I like to drink tea. You can find tea marketed for throat or respiratory health. You should see ingredients like licorice root, eucalyptus, ginger, fennel, nettle, and mullein

I like to collect and dry a bunch of mullein leaves and dry them every year. Tea with just mullein is tasty and soothing. You can also smoke it, I like to add it to joints on occasion. Smoking mullein will help me clear a bunch of congestion and gick
