    Ang HH, Lee KL, Kiyoshi M
    Int J Environ Health Res, 2004 Aug;14(4):261-72.
    PMID: 15369991
    The DCA (Drug Control Authority), Malaysia implemented the phase 3 registration of traditional medicines on 1 January 1992 with special emphasis on the quality, efficacy and safety (including the presence of heavy metals) in all pharmaceutical dosage forms of traditional medicinal preparations. As such, a total of 100 traditional medicinal preparations, containing Smilax myosotiflora, in various pharmaceutical dosage forms, which were bought in the Malaysian market, were analysed for lead content using atomic absorption spectrophotometry. Results showed that 15% of the products analysed possessed 10.23-23.05 ppm of lead, and therefore, do not comply with the quality requirement for traditional medicines in Malaysia. The quality requirement for traditional medicines in Malaysia is that they should not exceed 10 ppm of lead. Out of these 15 products, five products exhibited 10.23-23.05 ppm of lead, in fact they have already been registered with the DCA Malaysia. However, the rest of the products, which possessed 12.24-20.72 ppm of lead, have still not been registered with the DCA Malaysia. Although this study successfully showed that only 85% of the products complied with the quality requirement for traditional medicines in Malaysia pertaining to lead, they cannot, however, be assumed to be safe from lead contamination because of batch-to-batch inconsistency.

    Kazemipoor M, Hamzah S, Hajifaraji M, Radzi CW, Cordell GA
    Phytother Res, 2016 Jun;30(6):981-7.
    PMID: 26988309 DOI: 10.1002/ptr.5603
    Following the current 'Globesity' trend, there is an increasing demand for alternative natural therapies for weight management. Numerous phytoconstituents reduce body weight through suppressing appetite and reducing food intake. Caraway (Carum carvi L.) is one of the medicinal plants that is traditionally used for weight loss. In this study, the appetite-suppressing effects of caraway aqueous extract (CAE) on 70 aerobically trained, overweight, and obese women were examined in a triple-blind, placebo-controlled, clinical study. Subjects were randomly allocated into placebo and experimental groups and consumed either 30 mL/day of CAE or placebo without changing their diet or physical activity over a period of 90 days. Calorie and macronutrient intake and anthropometric indices were measured before and after the intervention. In addition, appetite changes were assessed through a visual analog scale and an ad libitum pizza test. After the intervention, the results showed a significant reduction in appetite levels and carbohydrate intake of the experimental group compared with the placebo group. All of the anthropometric indices were reduced significantly in CAE compared with placebo group (p

    PMID: 16019122
    Traditional herbal medicines, popularly known as 'jamu' and 'makjun' in Malaysia and Indonesia, are consumed regularly to promote health. In consideration of their frequent and prolonged consumption, the natural occurrence of aflatoxins (AF) in these products was determined using immunoaffinity column clean-up and high-performance liquid chromatography with pre-column derivatization. The evaluated method, which entails dilution of sample extracts with Tween 20-phosphate buffered saline (1:9, v/v) and a chromatographic system using isocratic mobile phase composed of water-methanol-acetonitrile (70:20:10, v/v/v), was effective in separating AFB1, AFG1 and AFG2 from interference at their retention times. Results were confirmed using post-column derivatization with photochemical reactor. For 23 commercial samples analyzed, mean levels (incidence) of AFB(1), AFB(2) and AFG1 in positive samples were 0.26 (70%), 0.07 (61%) and 0.10 (30%) microg/kg, respectively; one sample was positive for AFG2 at a level of 0.03 (4%) microg/kg. In contrast to the high levels of AF in crude herbal drugs and medicinal plants reported previously by other researchers, the low contamination levels reported in this study may be attributed to the higher selectivity to AF of the method applied. Based on the AFB1 levels and the daily consumption of positive samples, a mean probable daily intake of 0.022 ng/kg body weight was calculated.

