Introduction: Epidermolysis bullosa (EB) is a rare inherited genetic skin disorder with severe skin itching and recurrent blisters and erosion. There is no effective and specific therapy for all types of EB. Objective: The aim of this study was to evaluate a topical formulation of henna (Lawsonia inermis L.) in the management of wounds and the itching sensation in patients with EB. Methods: This is a pilot single-arm clinical trial. Nine patients with recessive dystrophic EB (RDEB), with the age range of 5 to 32 years old were enrolled in the study. The patients were instructed to apply the topical 1% henna ointment once daily on two erosions and on also two sites with moderate to a severe itching sensation. The total duration of the intervention was four weeks with weekly follow-up visits. Patient global impression of improvement (PGI-I), visual analog scale (VAS), and clinical global impression of improvement (CGI-I) were used for assessing the wound healing process and itching discomfort. Results: There was a significant improvement in the skin symptoms of epidermolysis bullosa including skin redness, itching, burning, and local warmness (p-value

Henna is a commonly used traditional cosmetic agent, which also holds medical potentials and is used to treat skin lesions including seborrheic dermatitis or fungal infections and also has possible anti-inflammatory effects. It contains lawsone (2-hydroxy-1,4-naphthoquinone) and, therefore, has the potential to induce oxidative hemolysis. Henna-induced hemolysis has been previously reported in children with Glucose 6-Phosphate Dehydrogenase Deficiency. Here, we report an 85-year-old man who developed hemolytic anemia and acute kidney injury following oral consumption of henna to help his dyspnea. He was treated with hydration, bicarbonate, and dexamethasone. Over the course of hospitalization, the patient developed ventilator-associated pneumonia and was treated with antibiotic. He was discharged after one month. This finding is of high importance due to common use of henna, especially among people with false beliefs regarding traditional and herbal medicine, and highlights the role of a full history taking.

Background: Episiotomy is one of the most common surgical interventions performed to facilitate delivery. Anti-inflammatory and antibacterial effects of Persian oak (Quercuspersica) and henna (Lawsonia inermis) have been proved in previous studies. The aim of this study is to evaluate the effect of Q. persica and L. inermis ointment on episiotomy wound healing in primiparous women and comparing it with placebo group. Materials and Methods: This was a double-blind clinical trial conducted on 160 primiparous women who underwent episiotomy. The cases were randomly selected and divided into four groups of forty patients including control, placebo, those who consume topical henna, and those who consume topical Persian oak ointment. Pain and recovery assessment was done at baseline and 7th, 10th, and 14th days after birth and measured by Redness, Edema, Ecchymosis, Discharge, and Approximation (REEDA scale) and patients' pain intensity was also measured by a visual analog scale (VAS). The collected data were analyzed using Chi-square test, one-way ANOVA, and repeated measures ANOVA test by SPSS (version 22). Results: The results revealed that according to the reduced score of REEDA till the 14th day after the delivery, the wound healing in the henna group and the oak group (-2.58 ± 0.29 and - 2.04 ± 0.31, respectively) was higher than the control and placebo groups (-1.62 ± 0.34 and - 1.95 ± 0.32, respectively) (P < 0.05). Furthermore, on the 14th day, the mean VAS score was not significantly different between henna and oak groups (henna group: 2.58 ± 0.25 and oak group: 2.23 ± 0.18); however, both intervention groups had a significant difference with the placebo and control groups (P < 0.05). Conclusion: The findings showed that the use of henna and oak ointment improves episiotomy wound healing process, so it is recommended for primiparous women. [ABSTRACT FROM AUTHOR]

