The present study investigates human health risks upon consumption of herbal medicines in terms of ten toxic metalloids in 20 plant-based anti-diabetic therapeutics. The analysis of metalloids was determined by an atomic absorption spectrometer after microwave-assisted digestion. The computation of hazard quotients (HQ) and hazard indexes (HI) of m...

The prevalence of erectile dysfunction is on the rise. Patients are turning to herbal drugs as an alternative to allopathic therapy or are drawn towards natural alternatives. However, there are concerns about the safety of these medications. An effort was made to determine the level of two commonly used water-soluble preservatives, sodium benzoate...

The present study evaluates the human health risk of metals in locally consumed herbal preparations used to treat diabetes. Atomic absorption spectroscopy (AAS) was used after microwave-assisted digestion to mineralize the samples. Toxic metal assessment was done by adopting mathematical modeling for carcinogenic and noncarcinogenic risks in the ex...

Having been a common healthcare distress, erectile dysfunction is upsetting the quality of life of men from all walks of life. Along with allopathic therapy, a sizable number of patients opt for energy-stimulating herbal drugs (ESHDs) to treat the ailment. However, a global threat vestige for metal contamination in plant-based drugs at above thresh...

Plant-based hypoglycemic therapeutics have been increasing in consumption due to the escalation of type 2 diabetes and its related complications. However, the safety of the preparations is little understood. Parabens (alkyl esters of p-hydroxybenzoic acid) are widely used as preservatives in these pharmaceuticals. However, the presence of methylpar...

The objective of the study was to assess sodium benzoate and potassium sorbate in some anti-diabetic herbal drugs (ADHDs) collected from local markets using UV-Vis spectrophotometric method. Analytes were measured in bulk and finished drug formulations at 224 nm for Sodium benzoate and 254.5 nm for potassium sorbate. The calibration curve obeyed Be...

Introduction. Along with and in competition with orthodox medicines, herbal medicines have converted into a popular form of cure. While cumulative investigation reports on adverse effects by herbal drug uptake are few, systematic review along with deep insight into other relevant topics (carcinogenic and noncarcinogenic risk assessment, mechanism o...

Herbal medicines are becoming increasingly popular, thereby being used in a vast amount. Prime reasons for this ample amount of popularity are clever marketing techniques fed on perceived safety. However, without proven clinical trial these claims come undone. This poses a threat to public health and drug safety as well. As a result, the whole heal...

In Bangladesh, during Ramadan for fulfilling a Muslim Sunnah, breaking fast with dates is considered divine. Consequently, its demand surges. An investigation was conducted into searching biological contaminations (microbial load) in dates from Dhaka South City Corporation (DSCC). Total Aerobic Bacterial Count (TABC) was found in all the samples wi...

Ubiquitous nature of erectile dysfunction (ED) has placed it as one of the most rampant health care problem and therefore consumption of energy stimulating herbal medicines (ESHMs) has increased in Bangladesh. However, these herbal medicines reaching consumers without maintaining proper screening procedure, which bring a threat to public health saf...

In this study, we examined the antioxidant, anthelmintic, and cytotoxic activities of methanol extract of Zizyphus oenoplia leaves (MEZO) in both experimental and computational models. Here, the computational study (in silico molecular docking) was carried out to identify the potential lead compounds of this plant for antioxidant and anthelmintic a...

Assessment of toxic metals in date fruits collected during Ramadan from different market sites within Dhaka city of Bangladesh have been carried out. Detection of toxic metals like Zn (0.07-0.15 mg/100 g), Cu (0.08-0.28 mg/100 g), Mn (0.80-1.25 mg/100 g) and Fe (0.54-1.90 mg/100 g) were found within safety limit for consumption with respect to inte...

The present study evaluated biological and physical contamination in terms of microbes and toxic metal, respectively, in eight antidiabetic herbal medicines (ADHMs) from different markets in Dhaka City, Bangladesh. Coliform, E. coli, Salmonella spp. and Listeria spp. were absent in all ADHMs. However, aerobic bacterial count of all the samples of y...

Widespread escalation of type 2 diabetes is a concern throughout the world. Developing countries are leading with patients suffering from diabetes-related complications. Plant-based therapeutic, antidiabetic herbal preparations (ADHPs) are being sought for long and the consumption is increasing in in Bangladesh. Plant-based antidiabetic preparation...

Background: Vitex peduncularis (Verbenaceae), popularly known as "Boruna," "Goda," "Ashmul gaas" (Chakma), "Korobaong" (Marma), is frequently used in the traditional medicine for the treatment of chest pain, joint ache, malarial fevers, diabetes, jaundice, urethritis, and abnormality in eyes and face. Objective: To validate the traditional use, thi...

It is evident that date fruits provide a wide variety of essential nutrients which impart potential human health benefits. In Bangladesh, the popularity of date and its consumption surge few-fold during Ramadan among Muslims owing to the profound emotion related to religious belief that breaking of dawn-to-dusk fasting with dates is fulfilling a Su...

The synthesis of superabsorbent polymer with Carboxymethyl cellulose using ceric ammonium nitrate (CAN) initiated acrylamide (AA) monomer through a solution based graft copolymerization has been conducted. The characterizing studies were performed using Fourier transform infrared (FTIR) spectroscopy, Atomic force microscopy (AFM) and swelling studi...

Chitosan-silver nanoparticles are prepared in nonaqueous medium. In this work, sodium dodecyl sulfate (SDS) was introduced into the dimethylformamide (DMF) solution during silver reduction from solution of its precursor salt AgNO 3, acting as a stabilizing agent to prevent aggregation of silver nanoparticles, while chitosan is used as the solid sup...