    Biomed Pharmacother, 2017 Sep;93:596-608.
    PMID: 28686974 DOI: 10.1016/j.biopha.2017.06.087
    For many decades, natural herbal medicines, polyherbal formulations and/or decoctions of plant-derived materials have widely been accepted as alternative complementary therapies for the treatment, cure or prevention of a wide range of acute and chronic skin diseases including chronic herpes, prurigo, acute and chronic wounds, psoriasis and atopic dermatitis (AD). This review was aimed to summarize and critically discuss about the therapeutic viability and clinical applicability of natural herbal medicines for the treatment of AD in human. The critical analysis of the literature revealed that oral (in the form of capsules, syrup or granules) and/or topical application (alone or in conjunction with wet-wrap dressing and/or acupuncture) of natural herbal medicines exhibit remarkable potential for the treatment of mild-to-severe AD in adults, children, infants and in the pregnant women. In this review, the clinical efficacy of various herbal formulations such as Chinese herbal therapies, Korean medicines, Iranian medicines, honey, natural herbal oils (coconut oil, olive oil and mineral oil), beeswax, dodder seeds and whey for the treatment of AD has been discussed. The clinical anti-AD efficacy of these complementary therapies has been observed in terms of down-regulation in Scoring Atopic Dermatitis (SCORAD) index, erythematic intensity, Children's Dermatology Life Quality Index (CDLQI), Dermatology Life Quality Index (DLQI), pruritus and itching frequency, transepidermal water loss (TEWL) and expression of AD-mediated chemokines. Conclusively, we recognized that natural herbal medicines demonstrate remarkable clinical efficacy when used alone or in conjunction with other complementary therapies for the treatment of AD in patients of all ages as well as pregnant women.

    OBJECTIVES: Flipped classroom (FC) is a pedagogical model to engage students in learning process by replacing the didactic lectures. Using technology, lectures are moved out of the classroom and delivered online as means to provide interaction and collaboration. Poll Everywhere is an audience response system (ARS) which can be used in an FC to make the activities more interesting, engaging, and interactive. This study aims to study the perception of undergraduate pharmacy students on FC activity using Poll Everywhere ARS and to study the effectiveness of FC activity as a teaching-learning tool for delivering complementary medicine module in the undergraduate pharmacy program.

    MATERIALS AND METHODS: In this nonrandomized trial on interrupted time series study, flipped class was conducted on group of 112 students of bachelor of pharmacy semester V. The topic selected was popular herbal remedies of the complementary medicine module. Flipped class was conducted with audio and video presentation in the form of a quiz using ten one-best-answer type of multiple-choice questions covering the learning objectives. Audience response was captured using web-based interaction with Poll Everywhere. Feedback was obtained from participants at the end of FC activity and debriefing was done.

    RESULTS: Randomly selected 112 complete responses were included in the final analysis. There were 47 (42%) male and 65 (58%) female respondents. The overall Cronbach's alpha of feedback questionnaire was 0.912. The central tendencies and dispersions of items in the questionnaire indicated the effectiveness of FC. The low or middle achievers of quiz session (pretest) during the FC activity were three times (95% confidence interval [CI] = 1.1-8.9) at the risk of providing neutral or negative feedback than high achievers (P = 0.040). Those who gave neutral or negative feedback on FC activity were 3.9 times (95% CI = 1.3-11.8) at the risk of becoming low or middle achievers during the end of semester examination (P = 0.013). The multivariate analysis of "Agree" or "Disagree" and "Agree" or "Strongly Agree" was statistically significant.

    CONCLUSION: This study provides insight on how the pharmacy students learn and develop their cognitive functions. The results revealed that the FC activity with Poll Everywhere is an effective teaching-learning method.

