Experimental Study Anti-Inflammatory Ginger Wound Healing
The study utilised the solid-liquid extraction method to obtain phenolic extracts from turmeric and ginger rhizomes. Using Wistar rats as a biological model, the researchers examined the anti-inflammatory effects of the extracts by observing the decrease in edema volume in the rat's hind paw following treatment. Moreover, the healing process of purposefully induced burns on the rat's dorsal region was monitored to evaluate the healing activity.
In the discussion of the results, it was observed that the application of creams containing the mentioned extracts resulted in complete healing after 19 days, a marked improvement compared to the control group, which only achieved 60% healing. The extracts demonstrated different levels regarding tissue repair at day 14, showing their respective potency. The study also identified diverse molecular weight distribution of phenolic compounds within the extracts, suggesting potential influence on how they affect anti-inflammatory and wound healing activities.

A Systematic Review published in 2022 in the journal Iranian Journal of Public Health found that The application of curcumin and turmeric, due to their anti-inflammatory effects, can alleviate symptoms and improve the quality of life in people with irritable bowel syndrome. The research was conducted by conducting a systematic review of all available evidence regarding the therapeutic potential of curcumin and turmeric for relief from irritable bowel syndrome symptoms.

A Randomised Controlled Trial published in 2021 in the journal Phytotherapy Research found that Curcumin supplements have comparable effects to placebos in alleviating symptoms of Premenstrual Syndrome and dysmenorrhea in young women. In the methodology of this study, a randomized, triple-blinded, placebo-controlled trial was carried out. Women who were affected by both Premenstrual Syndrome and dysmenorrhea were enrolled and randomly assigned to either the curcumin or placebo group. Participants were given a capsule, containing either 500mg of curcuminoid or a placebo, once daily, starting from 7 days before menstruation and continuing till three days after menstruation. This was maintained for three continuous menstrual cycles. As per the results, upon the completion of the trial, both the curcumin and placebo groups witnessed a significant decrease in the severity of Premenstrual Syndrome and dysmenorrhea symptoms, as evident by a decrease in the scores of the Premenstrual Syndrome Screening Tool and the visual analog scale. Therefore, curcumin was found to have similar effects to the placebo, in terms of relieving symptoms of both Premenstrual Syndrome and dysmenorrhea.
A Review Article published in 2021 in the journal Journal of the Science of Food and Agriculture found that Curcumin, derived from turmeric, exhibits an extensive range of biological and medicinal properties, including anti-inflammatory, antioxidant, and antifungal qualities. The research examines turmeric extracts, specifically focusing on curcumin, a yellow biocomponent. An array of its medicinal and biological properties is explored, particularly anti-inflammatory, antioxidant, and antifungal attributes. Traditionally used in various cultures for a range of health issues like inflammation, cough, wounds, liver disorders, and cancers, curcumin's extensive application in treating a variety of diseases potentially positions it as a significant component in modern medicine. The study also notes the successful tolerance of curcumin at high doses with no adverse effects. The analysis extends to the preferred methods for the encapsulation of curcumin, detailing techniques such as nanocomplexing, gelation, complex coacervation, electrospraying, and solvent-free pH-driven encapsulation. These methods have demonstrated effectiveness in encapsulating curcuminoids. Moreover, the chemical traits of curcumin are also highlighted, providing a basis for further potential applications in the development of health-promoting functional products.
A Review Article published in 2021 in the journal Clinical Ophthalmology found that Curcumin, with its anti-inflammatory, antioxidant, antimicrobial and antimutagenic properties, is a potential therapeutic agent for retinal diseases. This review paper uses various pieces of research from the literature to detail the characteristics of curcumin, a molecule produced by plants. The paper particularly focuses on the beneficial and controversial aspects of curcumin. It talks about the retina's susceptibility to oxidative stress due to its cell composition and constant exposure to photons, highlighting that retinal ganglion cells and photoreceptors are particularly sensitive to oxidative damage. The paper also points to studies that link an imbalance in reactive oxygen species to a wide range of retinal diseases. In the discussion of results, it is stated that a number of studies suggest that curcumin can be well tolerated by humans when taken orally and does not tend to have negative effects, making it a promising candidate for retinal disease treatment. However, a primary limitation is curcumin's poor bioavailability; the body can only absorb a small fraction of the substance as an active compound. Despite that, efforts have been made to improve curcumin's accessibility to target tissues in sufficient quantities.
