Which formula should be utilized for treating LO-1 due to cold?

Utilizing Liang Fu Wan for treating LO-1 due to cold is appropriate because this formula is specifically designed to dispel cold and alleviate pain, particularly in the lower abdomen where cold can disrupt Qi flow. The primary ingredients, including Gao Liang Jiang (Galangal) and Xiang Fu (Cyperus), work synergistically to warm the interior, strengthen the Spleen, and promote movement of Qi. This combination is particularly effective for conditions characterized by cold stagnation, which can lead to symptoms like abdominal pain, diarrhea, and aversion to cold.

In contrast, other formulas such as Ma Zi Ren Wan focus on moving the stool and moistening the intestines but do not specifically address cold-induced issues. Similarly, Qing Qi Hua Tan Tang is primarily used to clear phlegm and heat from the lungs, while Xiao Qing Long Tang is designed to address exterior wind-cold with phlegm accumulation, targeting respiratory conditions rather than gastrointestinal cold patterns. Therefore, Liang Fu Wan is the best choice for treating conditions related to cold in the context of LO-1.
