Balloon flower root is rich in saponins, which irritate mucous membranes and commonly cause drooling, vomiting and diarrhea. It also almost always reaches a dog as a garlic-and-chili salad or a sugar syrup.

More about this food
Doraji, the peeled root of the balloon flower (Platycodon grandiflorum), is a Korean side dish and a traditional cough remedy. It is not on any veterinary list of vegetables to feed dogs, and there are three separate reasons to keep it away.
The first is the root itself. Doraji's sharp, bitter bite comes from platycodin saponins. Saponins are membrane irritants — the ASPCA lists saponins as the toxic principle in aloe and reports vomiting, lethargy and diarrhea in dogs. Expect the same category of irritation here: dogs that chew raw doraji often drool heavily and retch. The reason Korean cooks knead the root in salted water before using it is precisely to pull that compound out.
The second is what it comes packed in. A dog encounters doraji as doraji-muchim or namul: a salad tossed with gochujang or chili flakes, vinegar, minced garlic, salt and sesame oil, or the same root braised for a holiday table. Merck sets the clinical threshold for raw onion in dogs at 15-30 g/kg and states garlic is 3-5 times more toxic, and puts salt toxicosis signs at 2-3 g/kg with a lethal dose near 4 g/kg. The salt used to leach the bitterness stays in the dish too.
The third is doraji-cheong, the sugared syrup sold in Korean groceries and drugstores as a throat remedy, often blended with pear. It is a sugar or honey syrup, dense in calories, with nothing in it a dog needs. If the label says sugar-free, read the ingredients for xylitol before anything else: Merck reports hypoglycemia in dogs above roughly 100 mg/kg of xylitol and severe hepatic failure above 500 mg/kg, with hypoglycemia possible within 30 minutes.
Dried doraji deserves its own note. Unsoaked, it is a tough fibrous stick that does not break down, and in a small dog a swallowed piece can obstruct.
If your dog ate plain root, watch for drooling, vomiting, diarrhea and abdominal pain over the next few hours. If he ate the seasoned salad or any syrup, do not watch — call your veterinarian or the ASPCA Animal Poison Control Center at (888) 426-4435 now, and treat a possible xylitol product as a race against the clock. Do not induce vomiting at home. And do not dose a coughing dog with doraji syrup; a cough in a dog needs a diagnosis, not a folk remedy.
Frequently asked questions
He ate a bite of the seasoned doraji side dish.
The dressing matters more than the root: minced garlic, salt and sesame oil. A small bite usually passes as drooling and soft stool, but call your vet if vomiting repeats or he goes flat. Check gum color and urine color daily for five days, because Allium hemolysis is delayed.
My dog has a cough. Can I give him doraji syrup?
No. There is no evidence it helps a canine cough, it is a concentrated sugar syrup, and sugar-free versions may contain xylitol, which is dangerous to dogs in small amounts. A persistent cough needs a veterinary exam to find the cause.
She chewed raw doraji and is drooling a lot.
That is most likely saponin irritation of the mouth. Take the rest away, offer fresh water, and watch for vomiting or diarrhea over the next several hours. If either continues or she becomes lethargic, call your veterinarian.