The bio-reduction of azo dyes is significantly dependent on the availability of electron donors and external redox mediators. In this study, the natural henna plant biomass was supplemented to promote the biological reduction of an azo dye of Acid Orange 7 (AO7). Besides, the machine learning (ML) approach was applied to decipher the intricate process of henna-assisted azo dye removal. The experimental results indicated that the hydrolysis and fermentation of henna plant biomass provided both electron donors such as volatile fatty acid (VFA) and redox mediator of lawsone to drive the bio-reduction of AO7 to sulfanilic acid (SA). The high henna dosage selectively enriched certain bacteria, such as Firmicutes phylum, Levilinea and Paludibacter genera, functioning in both the henna fermentation and AO7 reduction processes simultaneously. Among the three tested ML algorithms, eXtreme Gradient Boosting (XGBoost) presented exceptional accuracy and generalization ability in predicting the effluent AO7 concentrations with pH, oxidation-reduction potential (ORP), soluble chemical oxygen demand (SCOD), VFA, lawsone, henna dosage, and cumulative henna as input variables. The validating experiments with tailored optimal operating conditions and henna dosage (pH 7.5, henna dosage of 2 g/L, and cumulative henna of 14 g/L) confirmed that XGBoost was an effective ML model to predict the efficient AO7 removal (91.6%), with a negligible calculating error of 3.95%. Overall, henna plant biomass addition was a cost-effective and robust method to improve the bio-reduction of AO7, which had been demonstrated by long-term operation, ML modeling, and experimental validation., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.

New and creative methodologies for the fabrication of silver nanoparticles (Ag-NPs), which are exploited in a wide range of consumer items, are of significant interest. Hence, this research emphasizes the biological approach of Ag-NPs through Egyptian henna leaves (Lawsonia inermis Linn.) extracts and analysis of the prepared Ag-NPs. Plant extract components were identified by gas chromatography mass spectrometry (GC-mass). The analyses of prepared Ag-NPs were carried out through UV-visible (UV-Vis), X-ray diffraction (XRD), transmission electron microscope (TEM), scanning electron microscope (SEM), and Fourier transform infrared (FTIR) analysis. UV-Vis reveals that Ag-NPs have a maximum peak at 460 nm in visible light. Structural characterization recorded peaks that corresponded to Bragg's diffractions for silver nano-crystal, with average crystallite sizes varying from 28 to 60 nm. Antibacterial activities of Ag-NPs were examined, and it is observed that all microorganisms are very sensitive to biologically synthesized Ag-NPs., (© 2023. The Author(s).)

Background: Detecting pressure ulcer is an important nursing diagnostic and care requirement in patients hospitalized in Intensive Care Unit (ICU). The purpose of this study is to examine the effect of Lawsonia plant on pressure ulcer grade one in ICU patients. Methods: In this clinical trial, 72 patients eligible for hospitalization in hospitals of Isfahan University of Medical Sciences were divided randomly into two control and intervention groups. The standard program of skin care was implemented on both groups; in addition, a mixture of Lawsonia (henna) and distilled water was applied topically in the intervention group. The classification form of the International Pressure Ulcer Advisory Panel was used to identify grade one ulcers. Data were collected on the 1st day through demographic information questionnaire and Braden pressure ulcer risk assessment scale. An infrared thermometer was used to record local temperature of the ulcers on a daily basis. Assessments were made based on Pressure Ulcer Scale for Healing (PUSH), and the pressure ulcer area was examined per square centimeter on the 1st, 4th, and 7th days. The data were analyzed using SPSS 16. Results: The average change in the ulcer area per square centimeter in the control group increased by 29.9 ± 37.93 whereas it decreased by 3.54 ± 33.91 in the intervention group. The mean PUSH score decreased in the intervention group (5.36 ± 3.12) while it increased in the control group (1.91 ± 1.53). The average changes of PUSH score before and after the intervention showed a significant difference in both groups. Conclusions: With regard to the effect of henna on the reduction of ulcer area and the average PUSH score in ICU patients, the application of henna is recommended for healing grade one pressure ulcers.

