|Bryonia acts on acute, exudative-stage inflammation, preferably within the serous membranes, but also in mucosae and synovial membranes. The effusions in the mucosae, serosa and synovial membranes are accompanied by inflammatory swelling and an intense pain. Congestion in the stomach region. The effects of Bryonia also encompass the digestive tract with affection of the stomach and spasms with acute colic pain due to the irritation of the intestinal mucosa. Peristalsis within both small and large intestines is reflex-activated under simultaneous exudation into the lumen of the bowels. Copious, watery, and possibly sanguineous diarrhea may occur. Gastric discomfort and pain in the abdomen worsen on movement and when touched. Pharyngolaryngi- tis, non-productive bronchitis with hacking cough (influenzas cough), pleuritis. Dry mucosae coupled with intense thirst for large quantities of cold water. Diminished bladder tonus and frequent release of light-colored urine. Aggravation on movement and on warmth. Amelioration at rest and when lying on the affected side.
