Background/objectives: Chronic stress is a pervasive issue affecting individuals worldwide, with profound implications for mental and physical well-being. Panax ginseng, a widely used herbal supplement renowned for its adaptogenic properties, is hypothesized to alleviate some stress effects. This study aims to evaluate the impact of hydroponically grown Red Panax ginseng root powder with a high level of rare ginsenosides supplementation on perceived stress levels, as well as on the emotional and cognitive abilities of moderately stressed participants. Methods: A randomized, double-blind, controlled study was conducted with 149 participants. They were randomly assigned to either the Ginseng supplementation group (N = 72; 200 mg/day, including 24 mg of ginsenosides) or the Placebo group (N = 77). The intervention lasted for 3 weeks. The perceived stress level was measured at baseline (D0) and at the end of the intervention (D21) using a validated scale (PSS) alongside assessments of emotional (BDI and PANAS) and cognitive abilities (CANTAB subtests). Results: Significantly larger decreases in the PSS and negative affect score (PANAS) were observed following intervention in the Ginseng group compared with the Placebo group. Compared to the Placebo group, participants in the Ginseng group showed faster response latencies during a spatial planning task (OTSC subtest). In addition, there was a marginally larger decrease in the BDI score in the Ginseng group. Conclusions: These results confirm the emotional and cognitive benefits of Red Panax ginseng in moderately stressed adults and pave the way for further exploration of its use as a promising approach to improving psychological well-being.

Objectives: This study aimed to explore the effects of four days of Rhodiola Rosea (RR) supplementation on bench-press and bench-pull exercises under resting or mental fatigue conditions in young healthy individuals. Methods: Eighteen participants (seven women) visited the laboratory on five occasions separated by 7 days—one preliminary session and four experimental sessions. In the preliminary session, participants were familiarised with the Stroop and Multiple Object Tracking tests, after which their one-repetition maximum loads for bench presses and bench pulls were determined. The four experimental sessions had the same protocol, differing only in the supplement (RR or placebo) and mental task conditions (Stroop test or control video). Participants were assigned randomly and counterbalanced to each experimental condition: (I) RR and Stroop test, (II) RR and control video, (III) placebo and Stroop test, and (IV) placebo and control video. Results: The main findings indicate that RR supplementation has trivial-to-small effects in terms of mental fatigue, visuo-cognitive processing, or perceived exertion. However, RR was significantly superior to placebo on strength performance in the control video condition during some sets, as it increased the number of repetitions performed in the bench press and the fastest velocity in the bench pull. Out of 52 comparisons, 17 small effect sizes were observed, with 14 favouring RR and 3 favouring placebo, with the remaining differences being trivial. Conclusions: These results suggest that short-term RR supplementation is safe and provides its main ergogenic effects on physical performance rather than in visuo-cognitive or mental outcomes.

Long-lasting brain fatigue is a consequence of stroke or traumatic brain injury associated with emotional, psychological, and physical overload, distress in hypertension, atherosclerosis, viral infection, and aging-related chronic low-grade inflammatory disorders. The pathogenesis of brain fatigue is linked to disrupted neurotransmission, the glutamate-glutamine cycle imbalance, glucose metabolism, and ATP energy supply, which are associated with multiple molecular targets and signaling pathways in neuroendocrine-immune and blood circulation systems. Regeneration of damaged brain tissue is a long-lasting multistage process, including spontaneously regulating hypothalamus-pituitary (HPA) axis-controlled anabolic–catabolic homeostasis to recover harmonized sympathoadrenal system (SAS)-mediated function, brain energy supply, and deregulated gene expression in rehabilitation. The driving mechanism of spontaneous recovery and regeneration of brain tissue is a cross-talk of mediators of neuronal, microglia, immunocompetent, and endothelial cells collectively involved in neurogenesis and angiogenesis, which plant adaptogens can target. Adaptogens are small molecules of plant origin that increase the adaptability of cells and organisms to stress by interaction with the HPA axis and SAS of the stress system (neuroendocrine-immune and cardiovascular complex), targeting multiple mediators of adaptive GPCR signaling pathways. Two major groups of adaptogens comprise (i) phenolic phenethyl and phenylpropanoid derivatives and (ii) tetracyclic and pentacyclic glycosides, whose chemical structure can be distinguished as related correspondingly to (i) monoamine neurotransmitters of SAS (epinephrine, norepinephrine, and dopamine) and (ii) steroid hormones (cortisol, testosterone, and estradiol). In this narrative review, we discuss (i) the multitarget mechanism of integrated pharmacological activity of botanical adaptogens in stress overload, ischemic stroke, and long-lasting brain fatigue; (ii) the time-dependent dual response of physiological regulatory systems to adaptogens to support homeostasis in chronic stress and overload; and (iii) the dual dose-dependent reversal (hormetic) effect of botanical adaptogens. This narrative review shows that the adaptogenic concept cannot be reduced and rectified to the various effects of adaptogens on selected molecular targets or specific modes of action without estimating their interactions within the networks of mediators of the neuroendocrine-immune complex that, in turn, regulates other pharmacological systems (cardiovascular, gastrointestinal, reproductive systems) due to numerous intra- and extracellular communications and feedback regulations. These interactions result in polyvalent action and the pleiotropic pharmacological activity of adaptogens, which is essential for characterizing adaptogens as distinct types of botanicals. They trigger the defense adaptive stress response that leads to the extension of the limits of resilience to overload, inducing brain fatigue and mental disorders. For the first time, this review justifies the neurogenesis potential of adaptogens, particularly the botanical hybrid preparation (BHP) of Arctic Root and Ashwagandha, providing a rationale for potential use in individuals experiencing long-lasting brain fatigue. The review provided insight into future research on the network pharmacology of adaptogens in preventing and rehabilitating long-lasting brain fatigue following stroke, trauma, and viral infections.

