For centuries, folk remedies have suggested that ginger tea can help alleviate symptoms of motion sickness, including dizziness, vomiting, and cold sweats. Clinical studies conducted in 2020 indicated a possible link between ginger consumption and relief from motion sickness, although more research is needed to confirm its effectiveness.
The exact way ginger works is not yet fully understood. Some researchers hypothesize that certain compounds in ginger may block a receptor in the brain linked to the vomiting center. Despite this theory, current scientific evidence is limited and not conclusive. Nonetheless, ginger tea can be a simple remedy for occasional nausea.
Ginger and Nausea Relief in Specific Contexts
Gingerols, the active compounds in ginger, are believed to alleviate nausea associated with chemotherapy or surgery. Research has suggested that ginger could be an effective and low-cost alternative to anti-nausea medication in cases where standard treatment is not suitable.
In a study of 92 women, ginger was found to be more effective than conventional medicine at preventing postoperative nausea and vomiting after general anesthesia. However, it’s recommended to consult a doctor before using ginger after surgery, as it may affect blood clotting, although more evidence is required to fully substantiate this concern.
Cardiovascular Support
Daily intake of 2–6 grams of ginger may assist in the prevention of heart disease. Research indicates that ginger may contribute to cardiovascular health through various mechanisms.
Effects on Weight and Blood Sugar Management
A growing body of research supports ginger’s role in regulating body weight and blood glucose levels. In individuals with type 2 diabetes and obesity, ginger has been linked to improvements in fasting insulin levels, hemoglobin A1C (which reflects average blood sugar over two to three months), and triglycerides.
Relief from Pain and Inflammation
Ginger has been historically used to treat inflammation, a practice now supported by scientific studies. Compounds like gingerol and shogaol are known to reduce pro-inflammatory markers. In particular, ginger has been examined for its effectiveness in relieving pain from knee osteoarthritis, often in combination with turmeric and black pepper.
Potential Anti-Cancer Properties
Preliminary research has explored the anti-cancer potential of ginger compounds. Laboratory studies have shown that gingerol and shogaol may suppress the growth and reproduction of cancer cells by inducing cell death. These compounds have been studied in relation to several cancer types, including pancreatic, colon, ovarian, prostate, and lung cancers. However, human trials are still limited, and more clinical research is needed to determine their effectiveness.
Neuroprotective Possibilities
Research has explored ginger’s protective properties against oxidative stress and inflammation, both of which are implicated in neurodegenerative diseases like Alzheimer’s. Animal studies suggest that gingerol and shogaol may slow age-related cognitive decline due to their antioxidant capabilities. Further lab findings indicate that ginger extract may protect brain cells from damage linked to beta-amyloid, a protein associated with Alzheimer’s disease.
