Exploring the safety and clinical use of herbal medicine in the contemporary Ghanaian context: A descriptive qualitative study

Pesticide residue detection technology for herbal medicine: current status, challenges, and prospects

The domains of cancer therapy, disease prevention, and health care greatly benefit from the use of herbal medicine. Herbal medicine has become the mainstay of developing characteristic agriculture in the planting area increasing year by year. One of the most significant factors in affecting the quality of herbal medicines is the pesticide residue problem caused by pesticide abuse during the cultivation of herbal medicines. It is urgent to solve the problem of detecting pesticide residues in herbal medicines efficiently and rapidly. In this review, we provide a comprehensive description of the various methods used for pesticide residue testing, including optical detection, the enzyme inhibition rate method, molecular detection methods, enzyme immunoassays, lateral immunochromatographic, nanoparticle-based detection methods, colorimetric immunosensor, chemiluminescence immunosensor, smartphone-based immunosensor, etc. On this basis, we systematically analyze the mechanisms and some of the findings of the above detection strategies and discuss the challenges and prospects associated with the development of pesticide residue detection tools.

Cervicofacial necrotizing fasciitis after topical application of herbal medicine

Cervical necrotizing fasciitis represents an aggressive form of deep neck space infection with a high mortality rate. The origin is generally odontogenic, in most cases, resulting from a dental abscess. A series of three cases developed after local application of herbal medicine in patients with no co-morbidities and with a history of a toothache in the lower quadrants for >2 weeks is presented. All patients were managed with antibiotics, extraction of offending tooth and serial wound debridement. Two patients recovered with a resultant skin defect on the neck and one died due to multiple organ failure. This case series demonstrated that early diagnosis, prompt surgical intervention and appropriate medical treatment are very important to increase patient survival. Late report to hospital because of financial constraints and over-reliance on herbal preparation could lead to the development of serious complication in patients with dental infections and could even lead to death of the patient.

Facilitators and barriers of herbal medicine use in diabetic patients: A qualitative study

BACKGROUND

In several countries such as Iran, the use of complementary and alternative medical products like herbal medicine is growing. There is, however, a lack of research on the prospects of herbal medicine patrons regarding facilitators and herbal medicine use barriers. The aim of this study was to explain the facilitators and the barriers of herbal medicine use in type 2 diabetes mellitus (T2DM) patients.

MATERIALS AND METHODS

Qualitative one-to-one in-depth interviews were conducted with patients with T2DM from the Yazd Diabetes Research Center, using a semi-structured guide. For the recruitment of T2DM participants who used herbal medicine beside conventional medicine, purposeful sampling was used. Analysis of the data was carried out using the steps proposed by Graneheim and Landman strategies.

RESULTS

Sixteen patients were interviewed. There were 2 subjects (facilitators and barriers herbal medicine use), 8 categories, and 89 initial codes. The facilitators included individual preferences, preparation skills, and family support and the factors obstructing the use of herbal medicine included insufficient skills about preparing, lack of easy access to consumption, insufficient of efficacy of herbal medicine, and negative properties of herbal medicine and taking time in preparing herbal medicine.

CONCLUSION

Although some people use herbal medicine, the interest in use of herbal medicine is limited because of inadequate awareness of the impact and usage them. Therefore, the use of effective strategy in the integration of herbal remedies with conventional medicine can promote well-being of patients.

Impacts of heavy metals and medicinal crops on ecological systems, environmental pollution, cultivation, and production processes in China

Heavy metals are widely distributed in the environment due to the natural processes and anthropogenic human activities. Their migration into no contaminated areas contributing towards pollution of the ecosystems e.g. soils, plants, water and air. It is recognized that heavy metals due to their toxicity, long persistence in nature can accumulate in the trophic chain and cause organism dysfunction. Although the popularity of herbal medicine is rapidly increasing all over the world heavy metal toxicity has a great impact and importance on herbal plants and consequently affects the quality of herbal raw materials, herbal extracts, the safety and marketability of drugs. Effective control of heavy metal content in herbal plants using in pharmaceutical and food industries has become indispensable. Therefore, this review describes various important factors such as ecological and environmental pollution, cultivation and harvest of herbal plants and manufacturing processes which effects on the quality of herbal plants and then on Chinese herbal medicines which influence human health. This review also proposes possible management strategies to recover environmental sustainability and medication safety. About 276 published studies (1988-2021) are reviewed in this paper.

