Symbolic proportion is when you use another item to explain what something is to someone. For example, you might tell someone an old Nintendo game looked like an 8-track tape.
Mineral oil is used to treat constipation. It is known as a lubricant laxative. It works by keeping water in the stool and intestines. This helps to soften the stool and also makes it easier for stool to pass through the intestines.
Taking mineral oil by mouth can cause nausea, vomiting and stomach cramping. Because mineral oil is taken generally at night on an empty stomach, nausea is a common side effect of oil-based laxatives.
