Dan dou chi is a Chinese herb commonly used in traditional Chinese medicine (TCM) and cooking. It is also known as fermented soybean, soybean ferment, or Praeparatum Semen Sojae Germinatum in Latin. Dan dou chi is made by fermenting soybeans with the bacteria Bacillus subtilis. Here are a few ways Dan dou chi is used:

  • In Traditional Chinese Medicine: Dan dou chi is used in TCM to promote digestion, reduce bloating and gas, and calm the mind. It is often combined with other herbs in herbal formulas.

  • In Cooking: Dan dou chi has a salty, slightly sour flavor and is commonly used in soups and stews in Chinese cuisine. It can also be added to stir-fries, marinades, and dressings for extra flavor.

  • As a Health Supplement: Dan dou chi is sometimes taken as a health supplement to promote gut health, reduce inflammation, and support the immune system. It is available in supplement form as well as in dried or canned form for cooking.



  • Promotes Digestion: Dan dou chi is often used in Traditional Chinese Medicine to promote digestion and relieve bloating and gas. It is believed to stimulate the production of digestive enzymes, which can help break down food and improve nutrient absorption. Dan dou chi is also believed to have a prebiotic effect, meaning it can feed the good bacteria in the gut and support a healthy gut microbiome.

  • Anti-Inflammatory Properties: Dan dou chi contains compounds such as isoflavones, which have been shown to have anti-inflammatory properties. This makes it a potential natural remedy for inflammatory conditions such as arthritis, asthma, and eczema. Dan dou chi is also believed to have antioxidant properties, which can help protect the body from oxidative stress and cellular damage.

  • Calming Effect: Dan dou chi is believed to have a calming effect on the mind and is often used in TCM to promote relaxation and reduce stress. This effect is thought to be due to the presence of GABA, a neurotransmitter that can help regulate mood and promote a sense of calmness. Dan dou chi is also believed to have a sedative effect, which can help promote restful sleep.



  • Prepared soybean contains vitamin K2, which can interfere with blood thinners such as warfarin, increasing the risk of bleeding. People taking blood thinners should talk to their healthcare provider before consuming prepared soybean.

  • Soybean is a common allergen, and people with soybean allergies should avoid consuming prepared soybean.

  • Prepared soybean contains a compound called tyramine, which can cause headaches or migraines in some people, particularly those with a history of migraine or who are taking certain medications.

  • Some people may experience gastrointestinal symptoms, such as gas or bloating, after consuming prepared soybean.

  • The safety of consuming prepared soybean during pregnancy and breastfeeding has not been fully studied, and it is best to consult with a healthcare provider before consuming it during these times.