Evaluation of the in vitro antibacterial activity of Methanol extracts isolated from Henna (Lawsonia inermis) leaf against two food born infection causing pathogens, gram-positive Staphylococcus aureus and gram-negative Klebsiella pneumoniae. This interventional study was carried out in the Department of Pharmacology and Therapeutics in collaboration with the Department of Microbiology, Mymensingh Medical College, Bangladesh from January 2021 to December 2021. The antibacterial activity was tested at different concentrations of Methanol Henna leaf extracts by using disc diffusion and broth dilution method. The extract was prepared by using solvents Methanol and 0.1% dimethyl sulfoxide (DMSO). The test microorganisms were also tested for their activity against a standard antibiotic Ciprofloxacin by broth dilution method and the result was compared with that of Methanol extracts. Methanol Henna Extracts (MHE) were used initially in nine different concentrations (2.5, 5, 10, 20, 50, 100, 200, 500 and 1000mg/ml) and later in selected concentrations as needed to confirm the more precise margin of antimicrobial sensitivity of the extracts. Among different concentrations of the MHE, 100mg/ml and above concentrations showed inhibitory effect against afore said bacteria. The MIC for Staphylococcus aureus and Klebsiella pneumoniae were 100mg/ml in MHE. The MIC of Ciprofloxacin was 1μg/ml against Staphylococcus aureus and 1.5μg/ml for Klebsiella pneumoniae. The MIC of Ciprofloxacin was the lowest in comparison to MICs of MHE for the test organisms. This study showed that Methanol Henna extracts demonstrated antibacterial effects against pathogens. From this study, it is clearly observed that there is definite antibacterial effect of the methanolic extract of Henna leaves (Lawsonia inermis) against Staphylococcus aureus and Klebsiella pneumoniae.

Introduction: Lawsonia Inermis (LI) is a shrub cultivated throughout India. Many in vitro studies have been done on antifungal activity of LI, although none of the studies have been conducted invivo. Aim: To evaluate the antifungal efficacy of ethanolic extract of crude lawsone in comparison with listerine mouth wash in known diabetics and wearing dentures. Materials and Methods: A total of 60 subjects were taken and randomly divided into two groups of 30 each. Group 1 received crude lawsone mouthwash and Group 2 received listerine mouth wash. Oral rinse technique was performed. Each subject was given distilled water at baseline and Colony Forming Units (CFU) of candidal species was determined. Post therapeutic samples were then collected 1hr and 1week following drug usage and they were further advised to use given mouth washes twice daily with volume of 5ml/rinse for 30 seconds and CFU was evaluated. Results: Crude lawsone mouthwash showed superior antifungal activity when compared to listerine mouthwash. On individual comparison of both mouth washes at baseline, 1hr and 1week highly significant results were obtained using inferential statistics. The inter group comparison was done using independent t-test where lawsone was considered to be more effective in reducing CFU, at 1hr and 1week of using the mouth wash (p

Wounds can be a result of surgery, an accident, or other factors. There is still a challenge to find effective topical wound-healing agents. This study aims to investigate the wound-healing activity of chemical and green synthesized chitosan nanoparticles (Ch-NPs) using Lawsonia inermis leaves extract. The nanoparticles were morphologically and chemically characterized using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and high-resolution transmission electron microscopy (HRTEM). Forty-five adult female albino rats were randomly divided into three groups. The cutaneous surgical wounds were topically treated with 0.9% normal saline (control group), green Ch-NPs (second group), and chemical Ch-NPs gels (third group), respectively. The clinical picture of wounds and histopathological changes were assessed on the 3rd, 7th, 14th, and 21st days post-treatment. X-ray diffraction analysis revealed great crystallinity and purity of nanoparticles. The studied nanoparticles increased the wound contraction percent (WC%), reduced healing time and wound surface area (WSA), and these results were backed up by histological findings that indicated improved epithelialization, dermal differentiation, collagen deposition, and angiogenesis in treated rats compared with control rats (p < 0.05). We concluded that the wound-healing effects of the studied nanoparticles are encouraging, and further studies for complete assessment are still needed., Competing Interests: Conflict of Interest The authors declare that they have no competing interest., (© The Author(s) 2023.