A Systematic Review published in 2021 in the journal Nutrition, Metabolism and Cardiovascular Diseases found that Consumption of certain foods like rapeseed/canola oil, avocados, and turmeric can lead to moderate to large reductions in LDL cholesterol levels. The research was carried out by conducting a systematic evaluation of existing guidelines, systematic reviews, and Randomised Control Trials (RCTs); we have only referred to the latter for studies on coffee intake. This was done on databases such as PubMed, Cochrane Database of Systematic Reviews, and Cochrane Central Register of Controlled Trials, alongside a search on the Trip database for guidelines. The time frame for the study was from its inception up until June 2019 and October 2019 respectively. Studies were included if they were at least 13 days in duration and were in English. Using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) method, 37 guidelines, 108 systematic reviews, and 20 RCTs were evaluated to analyze the strength of evidence in the context of food impacts on LDL cholesterol levels. The results of the research reveal that foods high in unsaturated and low in saturated and trans fatty acids such as rapeseed or canola oil, those with added plant sterols/stanols, and those high in soluble fibre like oats, barley and psyllium cause moderate reductions in LDL cholesterol. A moderate to a large increase was observed with unfiltered coffee though. Soy protein, tomatoes, flaxseeds, and almonds cause small reductions. Meanwhile, foods like avocados and turmeric cause moderate to large reductions with a moderate level of evidence supporting this observation. Other foods like pulses, hazelnuts, walnuts, high-fiber/wholegrain foods, green tea result in small to moderate reductions, and sugar causes a small increase. Several foods identified were either neutral or had low or very low evidence regarding their effects on LDL cholesterol levels.
A Review Article published in 2021 in the journal Molecules found that Green tea, coffee, wine, and curry have beneficial health effects due to the polyphenols they contain, which possess both antioxidant and pro-oxidant properties. The research leverages epidemiological studies, clinical trials, cell-based studies and animal tests to examine the effects of green tea, coffee, wine, and curry -- and their key polyphenols -- on human health. The polyphenols investigated include epigallocatechin gallate in green tea, chlorogenic acid in coffee, resveratrol in wine, and curcumin in curry. The study concentrates on the workings of these polyphenols, primarily focusing on reactive oxygen species (ROS), and how they perform both anti- and pro-oxidant functions, fundamentally influencing different enzymes and factors with health contributions. In the discussion of the results, it is mentioned that the anti-oxidative actions of these polyphenols assist in the scavenging of ROS and the downregulation of the nuclear factor-κB, yielding beneficial anti-inflammatory effects. Conversely, their pro-oxidant actions appear to elevate ROS production, encouraging the activation of 5'-AMP-activated protein kinase that regulates different enzymes and factors for health improvement. However, the exact mechanism of how these polyphenols exhibit either pro- or anti-oxidant effects remains unclear. Also, the research underscores that while many studies note their health benefits, some others show no positive effects on health conditions such as obesity, suggesting that outcomes could be influenced by various study factors.
A Animal Study published in 2017 in the journal Holistic Nursing Practice found that Curcumin's potential anxiolytic and antidepressant impacts do not significantly alter behavior or interact with the benzodiazepine site of the gamma-aminobutyric acid receptor A. In this study, a prospective, between-subjects group design was employed. The subjects were 55 male Sprague-Dawley rats randomly split into five groups, each given different intraperitoneal injections: a control group, curcumin, curcumin with flumazenil, midazolam alone, and midazolam with curcumin. Behavioral observations were conducted with the aid of the elevated plus maze, open field test, and forced swim tests. A two-tail multivariate analysis of variance was deployed for data analysis. The results showed that, according to the behavioral tests, curcumin did not generate any notable signs of anxiety-relieving or mood-lifting effects. It was also noticed that curcumin didn't show any interactive tendencies with the GABAA receptor's benzodiazepine site. The team therefore concluded that curcumin didn't produce any significant outcomes on these aspects of mental health modulation as was purposed in the initial hypothesis.
A Review Article published in 2012 in the journal Journal of Psychopharmacology found that Curcumin, a component of Indian spice turmeric, presents a potential natural treatment for depression, influencing neurotransmitters and protecting against several biological systems compromised in depression. The research methodology involved an extensive review of the varying influences and effects of curcumin on systems implicated in depression. These included neurotransmitter systems like serotonin and dopamine which are critical to mood regulation. The study also explored the effects of curcumin on hypothalamus-pituitary-adrenal disturbances, famously associated with stress response and mood disorders. In terms of results, curcumin demonstrated promising potential as an antidepressant in animal models of depression. Additionally, it was found to help moderate damage to neurological systems and intestinal permeability, both of which are often compromised in major depressive disorders. It also exhibited properties that could help lower inflammation and protect against oxidative stress and mitochondrial damage. Together, these findings position curcumin as a promising natural treatment for depression.
