Milk is known as a particularly soothing and anti-inflammatory substance, particularly for the gut, but it is also effective for the throat. Animal fats tend to block irritants and pain receptors, helping tissues relax. If you suffer from asthma, drinking milk can protect the throat against irritants, making the threat of an asthma attack much lower. However, milk and dairy products can also stimulate the production of excess mucus, particularly if you are ill. If you are sick, you may want to avoid the use of milk to prevent asthmatic attacks, as it could exacerbate the issue of mucus blockage.
