Abstract
The skin is an important organ that acts as a physical barrier to the outer environment. It is rich in immune cells such as keratinocytes, Langerhans cells, mast cells, and T cells, which provide the first line of defense mechanisms against numerous pathogens by activating both the innate and adaptive response. Cutaneous immunological processes may be stimulated or suppressed by numerous plant extracts via their immunomodulatory properties. Several plants are rich in bioactive molecules; many of these exert antimicrobial, antiviral, and antifungal effects. The present study describes the impact of plant extracts on the modulation of skin immunity, and their antimicrobial effects against selected skin invaders. Plant products remain valuable counterparts to modern pharmaceuticals and may be used to alleviate numerous skin disorders, including infected wounds, herpes, and tineas.

Abstract
The prevalence of allergic diseases such as asthma, allergic rhinitis, food allergy and atopic dermatitis has increased dramatically in recent decades. Conventional therapies for allergy can induce undesirable effects and hence patients tend to seek alternative therapies like natural compounds. Considering the fact above, there is an urgency to discover potential medicinal plants as future candidates in the development of novel anti-allergic therapeutic agents. The Lamiaceae family, or mint family, is a diverse plant family which encompasses more than 7,000 species and with a cosmopolitan distribution. A number of species from this family has been widely employed as ethnomedicine against allergic inflammatory skin diseases and allergic asthma in traditional practices. Phytochemical analysis of the Lamiaceae family has reported the presence of flavonoids, flavones, flavanones, flavonoid glycosides, monoterpenes, diterpenes, triterpenoids, essential oil and fatty acids. Numerous investigations have highlighted the anti-allergic activities of Lamiaceae species with their active principles and crude extracts. Henceforth, this review has the ultimate aim of compiling the up-to-date (2018) findings of published scientific information about the anti-allergic activities of Lamiaceae species. In addition, the botanical features, medicinal uses, chemical constituents and toxicological studies of Lamiaceae species were also documented. The method employed for data collection in this review was mainly the exploration of the PubMed, Ovid and Scopus databases. Additional research studies were obtained from the reference lists of retrieved articles. This comprehensive summarization serves as a useful resource for a better understanding of Lamiaceae species. The anti-allergic mechanisms related to Lamiaceae species are also reviewed extensively which aids in future exploration of the anti-allergic potential of Lamiaceae species.

Abstract
The prevalence of cardiovascular diseases (CVDs) is increasing at a rapid pace in developed countries, and CVDs are the leading cause of morbidity and mortality. Natural products and ethnomedicine have been shown to reduce the risk of CVDs. Schizonepeta (S.) tenuifolia is a medicinal plant widely used in China, Korea, and Japan and is known to exhibit anti-inflammatory, antioxidant, and immunomodulatory activities. We hypothesized that given herbal plant exhibit pharmacological activities against CVDs, we specifically explored its effects on platelet function. Platelet aggregation was evaluated using standard light transmission aggregometry. Intracellular calcium mobilization was assessed using Fura-2/AM, and granule secretion (ATP release) was measured in a luminometer. Fibrinogen binding to integrin αⅡbβ3, was assessed using flow cytometry. Phosphorylation of mitogen-activated protein kinase (MAPK) signaling molecules and activation of the protein kinase B (Akt) was assessed using Western blot assays. S. tenuifolia, extract potently and significantly inhibited platelet aggregation, calcium mobilization, granule secretion, and fibrinogen binding to integrin αⅡbβ3. Moreover, all extracts significantly inhibited MAPK and Akt phosphorylation. S. tenuifolia extract inhibited platelet aggregation and granule secretion, and attenuated collagen mediated GPVI downstream signaling, indicating the potential therapeutic effects of these plant extracts on the cardiovascular system and platelet function. We suggest that S. tenuifolia extract may be a potent candidate to treat platelet-related CVDs and to be used as an antiplatelet and antithrombotic agent.

