Ginger (Zingiber officinale Roscoe) has been widely recognized for its antioxidant properties, primarily attributed to its phenolic compounds such as gingerols and shogaols. However, limited data exist regarding how different pharmaceutical forms influence the bioaccessibility and antioxidant efficacy of these compounds. This study aimed to evaluate the antioxidant capacity and bioaccessibility of ginger in different pharmaceutical forms—capsules (20 mg, 40 mg, and 80 mg), a pure powdered extract, and a liquid formulation—standardized to ≥6% gingerols. The phenolic profile of each formulation was characterized using HPLC-DAD (High-Performance Liquid Chromatography with Diode Array Detection), followed by the evaluation of antioxidant capacity through DPPH (2,2-Diphenyl-1-picrylhydrazyl) and ORAC (Oxygen Radical Absorbance Capacity) assays, and the assessment of bioaccessibility via an in vitro digestion model. The results demonstrated that antioxidant activity was positively correlated with extract concentration and was highest in the liquid formulation (426.0 ± 0.05 µmol Trolox equivalents (TE) and 11,336.7 ± 0.20 µmol TE in the DPPH and ORAC assays, respectively). The bioaccessibility of 6-gingerol and 6-shogaol significantly increased in the liquid form, reaching 23.44% and 11.31%, respectively, compared to ≤4% in the pure extract. These findings highlight the influence of the formulation matrix on compound release and support the use of liquid preparations to enhance the functional efficacy of ginger-derived nutraceuticals. This standardized comparative approach, using formulations derived from the same extract, offers new insights into how the delivery matrix influences the functional performance of ginger compounds, providing guidance for the development of more effective nutraceutical strategies.

Obesity is a global public health concern characterized by low-grade chronic inflammation and metabolic dysregulation. Ginger (Zingiber officinale Roscoe) contains bioactive compounds that have demonstrated potential anti-obesity and immunomodulatory effects. This review aims to synthesize the current evidence regarding the immunometabolic effects of ginger supplementation in obesity, integrating findings from in vitro, in vivo, and clinical studies. Evidence indicates that ginger and its principal compounds, such as 6-gingerol and 6-shogaol, inhibit adipocyte differentiation and lipid accumulation, reduce pro-inflammatory cytokines including tumor necrosis factor alpha (TNF-α), interleukin-6 (IL-6), and the chemoattractant protein of monocytes-1 (MCP-1), improve lipid profiles, and enhance anti-inflammatory adipokines like adiponectin. Clinical trials report improvements in insulin sensitivity, reductions in inflammatory markers, and body weight management in individuals with obesity. This review paper also highlights the cellular and molecular mechanisms of immunometabolic effects of ginger and its bioactive compounds. Therefore, ginger supplementation exhibits promising immunometabolic effects with the potential to support the prevention and treatment of obesity and its comorbidities. However, further rigorous clinical trials are necessary to confirm its efficacy and safety as well as its role in complementing existing strategies for obesity management. Full article

With increasing concerns over antibiotic resistance in livestock, there is an urgent need for sustainable alternatives to enhance health and productivity in poultry production. Ginger (Zingiber officinale Roscoe), a phytobiotic recognized for its diverse health benefits, including growth promotion and the improvement of intestinal function, was evaluated for its efficacy. This study investigated the effects of standardized ginger extract on gut morphology, microbiota composition, and growth performance in broiler chickens. A total of 200 day-old (Ross 308) broiler chicks were randomly assigned to four dietary groups: a control group receiving a basal diet and three experimental groups receiving a basal diet supplemented with 2.5 g/kg, 5 g/kg, and 10 g/kg of ginger extract. The performance results demonstrated that dietary ginger supplementation at 5 g/kg significantly improved feed efficiency without adversely affecting final body weight (p < 0.01). Feed intake in broilers was significantly reduced by higher doses of ginger extract (p < 0.01). Broiler chickens supplemented with 5 g/kg of ginger exhibited a significantly higher villous height-to-crypt depth ratio in the duodenum and jejunum (p < 0.05). Groups supplemented with 5 g/kg and 10 g/kg of ginger extract demonstrated a significant decrease in the relative abundance of Proteobacteria and an increase in the proportion of Firmicutes (p < 0.05). In conclusion, the addition of ginger extract at 5 g/kg resulted in improved feed efficiency, intestinal morphology, and microbiota composition. Full article

