It is edible. Garlic is also ok. Potatoes cannot germinate. Toxic.

Many places use Jiang Miao to make pickles or something. The sprout is a nutrient in the mother's body, which will germinate when it meets the right temperature and humidity, which is different from the poison of potato bud. The germination of ginger is similar to that of garlic, but the nutrition is absorbed by the bud and the mother body contracts, so the taste, taste and fragrance are not as good as that of garlic.

When the ginger is cut open, it can be found that the meat inside is dried and the fiber becomes thicker, indicating that the nutritional components of ginger have begun to decrease and the nutritional value has decreased, but the main components have not been destroyed.

In fact, most ginger in the market has buds, but it is not obvious. However, if ginger is not properly preserved after germination, it will cause growth dormancy, begin to rot and breed bacteria. If you eat it at this time, you will have diarrhea.

There is a folk saying that "rotten ginger doesn't taste bad", which means rotten Jiang Ye can be eaten, but it is actually wrong.

Rotten ginger contains safrole, which may cause degeneration and necrosis of liver cells, thus inducing liver cancer, so it is absolutely inedible. Just put the ginger and garlic in a plastic bag, and then seal the mouth of the plastic bag tightly, so that the carbon dioxide released by the ginger and garlic in the bag can not be emitted, and at the same time, it also blocks the entry of water, so that the ginger and garlic are in a suitable dormant state, which can prevent rot.