Immunomodulation Effects of Schizonepeta tenuifolia Briq. on the IgE-Induced Allergic Model of RBL-2H3 Cells. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2018; 2018:6514705. [PMID: 29849717 PMCID: PMC5937521 DOI: 10.1155/2018/6514705] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/14/2017] [Revised: 02/20/2018] [Accepted: 02/28/2018] [Indexed: 12/15/2022]
Abstract
Schizonepeta tenuifolia (ST) Briq. is a traditional herbal medicine commonly used to treat allergic skin diseases, where the inflammation process is closely related to symptom severity. This study aimed to explore the immunomodulatory effect of ST by using immunoglobulin E- (IgE-) stimulated RBL-2H3 cell cultures, a common cell line for studying mast cell degranulation and inflammatory cytokine release in vitro. After stimulating the RBL-2H3 cells with IgE, ST at concentrations of 10, 50, or 100 μg/mL was added to the cell cultures. Cell viability, inflammatory cytokines (IL-6, IL-13, IL-4, TNF-α, and IFN-γ), anti-inflammatory cytokine IL-10, and degranulation ability were examined 48 and 72 hours after administration of ST. The markers of inflammation and allergic reaction, IFN-γ, TNF-α, IL-4, and IL-6, were suppressed, especially after treatment with 100 μg/mL ST. However, the anti-inflammation marker IL-10 was also suppressed by ST. Trend analysis showed that a higher ST concentration was associated with lower IFN-γ and TNF-α levels. Moreover, degranulation of RBL-2H3 cells was assessed by measuring the release of β-hexosaminidase, which was suppressed by ST at 10 μg/mL. This study showed an immunomodulatory effect of ST at the cellular level and suggests the role of ST in treating allergic diseases.

Anti-inflammatory effect of volatile oil from Schizonepeta tenuifolia on carrageenin-induced pleurisy in rats and its application to study of appropriate harvesting time coupled with multi-attribute comprehensive index method. JOURNAL OF ETHNOPHARMACOLOGY 2016; 194:580-586. [PMID: 27765609 DOI: 10.1016/j.jep.2016.10.045] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/25/2016] [Revised: 08/23/2016] [Accepted: 10/14/2016] [Indexed: 05/06/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Schizonepeta tenuifolia Briq. (ST) herbs have been used as a Traditional Chinese Medicine (TCM) for treating colds for thousands of years. The volatile oil is considered as the main material basis responsible for the efficacy of ST and has attracted lots of attention on its anti-inflammatory effect recently. AIM OF STUDY This paper investigated the anti-inflammatory effects of the distilled volatile oils from Schizonepeta tenuifolia (STVO) that were collected at different harvesting times on carrageenin-induced pleurisy in rats. Based on the anti-inflammatory effects, instead of contents of marker components, we aim to evaluate the quality and determine the appropriate harvesting time of ST. MATERIALS AND METHODS There were eleven groups with eight male rats in each randomly. They were model group, control group, positive group (dexamethasone) and eight groups treated with eight STVOs at different harvesting times. All treatments were performed by gavage and administered once a day on four consecutive days. One hour after the last treatments, except the rats in control group, those in other groups were treated with carrageenin to induce the pleurisy. Four hours later, all the rats were sacrificed and their pleurisy exudates and lung tissues were collected for further analysis. To evaluate the comprehensive anti-inflammatory effect of the eight STVOs, multi-attribute comprehensive index method (MACIM) was used to obtain the integration of various effects. RESULTS All the eight STVOs could decrease the seven indicators relating to pleurisy, which were exudate volume, leukocytes, protein level, myeloperoxidase (MPO), malondialdehyde (MDA), tumor necrosis factor-α (TNF-α) and interleukine-1β (IL-1β). Majority of these decreases were significant (P<0.01, P<0.05). As far as each indicator was concerned, each STVO showed different effect from others. With MACIM, it was found that STVO in Group 6 was the most effective one with the highest Vs and appropriate harvesting time of ST was in late September. CONCLUSIONS The study may provide scientific basis to further understanding of the mechanism of STVO in anti-inflammatory effect of carrageenin-induced pleurisy. Meanwhile, this study also provides a new access to determining the appropriate harvesting time of TCM and even evaluating the quality of TCM.

Abstract
It has long been believed that mast cells play a crucial role in the development of many physiological changes during immediate allergic responses. This study was conducted to evaluate the anti-inflammation mechanism of Schizonepeta tenuifolia (ST) extract and ST purified chemicals on the PMA plus A23187-induced stimulation of HMC-1 human mast cells. ST, rosmarinic acid, pulegone, and 2α,3α,24-thrihydrooxylen-12en-28oic acid treatment of HMC-1 cells led to significant suppression of pro-inflammatory cytokines (IL-6, IL-8, and TNF-α) in a dose dependent manner. In addition, the results of the microarray and real-time RT-PCR analyses revealed that ST regulates several pathways, including the cytokine-cytokine receptor interaction (CCRI), MAPK, and the Toll-like receptor (TLR) signaling pathways. ST may be useful for the treatment of inflammation disease via anti-inflammation activity that occurs through inhibition of the CCRI, MAPK, and TLR signaling pathways.

