I pulled this bit from the article on CNN. Hopefully it answers your question.
Cough and sore throat
The use of vinegar medicinally starts with the father of modern medicine, Hippocrates. He would mix it with honey and use it for chronic coughs and sore throats, and the suggestion continues today across the internet.
Many parents might think this is a natural and safe option for their children. The American Academy of Pediatrics doesn't have an official stance on the use of apple cider or other vinegars as a health aid, but spokeswoman Dr. Jennifer Shu urges caution.
"I would just think that the vinegar would irritate the throat even more," says Shu, an Atlanta pediatrician and author of "Food Fights". "But diluting it and mixing it with other ingredients such as salt or honey might decrease any pain that the vinegar might cause."
The University of Arizona's Johnston cautions against trying any vinegar straight, due to the risk of inhaling the liquid and damaging the lungs.
"Vinegar has that strong smell and puckering taste, so if you take a breath, you could inhale it into your lungs as you swallow," she says. "It can burn the lungs a little, because it is an acid."
"It can also burn your esophagus," says Dr. Andrew Freeman, director of cardiovascular prevention at National Jewish Health in Denver, Colorado. "And if you're predisposed to reflux, ulcers or stomach problems, it could certainly make those worse."
