Also a popular remedy for sore throats, salt water can ease the discomfort caused by a cough the same way it helps a sore throat-through osmosis. When the concentration of salt is higher outside of the cells in your mucous membranes, water flows out of the cells to balance everything out. When water leaves the cells, swelling goes down, and discomfort is decreased. If you have a cough that happens to come along with inflamed tissue, this is a good route to take. It can also help dislodge any phlegm that’s hanging out and allow you to expel it easily.

Another well know spice in the kitchen cinnamon is also known for it's medicinal properties. While not really an herb I still think it's important to list it in our list of herbs and their uses. Cinnamon actually comes from the inner bark of a tree in the laurel family. It's been used for centuries and was a hot commodity for trade in ancient times. In fact during the first century A.D. in Rome cinnamon was 15 times more expensive than silver. The Chinese were probably the first to use cinnamon as a medicinal herb and used it to treat fevers, and diarrhea. In more modern times cinnamon has been found to stabilize blood sugar levels in diabetics, as it has an insulin kind of effect.
