Abstract
BACKGROUND & AIMS We evaluated the efficacy of herbal combination of curcumin-QingDai (CurQD) in active ulcerative colitis (UC). METHODS Part I was an open-label trial of CurQD in patients with active UC, defined by a Simple Clinical Colitis Activity Index score of 5 or higher and a Mayo endoscopic subscore of 2 or higher. Part II was a placebo-controlled trial conducted in Israel and Greece, randomizing active UC patients at a 2:1 ratio to enteric-coated CurQD 3 g/d or placebo for 8 weeks. The co-primary outcome was clinical response (reduction in the Simple Clinical Colitis Activity Index of ≥3 points) and an objective response (Mayo endoscopic subscore improvement of ≥1 or a 50% fecal calprotectin reduction). Responding patients continued either maintenance curcumin or placebo alone for an additional 8 weeks. Aryl-hydrocarbon receptor activation was assessed by cytochrome P450 1A1 (CYP1A1) mucosal expression. RESULTS In part I, 7 of 10 patients responded and 3 of 10 achieved clinical remission. Of 42 patients in part II, the week 8 co-primary outcome was achieved in 43% and 8% of CurQD and placebo patients, respectively (P = .033). Clinical response was observed in 85.7% vs 30.7% (P < .001), clinical remission in 14 of 28 (50%) vs 1 of 13 (8%; P = .01), a 50% calprotectin reduction in 46.4% vs 15.4% (P = .08), and endoscopic improvement in 75% vs 20% (P = .036) in the CurQD and placebo groups, respectively. Adverse events were comparable between groups. By week 16, curcumin-maintained clinical response, clinical remission, and clinical biomarker response rates were 93%, 80%, and 40%, respectively. CurQD uniquely up-regulated mucosal CYP1A1 expression, which was not observed among patients receiving placebo, mesalamine, or biologics. CONCLUSIONS In this placebo-controlled trial, CurQD was effective for inducing response and remission in active UC patients. The aryl-hydrocarbon receptor pathway may merit further study as a potential UC treatment target. CLINICALTRIALS gov ID: NCT03720002.

Mater Today Bio 2023; 22:100756. [PMID: 37593218 PMCID: PMC10430593 DOI: 10.1016/j.mtbio.2023.100756] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2023] [Revised: 07/10/2023] [Accepted: 07/30/2023] [Indexed: 08/19/2023] Open
Abstract
Indigo naturalis (IN) has been extensively used as a topical treatment for psoriasis. However, clinical applications of IN in ointment were hampered by its limited transdermal efficiency and dark stains. To address the aforementioned issues, nanopatches carrying IN were fabricated using poly(ε-caprolactone, PCL)/poly(ethylene oxide, PEO) and topically applied to psoriasiform skin. The ideal ratio of 5% PCL/PEO was established to be 80:20 (w/w), and 15% IN as payload was confirmed. Investigations on the three principal active components of IN release indicated that indirubin and tryptanthrin were released in bursts, while indigo was released in a limited and controlled manner. Further biological analyses confirmed a favorable biocompatibility of amphiphilic IN-PCL/PEO, which coincided with the intended therapeutic outcomes as measured by severity index scoring and pathological evaluations in vivo. The advantages of IN as nanopatches over ointment could be due to improved transdermal distribution of indirubin and tryptanthrin, resulting in effective management of epidermal hyperplasia and blood vessel remodeling. Meanwhile, due to the lower preservation of epidermal indigo, IN-PCL/PEO nanopatches caused no skin coloration. Similarly, during a 4-week topical treatment of IN-PCL/PEO nanopatches, the safety and anti-psoriatic benefits were obtained in an initial human test. The conversion of IN from topical cream to electrospun nanofibers opens up new avenues for bench-to-bedside translation of this herbal therapy and provides mechanistic insight into IN's roles in the management of psoriasis.

