    Natural products like plants and its components have been in use for treatment and cure of diseases all around the globe from ancient times much before the discovery of the current modern drugs. These substances from the nature are well known to contain components which have therapeutic properties and can also behave as precursors for the synthesis of potential drugs. The beneficial results from herbal drugs are well reported where their popularity in usage has increased across the globe. Subsequently developing countries are now recognizing the many positive advantages from their use which has engaged the expansion of R & D from herbal research. The flow on effect from this expansion has increased the awareness to develop new herbal products and the processes, throughout the entire world. Mouth washes and mouth rinses which have plant oils, plant components or extracts have generated particular attention. High prevalence of gingival inflammation and periodontal diseases, suggests majority of the patients practice inadequate plaque control. Of the currently available mouthwashes in the market, Chlorhexidine gluconate (CHX) has been investigated on a larger scale with much detail. CHX is associated with side effects like staining of teeth when used daily as well as the bitter taste of the mouthwash which leads to patient incompliance. The present research encompasses the antibacterial activity of extemporaneously prepared herbal mouthwash using natural herbs and therefore allows for the potential commercialization with in the herbal and pharmaceutical industries. Also, the present research article reviewed details of various existing patents of herbal mouthwashes which shows the trend of existing market and significance of emerging mouthwashes in both pharmaceutical and herbal industries. The antimicrobial activity of prepared mouthwashes was found to be effective against various strains of bacteria. It also suggests that the prepared herbal mouthwashes may provide an alternative to those containing chemical entities, with enhanced antimicrobial properties and better patient compliance.

  4. Evaluation of anthelmintic properties of extracts from some plants used as livestock dewormers by pastoralist and smallholder farmers in Kenya against Heligmosomoides polygyrus infections in mice
    Githiori JB, Höglund J, Waller PJ, Leyden Baker R
    Vet Parasitol, 2003 Dec 30;118(3-4):215-26.
    PMID: 14729169
    Parasitic nematodes are among the most common and economically important infectious diseases of grazing livestock, especially in small ruminants in the tropics and subtropics in Kenya the control of gastrointestinal nematode infections in sheep and goats is usually made with synthetic anthelmintics but substantial levels of anthelmintic resistance have been recorded. A number of medicinal plants, that may provide possible alternatives, and are used by pastoralists and smallholder farmers in Kenya as deworming agents for their livestock and equines, namely Aframomum sanguineum, Dodonea angustifolia, Hildebrandtia sepalosa, Myrsine africana, Rapanea melanophloeos from Kenya, and Azadirachta indica from Kenya and Malaysia, together with the chemicals embelin and santonin that occur in some of these plants, were evaluated against Heligmosomoides polygyrus in mice. Commercial anthelmintics, namely ivermectin, pyrantel and piperazine, were also investigated, both to validate the mouse model system and to assess efficacy of these drugs against H. polygyrus. Pyrantel and ivermectin were highly effective in reducing the numbers of H. polygyrus worms as well as eggs in faeces of the mice, but piperazine had a lower activity. Application of santonin and M. africana significantly reduced the number of total worm counts (TWC) but not faecal egg counts (FEC). The use of embelin, R. melanophloeos and A. indica reduced FEC but not TWC. In all cases, however, reductions were well below the a priori level of 70% required for biological significance. A. sanguineum, D. angustifolia and H. sepalosa had no effect on either TWC or FEC. In conclusion, none of the plant preparations had any biologically significant anthelmintic effect in this monogastric host-parasite model system.

  5. Nitric oxide, human diseases and the herbal products that affect the nitric oxide signalling pathway
    Achike FI, Kwan CY
    Clin Exp Pharmacol Physiol, 2003 Sep;30(9):605-15.
    PMID: 12940876
    1. Nitric oxide (NO) is formed enzymatically from l-arginine in the presence of nitric oxide synthase (NOS). Nitric oxide is generated constitutively in endothelial cells via sheer stress and blood-borne substances. Nitric oxide is also generated constitutively in neuronal cells and serves as a neurotransmitter and neuromodulator in non-adrenergic, non-cholinergic nerve endings. Furthermore, NO can also be formed via enzyme induction in many tissues in the presence of cytokines. 2. The ubiquitous presence of NO in the living body suggests that NO plays an important role in the maintenance of health. Being a free radical with vasodilatory properties, NO exerts dual effects on tissues and cells in various biological systems. At low concentrations, NO can dilate the blood vessels and improve the circulation, but at high concentrations it can cause circulatory shock and induce cell death. Thus, diseases can arise in the presence of the extreme ends of the physiological concentrations of NO. 3. The NO signalling pathway has, in recent years, become a target for new drug development. The high level of flavonoids, catechins, tannins and other polyphenolic compounds present in vegetables, fruits, soy, tea and even red wine (from grapes) is believed to contribute to their beneficial health effects. Some of these compounds induce NO formation from the endothelial cells to improve circulation and some suppress the induction of inducible NOS in inflammation and infection. 4. Many botanical medicinal herbs and drugs derived from these herbs have been shown to have effects on the NO signalling pathway. For example, the saponins from ginseng, ginsenosides, have been shown to relax blood vessels (probably contributing to the antifatigue and blood pressure-lowering effects of ginseng) and corpus cavernosum (thus, for the treatment of men suffering from erectile dysfunction; however, the legendary aphrodisiac effect of ginseng may be an overstatement). Many plant extracts or purified drugs derived from Chinese medicinal herbs with proposed actions on NO pathways are also reviewed.

