Introduction: Chamomile (Matricaria chamomilla L.), as widely used as a medicinal herb and is brewed beverages, and has been used for the treatment of several conditions. The evidence from in vitro, in vivo, and clinical studies suggests that chamomile and its many flavonoid components have anti-oxidant and anti-inflammatory properties. This review aimed to provide an overview of the chemical constituents of chamomile and the effectiveness of the chamomile preparations and several of its constituents for the treatment of several medical conditions. Methods: The present comprehensive review study was conducted by searching electronic databases including Scopus, Web of Sciences, Embase, and PubMed, using relevant keywords. Results: Both animal and human studies indicate the positive effects of chamomile on the antioxidant enzyme activity. However, the mechanisms involved in the action of chamomile against the production of ROS remain still unknown. When it comes to its anti-inflammatory properties, a number of in vitro, in vivo, and clinical investigations have been reported regarding to the selective inhibition of COX-2, suppression of NO production, prevention of IL-1β, IL-6 and TNFα-induced NO levels, reduction of iNOS mRNA and protein expression, impediment of leukocyte adhesion and adhesion protein up-regulation in human endothelial cells, and blockage of IL-1 α-induced prostaglandin production, TNF-α-induced IL-6 and IL-8 release. Conclusions: Current studies suggest that chamomile and its flavonoid components have anti-oxidant and anti-inflammatory properties. On the basis of the existing evidences, chamomile appears to ameliorate several diseases caused by oxidative stress as well as inflammatory reactions.

Acute respiratory Syndrome (SARS) is an uncommon respiratory illness that is transmitted primarily by respiratory droplets or direct contact with an infected person. The COVID-19 initially appeared in late 2019 in Wuhan, China, and spread everywhere around the globe. Earlier in 2003, the coronavirus was known due to the human SARS-CoV virus, which infected 8,000 people and caused 800 deaths in southeast Asia and Canada. It should be mentioned that in 2012, another coronavirus, called Middle East respiratory syndrome coronavirus, infected Saudi Arabia and 27 other countries. The SARS-CoV2 belongs to a family of viruses called Coronaviruses that can infect bats, birds, pigs, cows, and different mammals. Some plant extracts are shown to inhibit microorganism replication and may be utilized in medication to treat infectious and non-infectious diseases, one of which is chamomile. chamomile medicinal plant, that has 120 biologically active compounds, the most necessary of which are flavonoids, like apigenin and luteolin, that are shown to possess antiviral activity.

Curcumin (diferuloylmethane) is a yellow, active substance of an herbal origin, which is mainly derived from turmeric of the ginger family. Extensive research has been focused on the therapeutic effects of this substance on diabetes, cancer, and cardiovascular diseases, and the hepatoprotective properties have attracted the attention of researchers. In addition, curcumin significantly improves oxidative stress, mitochondrial dysfunction, and inflammation. It could also modulate various cell signals in cytokines, chemokines, growth factors, and enzymes. Curcumin attenuates the blood glucose by increasing insulin levels. According to findings, consuming one gram of curcumin per day for one month could decrease total cholesterol, low-density lipoprotein cholesterol, triglyceride, and high-density lipoprotein cholesterol. Moreover, it contributes to the control of some of the main parameters associated with the metabolic syndrome, which is an important risk factor for cardiovascular diseases. Hepatic cholesterol metabolism is also regulated by curcumin, which has a similar function to lovastatin in the long run. Curcumin has been reported to prevent the enlargement of solid tumours. Several have confirmed the therapeutic role of curcumin in the management of the metabolic syndromes and cardiovascular diseases. The present study aimed to review the therapeutic effects of curcumin.
