Indication
1. Pattern of yang constraint and reversal counterflow cold of the limbs, marked by a lack of warmth in the extremities, abdominal pain, diarrhea, dysentery tenesmus, and a wiry pulse.
Pathogenesis
Originally Si Ni San is used to treat “counterflow cold of the four limbs in a shaoyin pattern”. Counterflow cold of the four limbs here actually refers to a lack of warmth in the extremities. When the exterior pathogen invades the internal body via the channels, constraint and stagnation of the qi movement occurs. Disordered qi flow causes yang qi constraint, which results in a lack of warmth in the extremities. Later doctors broadened its scope by using it for distention and fullness in the rib-side, and pain in the stomach cavity and abdomen due to liver and spleen constraint and stagnation. The treatment is to move qi, resolve constraint, soothe the liver, and rectify the spleen.
Application
1. Essential pattern differentiation Si Ni San treats the patterns of yang constraint and reversal counterflow cold of the limbs, which is its original indication. However, later doctors use it as a basic formula to soothe the liver and rectify the spleen. This clinical pattern is marked by lack of warmth in the extremities, pain in the rib-side, stomach cavity, and abdomen, and a wiry pulse. 2. Modern applications This formula may be used in the following biomedically defined disorders when the patient shows signs of qi constraint of liver and gallbladder, liver-spleen disharmony, or liver-stomach disharmony: chronic hepatitis, cholecystitis, cholelithiasis, biliary ascariasis, intercostal neuralgia, ulcers, gastritis, gastrointestinal neurosis, annex inflammation, tubal obstruction, and acute mastitis.
