There are many things you can drink to relieve heartburn, but some work better than others. Milk is a good option because it soothes the stomach by neutralizing acid. You can also try herbal tea, which can have a calming effect on the digestive system. If you're looking for something with a little more kick, vinegar or lemon juice can also help to reduce heartburn by increasing the production of saliva, which helps to neutralize stomach acid. Whatever you choose to drink, make sure you sip slowly and avoid gulping, which can worsen heartburn symptoms.