    Rehman SU, Choe K, Yoo HH
    Molecules, 2016 Mar 10;21(3):331.
    PMID: 26978330 DOI: 10.3390/molecules21030331
    Eurycoma longifolia Jack (known as tongkat ali), a popular traditional herbal medicine, is a flowering plant of the family Simaroubaceae, native to Indonesia, Malaysia, Vietnam and also Cambodia, Myanmar, Laos and Thailand. E. longifolia, is one of the well-known folk medicines for aphrodisiac effects as well as intermittent fever (malaria) in Asia. Decoctions of E. longifolia leaves are used for washing itches, while its fruits are used in curing dysentery. Its bark is mostly used as a vermifuge, while the taproots are used to treat high blood pressure, and the root bark is used for the treatment of diarrhea and fever. Mostly, the roots extract of E. longifolia are used as folk medicine for sexual dysfunction, aging, malaria, cancer, diabetes, anxiety, aches, constipation, exercise recovery, fever, increased energy, increased strength, leukemia, osteoporosis, stress, syphilis and glandular swelling. The roots are also used as an aphrodisiac, antibiotic, appetite stimulant and health supplement. The plant is reported to be rich in various classes of bioactive compounds such as quassinoids, canthin-6-one alkaloids, β-carboline alkaloids, triterpene tirucallane type, squalene derivatives and biphenyl neolignan, eurycolactone, laurycolactone, and eurycomalactone, and bioactive steroids. Among these phytoconstituents, quassinoids account for a major portion of the E. longifolia root phytochemicals. An acute toxicity study has found that the oral Lethal Dose 50 (LD50) of the alcoholic extract of E. longifolia in mice is between 1500-2000 mg/kg, while the oral LD50 of the aqueous extract form is more than 3000 mg/kg. Liver and renal function tests showed no adverse changes at normal daily dose and chronic use of E. longifolia. Based on established literature on health benefits of E. longifolia, it is important to focus attention on its more active constituents and the constituents' identification, determination, further development and most importantly, the standardization. Besides the available data, more evidence is required regarding its therapeutic efficacy and safety, so it can be considered a rich herbal source of new drug candidates. It is very important to conserve this valuable medicinal plant for the health benefit of future generations.

    Introduction: The objective of this presentation is to carry out a review of the historical status and possible future outlook of the practice of ethnomedicine in the State of Sabah. As in many parts of the world, there are many types of traditional medicines that have been used for hundreds of years among the various native cultural groups in Sabah. Methods: A literature survey was conducted with the aid of online database, and text books using keywords such as the current as well as previous names of Sabah and various related terminology such as ethnomedicine, CAM, complementary and alternative medicine, TCM, traditional and complementary medicine, herbalism, reflexology, spiritualism, ethnobiology ethnology, ethnoanthropology, biological activities, ethnobotanical uses, medicinal prop-erties, toxicity studies, etc. The status of ethnomedicine in Sabah is largely unknown. Results: Based on a review of previous literature, the study discovered that there is limited empirical documentation on the use of ethnomedicine in Sabah. In this preliminary review, a total number of 25 publications were recorded in the databases for the period up to 2019. There is still a need to realise the full potential of the biocultural diversity of Sabah, and that there is a strong need to focus more on socially relevant research. Ethnomedicine in Sabah consists mainly of herbalism, ma-nipulative practices and spiritualism. Plants can be said to be the central player in race-based traditional medicine. While data on ethnomedicine may be based on original field research, several are primarily derivative, drawing as they do from earlier published accounts and, importantly, anecdotes. Traditional massage and other manipula-tive-practices, based on manipulation and movement of body parts, are also popular because of their simplicity and apparent immediate relief that can be experienced by the patient or client. Spiritualism, which may be considered as a peculiar dimension of the mind-body medicine subset of traditional medicine, continues to have its adherents among the natives of Sabah. Conclusion: List and catalogs and sociological and ethnohistorical data were the fa-voured perspective of research in the past; but future evolution of ethnomedical studies need to address some of the debates related to biological, medical and social sciences . Future research should include systematic inves-tigation into efficacy and risk besides the possible incorporation of some parts of ethnomedicine into the existing healthcare services. Ethnomedicine occupies a distinct place in healthcare in the world in general, and Sabah in particular.

