No they don't...
To get rid of hives, it's important to know what triggers them. As an example, hives from at increased heat to the body is a possible dry skin condition. A teaspoon full of cod liver oil in the morning can help deliver moisturizing properties to the skin 30 minutes before breakfast and prevent heat hives. Chronic hives may be from a constant allergic reaction to an environmental factor. Identify the factor, then either remove it from the environment or find a solution to the factor to combat the chronic hives situation.
