【Indication】 |
This formula is indicated for yin summerheat. The symptoms are aversion to cold with fever, heaviness of the head, body pain, absence of sweating, abdominal pain, vomiting and diarrhea, chest and abdominal oppression and fullness, a greasy white tongue coating, and a floating pulse. |
【Pathogenesis】 |
This formula is commonly used in patients who have exterior cold and internal dampness after taking too much cold drinks or have been exposed in a cool environment for too long during the summer. In summer people usually prefer cold drinks and staying in a cool environment, yet the striae and interstices are often loose. As a result, people are apt to contract cold and dampness. Cold-dampness constrains the exterior, the striae and interstices, and blocks the wei yang. This causes an aversion to cold with fever, absence of sweating, and a floating pulse. Cold-dampness constrains the fleshy exterior and obstructs qi and blood, causing heaviness of the head and body pain. Having too much cold food and drinks during the summer damages the spleen and stomach and inhibits qi movement, which causes chest and abdominal oppression and fullness, and abdominal pain. Dampness encumbers the spleen and stomach and causes their ascending and descending functions to become irregular. This manifests as vomiting caused by the ascending counterflow stomach qi, and diarrhea caused by dampness pouring down to the large intestine. The greasy white tongue coating is a sign of cold-dampness. The therapeutic method is to release cold-dampness from the fleshy exterior, and drain the dampness encumbering the spleen and stomach. |