Kombucha is a sweetened tea infusion fermented using a symbiotic culture of bacteria and yeast (SCOBY). Recently, kombucha has gained popularity due to its potential health benefits, attributed to its high antioxidant and probiotic properties. The aim of this research was to formulate a novel antioxidant-rich beverage with symbiotic benefits by utilizing ingredients such as Laminaria digitata (brown seaweed), cinnamon, and lavender adjuncts, alongside alternative substrates like acacia honey and conventionally used ingredients such as ginger (Zingiber officinale Roscoe). This study comprehensively evaluated parameters including pH levels, acidity, alcohol content, color, and antioxidant potential of the beverages. All kombucha beverages exhibited significantly high antioxidant potential levels, particularly in Honey Kombucha (HK) samples, which ranged between 164.44 and 164.78% 2,2-Diphenyl-1-picrylhydrazyl (DPPH) inhibition, and 155.44–155.29 µg Trolox Equivalent (TE)/mL for the Ferric-reducing antioxidant power (FRAP) assay on days 3 and 7. Sugar Kombucha Seaweed (SKS) and Sugar Kombucha Cinnamon (SKC) samples received the highest acceptability for flavor from the sensory panel, with scores of 87.5% and 70%, respectively. However, Honey Kombucha Ginger (HKG) received the lowest acceptability with only 12.5%. The added adjuncts and substrates significantly influenced the antioxidant potential compared to plain unfermented tea (PT). This research paper outlines well-characterized fermentation process for formulating health-promoting beverages utilizing locally sourced ingredients. Full article

Cognitive problems are associated with impaired learning ability and memory dysfunction. Neuroinflammation has been identified as an important factor in the progression of anxiety and depressive disorders. Zingerone is a phenolic alkanone derived from ginger (Zingiber officinale Roscoe), which is known for its antioxidant and anti-inflammatory properties. A number of studies have investigated the effect of zingerone on neuroinflammation and cognitive impairment. However, this evidence has not been systematically reviewed. This study sought to systematically review the effect of zingerone on neuroinflammation and neurobehavioural changes associated with memory and learning impairment and anxiety-like and depressive-like behaviours. A systematic review was conducted using pre-defined search criteria on Google Scholar, Scopus and Web of Science. The records obtained were screened based on inclusion criteria, and data was extracted from the included studies. Out of the 482 studies that were identified, only 9 studies met the inclusion criteria. Neuroinflammatory markers such as interleukin 1β (IL-1β), interleukin 6 (IL-6), tumour necrosis factor-alpha (TNF-α) and ionized calcium binding adaptor molecule (IBA-1), as well as behavioural parameters including Morris water maze, Y-Maze, recognition test, passive avoidance test, elevated plus maze, sucrose preference test and forced swimming test were measured. Zingerone exhibited anti-neuroinflammatory effects by improving IL-1β, IL-6 and TNF-α levels. However, zingerone did not show any significant changes on activated microglia. The anti-neuroinflammatory mechanisms of zingerone were linked to the inhibition of nuclear factor kappa B (NF-kB) activation and the NOD-like receptor family, pyrin domain-containing 3 (NLRP3) inflammasome, as well as the reduction in neuronal nitric oxide synthase (nNOS). The anxiolytic and anti-depressive effects of zingerone were also associated with an improvement in cortical cholinergic transmission, the mitigation of oxidative stress and the upregulation of neurotransmitters such as serotonin and dopamine. This review provides scientific evidence on the cognitive enhancing and neuroprotective mechanisms of zingerone, which may be beneficial for future experimental investigations. Full article

