"Palpitation: "Pain in the heart" and palpitation of this organ are due to gases in the digestive organs. These symptoms are of rare development and are not dangerous, although they are usually the source of much needless apprehension on the part of the patient.

and the bad taste in the mouth.............
"Throughout most of the fast, the fasting individual is annoyed by a very bad taste in the mouth. This may be alleviated somewhat by a daily scrubbing of the tongue with a toothbrush. This should not be done, however, until after the tongue has been examined by. the doctor who is conducting the fast. Mouth washes, lemon juice, etc., are not to be recommended. Gargling the throat is certainly of no value. As the fast progresses and the tongue clears up, the taste becomes less and less offensive, until, when the fast should be broken, the taste in the mouth is very pleasant."
