Ginger is not only a cooking spice but also an important ingredient and is widely used in Oriental medicine.

According to Oriental medicine, fresh ginger has a spicy taste, slightly warm properties, and targets the three meridians of the lungs, spleen, and stomach; it has the effect of dispelling cold, warming the middle, reducing phlegm, and promoting water and detoxification. Due to these effects, fresh ginger reduces the symptoms of wind-cold and flu. When the weather gradually turns cold, you can take a few slices of crushed ginger and drink the juice, or put it in warm tea to dispel cold and reduce cough.

In some studies, ginger has antibacterial, anti-inflammatory, and anti-cancer properties. Ginger has been studied for its effects on digestive disorders, arthritis, cancer, and various factors related to cardiovascular health. The antiemetic (reducing nausea) effect of ginger may be beneficial for pregnant women, motion sickness, and post-anesthesia women. Fresh ginger contains gingerol, which stimulates the intestinal mucosa and increases appetite.

However, using ginger for people with the following diseases will cause serious harm to health.

5 groups of people should not eat ginger:

- People with liver disease

One of the effects of ginger on healthy people is to prevent fatty liver disease. However, for people with liver disease, ginger is a taboo food. The reason is that the hot and spicy nature of ginger will stimulate secretion in damaged liver cells, leading to stimulation of liver cells, making them susceptible to necrosis. Therefore, people with liver disease are also on the list of people who should not drink ginger tea.

- People with stomach and duodenal diseases

For people with stomach diseases such as stomach pain, stomach ulcers, they should not use too much ginger. Absorbing large amounts of ginger for these patients can irritate and erode the stomach lining, making ulcers worse, leading to increasingly serious illness.