Abstract
There is a lack of efficacious topical treatments for patients suffering from psoriatic nail disease (PND). We investigated the efficacy of Calcipotriol-Betamethasone Dipropionate (Cal/BD) foam with and without ablative fractional laser (AFL) in patients with PND. A total of 144 nails from 11 patients were treated in a 24-week long, open-label, randomized, intra-patient controlled proof-of-concept hybrid trial. In addition to daily Cal/BD foam application, half of each patient's psoriatic nails were randomized to receive optical coherence tomography (OCT)-guided AFL treatment at baseline, 6-, and 12-week follow-ups. In-clinic assessment (N-NAIL), patient-reported outcomes (PROMs), and drug consumption were supplemented by remote evaluation of 15 subclinical OCT features, smartphone app-based safety monitoring, and photo-based assessment (NAPSI). After 24 weeks of Cal/BD foam treatment, patients achieved a significant improvement (p < 0.001) in both clinical (N-NAIL -76%, NAPSI -68%) and subclinical (OCT -43%) PND severity as well as a 71% reduction in PROMs. AFL-assisted Cal/BD treatment led to higher clinical (N-NAIL -85%, NAPSI -78%) and OCT-assessed (-46%) reduction of PND signs than Cal/BD alone (N-NAIL -66%, NAPSI -58%, OCT -37%), but did not reach statistical significance. Smartphone app images documented adverse events and mild local skin reactions, particularly erythema (75%), laser-induced swelling (28%), and crusting (27%). This hybrid trial demonstrated a reduction in clinical NAPSI and N-NAIL scores, subclinical OCT features, and PROMs, suggesting that Cal/BD foam is a safe and efficacious treatment for PND. Larger trials are warranted to prove the clinical benefit of AFL pretreatment as a Cal/BD delivery enhancer.

Abstract
The nail is a specialized keratinous skin appendage that is often overlooked, even though nail disorders comprise approximately 10% of all dermatologic conditions. We provide an overview on the basic anatomy of the nail and function of each structure. We examine the chemical profile, including the keratin and mineral composition, of the nail plate. Subsequently, nail manifestations are reviewed, as virtually every nutritional deficiency can affect nail growth in some manner. We focus on how each nutritional deficiency can affect the different anatomic structures of the nail unit. The terminology and the differential diagnoses of the many different nail plate and nail bed abnormalities are reviewed. Finally, we focus on the evidence behind nutrition-based treatments in the setting of several nail disorders.

Abstract
Nail psoriasis is a refractory disease that affects 50-79% skin psoriasis patients and up to 80% of patients with psoriatic arthritis (PsA). The pathogenesis of nail psoriasis is still not fully illuminated, although some peculiar inflammatory cytokines and chemokines seems to be the same as described in psoriatic skin lesions. Psoriatic nail involving matrix can cause pitting, leukonychia, red spots in lunula, and nail plate crumbling, while nail bed involvement can result in onycholysis, oil-drop discoloration, nail bed hyperkeratosis, and splinter hemorrhages. The common assessment methods of evaluating nail psoriasis includes Nail Psoriasis Severity Index (NAPSI), Nail Assessment in Psoriasis and Psoriatic Arthritis (NAPPA), Nail Psoriasis Quality of life 10 (NPQ10), and so on. Treatment of nail psoriasis should be individualized according to the number of involving nail, the affected site of nail and presence of skin and/or joint involvement. Generally, topical therapies are used for mild nail psoriasis, while biologic agents such as etanercept are considered for severe nail disease and refractory nail psoriasis. Even though the current literature has shown some support for the pathogenesis, clinical presentation, or therapies of nail psoriasis, systemic review of this multifaceted disease is still rare to date. We elaborate recent developments in nail psoriasis epidemiology, pathogenesis, anatomy, clinical manifestation, diagnosis, differential diagnosis, and therapies to raise better awareness of the complexity of nail psoriasis and the need for early diagnosis or intervention.

