Stale or moldy garlic may contain a lot of microbial toxic substances, and the toxins may spread to other parts of the garlic that are not visible to the naked eye, which may lead to abdominal pain, diarrhea, dizziness, vomiting, etc. Therefore, yellow spots and dots on garlic should not be consumed in general. Garlic contains minerals and polysaccharides, which are beneficial for long-term consumption for disease prevention. However, some special people cannot consume garlic, such as people with inflammatory lesions or skin breakouts, and it is not recommended to consume garlic while taking anti-inflammatory drugs to avoid the stimulating effect of garlic to aggravate the inflammatory reaction and not conducive to wound healing. If you mistakenly consume garlic with yellow spots and small dots, do not be overly nervous. You can observe whether your body shows symptoms of discomfort, such as nausea, vomiting, abdominal pain, etc. If there is a serious discomfort reaction, it is recommended to seek medical attention in time.
