Introduction Phyllanthus niruri is a traditional shrub of the genus Phyllanthaceae with long-standing Ayurvedic, Chinese and Malay ethnomedical records. Preliminary studies from cell and animal model have provided valuable scientific evidence for its use. Aim This review aims to summarize selected scientific evidence on the pharmacological properties of P. niruri over the past 35 years while identifying potential areas of further development of this herb as an economical adjunct. Methods The review covers literature pertaining to the evidence base therapeutic potential of P. niruri spanning from 1980 to 2015 available on PubMed.Results Evidence suggests that the extracts of P. niruri possess hepatoprotective, antiviral, antibacterial, hypolipidaemic, hypoglycaemic, analgesic, anti-inflammatory, cardioprotective, anti-urolithiatic and antihyperuricaemic properties due its novel bioactive compounds. Conclusion Scientific evidence suggests that there is strong pharmacological potential in developing P. niruri as a drug to be used in liver disorders and in antiviral therapy. Despites this, large-scale heterogeneity in study protocol and unstandardized reporting standards limit the ability for valuable comparison and may mask the ability to replicate these studies. Thus interpretation of findings should be performed with caution and further studies should be performed in line with best practices. More cheminformatics, toxicological and mechanistic studies would aid the progress to clinical trial studies.

Coronavirus disease 2019 (COVID-19) originated in China in early March 2019. Saudi Food and Drug Authorityapproved the registration of the Pfizer-BioNTech COVID-19 vaccine in Saudi Arabia on December 10, 2020 and on May 10, 2021, Pfizer-BioNTech was given an authorized emergency use in 12 to 15 years old children. Saudi Arabia’s Ministry of Health started Pfizer-BioNTech COVID-19 vaccination for 12 to 18 years old on June 27, 2021. Here we have a case of 16-year-old female admitted to the medical ward diagnosed with acute inflammatory transverse myelitis after two weeks from second dose of the Pfizer-BioNTech COVID-19 vaccine. The diagnosis was based on normal laboratory workup but significant radiological findings. She was discharged after a full recovery.There are multiple cases of post-vaccine acute inflammatory transverse myelitisshared by medical journals, but due to lack of literature review for the teenager population, we think our case may be the first case of acute inflammatory transverse myelitis following second dose of Pfizer-BioNTech COVID-19 vaccine in this population.

The aim of this study was to explore the phytochemical composition, heavy metals analysis and the antibacterial activity of six medicinal plants i.e., Terminalia chebula Retz (fruits), Aegle marmelos L., (fruits), Curcuma longa L., (rhizomes), Syzygium aromaticum L., (flower buds), Piper nigrum L., (seeds), Cinnamomum cassia L., (barks) and its two remedial recipes (recipe 1 and 2) used against diarrhea obtained from the local herbal practitioners (Hakeems). A preliminary phytochemical screening of the above-mentioned plants extract in methanol, chloroform, n-hexane and distilled water revealed the presence of various constituents such as alkaloids, flavonoids, tannins and saponins by using standard procedures. The quantitative phytochemical studies shows that alkaloids, flavonoid and saponins were in maximum amount in Terminalia chebula. The concentration of Cd, Ni, Pb, Fe, Cr, Cu and Zn were investigated by using an atomic absorption spectrometer. The obtained analysis shows that Cr, Fe and Pb were present in the highest concentration in medicinal plants and their recipes. The antibacterial activities of the crude extract found in the recipes of methanol, chloroform, n-hexane and distilled water were analyzed by using agar well disc diffusion assay and minimum inhibitory concentration (MIC) by broth dilution method against four bacterial strains, namely, E. coli, Salmonella, Shigella and Methicillin-resistant Staphylococcus aureus (MRSA), respectively. The maximum zones of inhibition in methanol, water, chloroform and n-hexane extracts were seen in recipe 2 against Shigella (22.16 ± 0.47 mm), recipe 2 against Shigella (20.33 ± 0.24 mm), recipe 1 against Shigella (20.30 ± 0.29 mm) and recipe 2 against E. coli (30.23 ± 0.12 mm), respectively. Furthermore, the recipe extracts are more active against the tested bacterial strains than the extracts from individual plants. Therefore, it is concluded that the use of herbal plants and their recipes are the major source of drugs in a traditional medicinal system to cure different diseases.Medicinal plants can act as an indigenous source of new compounds possessing therapeutic value and can also be used in drugs development. According to the World Health Organization (WHO), plants can provide different varieties of drugs for low-income nations to cope with their primary healthcare needs [1]. The plants are medicinally important due to the presence of biologically active secondary metabolites such as alkaloids, flavonoids, steroids, saponins and terpenoids, which exert their effects by interacting with human physiology. The antimicrobial activities of these phytochemicals are due to their chemical nature [2,3] and are a potential source of diarrheal disease [4]. For this reason, the WHO has encouraged the studies for the treatment and prevention of diarrheal diseases using traditional medicinal practices [5]. Presently, a large number of medicinal plants are being used in many countries of the world, including Pakistan, due to their anti-diarrheal properties [6]. In Bangla...