Background/Objectives: Zingiber officinale Roscoe (Zingiberaceae) is widely recognized for its diverse biological activities; however, the stability and bioavailability of its bioactive compounds remain significant challenges. This study aimed to investigate an innovative approach to enhance the stability and efficacy of Z. officinale phytoconstituents through advanced encapsulation techniques. Methods: Two novel carrier systems were developed: (i) direct micro-spray encapsulation of Z. officinale in maltodextrin (MZO) and (ii) a two-step process involving the creation of a kaolinite-based phytocarrier system (ZO–kaolinite), followed by micro-spray encapsulation in maltodextrin to form the MZO–kaolinite system. Results: Comprehensive chemical profiling using GC–MS and ESI–QTOF–MS identified 105 phytochemicals, including terpenoids, gingerols, shogaols, flavonoids, and phenolic acids. Morphostructural analyses (XRD, FTIR, Raman, SEM) confirmed the successful development of the newly engineered kaolinite carrier systems (ZO–kaolinite and MZO–kaolinite systems). Both the ZO–kaolinite and MZO–kaolinite systems exhibited superior antioxidant activity, potent antimicrobial efficacy against major bacterial pathogens (Staphylococcus aureus, Enterococcus faecalis, Bacillus cereus, Klebsiella pneumoniae, Pseudomonas aeruginosa, Escherichia coli), and enhanced cytotoxicity against MCF-7, HCT-116, and HeLa cancer cell lines. Conclusions: This study underscores the synergistic action of kaolinite and maltodextrin in developing multifunctional therapeutic systems, emphasizing the importance of phytoconstituent stabilization and nanotechnology in addressing antimicrobial resistance and advancing innovative medical applications.

Ginger (Zingiber officinale Roscoe), valued both for its medicinal and culinary uses, can be adversely affected by abiotic stresses such as high temperature and drought, which can impact its growth and development. The HSP90 gene family has been recognized as a crucial element for enhancing heat and drought resistance in plants. Nevertheless, no studies have yet reported on the HSP90 gene family in ginger. This study investigates the HSP90 gene family in ginger and its crucial role in the plant’s responses to abiotic stresses. A total of 11 ZoHSP90 members were identified in the ginger genome, and these genes were unevenly distributed across five chromosomes. Bioinformatics analyses revealed that the HSP90 proteins in ginger vary in size, ranging from 306 to 886 amino acids. These proteins are predominantly located in the cytoplasm, endoplasmic reticulum, and mitochondria. Notably, ten conserved motifs were identified, with variations in motif distribution correlating with phylogenetic relationships among the genes. Furthermore, the gene structure analysis indicated differences in exon numbers, which may reflect specialized regulatory mechanisms and functional differentiation among the ZoHSP90 genes. Cis-acting elements within the promoter regions of the ZoHSP90 genes were identified, and their involvement in stress responses and hormonal signaling pathways was revealed. These elements are critical for regulating gene expression patterns in response to environmental stimuli, such as methyl jasmonate, salicylic acid, and abscisic acid. The presence of these elements indicates that ZoHSP90 genes play significant regulatory roles in plant adaptation to environmental changes. Expression profiling of the ZoHSP90 genes under various abiotic stress conditions demonstrated tissue specificity and dynamic regulation. Different ZoHSP90 genes exhibited distinct expression patterns in response to low-temperature, drought, high-temperature, and salt stresses. This suggests that the HSP90 gene family in ginger possesses both conserved functions and species-specific adaptations to optimize stress responses. Overall, this research provides valuable insights into the molecular functions of the HSP90 gene family in ginger and lays the groundwork for future studies aimed at enhancing crop resilience through genetic engineering. The findings contribute to a deeper understanding of plant adaptability to environmental stressors, which is crucial for improving agricultural productivity in the face of climate change.

Background: In many African areas, herbal products still represent a significant source of healthcare. However, a major gender bias is evident in the literature, as most of the work is carried out by male researchers, collecting data from male traditional practitioners, and thus often neglecting women’s specific health issues. This warrants a detailed review of the current knowledge about the major medicinal plants historically and still used for women’s health. Objective: This study aims to compile and critically analyze published data on the use of traditional herbal remedies by African women in addressing specific health conditions, in order to evaluate the potential of traditional medicine as a viable alternative or complementary approach to modern healthcare for women globally. Methods: Data were retrieved from databases by combining the following relevant keywords: “abortion, adverse, Africa, attendant, birth, botanical, delivery, developing, drug, ethnomedicine, ethnopharmacology, folk, gynecological, healing, infertility, herb, indigenous, lactation, medicine, native, obstetric, phytomedicine, plant, pregnancy, remedy, side, sub-Saharan, traditional, treatment, women”. Results: More than 125 studies, carried out across 12 African nations, revealed that up to 80% of African women resort to herbal medicines. An estimated 200 medicinally important plant species are reported to be utilized by women in different African countries, including Benin, Cameroon, Côte d’Ivoire, Egypt, Ethiopia, Ghana, Kenya, Mali, Nigeria, South Africa, Tanzania, and Zimbabwe. These herbs have many applications, mostly focused on infertility, pregnancy, painful menstruation, breast feeding, breast cancer, and contraception. Interestingly, according to their occurrence of usage, the plants most commonly reported for these conditions that are important to women are ambivalent plants (i.e., used both as foods and medicines) that include Zingiber officinale Roscoe, Allium sativum L., Cucurbita pepo L., and Ricinus communis L. Conclusions: Even though most women, in most African countries, do use traditional medicine, the amount of work published remains quite limited and no data are available in many countries. Therefore, it is desirable to expand African studies in this direction. Full article