Current Awareness of Health Professionals on the Safety of Herbal Medicine and Associated Factors in the South West of Ethiopia

Background

Recently, the World Health Organization has strongly evidenced the importance of herbal medicine safety monitoring within the existing pharmacovigilance system through active involvement of health professionals. However, there is a widespread lack of awareness among health professionals about the safety of herbal medicines. Thus, this study assessed the current awareness of health professionals on the safety of herbal medicine in the South West of Ethiopia.

Methodology

The study employed a cross-sectional study design involving multistage sampling among health professionals (n=286) working in the medical center of Jimma University, January to February, 2021. The pre-tested self-administered questionnaire containing structured questions on a five-point Likert scale was appropriately filled and returned for statistical analysis. For the analysis of data, Statistical Package for Social Sciences (SPSS) was used. The associations between status of awareness and predictors were determined at 5% (p<0.05) level of significance by employing multivariate logistic regression.

Results

The study revealed around 51.8% of respondents had a good awareness regarding herbal medicine safety. Working experience of 6-10 years (AOR: 0.215, 95% CI: 0.093, 0.499), having training (AOR: 0.357, 95% CI: 0.166, 0.770), and practice of safety monitoring (AOR: 0.169, 95% CI: 0.077, 0.370) were significantly associated with awareness of safety of herbal medicine.

Conclusion

This study revealed that awareness of health professionals regarding safety of herbal medicine is not satisfactory. The years of experience, training, and practice of safety monitoring of herbal medicine are the major factors affecting status awareness. Therefore, the National Regulatory Authority must urgently facilitate integrated and consistent training for all health professionals.

A qualitative exploration of the norms and intentions of nurses toward the clinical use of herbal medicine in Ghana

PURPOSE

The purpose of the study was to determine the norms and intentions of nurses towards the clinical use of herbal medicine.

METHOD

Information on nurses' demographics, norms and intentions was gathered through individual face-to-face interviews. Interviews were analysed using the process of content analysis.

RESULTS

Beliefs of the nurses and motivational factors formed their norms. The nurses believed herbal medicine was God-given and was used by their ancestors with good outcomes. Some were self-motivated to serve herbal medicine while others counted on patient's recovery upon the use of herbal medicine to motivate them. Positive and negative intentions were discovered; thus, preparedness and unpreparedness to serve herbal medicine in the future.

CONCLUSIONS

Though some nurses believe herbal medicine is God-given, used by their ancestors and motivated to serve, others were unwilling because of inadequate training. Training of professional nurses on herbal medicine may improve their negative intentions.

Modulation of cancer signalling pathway(s) in two -stage mouse skin tumorigenesis by annonacin

Background

Annonacin, an annonaceous acetogenin isolated from Annona muricata has been reported to be strongly cytotoxic against various cell lines, in vitro. Nevertheless, its effect against in vivo tumor promoting activity has not been reported yet. Therefore, this study was aimed to investigate antitumor-promoting activity of annonacin via in vivo two-stage mouse skin tumorigenesis model and its molecular pathways involved.

Methods

Mice were initiated with single dose of 7,12-dimethylbenz[α]anthracene (DMBA) (390 nmol/100 μL) followed by, in subsequent week, repeated promotion (twice weekly; 22 weeks) with 12-O-tetradecanoylphorbol-13-acetate (TPA) (1.7 nmol/100 μL). Annonacin (85 nM) and curcumin (10 mg/kg; reference) were, respectively, applied topically to DMBA/TPA-induced mice 30 min before each TPA application for 22 weeks. Upon termination, histopathological examination of skin, liver and kidney as well as genes and proteins expression analysis were conducted to elucidate the potential mechanism of annonacin.