    Introduction:Alternative treatment for cancer from herbal medicine has gained interest due to its benefits on im-mune modulation, improving the survival and quality of life. Mitragyna speciosa (M. speciosa) or Kratom is an indig-enous plant that can be found in Thailand and northern part of Peninsular Malaysia has becomes popular in recent years due to its ability to exhibit the opioid-like effects of analgesia. Mitragynine is the main alkaloid in M. speciosa which is found to reduce gastrointestinal motility and has been used by local communities as traditional treatment for diarrhoea and many other diseases. However, there is lack of scientific evidence to show that M. speciosa has anti-oxidative and anti-cancer properties especially in colorectal cancer. Therefore, our study aims to evaluate the anti-oxidative properties of M. Speciosa methanolic extract (MSME) and its effects on colorectal cancer cell line, SW480. Methods: The anti-oxidant content and scavenging activity of MSME were determined by total phenolic content (TPC) assay and total flavonoid content (TFC) assay as well as 2,2’-azino-bis (3-ethylbenzothiazoline-6-sul-phonic acid) (ABTS) assay and 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay respectively. Cytotoxicity and cytokine inhibitory effects of MSME on SW480 cells were determined by (3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxy-phenyl)-2-(4-sulfophenyl)-2H-tetrazolium) (MTS) and cytokine beads array (CBA), respectively. Results: The TPC of MSME (0.1mg/ml = 85.85 ± 8.25 mg GAE/g extract; 1mg/ml = 167.43 ± 13.50 mg GAE/g extract; 10mg/ml = 408.94 ±7.17 mg GAE/g extract) was lower than pterostilbene, the positive control drug (76.37 ± 2.75; 230.52 ± 10.92; 835.44 ± 6.84 mg GAE/g extract). Conversely, the TFC of MSME (0.1mg/ml = 32.17 ± 27.92 mg QE/g extract; 1mg/ml = 347.72 ± 15.97 mg QE /g extract; 10mg/ml = 739.81 ± 5.56 mg QE /g extract) was slightly higher than pteros-tilbene (ND; 212.73 ± 17.92; 700.50 ± 3.47 mg QE/g extract). In DPPH assay, MSME showed comparatively similar antioxidant scavenging activity (IC50=4.34μg/ml) with pterostilbene (IC50=4.393μg/ml). However, MSME showed lower anti-oxidant scavenging activity (IC50=4.26μg/ml) than pterostilbene (IC50=1.556μg/ml) as measured by ABTS assay. In cytotoxicity assay, IC50 of MSME on SW480 cells was determined to be at 1.486 mg/ml. Overexpression of cytokines such as IL-6, IL-8 (CXCR8) and IL-10 could potentially promote tumour cell proliferation, growth and metastasis. Increased production of these cytokines through LPS stimulation in SW480 was slightly reduced by treat-ment with MSME. Conclusion: MSME could have a potential bioactive compound that possesses anti-oxidative and anti-cancer properties that would be beneficial as an alternative treatment of colorectal cancer.

    Bassoumah, B., Adam, M.A.
    JUMMEC, 2018;21(1):32-38.
    MyJurnal
    The study aimed at government efforts in making maternal and child healthcare services more available to
    rural women, many of whom who still seek care from traditional practitioners during the postpartum period
    after childbirth. In this research, we explored the role of traditional practitioners, such as Traditional Birth
    Attendants (TBAs), herbalists and spiritualists, in traditional maternity care and the implications for the health
    of the expectant mother, foetus or baby. This qualitative inquiry used purposive sampling and snowballing to
    select the respondents in their various localities. It was observed that the traditional practitioners performed
    both spiritual and medical roles during pregnancy and childbirth.
    In the study, we discovered that both mothers and babies were exposed to health risks, as administration
    of the herbal medicines and assistance at deliveries were carried out under unhygienic conditions. The
    techniques used in labour management were not in compliance with the recommendations of the World
    Health Organisation. The stages of maternity were characterised with the application of herbal concoctions
    with spirituality attached.
    The study recommends re-examination of mediating socio-cultural factors to professional health care. There
    is a need for the Ghana Health Service to ensure the efficacy and safety of herbal drugs as well as to monitor
    the production and application of such medicines.

