Nausea and vomiting of pregnancy (NVP) is one of the prevalent pregnancy complaints. This study was conducted to review the medicinal plants mentioned in Traditional Persian Med­icine (TPM) for the treatment of NVP. A literature research was conducted on a number of main references of TPM, including the books of al-Qanun fī al-Teb, Zakhireye Kharazmshahi, Tadbir-al-Habali al- Atfal al-Sabiban and Makhzan-al-Adviah. Then, medicinal plants mentioned in TPM for treatment of NVP were determined and searched in electronic databases, including PubMed and Google Scholar to find studies that confirmed their efficacy. The search terms were ‘‘vomiting’’ or ‘‘nausea’’ or “emesis” and “pregnancy” and the name of each herb. Data were collected for the years 1990–2016. The findings included 10 plants. Citrus limon (Lemon), Citrus medica L. (Citron), Cydonia oblonga (Quince), Elletaria cardamomum (Cardamom), Mentha spicata L. (Spearmint), Menatha piperita (Mint), Myristica fragrans Houtt (Nutmeg), Pistacia lentiscus Linn. (Mastic), Punica granatum L. (Pomegranate), Malus domestica Borkh (Apple), and Piper cubeba L. are the most recommended medications for NVP. There is evidence in human studies for some of these medicinal plants (Mentha Piperita L., Citrus limon, Elletaria cardamom, and Cydonia oblonga Mill). The other mentioned herbs have not been evaluated during pregnancy. There is limited evidence to safely recommend these plants for NVP. Although some human studies have suggested the antiemetic effects of TPM remedies, their safety is not sufficiently documented in modern literature. Scientific studies on these medicinal plants during pregnancy are warranted to determine their safety. [GMJ.2017;6(4):281-90] DOI: 10.22086/gmj.v0i0.809

Abstract An ethnobotanical study was conducted to document indigenous medicinal plants and their usage from knowledgeable and elderly persons in Razzar and Gadoon valley of Swabi and Allai and Tanawal valley of Hazara region of Pakistan during 2016-2019. Several systematic field visits and questionnaire surveys were carried out in selected sites of the study area to gather relevant information from the local community. Rapid assessment method was adopted for data collection by interviewing the local people having enough knowledge of medicinal plants use for treatment of different ailments. UV (UV) formula was applied to calculate the relative importance of medicinal plant species in each site of the study area. In the present study, 221 medicinal plants belonging to 105 families have been reported through 580 respondents (385 males, 138 females and 57 local health healer) from the Swabi and Hazara region. The main sources of herbal medicines were leaves (21%) followed by fruits (21%), seeds (17%), whole plants (14%), roots (9%), bark (9%), flowers (7%) and gum (2%). Mentha spicata L. and Berberis lycium Royle were reported with highest UV (UV) i.e. 0.92 and 0.68 in Razzar tehsil and Gadoon valley of Swabi, whereas Mentha longifolia L and Geranium wallichianum D were reported with highest UV i.e. (0.65) and (0.88) in Allai and Tanawal valley of Hazara region, respectively. It was concluded that Swabi and Hazara region is rich in medicinal plants species and associated traditional knowledge. Moreover, ethno-medicines have played significant role in the indigenous healthcare system of the study area. However, uprooting the entire plant for ethno-medicine is a big threat to conservation of medicinal plants diversity in the study area.

Important Health Issue

The coronavirus disease 2019 (COVID-19) pandemic, caused by severe acute respiratory syndrome corona virus-2 (SARS-CoV-2), is the most important health issue, internationally. With no specific and effective antiviral therapy for COVID-19, new or repurposed antiviral are urgently needed. Phytochemicals pose a ray of hope for human health during this pandemic, and a great deal of research is concentrated on it. Phytochemicals have been used as antiviral agents against several viruses since they could inhibit several viruses via different mechanisms of direct inhibition either at the viral entry point or the replication stages and via immunomodulation potentials. Recent evidence also suggests that some plants and its components have shown promising antiviral properties against SARS-CoV-2. This review summarizes certain phytochemical agents along with their mode of actions and potential antiviral activities against important viral pathogens. A special focus has been given on medicinal plants and their extracts as well as herbs which have shown promising results to combat SARS-CoV-2 infection and can be useful in treating patients with COVID-19 as alternatives for treatment under phytotherapy approaches during this devastating pandemic situation.

AbstractInfectious bursal disease (IBD) caused by non-enveloped double stranded RNA virus is an acute and contagious poultry disease. Outbreak of IBD could result in 10–75% mortality of the birds; hence it has gained socio-economic importance worldwide. Medicinal plants have shown broad spectrum anti-viral activities against RNA and DNA viruses. Moringa oleifera Lam (MOL), Phyllanthus emblicus Linn (PEL), Glycyrrhiza glabra Linn (GGL), and Eugenia jambolana Lam (EJL) are commonly available medicinal plants of the sub-continent and exhibited anti-viral potential against different viruses. Ethanolic extracts of the leaves of MOL and EJL, roots of GGL and dried fruit of PEL were investigated for their cytotoxic and anti-viral potential against IBD virus using MTT colorimetric assay and anti-viral assay. Significant anti-viral potential (P<0.001) was demonstrated at concentrations 12.5, 25, 50 and 100 µg ml−1 of GGL, PEL, MOL and EJL, respectively, with no cytotoxicity. Data also spotlighted that all tested plant extracts possess significant anti-viral potential and this trend was higher in GGL followed by PEL, MOL, and EJL. The data undoubtedly conclude that these medicinal plants contain several health beneficial phyto-chemicals which got significant anti-viral potential and effectively be utilized against IBD virus. Moreover, the outcomes of this study provide a platform on the way to discover novel anti-viral agents against IBD virus and other viruses from plant origin.

Phytochemicals, especially botanical insecticides are currently of interest because of their successful application in plant protection as biocontrol agents. Biological activity of leaf aqueous extract of ten selected medicinal plants were evaluated against the fourth-instar larvae of gram pod borer Helicoverpa armigera (H¨ubner), (Lepidoptera: Noctuidae). Antifeedant activity of leaf aqueous extracts of Abutilon indicum L., Achyranthus aspera L., Aerva lanata L., Albiziz amara (Roxb), Andrographis paniculata Ness., Cardiospermum halicacabum L., Cassia tora L., Catharanthus roseus L (G) Don., Datura metal L. and Tribulus terrestris L. were evaluated in this study. Preliminary screening after 24 h of exposure with leaf aqueous extracts of the selected plants at a concentration of 1,000 ppm exhibited significant larval mortality rate. The percentage mortality rate ranged considerably from 10.8 to 72.8. The mortality rate was observed in the decreasing order of A. paniculata > C. roseus > D. metal > A. amara > C. halicacabum > A. indicum > C. tora > T. terrestris > A. aspera >A. lanata against the larvae of H. armigera. The results imply that leaf aqueous extract of A. paniculata, C. roseus and D. metal can potentially be used as eco-friendly pest control agents against the larva of H. armigera.
