Folk remedies have long proposed that ginger tea may ease symptoms of motion sickness, including dizziness, vomiting and cold sweats.
Clinical evaluation conducted in 2020 indicated a possible connection between ginger intake and relief from motion sickness, though additional research remains necessary to confirm its efficacy.
The precise mechanism behind ginger’s effect is not yet fully understood. Some researchers propose that certain compounds in ginger may block a receptor in the brain associated with the vomiting centre. Despite this theory, current scientific evidence remains limited and inconclusive.
Nevertheless, ginger tea may serve as a simple treatment option for occasional nausea.
Ginger and Nausea Relief in Specific Contexts
Gingerols, active compounds in ginger, are thought to alleviate nausea related to chemotherapy or surgery. Research has suggested that ginger may serve as an effective and low-cost alternative to anti-nausea medication in cases where standard treatment is unsuitable.
In a study involving 92 women, ginger was reported to outperform conventional medicine in preventing postoperative nausea and vomiting following general anaesthesia. However, medical consultation is advised prior to use after surgery, as ginger may affect blood clotting, although further evidence is required to substantiate this concern.
Possible cardiovascular support
Daily consumption of 2–6 grams of ginger may assist in the prevention of heart disease. Research indicates ginger may contribute to cardiovascular health through various mechanisms.
Potential effects on weight and blood sugar management
A growing body of research supports the role of ginger in regulating body weight and blood glucose levels.
In individuals with type 2 diabetes and obesity, ginger has been associated with improvements in fasting insulin levels, haemoglobin A1C and triglycerides. Haemoglobin A1C reflects average blood glucose levels over two to three months.
Relief from pain and inflammation
Ginger has historically been used to treat inflammation, a practice now supported by scientific studies. Compounds such as gingerol and shogaol are known to reduce pro-inflammatory markers.
In particular, ginger has been examined for its effectiveness in relieving knee osteoarthritis pain, often in combination with turmeric and black pepper.
Potential anti-cancer properties
Preliminary research has explored the anti-cancer potential of ginger derivatives. 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, colorectal, ovarian, prostate and lung cancers. Human trials, however, remain limited, and more clinical research is required to determine effectiveness.
Neuroprotective possibilities
Research has explored the protective properties of ginger against oxidative stress and inflammation, both implicated in neurodegenerative diseases such as Alzheimer’s. Animal studies suggest gingerol and shogaol may slow age-related cognitive decline due to their antioxidant capabilities.
Further laboratory findings indicate that ginger extract may protect brain cells from damage linked to beta-amyloid, a protein associated with Alzheimer’s disease.