Antileukemic effects of indigo naturalis constituents by "target constituent knock-out" coupled with semipreparative liquid chromatography and quadrupole time-of-flight mass spectrometry. Biomed Chromatogr 2021; 35:e5216. [PMID: 34254701 DOI: 10.1002/bmc.5216] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/12/2020] [Revised: 07/07/2021] [Accepted: 07/09/2021] [Indexed: 11/06/2022]
Abstract
A novel approach is presented to identify constituents with antileukemic properties in extracts of Indigo naturalis (Qingdai in Chinese). Target compounds (A+ , BC+ , and ABC+ ) that knocked out specific constituents displayed antileukemic effects in a total extract of I. naturalis and negative constituents (A- , BC- , and ABC- ) that knocked out target compounds were separated, identified and knocked out by semipreparative liquid chromatography (semipreparative HPLC) and quadrupole time-of-flight mass spectrometer. Quantitative methods were used to evaluate the content of each knocked-out constituent in the total extract (D). Subsequently, interactions between the antileukemic effects of knocked-out constituents and D were screened and evaluated at the cellular level. Negative constituents including A- (65.47% ± 1.20%), BC- (54.61% ± 2.43%) and ABC- (67.49% ± 3.28%) displayed a greater inhibitory effect than D (47.16% ± 0.072%), which was not knocked out after 24 h of incubation, whereas the target compounds had not superior. Target compounds may have caused an antagonistic effect on the corresponding negative constituents. After 48 h, inhibition of proliferation by D (75.48% ± 3.78%) increased compared with that by negative constituents, whereas the antagonistic effect of target components on negative constituents was diminished. This result may reflect competitive antagonism. Comparing the reactions after 24 and 48 h, the inhibitory ratio of ABC- (79.29% ± 1.22%) in these knocked-out constituents and D was always the highest. With different concentrations tested after 48 h, ABC- significantly increased the rate of apoptosis on K562 cells (P < 0.01), indicating that in addition to indirubin, tryptanthrin and isorhamnetin, other antileukemic constituents may be present. Our study presents an approach that is a truer reflection of the antileukemic effects of knocked-out constituents in I. naturalis supported by reference to pharmacodynamic actions and the quality of I. naturalis. The approach may be useful for the analysis of other herbal extracts found in traditional Chinese medicine.

Abstract
Nail psoriasis has a prevalence that ranges from 10 to 82% and can significantly impact the quality of life of patients. Nail psoriasis is one of the most challenging areas to treat, and multiple therapies have been explored. Topical and injectable therapies are recommended for few-nail disease. Systemic therapies, including biologics, can be considered for patients with multiple and resistant nail disease, impaired quality of life, and severe skin and joint involvement, due to their long-term efficacy. Although outcome data are difficult to compare, interleukin (IL)-17 inhibitors may have superior short-term efficacy when compared to IL-23 inhibitors and tumor necrosis factor (TNF)-alpha inhibitors, although long-term efficacy is similar to TNF-alpha inhibitors. IL-23 inhibitors and TNF-alpha inhibitors have a similar efficacy for nail psoriasis.

Abstract
BACKGROUND As one of the oldest traditional dyes, people worldwide have used natural indigo for centuries. Local people have unique knowledge about indigo identification, which is crucial for indigo quality control and determining the dyeing effects. However, such traditional knowledge is rarely documented and explained. Therefore, the aims of this study were to document and assess the traditional knowledge used by local people when identifying natural indigo paste as well as quantitatively explore the characteristics and material basis of such traditional knowledge. METHOD Three field surveys were conducted between 2019 and 2020. A total of 283 traditional indigo-paste artisans were interviewed in Guizhou, Yunnan, and Fujian Provinces. The frequency of citation, mention index, and fidelity level of each indigo-paste quality criterion were calculated to determine the most commonly used, recognized, and important quality criteria. To explore the characteristics and material basis of the traditional knowledge, we analyzed 21 indigo-paste samples using high-performance liquid chromatography with diode-array detection (HPLC-DAD), pH, and particle size analyses. RESULTS Local people possess unique knowledge to identify natural indigo. Based on this knowledge accumulated over thousands of years, four criteria (color, taste, touch, and dyeing ability) were chosen by local people, and using these criteria, nature indigo was divided into five quality grades. The best quality indigo paste was judged according to the following folk criteria: dark blue in color with a purple-red luster; smooth and difficult to wipe off; having a sweet, bitter or spicy taste; and easy cloth dyeing. Additionally, the higher the contents of indigo and indirubin-especially indirubin-the better is the quality of the indigo paste. Within the pH range of 9-12, high-quality indigo-paste was more acidic. There was no significant relationship between particle size and quality. CONCLUSION The ancient methods used by local people for identifying natural indigo are comprehensive and unique. By documenting the various folk quality criteria and conducting quantitative analyses, this study revealed the importance of indirubin and pH for assessing the quality of indigo paste. These findings differ from existing quality standards for synthetic indigo. Amid rapid modernization, traditional knowledge remains invaluable as a world heritage of humanity that warrants preservation.