This study aimed to develop a new bioactive wound dressing based on electrospun poly (L-lactide-co-D, L-lactide) (PLDLLA) nanofibers containing Lawsonia inermis (LI) for burn wounds. The SEM results showed that loading LI increased the average diameter of PLDLLA nanofibers to 528 nm with smooth and beadless morphology. The analysis of LI release from PLDLLA nanofibers and film samples was measured by UV-vis spectrophotometry, and the obtained results revealed that LI molecules could diffuse from the nanofibrous sample with higher rate than film during 48 h. In this regard, the PLDLLA nanofibrous sample as a drug carrier has advantages compared to the film. Moreover, the antibacterial results confirmed the positive influence of LI related to the bacteria which in turn the growth inhibition zones were increased from 6 to 22 mm for P. aeruginosa , and from 3 to 16 mm for S. aureus while the LI concentration was set at 1.4% (w/v). Finally, animal model studies demonstrated that PLDLLA-LI nanofibers accelerated burn wound closure remarkably; thereby decreasing the wound area approximately 90% during the treatment period of 19 days. The histological observations dedicated that the appearance of the epithelial layer was increased dramatically alongside the thickness of around 40% for the wound treated with PLDLLA-LI nanofibrous sample rather than that without LI. Besides the epithelialization, it has been found that the wound covered by PLDLLA-LI wound dressing has condensed collagen fibers with no necrosis.

Body art by henna staining is a practice that is widely prevalent in the Middle East and Africa, and has been known to be in vogue for hundreds of years. The practice is also significant as a ceremonial custom for weddings and social gatherings. However, due to its natural components (Lawsone) and additives, including para-phenylene-diamine (PPD), henna has also been associated with a number of health hazards, including acute hemolysis and acute kidney injury (AKI). We report in this case, a female patient who presented with AKI and acute hemolytic anemia following excessive pre-wedding henna staining of her arms and legs., (Copyright © 2023 Copyright: © 2023 Saudi Journal of Kidney Diseases and Transplantation.)

Background: In conformity with the international trend to substitute the artificial agro-chemicals by natural products to improve growth and productivity of crops, there is a necessity to focus on the environment sustainable and eco-friendly resources to increase crops productivity per unit area. One of these resources is the use of biostimulants. The aim of this study is to allow the vertical expansion of wheat crop by improving its growth and productivity per unit area as well as enhancing its grain quality using henna leaf extract as a biostimulant., Results: Field study was conducted to evaluate the potentiality of different doses of henna leaf extract (HLE) for improving the performance of wheat plants (Triticum aestivum L.) at three development stages. Results revealed that the response was dose dependent hence both 0.5 and 1.0 g/L doses significantly enhanced the growth of shoot and root systems, biochemical traits, yield and yield related components with being 1.0 g/L the most effective one. Furthermore, 1.0 g/L HLE markedly enhanced the quality of the yielded grains as revealed by increasing the content of soluble sugars (23%), starch (19%), gluten (50%), soluble proteins (37%), amylase activity (27%), total phenolics, flavonoids and tannins (67, 87 and 23%, respectively) as well as some elements including Ca (184%), Na and Fe (10%). Also, HPLC analysis of grains revealed that 1.0 g/L dose significantly increased the level of different phytohormones, soluble sugars and flavonoids (quercetin, resveratrol and catechin)., Conclusion: Application of Henna (Lawsonia inermis) leaf extract at 1.0 g/L dose as a combination of seed priming and foliar spray can be recommended as a nonpolluting, inexpensive promising biostimulant, it can effectively enhance wheat growth, biochemical traits and productivity as well as improving the quality of the yielded grains., (© 2023.

