Regurgitation

(medicine) Reverse circulation of blood in the heart due to defective functioning of the valves.
(physiology) Bringing back into the mouth undigested food from the stomach.

Regurgitation refers most commonly to stomach contents moving back up into the oesophagus or all the way to the mouth — but short of the full reflex drama of vomiting. Also applied to backflow of blood through a leaking heart valve.

— Stuart Judge

See heart; indigestion.

A backward flowing (for example, casting up of undigested food, backward flowing of blood into the heart or between the chambers of the heart).

An explanatory theory of materialization phenomena that suggests that the white substance issuing from a medium's body, which is taken for ectoplasm, is something that the medium swallowed before the sitting and brought up at the appropriate moment. The theory was put forward by the Society for Psychical Research, London, in the case of Eva C., accused of fraud in 1922. Wide public attention was also aroused by the case of the British medium Helen Duncan, in which the theory was considered a satisfactory explanation.
