A traditional formula for diarrhoea, heat, and digestive upset

Clear Intestine Heat (Ge Gen Qin Lian Tang) is a traditional Chinese herbal formula that supports the body during diarrhoea, digestive heat, and bowel upset with signs of inflammation. First recorded in Shang Han Lun (Discussion of Cold-Induced Disorders) by Zhang Zhong-Jing in the Eastern Han Dynasty, it has long been used when heat and dampness settle in the intestines and disturb normal digestion. It is especially valued when digestive upset comes with foul-smelling stools, abdominal cramping, thirst, or a feeling of heat in the body.

When to use it

In Traditional Chinese Medicine, practitioners choose Clear Intestine Heat when heat and dampness build up in the digestive tract. When this happens, diarrhoea may come on quickly. The stools may smell strong or contain mucus. The abdomen may cramp, burn, or feel unsettled. Some also notice thirst, fever, sweating, or a general feeling of heat.

Many choose this formula for acute diarrhoea, dysentery, gastroenteritis, food-related bowel upset, and other hot digestive patterns. It suits those who want support when digestive symptoms feel intense, inflamed, and disruptive rather than cold or sluggish. The live product page also positions it for abdominal pain, diarrhoea, gastro-enteritis, fever, foul-smelling stools, thirst, and ulcerative colitis.

Why it stands out

What makes Clear Intestine Heat so useful is its focused approach. It does not act as a general digestive formula. Instead, it targets patterns where heat, dampness, and bowel irritation all play a role. This makes it a strong choice for natural support when the bowels feel inflamed, urgent, and out of balance.

Research

Research on Clear Intestine Heat has shown encouraging effects in diarrhoea support, antimicrobial activity, fever reduction, inflammation balance, and bowel recovery. Studies have also explored its relevance in bacterial dysentery, acute diarrhoea, salmonella infection, gastroenteritis, and ulcerative colitis, especially where digestive upset comes with heat and urgency. This gives the formula a strong modern context for short-term digestive complaints that feel hot, intense, and disruptive.