Abstract
Schizonepeta tenuifolia (ST) is a well-known herb to treat the cold and its associated headache. However, the anti-inflammatory mechanism of ST in mouse peritoneal macrophages is not clear. In this study, we demonstrated that ST inhibited lipopolysaccaride (LPS)-induced tumor necrosis factor (TNF)-α and interleukin (IL)-6 production. The maximal inhibition rate of TNF-α and IL-6 production by ST (2 mg/ml) was 48.01 ± 2.8% and 56.45 ± 2.8%, respectively. During the inflammatory process, cyclooxygenase (COX)-2 and inducible nitric oxide synthase (iNOS) were increased in mouse peritoneal macrophages. However, treated with ST decreased the protein level of COX-2 and iNOS, as well as the production of PGE2and NO in LPS-stimulated mouse peritoneal macrophages. In addition, ST inhibited the phosphorylation of MAPK. Taken together, the results of this study suggest an important molecular mechanism by which ST reduces inflammation, which may explain its beneficial effect in the regulation of inflammatory reactions.

Abstract
In the present study, the acute, subacute and genetic toxicity of schizonepetin was assessed. The median lethal dose (LD(50)) of schizonepetin after oral administration was 478 mg/kg body weight in mice. Studies on dose toxicity were repeatedly conducted at 0, 60, 120, and 240 mg/kg bw/day in rats for 35 days after oral administration. Based on the results of this study, a dose level of 120 mg/kg bw/day is considered the no-observed-adverse-effect-level (NOAEL) in rats. Schizonepetin was negative in Salmonella typhimurium tester strains TA97, TA98, TA100, TA102 and TA1535, nonclastogenic in Chinese hamster lung (CHL) cells in the mammalian chromosome aberration test, and micronucleus formation were observed and no clinical signs or adverse effects were detected, and our results illustrated that schizonepetin is not genotoxic.

Abstract
A GC-MS-Selected Ion Monitoring (SIM) detection method was developed for simultaneous determination of four monoterpenes: (−)-menthone, (+)-pulegone, (−)-limonene and (+)-menthofuran as the main bio-active and toxic constituents, and four other main compounds in the volatile oils of Schizonepeta tenuifolia (ST) leaves and spikes at different harvesting times. The results showed that the method was simple, sensitive and reproducible, and that harvesting time was a possible key factor in influencing the quality of ST leaves, but not its spikes. The research might be helpful for determining the harvesting time of ST samples and establishing a validated method for the quality control of ST volatile oil and other relative products.

Abstract
Rheumatoid arthritis (RA) is a chronic inflammatory joint disease associated with matrix metalloproteinase (MMP)-3, leading to destruction of the cartilage. The objective of this study was to investigate and discuss the suitability of the 35 medicinal plants as therapeutic candidates to treat RA. Fibroblast-like synoviocytes (FLSs), derived from patients with RA, were adjusted to 2 × 10(6) cells/mL in a 24-well plate and pretreated with the distilled water extracts of the 35 plants (1, 10, and 100 µg/mL) for 1 h followed by interleukin-1β (IL-1β) (1 ng/mL) for 24 h. The concentration of MMP-3 was then determined using a Duoset ELISA Kit. The six plants (Artemisiae Capillaris Herba, AC; Bambusae Caulis In Taeniam, BC; Cassiae Semen, CS; Corni Fructus, CF; Leonuri Herba, LH; Schizonepetae Spica, SS) showed no toxicity, including MMP-3. The MMP-3 level was increased by 3.38-fold (212.23 μg/mL) in IL-1β-stimulated FLSs. The IL-1β-induced MMP-3 level was significantly and dose-dependently reduced by >50% by the six plants (P < 0.01: at 100 μg/ mL of CS and LH, P < 0.001: at 10 μg/mL of all plants, and at 100 μg/mL of AC, BC, CF, and SS). This is the first study on the MMP-3 inhibitory effect of the examined plants in FLSs isolated from RA patients. From our original research, the six candidate plants were identified.

