The primary bioactive compounds in ginger, such as gingerols, shogaols, and Zingerone, play a crucial role in its anti-inflammatory effects. These compounds inhibit key inflammatory mediators and signaling pathways, including nuclear factor kappa B (NF-κB), cyclooxygenase (COX), and lipoxygenase (LOX) pathways. Specifically, ginger has been shown to suppress the production of pro-inflammatory cytokines like interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α) by inhibiting NF-κB activation (Lashgari et al., 2021; Crichton et al., 2023). Additionally, ginger compounds can inhibit the synthesis of prostaglandins and leukotrienes, which are critical in the inflammatory response. These mechanisms collectively contribute to the reduction of inflammation and oxidative stress, making ginger tea a potent anti-inflammatory agent. 2.2 Key studies on ginger tea’s anti-inflammatory effects Several studies have documented the anti-inflammatory effects of ginger tea. For instance, research has shown that ginger extract can significantly reduce inflammatory markers in cellular models of gut inflammation by decreasing levels of IL-6 and IL-8 through NF-κB inhibition (Kim et al., 2017). Another study highlighted ginger's ability to inhibit COX-1 and COX-2 enzymes, which are involved in prostaglandin synthesis, thereby reducing inflammation (Grzanna et al., 2005). In animal models, ginger has demonstrated efficacy in reducing symptoms of inflammatory diseases such as rheumatoid arthritis and ulcerative colitis by modulating inflammatory pathways and cytokine production (Ballester et al., 2022). Furthermore, clinical trials have indicated that ginger can alleviate symptoms of inflammatory conditions like osteoarthritis, showcasing its potential as a therapeutic agent (Haniadka et al., 2013). 2.3 Potential clinical applications The anti-inflammatory properties of ginger tea suggest several potential clinical applications. It could be used as an adjunct therapy for managing chronic inflammatory diseases such as rheumatoid arthritis, inflammatory bowel disease (IBD), and psoriasis. The ability of ginger to inhibit key inflammatory pathways and reduce cytokine production makes it a promising candidate for reducing inflammation and improving patient outcomes in these conditions (Ballester et al., 2022). Additionally, ginger tea may offer benefits in managing acute inflammatory responses, such as those seen in sepsis, by modulating immune responses and protecting against organ failure (Velayati et al., 2023). The gastroprotective effects of ginger also highlight its potential use in preventing and treating gastrointestinal inflammation and related disorders (Bodagh et al., 2018). Overall, the incorporation of ginger tea into clinical practice could provide a natural and effective means of managing inflammation and enhancing patient health. 3 Gastrointestinal Benefits of Ginger Tea 3.1 Ginger tea in alleviating nausea and vomiting Ginger tea has been extensively studied for its efficacy in alleviating nausea and vomiting, particularly in contexts such as pregnancy, chemotherapy, and postoperative recovery. The active compounds in ginger, primarily gingerols and shogaols, have been shown to interact with cholinergic M receptors and serotonergic 5-HT receptors, which play a role in the mechanisms of nausea and vomiting (Giacosa et al., 2015). Clinical trials have demonstrated that ginger can significantly reduce the frequency and severity of nausea and vomiting in pregnant women and chemotherapy patients (Lete and Allué, 2016; Zhang et al., 2020). For instance, a systematic review and meta-analysis found that ginger supplementation reduced the likelihood of acute vomiting by 60% in chemotherapy patients. Additionally, ginger has been found to be effective in reducing postoperative nausea, although its impact on postoperative vomiting is less clear (Lu et al., 2021). 3.2 Role in improving digestion and gut health Ginger tea is also beneficial for improving digestion and overall gut health. The bioactive components of ginger, such as gingerols and shogaols, have been shown to accelerate gastric emptying and stimulate gastric antral