This study investigated the therapeutic effects of water extracts from Zingiber officinale Roscoe (ginger) and Cornus officinalis Siebold and Zucc. fruits (COF) water extracts on depression-like behavior and metabolic dysfunction in estrogen-deficient rats exposed to chronic mild stress (CMS). Network pharmacology analysis identified three bioactive compounds in ginger and four in COF, with 11 overlapping targets linked to both depression and metabolic pathways, primarily involving NR3C1, HTR2A, MAOA, and SLC6A4 genes associated with hypothalamic–pituitary–adrenal (HPA) axis regulation and neurotransmitter modulation. Ovariectomized rats received 200 mg/kg/day of ginger or COF extracts for 7 weeks, with a 4-week CMS protocol initiated at week 3. Both extracts significantly improved depression-like behaviors, memory performance, glucose tolerance, lipid profiles, and bone mineral density, normalized HPA axis markers (corticosterone and ACTH), and increased hippocampal serotonin and dopamine levels. Ginger demonstrated greater efficacy in improving memory and metabolic outcomes compared to COF. Molecular docking further validated these findings, revealing strong and stable interactions between key phytochemicals—such as hydroxygenkwanin and telocinobufagin—and target proteins MAOA, HTR2A, and NR3C1, supporting their mechanistic role in stress and mood regulation. These results support supplementing ginger and COF extracts as promising botanical interventions for estrogen-deficiency-related mood and metabolic disorders, with potential clinical application at a human-equivalent dose of 1.5 g/day.

Aphis gossypii Glover (Homoptera: Aphidinae), a major pest of Chinese pepper (Zanthoxylum bungeanum Maxim), causes significant agricultural damage. Ginger (Zingiber officinale Roscoe) has shown potential as a source for developing botanical pesticides due to its strong bacteriostatic and insecticidal properties; however, the underlying mechanisms remain poorly understood. This study evaluated the repellent activity of ginger shoot extract (GSE) across four solvent phases—petroleum ether, trichloromethane, ethyl acetate, and methanol—against A. gossypii. The results demonstrated that GSE exhibited significant repellent effects, with the methanol phase showing the most pronounced activity. Twelve fractions were chromatographically separated from the methanol phase, and electroantennography (EAG) analysis revealed that fraction 4 induced strong EAG responses in both winged and wingless aphids. Further identification of active compounds in fraction 4 by gas chromatography–mass spectrometry (GC–MS) indicated the presence of terpenes, aromatics, alkanes, esters, and phenols as major constituents. Subsequent EAG analysis identified several key compounds—octahydro-pentalene (C1), (Z)-cyclooctene (C2), dimethylstyrene (C3), tetramethyl-heptadecane (C5), tetrahydro-naphthalene (C6), and heptacosane (C9)—as responsible for eliciting EAG responses in both aphid forms. Additionally, results from Y-tube olfactometer assays showed that (Z)-cyclooctene and heptacosane were significantly attractive, while octahydro-pentalene acted as a strong repellent to both winged and wingless aphids. These findings offer valuable insights for the development of synthetic attractants and repellents for A. gossypii and provide a theoretical foundation for utilizing ginger in the creation of botanical pesticides targeting this pest.

