The color of stool is affected by many factors. Black stool may be related to disease and diet, and is usually not a detoxification phenomenon. The color of stool may be related to the type of food and the medication taken. Many herbal medicines themselves are darker in color, such as charcoal and thorn charcoal medicines, and the color of stool will be darker after taking the medicine. Consumption of some foods such as animal liver, etc., also tend to cause dark stools. Black stools may also be caused by gastrointestinal bleeding, so never equate black stools with detoxification. If it is only temporary, it may be caused by food, but if it is long-term, it may be due to your own disease and you need to seek medical attention as soon as possible. In daily life must pay attention to the habit of regular bowel movements, to drink more water, do not eat laxatives or detoxification drugs for detoxification, to prevent dependence on drugs.
