Answer. Nipple stimulation can be used to make the uterus cramp. This is useful after the baby is born to help the placenta separate from the uterus, or after the placenta is delivered to help the uterus contract and decrease postpartum bleeding.
A pineapple allergy occurs when the body&#039;s immune system reacts to something in the pineapple that it considers harmful. The immune system produces both an antibody and histamine, a combination that can cause symptoms ranging from anaphylaxis to asthma, abdominal distress, eczema or headaches.
Best Answer: Fresh pineapples contain a special protease and 5-hydroxyptamine. The latter makes blood vessels (especially those in the brain) shrink, and may cause headaches and a rise in blood pressure. That is why some people experience headaches after eating too much fresh pineapple. Some people are even allergic to pineapple; after eating only a little, their skin may turn red and itch, and their limbs, mouth and lips become numb. They may also feel bilious and vomit, or develop severe stomach aches.
