Which formula is typically used for constipation due to LI Heat Obstruction?

The formula that is typically used for constipation due to Large Intestine Heat Obstruction is Tiao Wei Cheng Qi Tang. This formula is specifically designed to address excess heat in the large intestine, which manifest as constipation. The symptoms associated with this condition often include hard stools, dry mouth, and possibly fever, indicating a presence of heat in the body.

Tiao Wei Cheng Qi Tang contains ingredients that help to clear the heat and promote bowel movements. It is primarily used when there is a significant obstruction due to heat, making it especially suitable for constipation linked with these symptoms. The components of the formula work synergistically to purge heat from the intestines, thus facilitating smoother passage of stools.

The other formulas mentioned are used for different conditions. For instance, Ma Zi Ren Wan is often used for constipation due to dryness, particularly when there is less emphasis on heat and more on deficiency of lubrication. Liang Fu Wan focuses on addressing conditions related to cold and stagnation affecting the middle burner, and Xiao Qing Long Tang is primarily applied in cases of cold with phlegm. Therefore, understanding the specific nature of the underlying problem is essential for selecting the appropriate herbal formula in traditional Chinese medicine.