Abstract
OBJECTIVES The anti-inflammatory effects of an aqueous extract of Schizonepeta tenuifolia on lipopolysaccharide (LPS)-induced tumour necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6) in vivo and in vitro have been investigated. METHODS C57BL/6 mice were orally administered phosphate-buffered saline (control) or S. tenuifolia water extract (50, 200, 500 or 1000 mg/kg) for 10 days before intraperitoneal administration of LPS (1.3 mg/kg). Blood samples were obtained 1 h after LPS challenge, followed by determination of TNF-alpha and IL-6 levels. Peritoneal macrophages from thioglycollate-injected mice were obtained and stimulated with LPS and S. tenuifolia water extract for viability assay, cytokine analysis, real-time RT PCR and Western blotting. KEY FINDINGS Oral administration of S. tenuifolia water extract to mice significantly reduced LPS-induced serum levels of TNF-alpha, but not IL-6. When peritoneal macrophages were treated in vitro with S. tenuifolia water extract, the inhibition of LPS-induced TNF-alpha was more pronounced than that of IL-6 at the level of secreted protein and mRNA. S. tenuifolia water extract reduced the degradation of IkappaBalpha and the nuclear relocation of p65 NF-kappaB, but the phosphorylation of IkappaBalpha was not affected. Inhibition of c-Jun N-terminal kinase/stress-activated protein kinase (JNK/SAPK) by S. tenuifolia water extract led secondarily to the inhibition of phospho-c-Jun and phospho-ATF-2. CONCLUSIONS These results indicated that the downregulation of TNF-alpha by S. tenuifolia water extract may have involved the inhibition of both IkappaBalpha degradation and activation of c-Jun and ATF-2 involving suppression of JNK/SAPK.

Abstract
Abstract
Schizonepeta tenuifolia (ST) is a major herbal constituent included in treatments for the common cold with fever, ostitis media and other skin inflammations. The present study investigated the effect of ST water extract on the pattern of cytokine production from activated T cells in-vivo and in-vitro. When ST (200 mgkg−1) was given orally to mice for 7 days before i.v. injection of anti-CD3 antibody, it significantly decreased mRNA levels of interleukin (IL)-4, interferon (IFN)-γ and T-bet. Our flow cytometric analysis showed that ST administration significantly increased CD69 expression but showed little effect on the subsets of T cells. When we cultured mouse CD4 T cells under Th1/Th2 differentiation in the presence of ST, the suppressive activity of ST on IFN-γ involved T-bet, but the downregulation of IL-4 occurred independently of the Th2 transcription factors GATA binding protein 3 (GATA-3) and c-Maf. However, it increased IL-2 secretion during Th1/Th2 differentiation. Our study demonstrates that ST regulates inflammatory responses by reducing the release of Th1 and Th2 cytokines from T cells and prevents unprimed CD4 T cells from differentiating into Th1 and Th2 cells.

Abstract
The effect was investigated of the aqueous extract of Rubus coreanus Miq. (Rosaceae) fruits (RCAE) on systemic and local anaphylaxis. RCAE (0.01-1 g/kg) dose-dependently inhibited systemic anaphylaxis induced by compound 48/80 in mice. RCAE (1 g/kg) also significantly inhibited local anaphylaxis activated by anti-DNP IgE. Pretreatment with RCAE at the same concentration before systemic anaphylaxis reduced the plasma histamine levels in a dose-dependent manner. RCAE (0.001-1 mg/mL) dose-dependently inhibited the histamine release from rat peritoneal mast cells (RPMC) activated by compound 48/80 or anti-DNP IgE. The level of cAMP in RPMC, when RCAE was added, significantly increased, compared with that of the normal control. Moreover, RCAE (0.01-1 mg/mL) had a significant inhibitory effect on anti-DNP IgE-induced tumour necrosis factor-alpha production from RPMC. These results indicate that RCAE may possess antianaphylactic action.

Abstract
This article presents an up-to-date review of the plant Schizonepeta tenuifolia (Jingjie), of family Labiatae, with respect to its traditional uses, chemical constituents, various pharmacological activities, and clinical effects. Nonetheless, its mechanism of actions, adverse effects, drug interactions, and contraindications remain unclear. With the global growth on the use of herbal products, Jingjie has been commonly marketed for the treatment of common cold and fever in Chinese proprietary medicines. Hence, further studies will be warranted to show its efficacy and safety.

Abstract
We studied the effect of aqueous extract of Prunella vulgaris (Labiatae) (PVAE) on immediate-type allergic reactions. PVAE (0.005 to 1 g/kg) dose-dependently inhibited systemic anaphylactic shock induced by compound 48/ 80 in rats. When PVAE was given as pretreatment, at concentrations ranging from 0.005 to 1 g/kg, the serum histamine levels induced by compound 48/ 80 were reduced in a dose-dependent manner. PVAE (0.001 to 1 g/kg) inhibited the passive cutaneous anaphylaxis activated by anti-dinitrophenyl (DNP) IgE antibody dose dependently. PVAE also inhibited the histamine release induced by compound 48/80 or anti-DNP IgE from the rat peritoneal mast cells (RPMC). The level of cyclic AMP in RPMC, when PVAE was added, significantly increased, compared with that of normal control. Moreover, PVAE (0.01 and 0.1 mg/ml) had a significant inhibitory effect on anti-DNP IgE-mediated tumor necrosis factor-alpha production from RPMC. These results indicate that PVAE inhibits immediate-type allergic reactions in rats.