    Tarmizi AAA, Wagiran A, Mohd Salleh F, Chua LS, Abdullah FI, Hasham R, et al.
    Plants (Basel), 2021 Apr 07;10(4).
    PMID: 33917172 DOI: 10.3390/plants10040717
    Labisia pumila is a precious herb in Southeast Asia that is traditionally used as a health supplement and has been extensively commercialized due to its claimed therapeutic properties in boosting a healthy female reproductive system. Indigenous people used these plants by boiling the leaves; however, in recent years it has been marketed as powdered or capsuled products. Accordingly, accuracy in determination of the authenticity of these modern herbal products has faced great challenges. Lack of authenticity is a public health risk because incorrectly used herbal species can cause adverse effects. Hence, any measures that may aid product authentication would be beneficial. Given the widespread use of Labisia herbal products, the current study focuses on authenticity testing via an integral approach of DNA barcoding and qualitative analysis using HPLC. This study successfully generated DNA reference barcodes (ITS2 and rbcL) for L. pumila var. alata and pumila. The DNA barcode that was generated was then used to identify species of Labisia pumila in herbal medicinal products, while HPLC was utilized to determine their quality. The findings through the synergistic approach (DNA barcode and HPLC) implemented in this study indicate the importance of both methods in providing the strong evidence required for the identification of true species and to examine the authenticity of such herbal medicinal products.

    As in other parts of the world, the practice of traditional healing has been part of the local healthcare system for most of the indigenous ethnic groups, since time immemorial. Using descriptive research format, this study looked into the practice of a traditional medicine practitioner in one of the villages of Kota Marudu in Sabah, Malaysia. The practitioner comes from the Dusun Tagahas subethnic group which is one of the numerous ethnic groups in Sabah. The large number of ethnic group in Sabah has made the research of ethnomedicine rather challenging. The practitioner acquired knowledge of traditional healing and treatment which is mainly herbal medicines alluded with some spiritual aspects. He used many herbal preparations in various forms and applications. Similar to the other traditional medicine practitioners, his knowledge and skill regarding his practice are impressive but the practitioner is unable to explain on the mechanism of how the therapy works. Generally their philosophy rests on the notion that disease responds to right medicine but not explanation. There is an urgent need to capture all the knowledge and skill possessed by traditional medicine practitioners, who generally belong to an ageing and fading population, especially those live in remote and hard to reach areas. Scientific research should be conducted to help traditional medicine healers and herbalists to understand their practices before they suffer the consequences of inexorable extinction.

    A Central nervous system (CNS) disease is the one which affects either the spinal cord or brain and causing neurological or psychiatric complications. During the nineteenth century, modern medicines have occupied the therapy for many ailments and are widely used these days. Herbal medicines have often maintained popularity for historical and cultural reasons and also considered safer as they originate from natural sources. Embelin is a plant-based benzoquinone which is the major active constituent of the fruits of Embelia ribes Burm. It is an Indo-Malaysian species, extensively used in various traditional medicine systems for treating various diseases. Several natural products including quinone derivatives, which are considered to possess better safety and efficacy profile, are known for their CNS related activity. The bright orange hydroxybenzoquinone embelin-rich fruits of E. ribes have become popular in ethnomedicine. The present systematic review summarizes the effects of embelin on central nervous system and related diseases. A PRISMA model for systematic review was utilized for search. Various electronic databases such as Pubmed, Springer, Scopus, ScienceDirect, and Google Scholar were searched between January 2000 and February 2016. Based on the search criteria for the literature, 13 qualified articles were selected and discussed in this review. The results of the report showed that there is a lack of translational research and not a single study was found in human. This report gives embelin a further way to be explored in clinical trials for its safety and efficacy.

    Alafiatayo AA, Lai KS, Syahida A, Mahmood M, Shaharuddin NA
    Evid Based Complement Alternat Med, 2019;2019:3807207.
    PMID: 30949217 DOI: 10.1155/2019/3807207
    Curcuma longa L. is a rhizome plant often used as traditional medicinal preparations in Southeast Asia. The dried powder is commonly known as cure-all herbal medicine with a wider spectrum of pharmaceutical activities. In spite of the widely reported therapeutic applications of C. longa, research on its safety and teratogenic effects on zebrafish embryos and larvae is still limited. Hence, this research aimed to assess the toxicity of C. longa extract on zebrafish. Using a reflux flask, methanol extract of C. longa was extracted and the identification and quantification of total flavonoids were carried out with HPLC. Twelve fertilized embryos were selected to test the embryotoxicity and teratogenicity at different concentration points. The embryos were exposed to the extract in the E3M medium while the control was only exposed to E3M and different developmental endpoints were recorded with the therapeutic index calculated using the ratio of LC50/EC50. C. longa extract was detected to be highly rich in flavonoids with catechin, epicatechin, and naringenin as the 3 most abundant with concentrations of 3,531.34, 688.70, and 523.83μg/mL, respectively. The toxicity effects were discovered to be dose-dependent at dosage above 62.50μg/mL, while, at 125.0μg/mL, mortality of embryos was observed and physical body deformities of larvae were recorded among the hatched embryos at higher concentrations. Teratogenic effect of the extract was severe at higher concentrations producing physical body deformities such as kink tail, bend trunk, and enlarged yolk sac edema. Finally, the therapeutic index (TI) values calculated were approximately the same for different concentration points tested. Overall, the result revealed that plants having therapeutic potential could also pose threats when consumed at higher doses especially on the embryos. Therefore, detailed toxicity analysis should be carried out on medicinal plants to ascertain their safety on the embryos and its development.