Chinese Herbal Medicines (CHM) are the most common interventions of traditional Chinese medicine (TCM), typically administered as either single herbs or formulas. Systematic reviews (SRs) are essential references for evaluating the efficacy and safety of CHM treatments accurately and reliably. Unfortunately, the reporting quality of SRs with CHM is not optimal, especially the reporting of CHM interventions and the rationale of why these interventions were selected. To address this problem, a group of TCM clinical experts, methodologists, epidemiologists, and editors has developed a PRISMA extension for CHM interventions (PRISMA-CHM) through a comprehensive process, including registration, literature review, consensus meeting, three-round Delphi survey, and finalization. The PRISMA checklist was extended by introducing the concept of TCM Pattern and the characteristics of CHM interventions. A total of twenty-four items (including sub-items) are included in the checklist, relating to title (1), structured summary (2), rationale (3), objectives (4), eligibility criteria (6), data items (11), synthesis of results (14, 21), additional analyses (16, 23), study characteristics (18), summary of evidence (24), and conclusions (26). Illustrative examples and explanations are also provided. The group hopes that PRISMA-CHM 2020 will improve the reporting quality of SRs of CHM.

JOURNAL OF ETHNOPHARMACOLOGY 2020; 250:112477. [PMID: 31838180 DOI: 10.1016/j.jep.2019.112477] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/19/2019] [Revised: 11/26/2019] [Accepted: 12/10/2019] [Indexed: 06/10/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Indigo naturalis, a herbal medicine with a history of use dating back to ancient times, may be a good alternative topical treatment for atopic dermatitis (AD). AIM OF THE STUDY To provide empirical evidence of the efficacy and safety of Indigo naturalis ointment in treating AD. MATERIALS AND METHODS In this randomized double-blind clinical trial, participants aged 6 to 65 years with AD affecting less than 40% of their body surface area (BSA) and an Investigator's Global Assessment (IGA) score of 2 to 4 were randomized (2:1) to receive either Lindioil ointment or a vehicle ointment twice daily for 6 weeks. The primary endpoint was the percentage change in the Eczema Area Severity Index (EASI) from baseline to week 6. Secondary endpoints were as follows: EASI improvement ≥50%, 75%, and 90%; IGA score; BSA affected by AD; pruritus severity; and Dermatology Life Quality Index. The safety assessment included adverse events (AEs), laboratory tests, and physical examinations. RESULTS The Lindioil group (32 participants) and vehicle group (16 participants) achieved mean percentage EASI reductions of 49.9% ± 36.5% (95% CI 36.8%-63.1%) and 19.6% ± 52.2% (95% CI -8.2%-47.4%), respectively (P = 0.0235). The Lindioil group also showed greater improvement in every secondary assessment category. No significant AEs occurred. CONCLUSION Indigo naturalis ointment is effective for treating mild to severe AD topically, and appears to be safe. This is the first clinical trial to provide evidence supporting topical indigo-based AD treatment. ClinicalTrials.gov identifier: NCT02669888.

