Magnesium sulfate can solve constipation, but also from the intestinal absorption function. The intestinal tract has two main ways of absorbing digested ingredients:
One is passive osmosis, such as water, glucose, salt, etc.
The other is active absorption, which is selective. Magnesium ions are an electrolyte, which belongs to the latter. If the dose in the intestinal tract is large, in order to maintain the balance of intestinal osmotic pressure, water will be sucked from the body to the intestinal tract, so that the water in the intestinal tract will increase, and the water will reach the intestinal tract with constipation, which can soften the dry and hard Fecal balls, which lubricate the bowel. In this way, if there is a defecation reflex, the stool can be easily discharged.
Note: Magnesium sulfate is a highly irritating drug, use it with caution, excessive use can cause miscarriage.
Researchers once used magnesium sulfate to test a big boar. Because of the inconvenience of feeding the medicine, they first closed the valve of the free drinking fountain, and put a drinking bucket in the pigsty, which contained a prepared magnesium sulfate solution. Then guide the pigs to drink the liquid medicine. After the pigs drink a certain amount, then open the water valve to let the pigs drink the water. Later, the boar soon defecated and the constipation problem was resolved
