitragyna speciosa)
TLDR
Until studies are conducted that define kratom's role in treating opioid withdrawal and/or other central nervous system conditions, kratom will likely remain available as a dietary supplement for the foreseeable future.
DARK Classics in Chemical Neuroscience: Kratom.
TLDR
The traditional and medicinal uses of kratom are reviewed along with the synthesis of its bioactive ingredients, their pharmacology, metabolism, and structure-activity relationships, and the importance in society of this currently controversial substance are discussed.
Neuropharmacology of the Naturally Occurring κ-Opioid Hallucinogen Salvinorin A
TLDR
Salvinorin A has therapeutic potential as a treatment for pain, mood and personality disorders, substance abuse, and gastrointestinal disturbances, and suggests that nonalkaloids are potential scaffolds for drug development for aminergic G-protein coupled receptors.
Abuse potential and adverse cognitive effects of mitragynine (kratom)
TLDR
Findings provide evidence for an addiction potential with cognitive impairments for mitragynine, which suggest its classification as a harmful drug.
Neurobiology of Kratom and its main alkaloid mitragynine
Pharmacokinetics and Pharmacodynamics of Salvinorin A and Salvia divinorum: Clinical and Forensic Aspects
TLDR
The aim of this work is to comprehensively review and discuss the toxicokinetics and toxicodynamics of S. divinorum and salvinorin A, highlighting their psychological, physiological, and toxic effects.
Pharmacology of Kratom: An Emerging Botanical Agent With Stimulant, Analgesic and Opioid-Like Effects
TLDR
Analyses of the medical literature and select Internet sites indicate that individuals in the United States are increasingly using kratom for the self-management of pain and opioid withdrawal.
Kratom (Mitragyna speciosa): worldwide issues.
PURPOSE OF REVIEW To inform readers about the increasingly popular Western dietary supplement, kratom (Mitragyna speciosa) and how the products are available in the Western world compared with

TLDR
Salvinorin A is the first naturally occurring nonnitrogenous opioid-receptor subtype-selective agonist for kappa opioid receptors, and may represent novel psychotherapeutic compounds for diseases manifested by perceptual distortions (e.g., schizophrenia, dementia, and bipolar disorders).

Salvinorin A is the first naturally occurring nonnitrogenous opioid-receptor subtype-selective agonist for κ opioid receptors and may represent novel psychotherapeutic compounds for diseases manifested by perceptual distortions (e.g., schizophrenia, dementia, and bipolar disorders).
Kappa-opioid receptor-mediated effects of the plant-derived hallucinogen, salvinorin A, on inverted screen performance in the mouse
TLDR
In the mouse, salvinorin A disrupted climbing behavior on an inverted screen task, indicating a rapid, but short-lived induction of sedation/motor incoordination and the possibility that the development of other diterpene-based opioids may yield important therapeutic compounds.

TLDR
It is concluded that SDE depressed enteric cholinergic transmission likely through activation of κ‐opioid receptors and this may provide the pharmacological basis underlying its traditional antidiarrhoeal use.
Pharmacokinetics of the plant‐derived κ‐opioid hallucinogen salvinorin A in nonhuman primates
TLDR
Pharmacokinetic differences were observed between males and females, suggesting potential sex differences in its pharmacologic effects, and Salvinorin B, the presumed major metabolite, is observed to accumulate ex vivo; however, in this study it never reached the limit of detection.
Use of nonprohibited hallucinogenic plants: increasing relevance for public health? A case report and literature review on the consumption of Salvia divinorum (Diviner's Sage).
TLDR
A mint plant, called diviner's sage ( Salvia divinorum), originally used in shamanic ceremonies of the Mazatec Indians of Mexico, is called attention to and physicians or psychotherapists are urged to take Salvia into consideration, when exploring young people for drug use.
Depressive-Like Effects of the κ-Opioid Receptor Agonist Salvinorin A on Behavior and Neurochemistry in Rats
TLDR
SalvA data provide additional support for the hypothesis that stimulation of brain κ-opioid receptors triggers depressive-like signs in rats and raise the possibility that decreases in extracellular concentrations of DA within the NAc contribute to these effects.