  6. Fulltext Bacteria as a source of oviposition attractant for Aedes aegypti mosquitoes
    Arbaoui AA, Chua TH
    Trop Biomed, 2014 Mar;31(1):134-42.
    PMID: 24862053 MyJurnal
    Since a safe and effective mass vaccination program against dengue fever is not presently available, a good way to prevent and control dengue outbreaks depends mainly on controlling the mosquito vectors. Aedes aegypti mosquito populations can be monitored and reduced by using ovitraps baited with organic infusions. A series of laboratory experiments were conducted which demonstrated that the bacteria in bamboo leaf infusion produce volatile attractants and contact chemical stimulants attractive to the female mosquitoes. The results showed that the female mosquitoes laid most of their eggs (59.9 ± 8.1 vs 2.9 ± 2.8 eggs, P<0.001) in bamboo leaf infusions when compared to distilled water. When the fresh infusion was filtered with a 0.45 μm filter membrane, the female mosquitoes laid significantly more eggs (64.1 ± 6.6 vs 4.9 ± 2.6 eggs, P<0.001) in unfiltered infusion. However when a 0.8 μm filter membrane was used, the female laid significantly more eggs (62.0 ± 4.3 vs 10.1 ± 7.8 eggs, P<0.001) in filtrate compared to a solution containing the residue. We also found that a mixture of bacteria isolated from bamboo leaf infusion serve as potent oviposition stimulants for gravid Aedes mosquitoes. Aedes aegypti laid significantly more eggs (63.3 ± 6.5 vs 3.1 ± 2.4 eggs, P<0.001) in bacteria suspension compared to sterile R2A medium. Our results suggest microbial activity has a role in the production of odorants that mediate the oviposition response of gravid mosquitoes.

    Jacob SA, Khan TM, Lee LH
    Nutr Cancer, 2017 Apr;69(3):353-364.
    PMID: 28287319 DOI: 10.1080/01635581.2017.1285037
    This systematic review aimed to assess the clinical benefits of green tea consumption on the progression and prevention of prostate cancer (PCa). A systematic search was performed across the following databases: PubMed, Excerpta Medica dataBASE, Database of Abstracts of Reviews of Effects, Current Nursing and Allied Health Literature, Allied and Complementary Medicine Database, Cochrane Database of Systematic Reviews, and Cochrane Central Register of Controlled Trials. We included studies from database inception to September 2015. Studies must report on the effect of green tea consumption on PCa. The quality of observational studies was assessed using the Newcastle-Ottawa Scale (NOS), while randomized controlled trials (RCTs) were assessed for quality using the Jadad scale. A total of 15 articles were included, with 11 reporting on the effect of green tea consumption on PCa prevention, and four reporting on the effect of green tea on treatment. Mean NOS for observational studies was 7.4 (SD±1.3), with a range from 6 to 9, while all three RCTs scored 5 on the Jadad scale. Findings demonstrate that green tea appears to be an effective chemopreventive agent, particularly in those with high-grade prostate intraepithelial neoplasia. However, evidence of efficacy in the treatment of PCa is currently lacking. Given the limitations in current studies, more well-designed RCTs should be undertaken to determine if green tea indeed has a role in the prevention and treatment of PCa.

    Tumpang MA, Ramli NA, Hussain Z
    Curr Drug Targets, 2018;19(6):674-700.
    PMID: 28914203 DOI: 10.2174/1389450118666170913162147
    BACKGROUND: Phytomedicines have been well-accepted alternative complementary therapies for the treatment of a wide range of acute and chronic skin inflammatory diseases including chronic herpes, prurigo, psoriasis, and atopic dermatitis (AD). A plethora of in vitro and in vivo studies have evidenced the therapeutic viability of phytomedicines, polyherbal formulations, plant-based materials and their decoctions for the treatment of mild-to-severe AD.

    OBJECTIVE: This review was aimed to summarize and critically discuss the convincing evidence for the therapeutic effectiveness of phytomedicines for the treatment of AD and explore their anti-AD efficacy.