Results

With comparison to the carcinogen control, Annonacin significantly increased the tumor latency period and reduced the tumor incidence, tumor burden and tumor volume, respectively. In addition, it also suppressed tumorigenesis manifested by significant reduction of hyperkeratosis, dermal papillae and number of keratin pearls on skin tissues. Annonacin also appeared to be non-toxic to liver and kidney. Significant modulation of both AKT, ERK, mTOR, p38, PTEN and Src genes and proteins were also observed in annonacin-targeted signaling pathway(s) against tumorigenesis.

Conclusions

Collectively, results of this study indicate that annonacin is a potential therapeutic compound targeting tumor promoting stage in skin tumorigenesis by modulating multiple gene and protein in cancer signaling pathways without apparent toxicity.

Identifying strengths and weaknesses of the integration of biomedical and herbal medicine units in Ghana using the WHO Health Systems Framework: a qualitative study

Background

The use of herbal medicines in developing countries has been increasing over the years. In Ghana, since 2011, the government has been piloting the integration of herbal medicine in 17 public hospitals. However, the strengths and the weaknesses of the integration have not been fully explored. The current study sought to examine the strengths and weaknesses of the integration using the WHO health systems framework.

Methods

This study used qualitative, exploratory study design involving interviews of 25 key informants. The respondents had experience in conducting herbal medicine research. Two key informants were medical herbalists practising in hospitals piloting the integration in Ghana. We used Framework analysis to identify the perspectives of key informants in regards to the integration. 

Results

Key informants mostly support the integration although some noted that the government needs to support scale-up in other public hospitals. Among the strengths cited were the employment of medical herbalists, utilization of traditional knowledge, research opportunities, and efficient service delivery by restricting the prescription and use of fake herbal medicine. The weaknesses were the lack of government policies on implementing the integration, financial challenges because the National Health Insurance Scheme does not cover herbal medicine, poor advocacy and research opportunities, and lack of training of conventional health practitioners in herbal medicine.

Conclusions

Researchers view the integration of the two healthcare systems–biomedicine, and herbal medicine– positively but it has challenges that need to be addressed. The integration could offer more opportunities for researching into herbal medicine. More training for conventional health professionals in herbal medicine could increase the chances of better coordination between the two units. Additionally, strong advocacy and publicity is needed to educate more people on the integration and the utilization of the services.

The State of Nursing Research in Ghana: An Integrative Literature Review

INTRODUCTION

For nursing practice to be responsive to the needs of patients, it must be driven by contextual research evidence. To guide institutional and national nursing research policy, there is need to determine the quantity and quality of nursing research in Ghana.

PURPOSE

The purpose of this integrative literature review was to quantify, critically evaluate, and describe nursing research publication in Ghana from January 2007 to December 2016 with regard to the country's research capacity to sustain evidence-based practice.

RESULTS

Sixty (60) out of 749 articles identified from EBSCOhost, ProQuest, PubMed, Science Direct, Scopus, Wiley Online Library, and Google Scholar using three keywords (nursing, health, and Ghana) were included. A total of 60,778 human subjects were used in these studies. There were more quantitative (28) studies than qualitative (23) studies. These studies recorded 219 authors from 120 institutions, 55 of which were outside Ghana. Forty-five percent of the articles were published in journals with impact factor. There was a steady increase in publication in Ghana over the decade. A majority of the studies published in education were in curriculum implementation and evaluation.

CONCLUSIONS

The increasing number of peer-reviewed nursing research publications in Ghana and the curriculum implementation and evaluation in Ghana signified an increasing capacity of the country to implement and sustain evidence-based practice.

RECOMMENDATIONS

It is recommended that regular research be conducted to evaluate the responsiveness to old and new nursing programs in Ghana.