Objectives: Radiotherapy is one of the treatments used for different types of cancer. Acute radiodermatitis is one of its most common complications. Despite the high prevalence of radiodermatitis, few studies investigated how to prevent or treat this complication. Hence, a standard treatment has not been introduced so far. We sought to evaluate the efficacy of Dermolina-Henna cream, a new polyherbal formulation, compared to Mometasone cream for alleviating acute radiodermatitis among breast cancer patients. Design: Randomized active-control double-blind clinical trial. Setting/Location: The oncology clinic of Shohaday-e Tajrish Hospital (Tehran, Iran). Subjects: Women older than 18 years with breast cancer undergoing radiotherapy. Interventions: Patients were instructed to apply a thin layer of Dermolina-Henna or Mometasone cream once daily on their lesions at least 3 h after radiotherapy for 4 weeks, and if grade I or II radiodermatitis developed, also afterward. Patients were visited weekly until end of study at after 4 weeks. Radiation Therapy Oncology Group standard questionnaires were evaluated and recorded every week as the primary outcome. Outcome measures: Primary outcome was defined as evaluating the efficacy of Dermolina-Henna cream to change the radiodermatitis grade, while the level of patients' satisfaction and the rate of adverse events recorded by patients were secondary outcomes. Results: The trends on decrease in number of lesions, erythema, radiodermatitis grade, burning sensation, pain, and itchiness were statistically significant for each treatment, separately ( p  < 0.001), except for radiodermatitis grade in Mometasone group ( p  = 0.4). Dermolina-Henna was significantly better than Mometasone in alleviating burning sensation ( p  < 0.001) and itchiness ( p  = 0.041). Approximately 3.7% of patients showed adverse events and 3.7% declared dissatisfaction in both groups. Conclusions: In summary, we showed that Dermolina-Henna cream and Mometasone cream were significantly effective in decreasing severity of radiodermatitis symptoms among patients with breast cancer. Dermolina-Henna cream was significantly superior to Mometasone cream in alleviating burning and itchiness. Clinical Trial Registration Number: IRCT20200115046144N1.

In modern medicine, some traditional remedies are introduced to be effective in treatment. Accordingly, the henna plant (Lawsonia inermis L.) is studied more than before. Previous studies have shown many medical properties for henna, such as anti-inflammatory and anti-fungal properties. Oral lichen planus (OLP) is a common mucocutaneous disease with chronic immunomodulatory disruptions. Topical corticosteroids are the first line of OLP treatment. Previous studies have suggested different adjunctive therapies for preventing the side effects of corticosteroids overuse. This study aimed to compare the effects of henna and chlorhexidine mouthwashes as adjunctive therapy. This parallel-group, double-blind, randomized controlled study was conducted on forty OLP patients. Luteolin content was determined in Henna mouthwash composed of 2% aqueous extract of henna, 2% ethanol, 10% glycerol, and 0.1% methylparaben distilled water. Henna or chlorhexidine mouthwashes were prescribed twice daily as an adjuvant to the topical corticosteroid treatment. Visual analog scale (VAS) index and Thongprasom rating were used to measure pain intensity and clinical signs of patients at days 0,7, and 14. The collected data were analyzed using SPSS software (version 26.0; SPSS). Ordinal logistic regression was used to investigate the effect of independent variables on Thongprasom and VAS scores. In this clinical trial, 82.6% of the participants were women. There was no difference between the two study groups in terms of VAS scores (p = 0.404) and clinical features (p = 0.305) in the second follow-up visit. All drug regimens caused clinical signs and symptoms relief. There was no significant difference between the groups receiving topical corticosteroid supplementation, neither henna mouthwash nor chlorhexidine mouthwash. The therapeutic effects of henna mouthwash in the main or adjuvant treatment of OLP need more evaluation in future research. Henna mouthwash can be a good alternative to chlorhexidine mouthwash if no side effects are reported. [Display omitted] [ABSTRACT FROM AUTHOR]