Abstract
Importance Up to 51% of patients with psoriasis report the use of complementary and alternative medicine (CAM) in their treatment regimen, although it is unclear which CAM therapies are effective for treatment of psoriasis. Objective This review compiles the evidence on the efficacy of the most studied CAM modalities for treatment of patients with plaque psoriasis and discusses those therapies with the most robust available evidence. Evidence Review PubMed, Embase, and ClinicalTrials.gov searches (1950-2017) were used to identify all documented CAM psoriasis interventions in the literature. The criteria were further refined to focus on those treatments identified in the first step that had the highest level of evidence for plaque psoriasis with more than 1 randomized clinical trial supporting their use. This excluded therapies lacking randomized clinical trial (RCT) data or showing consistent inefficacy. Findings Primary CAM therapy searches identified 457 articles, of which 107 articles were retrieved for closer examination. Of those articles, 54 were excluded because the CAM therapy did not have more than 1 RCT on the subject or showed consistent lack of efficacy. An additional 7 articles were found using references of the included studies, resulting in a total of 44 RCTs (17 double-blind, 13 single-blind, and 14 nonblind), 10 uncontrolled trials, 2 open-label nonrandomized controlled trials, 1 prospective controlled trial, and 3 meta-analyses. Compared with placebo, application of topical indigo naturalis, studied in 5 RCTs with 215 participants, showed significant improvements in the treatment of psoriasis. Treatment with curcumin, examined in 3 RCTs (with a total of 118 participants), 1 nonrandomized controlled study, and 1 uncontrolled study, conferred statistically and clinically significant improvements in psoriasis plaques. Fish oil treatment was evaluated in 20 studies (12 RCTs, 1 open-label nonrandomized controlled trial, and 7 uncontrolled studies); most of the RCTs showed no significant improvement in psoriasis, whereas most of the uncontrolled studies showed benefit when fish oil was used daily. Meditation and guided imagery therapies were studied in 3 single-blind RCTs (with a total of 112 patients) and showed modest efficacy in treatment of psoriasis. One meta-analysis of 13 RCTs examined the association of acupuncture with improvement in psoriasis and showed significant improvement with acupuncture compared with placebo. Conclusions and Relevance The CAM therapies with the most robust evidence of efficacy for treatment of psoriasis are indigo naturalis, curcumin, dietary modification, fish oil, meditation, and acupuncture. This review will aid practitioners in advising patients seeking unconventional approaches for treatment of psoriasis.

Abstract
Proteins play crucial and diverse roles within the cell. To exert their biological function they must fold to acquire an appropriate three-dimensional conformation. Once their function is fulfilled, they need to be properly degraded to hamper any possible damage. Protein homeostasis or proteostasis comprises a complex interconnected network that regulates different steps of the protein quality control, from synthesis and folding, to degradation. Due to the primary role of proteins in cellular function, the integrity of this network is critical to assure functionality and health across lifespan. Proteostasis failure has been reported in the context of aging and neurodegeneration, such as Alzheimer’s and Parkinson’s disease. Therefore, targeting the proteostasis elements emerges as a promising neuroprotective therapeutic approach to prevent or ameliorate the progression of these disorders. A variety of natural products are known to be neuroprotective by protein homeostasis interaction. In this review, we will focus on the current knowledge regarding the use of natural products as modulators of different components of the proteostasis machinery within the framework of age-associated neurodegenerative diseases.

