Gelatin is a solid and transparent material that has wide application in various industries, especially for the production of food and pharmaceutical. This material is mainly made from meat, skin and bones of pigs and cows around the world. The industrial process of gelatin production is a long and costly process Also; these sources of gelatin production are prohibited in many religions and cultures in the world and they have a lot of health hazards. Therefore, this study was aimed at reviewing the alternative sources of gelatin production and the disadvantages and benefits of each of them. Relevant articles were searched from Google Scholar, PubMed, Scopus, Science direct, and Cochrane library. According to the results of this article, gelatin with a source of animal can have many harmful effects on human health. While it is possible to produce good and useful gelatin using plant sources. Almighty Allah has always recommended humans to consume halal foods while avoiding haram foods. Extensive research is required from the Islamic world to replace haram products with halal and Islamic products. Nowadays, from materials such as agar, pectin, carrageenan and konjac that are mentioned above, and as well as other materials, very good gelatins are prepared. And further researches are needed to find the rich sources of good gelatins or to find plants that have appropriate gelatin.

Genetic modification is a specific part of gene technology that changes the genetic structure of living organisms, such as animals, plants, or microorganisms. Genetically Modified, is known with such names as Transgenic or Transgenic. In recent years, discussions have arisen about the potential effects of transgenic corn on health There are also discussions about its effect on other insects and other plants due to the gene flow The study was conducted as a systematic double-blind review by searching the Internet at the Google Scholar, PubMed, Science Direct, Medline, Highwire, MD Consult and Scopus databases. From the result of this study, we can come to a Conclusion that any transgenic product is not usable and can have many disadvantages, while some of them are completely safe and usable.

Background: There are many coronaviruses, which can cause diseases in humans and animals. The new 2019 coronavirus is highly prevalent and contagious, infecting many people in almost all countries of the world. There are many problems involved in the treatment of COVID-19 that must be discussed and examined. Research Methods: A systematic review was conducted on double-blind studies found on such online databases as Google Scholar, PubMed, Science Direct, Medline, Highwire, MD Consult, and Scopus by Internet-based search. Results and Conclusions: Many deaths attributed to COVID-19 are caused by mistakes made in the prescription of medications, leading to the deterioration of the conditions of the patients, the most serious of which is the prescription of corticoids. Additionally, it has not been properly researched whether some drugs such as NSAIDs are indicated for use in COVID-19 or not. On the other hand, the application of some valuable medicinal herbs, such as peppermint and chamomile, in the treatment of this disease has not received enough attention, despite the fact that they may have valuable and remarkable effects in the treatment of this disease.

Background: Fatty acid is a type of carboxylic acid with carbon chain that can be short (4 carbons, such as butyric acid) or long (14 carbons and more, like DHA). Generally, fatty acids are divided into two groups of unsaturated fatty acids and saturated fatty acids. They have important and valuable medicinal properties especially against microbial pathogens. Objective: Studies have shown that the epidemic of the twentieth century's heart disease is due to the abuse of trans fatty acids. The consumption of various fatty acids has various therapeutic effects on various diseases. Method: Relevant articles were searched from Google Scholar, Pub Med, Scopus, Science direct, and Cochrane library. Results: Getting omega-3 fatty acids through diet and supplements affects both acute and chronic inflammation. Consumption of omega-3 fatty acids can slow down the growth of cancer, increase the effect of chemotherapy and reduce the side effects of chemotherapy or cancer. This can be done by reducing angiogenesis in the tumor, creating the differentiation of cancer cells, reducing the risk of heart attack from cancer, etc. Conclusion: In general, fatty acids are valuable and affordable, and available with numerous medicinal properties, including anti-fungal and anti-bacterial properties that can be extracted from and used by many sources, especially many medicinal plants. Since antimicrobial chemicals generally have many side effects and have resistance to many microbial species, various studies and experiments to identify and extract fatty acids and their application to the title of the pharmaceutical formulation are essential.
