| 【Pathogenesis】 |
When external cold invasion reaches the interior, it may transform into heat and damage water. The result is the pattern of binding water and heat, which is associated with consumption of yin fluids. The binding of water and heat leads to the disorder of qi transformation and consumption of yin fluids. In this situation they may not ascend and thereby cause dysuria, fever, and thirst with a desire to drink. Yin deficiency with internal heat disturbs the heart and mind to cause vexation and insomnia. If water rushes up to hamper the lung qi and its ability to disperse and descend, cough will manifest. When water accumulates in the stomach, vomiting and nausea will manifest. When water pours into the large intestine, diarrhea will manifest. The red tongue with a white or slightly yellow coating and a thready and rapid pulse are all signs of yin deficiency with internal heat. The therapeutic methods are to promote urination, clear heat, and nourish yin. For patients with dysuria due to blood strangury, the therapeutic principles are to promote urination and relieve strangury, clear heat, and stanch bleeding. |
