Dachengqi decoction prescription
This prescription is an important prescription for treating cold. There are 19 syndromes in Treatise on Febrile Diseases, which have a wide range of treatment methods, but the focus is on the internal heat syndrome caused by the pathogen of typhoid spreading in Yangming fu-organs, heat entering the interior and dry feces in the intestine. Due to stagnation of excess heat, turbid qi, obstruction of viscera, constipation, frequent occurrence of qi, abdominal distension and pain, internal heat and body fluid, caking of dregs, and dry stool in the intestine, abdominal pain is hard and full, so it is refused to press. Internal heat and evil are strong, disturbing the mind, so see the prophecy. Yang Ming in the limbs is full of qi, the heat in Yang Ming is blazing, and the steaming forces the body fluid to leak out, so the hands and feet sweat. Heat hurts body fluid, which is dry and astringent, so the tongue coating is yellow and dry, even black and prickly, and the pulse is heavy and firm. "Heat-induced lateral flow" is due to excessive internal heat, and dry feces can not be discharged from the intestine, but it is self-cleaning, blue and smelly, and it is hard and lumpy when you see navel and abdominal pain; Burning body fluid with heat is unbearable, so the mouth is dry, the throat is dry and the tongue coating is brown. If the accumulation of excess heat is blocked, the yang is suppressed and the limbs are not reached, the syndrome of heat syncope can be seen; Excessive stomach heat, severe vaginal fluid injury, tendon dystrophy, convulsions, even full chest, inability to lie down, foot convulsions; If the evil heat is disturbed internally, it can be seen that the spirit is faint and even crazy. Although the symptoms of the above syndromes are different, the pathogenesis is the same, which is caused by excessive accumulation of heat in the gastrointestinal tract, excessive heat and great damage to body fluids. At this time, it is appropriate to be eager to save the yin, that is, the method of "rushing to save the yin". In the prescription, rhubarb has the functions of purging heat, relaxing bowels and clearing stomach, which is the monarch medicine. Glauber's salt helps rhubarb to purge heat and relax bowels, and has the effect of softening and moistening dryness. It is a ministerial medicine, and the two medicines must be used together, which has a strong power to calm the heat knot. Internal resistance leads to stagnation of viscera, so Magnolia Officinalis and Fructus Aurantii Immaturus are used to promote qi circulation to disperse stagnation, reduce swelling and swelling, help nitrate yellow heat and promote heat stagnation excretion.
Experimental study on Dachengqi decoction
Length increases gastrointestinal propulsive function and intestinal volume. Tianjin Medical Journal1965 * *10 * *: 790 ~ 791. Dachengqi decoction can obviously increase the gastrointestinal motility of mice after oral administration, and the effect is obvious after 10 minutes. However, in the intravenous administration group, the advancing distance of charcoal powder in the gastrointestinal tract did not increase. Oral Dachengqi decoction can obviously increase intestinal volume.
2. Promote intussusception reduction and relieve obstruction. Tianjin medical journal1965 * *10 * *: 792 ~ 793. The experiment of observing the general mechanism of Dachengqi decoction in relieving intestinal obstruction showed that there were 10 rabbits with artificial intussusception in the administration group. The experiment also believes that the effect of Dachengqi decoction on intestine is mainly regional.
