To detoxify means to remove or neutralize toxins from a person's body, usually referring to removing substances such as alcohol, drugs, or pollutants. This can be done through various methods including fasting, consuming certain foods or drinks, taking medications, or undergoing medical treatments like dialysis. Detoxification is an important process for maintaining good health and well-being, as toxins can accumulate in the body over time and lead to illness or disease if not removed.