Objectives To describe the clinical presentation and case management of a dog that developed hemolytic anemia and evidence of renal tubular dysfunction after ingestion of a natural hair dye containing Lawsonia inermis (henna). To review cases of henna toxicity reported in the human literature. Case Summary An 8-year-old female spayed Border Collie was presented 5 days after ingestion of a box of natural hair dye. The dog was showing signs of lethargy, vomiting, diarrhea, and weakness. A serum biochemistry profile, complete blood count, and urinalysis demonstrated evidence of renal tubular dysfunction and a regenerative anemia without spherocytosis. The dog was treated with a transfusion of packed RBCs and IV fluids, resulting in significant clinical improvement. Repeat diagnostics showed resolution of the anemia and no lasting evidence of tubular dysfunction. New or Unique Information Provided To the authors' knowledge, this is the first reported case in the veterinary literature of toxicity following ingestion of Lawsonia inermis (henna). Henna ingestion was associated with the development of hemolytic anemia and acute kidney injury. [ABSTRACT FROM AUTHOR]

Developing biosynthesis of silver nanoparticles (Ag-NPs) using plant extract is an environmentally friendly method to reduce the use of harmful chemical substances. The green synthesis of Ag-NPs by Lawsonia inermis extract and its cellular toxicity and the antimicrobial effect was studied. The physical and chemical properties of synthesised Ag-NPs were investigated using UV-visible spectroscopy, infrared spectroscopy, X-ray diffraction (XRD), scanning, and transmission electron microscopy. The average size of Ag-NPs was 40 nm. The XRD result shows peaks at 2θ = 38.07°, 44.26°, 64.43°, and 77.35° are related to the FCC structure of Ag-NPs. Cytotoxicity of synthesised nanoparticles was evaluated by MTT toxicity test on breast cancer MCF7 cell line. Observations showed that the effect of cytotoxicity of nanoparticles on the studied cell line depended on concentration and time. The obtained IC 50 was considered for cells at a dose of 250 μg/ml. Growth and survival rates decreased exponentially with the dose. Antimicrobial properties of Ag-NPs synthesised with extract were investigated against Escherichia coli, Salmonella typhimurium, Bacillus cereus, and Staphylococcus aureus to calculate the minimum inhibitory concentration and the minimum bactericidal concentration of (MBC). The results showed that the synthesised Ag-NPs and the plant extract have antimicrobial properties. The lowest concentration of Ag-NPs that can inhibit the growth of bacterial strains was 25 μg/ml., (© 2022 Antibacterial Materials R&D Centre, Metal New materials Institute.

Introduction: Epidermolysis bullosa (EB) is a rare inherited genetic skin disorder with severe skin itching and recurrent blisters and erosion. There is no effective and specific therapy for all types of EB., Objectives: The aim of this study was to evaluate a topical formulation of henna (Lawsonia inermis Linnaeus) in the management of wounds and the itching sensation in patients with EB., Methods: This is a pilot single-arm clinical trial. Nine patients with recessive dystrophic EB, with the age range of 5 to 32 years were enrolled in the study. The patients were instructed to apply the topical 1% henna ointment once daily on two erosions and on also two sites with moderate to a severe itching sensation. The total duration of the intervention was 4 weeks with weekly follow-up visits. Patient global impression of improvement, visual analog scale, and clinical global impression of improvement were used for assessing the wound healing process and itching discomfort., Results: There was a significant improvement in the skin symptoms of epidermolysis bullosa including skin redness, itching, burning, and local warmness (P < 0.05). Local pain decreased during the study period, but this was not statistically significant (P < 0.19). One patient reported moderate xerosis of skin after continuous usage., Conclusions: It seems that the topical formulation of henna may be effective in the management of itching, burning, stringing, and cutaneous warmness sensation in patients with EB. Further controlled studies with larger sample sizes are recommended to better evaluate this formulation., Competing Interests: Competing interests: The authors declare that there is conflict of interest, in the way that two individuals listed in authors’ list, MMP and ZP, suffer from DEB and they participated in this clinical trial, but they did not have any role in response evaluation of the drug., (©2022 Niazi et al.)
