3. Boswellia
This herb, more commonly known as frankincense, has been used for centuries to treat coughs, particularly those than come from inflammation of the lungs or other areas, Dr. Fenster says. Its potent anti-inflammatory compounds can help both in soothing a cough and fighting the oral pathogens that can cause them, he explains. Dissolving boswellia in hot water and inhaling the steam helped reduce coughing from asthma and bronchitis, according to a study published in the Journal of Traditional and Complementary Medicine.

4. Ginger
“Eating pungent spices, including ginger, cinnamon, and anise, can help strengthen your respiratory system,” Dr. Loo says. These spices can be brewed into a delicious herbal tea and the warm water and steam have the added benefit of helping to open up your lungs, she says. Purified ginger put in a nebulizer helped relax people’s airways and reduce coughing, particularly “dry” coughs related to asthma, according to a study published in the American Journal of Respiratory Cell and Molecular Biology.
