Black garlic generally does not harm the liver, but it should be consumed in moderation.

Black garlic is a common food rich in nutrients such as protein, carbohydrates, and vitamins; moderate consumption helps replenish the body’s nutritional needs. It contains abundant allicin—a natural antibiotic with anti-inflammatory and bactericidal properties—which can aid in treating conditions like bacterial dysentery and acute gastroenteritis.
Additionally, the vitamins and minerals in black garlic promote gastrointestinal motility, aiding digestion and helping to alleviate constipation. However, due to its high allicin content, excessive consumption may irritate the gastrointestinal tract, causing discomfort such as abdominal pain and diarrhea; therefore, it should be eaten in moderation.
The liver is a vital metabolic organ; liver dysfunction can impair the body’s metabolic processes, preventing the absorption of nutrients from food and potentially leading to malnutrition. Patients are advised to seek medical attention promptly and may undergo treatment with medications such as Compound Glycyrrhizin Tablets or Bicyclol Tablets under a doctor’s guidance. Adjunctive therapies, such as acupuncture and cupping, may also be used under professional supervision.