    Cratoxylum arborescens (Vahl) Blume is an Asian herbal medicine with versatile ethnobiological properties including treatment of gastric ulcer. This study evaluated the antiulcerogenic mechanism(s) of α -mangostin (AM) in a rat model of ulcer. AM is a prenylated xanthone derived through biologically guided fractionation of C. arborescens. Rats were orally pretreated with AM and subsequently exposed to acute gastric lesions induced by ethanol. Following treatment, ulcer index, gastric juice acidity, mucus content, histological and immunohistochemical analyses, glutathione (GSH), malondialdehyde (MDA), nitric oxide (NO), and nonprotein sulfhydryl groups (NP-SH) were evaluated. The anti-Helicobacter pylori, cyclooxygenase-2 (COX-2) inhibitory effect, and antioxidant activity of AM were also investigated in vitro. AM (10 and 30 mg/kg) inhibited significantly (P < 0.05) ethanol-induced gastric lesions by 66.04% and 74.39 %, respectively. The compound induces the expression of Hsp70, restores GSH levels, decreases lipid peroxidation, and inhibits COX-2 activity. The minimum inhibitory concentration (MIC) of AM showed an effective in vitro anti-H. pylori activity. The efficacy of the AM was accomplished safely without presenting any toxicological parameters. The results of the present study indicate that the antioxidant properties and the potent anti-H. pylori, in addition to activation of Hsp70 protein, may contribute to the gastroprotective activity of α -mangostin.

    Obesity is one of the major public health problems worldwide and it is generally associated with many diseases. Although synthetic drugs are available for the treatment of obesity, herbal remedies may provide safe, natural, and cost-effective alternative to synthetic drugs. One example of such drugs is Melastoma malabathricum var Alba Linn (MM). Although several studies have been reported for the pharmacological activities of MM, there is no report on the anti-obesity effect of MM. The aim of the present study is to evaluate the anti-obesity potential of methanolic extract of MM. The anti-obesity effect of MM on rats fed with a high-fat diet was investigated through determination of the changes in body weight, fat weight, organ weights, and blood biochemicals. The animals in this study were divided into three groups: a normal group with a standard diet (N), a control group fed with high-fat diet (C), and a MM treatment group fed with high-fat (HFD + MM) diet for 8 weeks. There was no significant difference in the amount of food intake between control and HFD + MM treatments. These results also suggest that MM does not induce a dislike for the diet due to its smell or taste. The study shows that MM significantly prevented increases in body weight, cholesterol, LDL, HDL, and total lipids that resulted from the high-fat diet. MM also decreased the epididymal fat (E-fat) and retroperitoneal fat (R-fat) weights and phospholipid concentrations induced by the high-fat diet. On the basis of these findings, it was concluded that MM had anti-obesity effects by suppressing body weight gain and abdominal fat formation.

    PMID: 17243519
    A cross sectional survey on pattern and perception of herbal use among medical patients in Penang Hospital was conducted. Among 250 patients surveyed, 67.9% were using herbal medicine and conventional medicine concomitantly. A majority of the patients used herbs for health maintenance (51.3%) purpose. More than 90% of herbal users did not disclose herbal use to their physician and "Doctor never asked" was the major reason given (54.2%). The Chinese reported the highest rate of herbal use but was least likely to disclose. These findings are important for health professionals to ensure medication safety and recognise potential drug herb interaction.
