Eating too much garlic also has side effects:

1. Garlic can increase gastric acid secretion and capsaicin can stimulate gastric acid secretion, so people with gastrointestinal diseases, especially gastric ulcer and duodenal ulcer, should not eat garlic. Patients with liver disease should not eat more garlic, which may cause liver dysfunction. Although garlic has a protective effect on the liver, it has no effect on hepatitis virus, but it will stimulate the gastrointestinal tract and inhibit the secretion of digestive juice, thus aggravating the symptoms of hepatitis patients such as nausea.

2, excessive consumption of garlic will affect vision. Chinese medicine believes that eating garlic in large quantities for a long time will "hurt the liver and hurt the eyes", so patients with eye diseases should be cautious when eating garlic. In particular, patients with poor health and weak qi and blood should pay more attention, otherwise, after a long time, vision loss, tinnitus, top-heavy and memory loss will occur.

People who are not suitable for eating garlic:

1, garlic should not be eaten raw in cases of non-bacterial enteritis and diarrhea. Because the pungent allicin in raw garlic can stimulate the intestine, make the congestion and edema of intestinal mucosa worse, promote exudation and aggravate the condition. If diarrhea has occurred, garlic should be eaten with caution.

2. Patients with lung and stomach fever, dizziness due to blood deficiency and body odor should not eat garlic.

3. Severe patients with other diseases. Eating spicy food such as garlic and pepper is good for healthy people to stay healthy for a long time, but it has obvious side effects on patients who are seriously ill or taking medicine, which not only makes the medicine ineffective, but also may have a chain reaction with the medicine, making patients dangerous.
