Holy Basil, The herb is used to treat lung inflammation in India. For treating bronchitis, it's best to get an actual leaf of the plant if you can, and chew on it raw. You can also find holy basil teas online or at most natural food stores, although those may be less effective.
Malabar Nut, This can be used in combination with, or instead of, holy basil. Ayurvedic practitioners recommend chewing on the leaves, but in the U.S., you may be able to find only liquid extracts of the plant.