Mushrooms are indeed gaining attention for their unique therapeutic and nutritional qualities, especially in fermented drinks. This trend builds on their historical use in traditional medicine, especially within Eastern practices, where mushrooms like reishi, chaga, shiitake, oyster, lion’s mane, and cordyceps are known for their immune-boosting, anti-inflammatory, and adaptogenic properties. This narrative review highlights the growing interest in the use of mushrooms as functional ingredients in fermented beverages, emphasizing their technological and functional advantages. Fermentation significantly enhances the nutritional content and bioavailability of mushrooms, making it an ideal method to maximize the health benefits and sensory appeal of mushroom-based beverages. Microbial activity breaks down complex compounds in mushrooms, making their bioactive components more accessible for absorption; bringing unique flavors, aromas, and textures; and creating a rich-sensory experience while offering potential health benefits. Mushrooms can also improve the stability and shelf life of fermented beverages due to the presence of antimicrobial and antioxidant compounds, adding another valuable benefit to their use in functional beverages. However, despite their potential, further research is needed to fully understand their impact on health and to refine production techniques for optimal quality and consistency. This review provides a comprehensive overview of the current knowledge of mushroom-fermented beverages, highlighting both the known benefits and research gaps that require further investigation. Given the early stage of this field, the review emphasizes the importance of the additional investigation to unlock the full potential of mushrooms in functional beverage applications. Full article

Salidroside, a phenolic compound isolated from various Rhodiola plants, is the principal active constituent of Traditional Chinese Medicine known for its adaptogenic properties. Due to the challenging environment of Rhodiola species, such as high altitude, high radiation, drought, and hypoxia, the source of salidroside is scarce. However, numerous studies have shown that salidroside has a range of biological activities, including cardiovascular and central nervous system activity, and anti-hypoxia, anti-inflammatory, and anti-aging activities. Although previous studies have partially summarized the pharmacological effects of salidroside, the overall pharmacological effects have not been analyzed. Hence, this review will systematically summarize the isolation, purification, synthesis, derivatization, pharmacological activity, pharmacokinetics, clinical application, and safety of salidroside. It is expected to provide new insights for the further research and pharmaceutical development of salidroside. Full article

Agricultural and industrial activities are increasing pollution of water bodies with low doses of xenobiotics that have detrimental effects on aquaculture. The aim of this work was to determine the possibility of using Levilactobacillus brevis 47f culture in fish aquaculture under the influence of low doses of xenobiotics as an adaptogen. An increase in the survival of Danio rerio individuals exposed to the xenobiotic bisphenol A solution and fed with the L. brevis 47f was shown compared to control groups and, at the same time, the cytokine profile in the intestinal tissues of Danio rerio was also investigated. Analysis of differential gene expression of the L. brevis 47f grown under the action of high concentrations of bisphenol A showed changes in mRNA levels of a number of genes, including genes of various transport proteins, genes involved in fatty acid synthesis, genes of transcriptional regulators, genes of the arabinose operon, and the oppA gene. The identification of L. brevis 47f proteins from polyacrylamide gel by mass spectrometry revealed L-arabinose isomerase, Clp chaperone subunit, ATP synthase subunits, pentose phosphate pathway and glycolysis enzyme proteins, which are likely part of the L. brevis 47f strain’s anti-stress response, but probably do not affect its adaptogenic activity toward Danio rerio.

