Tea, next to water, is the beverage humans consume. Drinking the beverage tea is great for joining and collecting family members and public communities since ancient times. Tea plant Camellia sinensis has been cultivated for thousands of years, and its leaves have been used for medicinal purposes. Various studies suggest that polyphenolic compounds present in green and black tea are associated with beneficial effects in prevention of cardiovascular diseases, particularly of atherosclerosis and coronary heart disease. Anti-ageing, antidiabetic and many other health beneficial effects associated with tea consumption are described. Evidence is accumulating that catechins and theaflavins, which are the main polyphenolic compounds of green and black tea, respectively, are responsible for most of the physiological effects of tea. This review describes the evidence from clinical and epidemiological studies in the prevention of chronic diseases like cancer and cardiovascular diseases and inhibits pathogenic bacteria and general health promotion associated with tea consumption.

“…This is particularly true with certain types of cancer, such as ovarian cancer, lung cancer, prostate cancer, colorectal cancer, and bladder cancer. Some studies also show that black tea may help prevent stomach cancer, prostate cancer, breast cancer and oral cancers (especially for those who use tobacco products) [25][26][27][28].…”

This study explains the play of void or the inclusion of various mechanical properties and especially, the sturdiness of different polymers are explained. Impact of interphase around the voids turns out to be more essential and trademark changes in the distortion methodology of nano and micro particles. Minimizing the size of void and distance between the intervoid are the major concern. These techniques are uncovered by many different methods such as modified rubber polymer, nano fiber and nanocomposites. Few nanoscopic toughness methodologies are explained in detail. This study concluded with because of the advantages, nanovoids are selected over microvoids.

“…This is due to the fact that antibiotics derived from materials can prevent resistance to antibiotics developed from chemicals. Tea leaves 8 , Bryonia seabra 9 , flowers extract from Cassia auriculata 10 , Allium Kurrat, and Eruca sativa 11 are some of the natural substances that are commonly used as a source of novel antibiotics, while the antimicrobial from extract of insects are still limited.…”

Antimicrobial activity of black soldier fly larvae extract against gram-positive and gram-negative pathogenic bacteria has been discovered. Water-soluble extracts have the most potential and effectiveness as antimicrobials, with MIC values ranging from 12.5 to 25 mg/mL for both gram-positive and gram-negative bacteria. BSF larvae also create peptides called defensins and cecropins, which have antibacterial properties. Defensins were the best and most effective peptides in inhibiting bacterial growth, inhibiting both gram-positive and gram-negative bacteria (MIC value = > 29.97 µM), while cecropins were more effective on gram-negative bacteria (MIC value= 0.52 – 2.07 µM) than gram-positive bacteria (MIC value not detected).