As a product and reproductive organ of ginger (Zingiber officinale Roscoe), the degree of rhizome bulking is a key factor in determining the yield and economic value of ginger. There are few studies on the regulatory mechanism of rhizome bulking in ginger. This study aims to identify the key hormone that regulates ginger rhizome bulking and to screen for critical hormone-associated genes. As research subjects, two ginger accessions—large (L) with a thickened rhizome and small (S) with a slender rhizome—were derived from the same parent plant. The ploidy differences between the two determine variations in gene dosage as well as differential expression patterns. The levels of eight hormones in the rhizome of L and S during different growth stages were analyzed. Differentially expressed genes (DEGs) were identified by combining third-generation transcriptome sequencing technology (PacBio SMART) with quantitative real time PCR (qRT-PCR). Through screening methods such as Orthogonal Partial Least Squares Discriminant Analysis (OPLS-DA), auxin, cytokinin, and salicylic acid were identified as the key differential hormones across various growth periods. Among these, changes in IAA level showed a positive correlation with rhizome bulking. Among them, change in IAA levels was positively correlated with the degree of rhizome bulking. Transcriptome analysis combined with qRT-PCR revealed that the auxin response factor genes ZoARF7 and ZoARF23 are likely to act as positive regulators of rhizome bulking. This study provides a theoretical foundation for elucidating the molecular mechanisms underlying hormone-mediated rhizome bulking in ginger. Full article

In this study, we performed supercritical CO₂ extraction of oleoresin from Peruvian ginger, focusing on the extraction yield, total polyphenol content, antioxidant capacity, and contents of gingerol and shogaol. The temperature (40 to 50 °C), pressure (80 to 250 bar), CO₂ flow rate (2 and 8 ft³/h) and extraction time (10 to 360 min) were evaluated in three steps. The extraction yield was influenced by the temperature, pressure, flow rate and extraction time. Oleoresin extracts were obtained from 150 to 250 bar. The supercritical extraction conditions selected for the recovery of the oleoresin extract were 50 °C, 250 bar, 8 ft³/h and 360 min, resulting in an extraction yield of 25.99 ± 0.13 mg extracts/g dry basis, a total polyphenol content of 171.65 ± 2.12 mg of gallic acid equivalent (GAE)/g extract, an antioxidant capacity expressed as a half-maximal inhibitory concentration (IC₅₀) of 1.02 ± 0.01 mg extract/mL methanol and a Ferric Reducing Antioxidant Power (FRAP) value of 368.14 ± 60.95 mg Trolox/g extract. The contents of gingerols and shogaols in the supercritical extract were 254.71 ± 33.79 mg of 6-gingerol/g extract, 24.46 ± 3.41 mg of 6-shogaol/g extract, 9.63 ± 2.51 mg of 8-gingerol/g extract, 51.01 ± 9.39 mg of 8-shogaol/g extract, 27.47 ± 5.06 mg of 10-gingerol/g extract and 20.11 ± 4.62 mg of 10-shogaol/g extract. There was no reduction in the total polyphenol content or antioxidant capacity according to the IC₅₀ and FRAP assays, under storage conditions of 0 °C, 20 °C and 40 °C after 180 days; this indicates that the oleoresin obtained using supercritical CO₂ extraction could be used as an additive in food products.

Background/Objectives: Multiple sclerosis (MS) is a chronic inflammatory disease of the central nervous system characterized by demyelination and neuronal damage. Current MS therapies are unsatisfactory, and new therapies are encouraged. A correlation between nutritional intake and MS has been speculated. Supplementation of approved immunomodulatory therapy with herbal medicines possessing antioxidant and anti-inflammatory activities could provide benefits to MS patients. Ginger is one of the most widely consumed dietary supplements in the world, commonly used in traditional medicine. Studies demonstrated that ginger may also be beneficial in the management of neurodegenerative diseases. The aim of this study is to investigate the MS therapeutic potential of ginger. Methods: A standardized Zingiber officinale Roscoe extract (ZOE) was orally administered for 14 days. Two experimental autoimmune encephalomyelitis (EAE) models in mice were used. The PLP_139-151-EAE relapsing-remitting model and MOG_35–55-EAE chronic model. Clinical score, von Frey, hot plate, and rotarod tests were used for behavioral tests. ELISA and Western blotting were used to measure cytokines levels. Evans Blue content was determined spectrophotometrically. Results: ZOE attenuated motor disability and pain hypersensitivity in both models had no effect on body weight loss. ZOE reduced the blood–brain barrier (BBB) permeability in the PLP-EAE models and reduced levels of circulating cytokines (Il-6, IL-17) in the MOG-EAE model. ZOE attenuated spinal cytokines overexpression in both models. Conclusions: ZOE improves EAE symptoms and attenuates the proinflammatory response in both models, representing a promising nutraceutical support to the conventional therapeutic approach to MS.