Depression is one of the most common diseases in the world, and it is also the most common mental disorder. Depressive disorders are a real threat not only to individuals, but also to the general population. This disease is a leading cause of disability and inability to work. Due to the numerous side effects of conventional drugs, attention is increasingly being paid to other solutions, including herbal medicines. Many plant species are known for their traditional uses in the treatment of anxiety, insomnia, and depression. The clinically proven effects of adaptogenic raw materials on depression symptoms are probably related to the positive impact of some secondary metabolites (terpenoids, alkaloids, glucosinolates, phenols). Currently, it is emphasized that in many cases the antioxidant and anti-inflammatory properties of plant substances play a protective role at the neurocellular level. Among the medicinal plants analyzed in clinical trials for the treatment of depression, the following seem to be particularly interesting: saffron (Crocus L.), turmeric (Curcuma L.), ginkgo (Ginkgo L.), St. John’s wort (Hypericum L.), and passionflower (Passiflora L.), which have broad and strong biological activity, well-documented history of action and use, and effectiveness in preventing and/or treating anxiety and depression. These plants are still in the sphere of biochemical and phytopharmaceutical research, the results of which are very promising. Full article

Lessertia frutescens (synonym Sutherlandia frutescens) is an important South African medicinal plant used traditionally to treat different human pathologies and is considered an adaptogenic plant. This study sought to isolate compounds from the plant and determine their protective potentials using SH-SY5Y cells and MPP⁺ (1-methyl-4-phenylpyridinium) to mimic Parkinson’s disease. The phytochemical analysis of a 70% aqueous methanolic extract of L. frutescens leaves resulted in the isolation and identification of 11 pure compounds (1–11), among which compounds 1 and 2 were identified as new metabolites. The new compounds were characterised using IR, UV, NMR, and HRESIMS and were given the trivial names lessertiosides A (1) and B (2). Additionally, the flavonoids 8-methoxyvestitol (7) and mucronulatol (8) were isolated for the first time from the plant. The biological actions show that the isolated compounds had negligible toxicity on SH-SY5Y cells and improved cell viability in the cells exposed to MPP⁺. Furthermore, as a mechanism of action, the compounds could sustain cellular ATP generation and prevent MPP⁺-induced apoptotic cell death. Our findings provide evidence for the neuroprotective properties of compounds isolated from L. frutescens in MPP⁺-induced neuronal damage for the first time and create an avenue for these compounds to be further investigated to elucidate their molecular targets.

Deep eutectic solvents (DESs) have attracted attention from researchers as novel compounds for extracting active substances because of their negligible toxicity, polarity, and ability to be tailored depending on the experiment. In this review, we discuss deep eutectic solvents as a promising medium for the extraction of adaptogenic compounds. In comparison to traditional methods, extraction with the use of DESs is a great alternative to the excessive usage of harmful organic solvents. It can be conducted in mild conditions, and DESs can be designed with different precursors, enhancing their versatility. Adaptogenic herbs have a long medicinal history, especially in Eastern Asia. They exhibit unique properties through the active compounds in their structures, including saponins, flavonoids, polysaccharides, and alkaloids. Therefore, they demonstrate a wide range of pharmaceutical effects, such as anti-inflammatory, antibacterial, and anticancer abilities. Since ancient times, many different adaptogenic herbs have been discovered and are well known, including Panax ginseng, Scutellaria baicalensis, and Schisandra chinensis. Active compounds can be extracted using standard methods, such as hydrolyzation, maceration, and conventional reflux extraction. However, due to the limitations of classical processing technologies, there has been a need to develop new and eco-friendly methods. We focus on the types of solvents, extraction efficiency, properties, and applications of the obtained active compounds. This review highlights the potential of DESs as eco-friendly alternatives for extracting bioactive compounds. Full article

