| 【Method】 |
Prepare Da Qin Jiao Tang as a decoction for oral use with an appropriate reduction in dosage. |
| 【Action】 |
Scatters wind and clears heat, nourishes and invigorates blood. |
| 【Indication】 |
Da Qin Jiao Tang is indicated for an early stage of a wind attacking the channels and collaterals pattern. The symptoms are deviation of the eyes and mouth, difficulty in speaking due to stiff tongue, an inability to move the extremities, often accompanied by aversion to cold with fever, spasms and tension of the extremities, a white or yellow tongue coating, and a superficial, rapid pulse or wiry, thin pulse. |
| 【Pathogenesis】 |
This formula treats wind-strike caused by wind pathogens striking the channels and collaterals. When wind strikes a person with insufficient zheng qi and deficiency of the ying-blood and channels, it leads to obstruction of qi and blood and blockage of channels. In addition, insufficient blood fails to nourish the sinews causing atrophy and weakness of the sinews and muscles. The result is deviation of the eyes and mouth, difficulty in speaking due to a stiff tongue, and an inability to move the extremities. Invasion of the exterior by pathogenic wind manifests an aversion to cold, fever, and a floating pulse. The primary treatment is to dispel wind and scatter pathogens, along with nourishing and invigorating blood to unblock the collaterals. |