Background/Objectives: Individuals with special metabolic demands are at risk of deficiencies in fat-soluble vitamins, which can be counteracted via supplementation. Here, we tested the ability of micellization alone or in combination with selected natural plant extracts to increase the intestinal absorption and bioefficacy of fat-soluble vitamins. Methods: Micellated and nonmicellated vitamins D3 (cholecalciferol), D2 (ergocalciferol), E (alpha tocopheryl acetate), and K2 (menaquionone-7) were tested in intestinal Caco-2 or buccal TR146 cells in combination with curcuma (Curcuma longa), black pepper (Piper nigrum), or ginger (Zingiber officinale Roscoe) plant extracts. The vitamin uptake was quantified via HPLC-MS, and bioefficacy was assessed via gene expression analyses or the Griess assay for nitric oxide generation. Results: Micellization increased the uptake of vitamin D into buccal and intestinal cells, with vitamin D3 being more efficient than vitamin D2 in increasing the expression of genes involved in calcium transport. The micellization of vitamin E acetate increased its uptake and conversion into biologically active free vitamin E in intestinal cells only. The vitamin K2 uptake into buccal and intestinal cells was increased via micellization. Plant extracts increased the uptake of select micellated vitamins, with no plant extract being effective in combination with all vitamins. The curcuma extract increased the uptake of vitamins D2/D3 but not their bioefficacy. Black pepper and ginger extracts increased the uptake of vitamin E acetate into intestinal cells but failed to increase its conversion into free vitamin E. The ginger extract augmented the uptake of vitamin K2 and increased NO generation additively. Conclusions: Our data substantiate the positive effects of micellization on fat-soluble vitamin absorption and bioefficacy in vitro. While the application of plant extracts in addition to micellization to further increase bioefficacy is an interesting approach, further studies are warranted to understand vitamin-specific interactions and translation into increased bioefficacy.

Radiotherapy is a powerful tumor therapeutic strategy for gastric cancer patients. However, radioresistance is a major obstacle to kill cancer cells. Ginger (Zingiber officinale Roscoe) exerts a potential function in various cancers and is a noble combined therapy to overcome radioresistance in gastric cancer radiotherapy. In this study, we suggested that 8-shogaol, a monomethoxybenzene compound extracted from Zingiber officinale Roscoe, has an anti-cancer and anti-inflammatory activity. In lipopolysaccharide (LPS)-induced inflammatory murine models in vivo and in vitro, 8-shogaol suppressed LPS-mediated cytokine production, including COX-2, TNFα, IL-6, and IL-1β. In xenograft mouse models of AGS gastric cancer cell lines, 8-shogaol reduced tumor volume. In gastric cancer cell lines AGS and NCI-N87, 8-shogaol reduced cell viability and increased caspase-3 activity and cytotoxicity LDH. However, combined with Z-VAD-FMK, 8-shogaol blocked caspase-dependent apoptotic cell death. 8-Shogaol induced intracellular reactive oxygen species (ROS) production, intracellular calcium (Ca²⁺) release, and endoplasmic reticulum (ER) stress response via the PERK-CHOP signaling pathway. Thapsigargin (TG), an ER stressor, mediated synergistic apoptosis and cell death in 8-shogaol-treated AGS and NCI-N87 cell lines. Nevertheless, loss of PERK or CHOP function suppressed ER-stress-induced apoptosis and cell death in 8-shogaol-treated AGS and NCI-N87 cell lines. 8-Shogaol-induced NADPH oxidase 4 (NOX4) activation is related to ROS generation. However, NOX4 knockdown and ROS inhibitors DPI or NAC blocked ER-stress-induced apoptosis by suppressing the inhibition of cell viability and the enhance of caspase-3 activity, intracellular ROS activity, and cytotoxicity LDH in 8-shogaol-treated AGS and NCI-N87 cell lines. Radioresistant gastric cancer models (AGSR and NCI-N87R) were developed and combined with 8-shogaol and radiation (2 Gy) to overcome radioresistance via the upregulation of N-cadherin and vimentin and the downregulation of E-cadherin. Therefore, these results indicated that 8-shogaol is a novel combined therapeutic strategy in gastric cancer radiotherapy. Full article