Eleutherococcus senticosus (Rupr. et Maxim.) Maxim. (ES) has gained popularity for its adaptogenic, immunostimulant, and anti-inflammatory properties. Because of overexploitation of the roots, the species is considered to be endangered and has been put on the Red List in some countries (e.g., the Republic of Korea). Therefore, the fruits of E. senticosus might be explored as a new sustainable source of compounds with adaptogenic activity. This study aimed to assess the chemical composition and the safety profile (hepatotoxicity, blood morphology, biochemical parameters of blood plasma) of E. senticosus fruit intractum in Balb/c mice after oral administration of 750 and 1500 mg/kg b.w. UHPLC analysis coupled with DAD and MS detectors was used to quantify the metabolites. For the first time, oleanolic and ursolic acids were quantified in the intractum (16.01 ± 1.3 and 2.21 ± 0.17 µg/g of oleanolic and ursolic acids, respectively). Regarding polyphenols, chlorogenic acid (0.92 mg/g of dried extract), caffeic acid (0.43 mg/g), dicaffeoylquinic acids (in total: 1.27 mg/g), and an unidentified caffeic acid ester (0.81 mg/g) were identified. The results in Balb/c mice revealed that the intractum does not cause significant variations in red blood cells parameters. In turn, a significant decrease in the total number of leukocytes was observed (5.8 × 10³ µL), with a percentage increase in lymphocytes among the groups (80.2, 81.8, and 82.6). The ability of the intractum to decrease alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels may indicate its anti-inflammatory activity. Our observations justify that the fruits of E. senticosus are safe in the doses used and do not cause significant changes in the activity of the liver enzymes or in blood parameters. Full article

Rhodiola rosea L. is recognized for its adaptogenic properties and ability to promote muscle health, function and recovery from exercise. The plethora of biological effects of this plant is ascribed to the synergism existing among the molecules composing its phytocomplex. In this manuscript, we analyze the activity of a bioactive fraction extracted from Rhodiola rosea L. controlled cultivation. Biological assays were performed on human skeletal myoblasts and revealed that the extract is able to modulate in vitro expression of transcription factors, namely Pax7 and myoD, involved in muscle differentiation and recovery. The extract also promotes ROS scavenging, ATP production and mitochondrial respiration. Untargeted metabolomics further reveals that the mechanism underpinning the plant involves the synergistic interconnection between antioxidant enzymes and the folic/acid polyamine pathway. Finally, by examining the phytochemical profiles of the extract, we identify the specific combination of secondary plant metabolites contributing to muscle repair, recovery from stress and regeneration.

Withania somnifera, commonly known as Ashwagandha, has been popular for many years. Numerous studies have shown that the extract of this plant, due to its wealth of active substances, can induce anti-inflammatory, neuroprotective, immunomodulatory, hepatoprotective, cardioprotective, anti-diabetic, adaptogenic, anti-arthritic, anti-stress, and antimicrobial effects. This review examines the impact of Ashwagandha extract on the vascular endothelium, inflammation, lipid metabolism, and cardiovascular outcomes. Studies have shown that Ashwagandha extracts exhibit an anti-angiogenic effect by inhibiting vascular endothelial growth factor (VEGF)-induced capillary sprouting and formation by lowering the mean density of microvessels. Furthermore, the results of numerous studies highlight the anti-inflammatory role of Ashwagandha extract, as the action of this plant causes a decrease in the expression of pro-inflammatory cytokines. Interestingly, withanolides, present in Ashwagandha root, have shown the ability to inhibit the differentiation of preadipocytes into adipocytes. Research results have also proved that W. somnifera demonstrates cardioprotective effects due to its antioxidant properties and reduces ischemia/reperfusion-induced apoptosis. It seems that this plant can be successfully used as a potential treatment for several conditions, mainly those with increased inflammation. More research is needed to elucidate the exact mechanisms by which the substances contained in W. somnifera extracts can act in the human body. Full article

Rhodiola rosea, a long-lived herbaceous plant from the Crassulaceae group, contains the active compound salidroside, recognized as an adaptogen with significant therapeutic potential for bone metabolism. Salidroside promotes osteoblast proliferation and differentiation by activating critical signaling pathways, including bone morphogenetic protein-2 and adenosine monophosphate-activated protein kinase, essential for bone formation and growth. It enhances osteogenic activity by increasing alkaline phosphatase activity and mineralization markers, while upregulating key regulatory proteins including runt-related transcription factor 2 and osterix. Additionally, salidroside facilitates angiogenesis via the hypoxia-inducible factor 1-alpha and vascular endothelial growth factor pathway, crucial for coupling bone development with vascular support. Its antioxidant properties offer protection against bone loss by reducing oxidative stress and promoting osteogenic differentiation through the nuclear factor erythroid 2-related factor 2 pathway. Salidroside has the capability to counteract the negative effects of glucocorticoids on bone cells and prevents steroid-induced osteonecrosis. Additionally, it exhibits multifaceted anti-inflammatory actions, notably through the inhibition of tumor necrosis factor-alpha and interleukin-6 expression, while enhancing the expression of interleukin-10. This publication presents a comprehensive review of the literature on the impact of salidroside on various aspects of bone tissue metabolism, emphasizing its potential role in the prevention and treatment of osteoporosis and other diseases affecting bone physiology.