    RESULTS: The critical analysis of a wide algorithm of herbal medicines revealed that their remarkable anti-AD efficacy is attributed to their potential of reducing erythema intensity, oedema, inflammation, transepidermal water loss (TEWL) and a remarkable suppression of mRNA expression of ADassociated inflammatory biomarkers including histamine, immunoglobulin (Ig)-E, prostaglandins, mast cells infiltration and production of cytokines and chemokines in the serum and skin biopsies.

    CONCLUSION: In conclusion, herbal medicines hold great promise as complementary and alternative therapies for the treatment of mild-to-moderate AD when used as monotherapy and for the treatment of moderate-to-severe AD when used in conjunction with other pharmacological agents.

    Hakim L, Alias E, Makpol S, Ngah WZ, Morad NA, Yusof YA
    Asian Pac J Cancer Prev, 2014;15(11):4651-7.
    PMID: 24969899
    The development of chemopreventive approaches using a concoction of phytochemicals is potentially viable for combating many types of cancer including colon carcinogenesis. This study evaluated the anti-proliferative effects of ginger and Gelam honey and its efficacy in enhancing the anti-cancer effects of 5-FU (5-fluorouracil) against a colorectal cancer cell line, HCT 116. Cell viability was measured via MTS (3-(4,5-dimethylthiazol-2- yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulphenyl)-2H-tetrazolium) assay showing ginger inhibiting the growth of HCT 116 cells more potently (IC50 of 3mg/mL) in comparison to Gelam honey (IC50 of 75 mg/mL). Combined treatment of the two compounds (3mg/mL ginger+75 mg/mL Gelam honey) synergistically lowered the IC50 of Gelam honey to 22 mg/mL. Combination with 35 mg/mL Gelam honey markedly enhanced 5-FU inhibiting effects on the growth of HCT 116 cells. Subsequent analysis on the induction of cellular apoptosis suggested that individual treatment of ginger and Gelam honey produced higher apoptosis than 5-FU alone. In addition, treatment with the combination of two natural compounds increased the apoptotic rate of HCT 116 cells dose- dependently while treatment of either ginger or Gelam honey combined with 5-FU only showed modest changes. Combination index analysis showed the combination effect of both natural compounds to be synergistic in their inhibitory action against HCT 116 colon cancer cells (CI 0.96 < 1). In conclusion, combined treatment of Gelam honey and ginger extract could potentially enhance the chemotherapeutic effect of 5-FU against colorectal cancer.

    Goh TB, Koh RY, Mordi MN, Mansor SM
    Asian Pac J Cancer Prev, 2014;15(14):5659-65.
    PMID: 25081682
    BACKGROUND: To investigate the antioxidant value and anticancer functions of mitragynine (MTG) and its silane-reduced analogues (SRM) in vitro.

    MATERIALS AND METHODS: MTG and SRM was analyzed for their reducing power ability, ABTS radical inhibition and 1,1-diphenyl-2-picryl hydrazylfree radicals scavenging activities. Furthermore, the antiproliferation efficacy was evaluated using MTT assay on K 562 and HCT116 cancer cell lines versus NIH/3T3 and CCD18-Co normal cell lines respectively.

    RESULTS: SRM and MTG demonstrate moderate antioxidant value with ABTS assay (Trolox equivalent antioxidant capacity (TEAC): 2.25±0.02 mmol trolox / mmol and 1.96±0.04 mmol trolox / mmol respectively) and DPPH (IC50=3.75±0.04 mg/mL and IC50=2.28±0.02 mg/mL respectively). Both MTG and SRM demonstrate equal potency (IC50=25.20±1.53 and IC50= 22.19±1.06 respectively) towards K 562 cell lines, comparable to control, betulinic acid (BA) (IC5024.40±1.26). Both compounds showed concentration-dependent cytototoxicity effects and exert profound antiproliferative efficacy at concentration > 100 μM towards HCT 116 and K 562 cancer cell lines, comparable to those of BA and 5-FU (5-Fluorouracil). Furthermore, both MTG and SRM exhibit high selectivity towards HCT 116 cell lines with selective indexes of 3.14 and 2.93 respectively compared to 5-FU (SI=0.60).

    CONCLUSIONS: These findings revealed that the medicinal and nutitional values of mitragynine obtained from ketum leaves that growth in tropical forest of Southeast Asia and its analogues does not limited to analgesic properties but could be promising antioxidant and anticancer or chemopreventive compounds.