Abstract
Plant-derived microRNAs have recently been reported to function in human blood and tissues. Controversy was immediately raised due to possible contamination and the lack of large sample sizes. Here, we report thousands of unique small RNAs derived from traditional Chinese medicine (TCM) herbs found in human blood cells and mouse lung tissues using a large-scale analysis. We extracted small RNAs from decoctions of 10 TCM plants (Ban Zhi Lian, Chai Hu, Chuan Xin Lian, Di Ding Zi Jin, Huang Qin, Jin Yin Hua, Lian Qiao, Pu Gong Ying, Xia Ku Cao, and Yu Xing Cao) and obtained millions of RNA sequences from each herb. We also obtained RNA-Seq data from the blood cells of humans who consumed herbal decoctions and from the lung tissues of mice administered RNAs from herbal decoctions via oral gavage. We identified thousands of unique small RNA sequences in human blood cells and mouse lung tissues. Some of these identified small RNAs from Chuan Xin Lian and Hong Jing Tian could be mapped to the genomes of the herbs, confirming their TCM plant origin. Small RNAs derived from herbs regulate mammalian gene expression in a sequence-specific manner, and thus are a superior novel class of herbal drug components that hold great potential as oral gene-targeted therapeutics, highlighting the important role of herbgenomics in their development.

Abstract
Nail psoriasis (NP) and nail lichen planus (NLP) can be limiting, stigmatizing and difficult to treat. Dermatologists commonly treat psoriasis and lichen planus but when associated onychodystrophy is present or is an isolated finding, some develop apprehension. The goal of this review is to develop therapeutic ladders to be used as a guide for the management of NP and NLP in everyday clinical practice. Evidence-based therapies for NP are robust and range from topical treatments to conventional systemic therapies (i.e., methotrexate, cyclosporine), new oral agents (i.e., apremilast and tofacitinib), and biologics. The literature for treatment of NLP is severely limited, with therapy mainly consisting of topical, intralesional, or systemic corticosteroids or methotrexate.

Abstract
Baphicacanthus cusia (Nees) Bremek is an herb widely used for the clinical treatment of colds, fever, and influenza in Traditional Chinese Medicine. The roots, stems and leaves can be used as natural medicine, in which indigo and indirubin are two main active ingredients. In this study, quantification of indigo, indirubin, indican and adenosine among various tissues of B. cusia was conducted using HPLC-DAD. Leaves have significantly higher contents than stems and roots (380.66, 315.15, 20,978.26, 4323.15 μg/g in leaves, 306.36, 71.71, 3,056.78, 139.45 μg/g in stems, and 9.31, 7.82, 170.45, 197.48 μg/g in roots, respectively). De novo transcriptome sequencing of B. cusia was performed for the first time. The sequencing yielded 137,216,248, 122,837,394 and 140,240,688 clean reads from leaves, stems and roots respectively, which were assembled into 51,381 unique sequences. A total of 33,317 unigenes could be annotated using the databases of Nr, Swiss-Prot, KEGG and KOG. These analyses provided a detailed view of the enzymes involved in indican backbone biosynthesis, such as cytochrome P450, UDP-glycosyltransferase, glucosidase and tryptophan synthase. Analysis results showed that tryptophan synthase was the candidate gene involved in the tissue-specific biosynthesis of indican. We also detected sixteen types of simple sequence repeats in RNA-Seq data for use in future molecular mark assisted breeding studies. The results will be helpful in further analysis of B. cusia functional genomics, especially in increasing biosynthesis of indican through biotechnological approaches and metabolic regulation.

Abstract
BACKGROUND Harmonization of outcome measures is needed to increase the value of clinical trials on nail psoriasis. OBJECTIVES To provide the first step in core outcome set (COS) development for nail psoriasis. METHODS A systematic review was performed to identify outcome instruments and corresponding outcome domains used in (ongoing) randomized controlled trials. RESULTS Identified outcome domains included clinical signs, quality of life, symptoms and delivery of care. The Nail Psoriasis Severity Index (NAPSI) was the most commonly used measure to assess clinical signs (74% of studies). Other outcome instruments used included the Nail Area Severity score, composite fingernail score, a Physician's Global Assessment, individual nail features or a combination of these. Heterogeneity in type and reporting (e.g. NAPSI 50, NAPSI 75) of outcome instruments was high and characteristics were often insufficiently reported. In total 43% of studies assessed quality of life, with 3% of studies using a nail psoriasis-specific tool. Assessment of symptoms and delivery of care was limited. CONCLUSIONS Heterogeneity in the type and reporting of nail psoriasis outcome instruments needs to be addressed in the process towards COS development. Sufficient reporting of instrument characteristics should be encouraged. As nail psoriasis is generally assessed secondarily to psoriasis of the skin or joints, collaboration between different research groups in COS development is needed.

