Spicy Foods
One home remedy for excess mucus is spicy foods such as jalapeno peppers or hot sauce. A study done on rabbits showed that capsaicin, found in chili peppers, caused an increase in the fluidity of mucus secretions.
Spicy foods help stimulate mucus membranes, helping clear your system by making you cough and sneeze. Many of us have used this method on rare occasions, like having hot tea and lemon or a glass of water with Tabasco sauce. If this sounds like something that could be useful in regular use, try adding more spice to your diet gradually. It might take your body a little time to get used to the extra flavorings, but if you make it part of your daily routine (coughing is optional), it may just become part of your normal diet.
Another study concluded that spicy foods increased cilia beat frequency in the airway epithelium. The cilia are tiny hairs inside our lungs that help clean out debris and mucus from the respiratory tract. Spicy foods increase airflow in the nasal passageways, thus helping to remove excess mucus. This helps with congestion and breathing problems due to excess mucus in the airways caused by allergies or a cold.