  14. Potential Functional Byproducts from Guava Purée Processing
    Lim SY, Tham PY, Lim HYL, Heng WS, Chang YP
    J Food Sci, 2018 Jun;83(6):1522-1532.
    PMID: 29745989 DOI: 10.1111/1750-3841.14155
    The valorization of guava waste requires compositional and functional studies. We tested three byproducts of guava purée processing, namely refiner, siever, and decanter. We analyzed the chemical composition and quantified the prebiotic activity score and selected carbohydrates; we also determined the water holding (WHC), oil holding (OHC), cation exchange capacities, bile acid binding, and glucose dialysis retardation (GDR) of the solid fraction and the antioxidative and α-amylase inhibitory capacities (AIC) of the ethanolic extract. Refiner contained 7.7% lipid, 7.08% protein and a relatively high phytate content; it had a high prebiotic activity score and possessed the highest binding capacity with deoxycholic acid. Siever contained high levels of low molecular weight carbohydrates and total tannin but relatively low crude fiber and cellulose contents. It had the highest binding with chenodeoxycholic acid (74.8%), and exhibited the highest 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging capacity. Decanter was rich in cellulose and had a high prebiotic activity score. The WHC and OHC values of decanter were within a narrow range and also exhibited the highest binding with cholic acid (86.6%), and the highest values of GDR and AIC. The refiner waste could be included in animal feed but requires further processing to reduce the high phytate levels. All three guava byproducts had the potential to be a source of antioxidant dietary fiber (DF), a finding that warrants further in vivo study.

    PRACTICAL APPLICATION: To differing extents, the guava byproducts exhibited useful physicochemical binding properties and so possessed the potential for health-promoting activity. These byproducts could also be upgraded to other marketable products so the manufacturers of processed guava might be able to develop their businesses sustainably by making better use of them.

    Husen R, Pihie AH, Nallappan M
    J Ethnopharmacol, 2004 Dec;95(2-3):205-8.
    PMID: 15507337 DOI: 10.1016/j.jep.2004.07.004
    Screening of aqueous extract of Phyllantus niruri (PL), Zingiber zerumbet (ZG), Eurycoma longifolia (TA-a and TA-b) and Andrographis paniculata (AP) to determine their blood glucose lowering effect were conducted in normoglycaemic and Streptozotocin-induced hyperglycaemic rats. Significant reduction in blood glucose level at 52.90% was shown when hyperglycaemic rats were treated with 50 mg/kg body weight (BW) aqueous extract of AP. This effect is enhanced when freeze-dried material was used, where 6.25 mg/kg BW gave 61.81% reduction in blood glucose level. In the administration of TA-a and TA-b, positive results in hyperglyacaemic rats were only obtained when 150 mg/kg BW of the aqueous extract was used. No significant reduction in blood glucose level were shown in hyperglycaemic rats treated with PL and ZG at all concentrations used (50, 100 and 150 mg/kg BW). In normoglycaemic rats, no significant reduction was noted when all the same extracts were used.

    PMID: 28865618 DOI: 10.1016/j.foodres.2016.08.016
    Edible seaweeds are a good source of antioxidants, dietary fibers, essential amino acids, vitamins, phytochemicals, polyunsaturated fatty acids, and minerals. Many studies have evaluated the gelling, thickening and therapeutic properties of seaweeds when they are used individually. This review gives an overview on the nutritional, textural, sensorial, and health-related properties of food products enriched with seaweeds and seaweed extracts. The effect of seaweed incorporation on properties of meat, fish, bakery, and other food products were highlighted in depth. Moreover, the positive effects of foods enriched with seaweeds and seaweed extracts on different lifestyle diseases such as obesity, dyslipidemia, hypertension, and diabetes were also discussed. The results of the studies demonstrated that the addition of seaweeds, in powder or extract form, can improve the nutritional and textural properties of food products. Additionally, low-fat products with less calories and less saturated fatty acids can be prepared using seaweeds. Moreover, the addition of seaweeds also affected the health properties of food products. The results of these studies demonstrated that the health value, shelf-life and overall quality of foods can be improved through the addition of either seaweeds or seaweed extracts.

    Toxicological studies constitute an essential part of the effort in developing an herbal medicine into a drug product. A newly developed thymoquinone-rich fraction nanoemulsion (TQRFNE) has been prepared using a high pressure homogenizer. The purpose of this study was to investigate the potential acute toxicity of this nanoemulsion in Sprague Dawley rats. The acute toxicity studies were conducted as per the OECD guidelines 425, allowing for the use of test dose limit of 20 mL TQRFNE (containing 44.5 mg TQ)/kg. TQRFNE and distilled water (DW) as a control were administered orally to both sexes of rats on Day 0 and observed for 14 days. All the animals appeared normal, and healthy throughout the study. There was no observed mortality or any signs of toxicity during the experimental period. The effects of the TQRFNE and DW groups on general behavior, body weight, food and water consumption, relative organ weight, hematology, histopathology, and clinical biochemistry were measured. All the parameters measured were unaffected as compared to the control (DW) group. The administration of 20 mL TQRFNE /kg was not toxic after an acute exposure.