Abstract
Psoriasis is the skin disease that most frequently affects the nails. Depending on the very nail structure involved, different clinical nail alterations can be observed. Irritation of the apical matrix results in psoriatic pits, mid-matrix involvement may cause leukonychia, whole matrix affection may lead to red lunulae or severe nail dystrophy, nail bed involvement may cause salmon spots, subungual hyperkeratosis, and splinter hemorrhages, and psoriasis of the distal nail bed and hyponychium causes onycholysis whereas that of the proximal nail fold causes psoriatic paronychia. The more extensive the involvement, the more severe is the nail destruction. Pustular psoriasis may be seen as yellow spots under the nail or, in case of acrodermatitis continua suppurativa, as an insidious progressive loss of the nail organ. Nail psoriasis has a severe impact on quality of life and may interfere with professional and other activities. Management includes patient counseling, avoidance of stress and strain to the nail apparatus, and different types of treatment. Topical therapy may be tried but is rarely sufficiently efficient. Perilesional injections with corticosteroids and methotrexate are often beneficial but may be painful and cannot be applied to many nails. All systemic treatments clearing widespread skin lesions usually also clear the nail lesions. Recently, biologicals were introduced into nail psoriasis treatment and found to be very effective. However, their use is restricted to severe cases due to high cost and potential systemic adverse effects.

Abstract
BACKGROUND Patients with psoriasis often enquire about the use of numerous botanical therapeutics. It is important for dermatologists to be aware of the current evidence regarding these agents. METHODS We conducted a systematic literature search using the PubMed, MEDLINE, and EMBASE databases for controlled and uncontrolled clinical trials that assessed the use of topical botanical therapeutics for psoriasis. The search included the following keywords: 'psoriasis' and 'plant' or 'herbal' or 'botanical'. We also reviewed citations within articles to identify additional relevant sources. We then further refined the results by route of administration and the topical botanical agents are reviewed herein. RESULTS A total of 27 controlled and uncontrolled clinical trials addressing the use of topical botanical agents for psoriasis were assessed in this review. We found that the most highly studied and most efficacious topical botanical therapeutics were Mahonia aquifolium, indigo naturalis, aloe vera, and, to a lesser degree, capsaicin. The most commonly reported adverse effects were local skin irritation, erythema, pruritus, burning, and pain. However, the overall evidence for these therapeutics remains limited in quantity and quality. CONCLUSION The literature addresses a large number of studies in regard to botanicals for the treatment of psoriasis. While most agents appear to be safe, further research is necessary before topical botanical agents can be consistently recommended to patients.

Abstract
Nail involvement affects 80-90 % of patients with plaque psoriasis, and is even more prevalent in patients with psoriatic arthritis. This review is the result of a systemic approach to the literature and covers topical, intralesional, conventional systemic, and biologic systemic treatments, as well as non-pharmacological treatment options for nail psoriasis. The available evidence suggests that all anti-tumor necrosis factor-α, anti-interleukin (IL)-17, and anti-IL-12/23 antibodies which are available for plaque psoriasis and psoriatic arthritis are highly effective treatments for nail psoriasis. Conventional systemic treatments, including methotrexate, cyclosporine, acitretin, and apremilast, as well as intralesional corticosteroids, can also be effective treatments for nail psoriasis. Topical treatments, including corticosteroids, calcipotriol, tacrolimus, and tazarotene, have also been shown to have a position in the treatment of nail psoriasis, particularly in mild cases. Finally, non-pharmacological treatment options, including phototherapy, photodynamic therapy, laser therapy, and several radiotherapeutic options, are also reviewed but cannot be advised as first-line treatment options. Another conclusion of this review is that the lack of a reliable core set of outcomes measures for trials in nail psoriasis hinders the interpretation of results, and is urgently needed.
