A wound is a break in the continuity of the skin. The body’s response to injury and the restoration of the same is healing. Wound healing is a biological process that is initiated by trauma and often terminated by scar formation. In this research, guava leaf extract was used as antiseptic and its efficacy was tested to commercially available products. The result revealed that all mice which received guava leaf extract formed scar earlier as compared to povidone iodine and PNSS. Since maturation phase which also refers to remodeling phase is responsible for the new epithelium and final scar tissue formation, and as the development of these completes the complex process of wound healing, the researchers suggest that the use of guava leaf extract in comparison with povidone iodine and PNSS when it comes to wound healing is the most affordable in treatment and promoting normal and more rapid wound healing.

Inflammation in sebaceous follicles leads to skin related maladies more specifically, acne vulgaris. Bacterial species involved in causing such maladies involve P. acnes, S. epidermidis, S. aureus. These microbes have negatively affected the currently available remedies for acne vulgaris. In this research herbal Nigella sativa, Achyranthes aspera seeds were used instead of using any chemical based product on skin. The present study aims to develop novel antibacterial gel using Nigella sativa, Achyranthes aspera seeds to target pathogens that cause dermal acne. To extract the antibacterial property of the seed, they were soaked in desired chemicals individually in a shaker and then evaporated by using a rotary evaporator. After the extraction the extract was screed using the agar gel well diffusion method against P. acnes as well as S. aureus. From the diffusion method it was found that the extract is loaded with antibacterial properties. Now, the extract of N. sativa and A. aspera seeds was further divided into gels of 2 different concentrations and subjected for stability evaluation of antimicrobial activity. In this research it was found that the antibacterial property of the 10% of seed extract used was surpassed the commercial synthetic product. In addition, it was found that there were no changes in colour, pH, odor, consistency, homogeneity, and washing capacity, although the antibacterial potential was physiologically stable during storage time. The strong antimicrobial property produced from the extract in topical gel formulations suggests that the formulation can be a potential alternative to current remedies in the treatment of acne vulgaris.

Aims: To study the anti-HIVs and anti-bacterial activity and investigate the chemical compositions of the crude extracts and isolated compounds from stems and twig of Ficus dubia.
Methodology: Twigs and stems of Ficus dubia were collected from Si Sawat District, Kanchanaburi Province, Thailand. Bioactivity assay and phytochemical analysis of ficus dubia were processed under standard method including, anti-HIV1-RT, antibacterial activities, and CC chromatography procedures. Structures of the compound were elucidated by spectroscopic techniques.
Results: Bioactivities assay exposed that, the hexane, ethyl acetate, and methanol extracts of Ficus dubia were verified for anti-HIV and anti-bacterial activities. The ethyl acetate and methanol extract showed evidence of anti-HIVs-1RT inhibition at 69.02 % and 69.24 %, respectively. Anti-syncytium (MC99+1A2) among evaluated all three extracts: it afforded the lowest EC50; hexane 9.65 (TI 4.39), ethyl acetate 11.15 (TI 3.84), and methanol 43.61 (TI 3.04). Moreover, an antibacterial study on extract was also performed. The antibacterial study was evaluated using nine strains (Staphylococcus aureus, Enterobacter aerogenes, Escherichia coli 0157: H7, Escherichia coli (ETEC), Escherichia coli (EPEC), Proteus mirabilis, Salmonella typhimurium, Shigella flexneri, and Vibrio cholera) by Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) method. The MeOH extract was the most effective antibacterial with a MIC in the range >0.1 mg/mL and MBC in the range >0.2 mg/mL. However, the isolated compounds from this plant had not been studied in all bioassay. Phytochemical examination of stems and twigs from Ficus dubia had directed to the isolation of four known compounds, epifriedelanol, β-sitosterol, stigmasterol, and bergapten.

Chia seeds (Salvia hispanica L.) are small seeds that develop on an annual herbaceous plant. Recently, there has been tremendous growth in the use of chia seeds because of their associated medicinal as well as high nutritional values. Initially, chia cultivation took place in Mesopotamian cultures, eventually disappearing for some centuries before being rediscovered in the mid-20th Century. In this paper, the main aim has been to provide an overview of chia seed in relation to its perceived medicinal properties. From the majority of scholarly affirmations, it has been established that some of the compounds that chia seeds contain, explain its associated healthful effects include minerals, vitamins, proteins, dietary fiber, polyunsaturated fatty acids, and ω-3 fatty acids. Also, the literature contends that chia seeds are excellent sources of antioxidants and polyphenols, which include quercetin, myricetin, rosmarinic acid, and caffeic acid. Around the world, therefore, more and more scholarly investigations have focused on some of the beneficial effects of chia seeds, including the food, pharmaceutical, and medicinal industries. In this paper, it has been established that chia seeds have their medicinal properties gained in terms of pharmacological activities that include steatohepatitis and acute dyslipidemia improvement, sensory attributes, bioactive peptide and protein source, metabolic profile, and antioxidant and appetite suppressing properties. Important to note is that while most studies concur regarding these medicinal properties, in a few investigations, findings suggest that chia seeds do not pose significant beneficial effects, especially concerning health improvements in human subjects. As such, there is a need for future research to examine some of the parameters that could explain this variation, upon which more valid and informed conclusions and inferences might be made.

The sustained interest in the design of potent antioxidants drugs over the years can be attributed to the indispensable roles antioxidants play in the mitigation of oxidative stress and its concomitant diseases. The high demand for exogenous antioxidants has been ascribed to the prevalence of oxidative stress-mediated diseases such as cancer, diabetes, stroke, cell aging, arteriosclerosis and central nervous system disorders occasioned by a biochemical disequilibrium between the production of free radicals and the body’s ability to eliminate these reactive species from the biological system. COVID-19 severity and death have been linked to a free radical generating process known as the cytokine storm. In an attempt to maintain optimal body function, antioxidant supplementation has increasingly become a wide spread practice because of antioxidants’ ability to directly scavenge free radicals, inhibit oxidative chain reactions thereby increasing the antioxidant defenses of the body. Recent data showed that researchers had made significant efforts to demonstrate the importance and timeliness of antioxidant therapy based on drug design from natural and synthetic sources. Therefore this review presents antioxidant drug design methodologies, identifying the lead and hits to provide a historical and up-to-date collection of research briefs on antioxidant drug design into a single piece in order to ensure easy accessibility, motivate readership and inspire future researches.
