Proved by Hahnemann, Hering and others.
Persons who are in the habit of taking carbonate of soda for sour stomach get a proving of this remedy. I have met some of these people and been able to confirm many Natrum symptoms.
Old dyspeptics who are always belching and have sour stomach and rheumatism; after twenty years they are stoop-shouldered, pale, sensitive to cold, chilly, aggravated by the least draft; require much clothing; unable to resist the cold or the heat; require a medium climate; are worse from the changes of the weather; their digestive, rheumatic, and gouty troubles are all worse from the weather changes.
Mind: A state of trepidation from the slightest noise, the slam of a door; nervous excitement and palpitation with great prostration; nervous weakness with trepidation; weakness from slight exertion of mind or body; internal and external trembling.
The rattling of paper causes palpitation, irritability and melancholy. Estrangement from family and friends. Aversion to mankind and to society; to relatives, to strangers; feels a great division between himself and them; sensitive to, certain persons.
Music causes a tendency to suicide, melancholy, weeping and trepidation; playing the piano is so exhausting that she must lie down; music causes great sadness which increases to religious insanity.
This is true of all the Sodiums, but especially so of Natrum carb.; aggravation from the slam of a door, a pistol shot, which causes headache and complaints in general, aggravated from music.
Digestion: The more soda these patients take, the more flatulent do they become; they are stoop-shouldered; digestion is difficult, and finally milk will not digest at all, bringing on a diarrhoea with undigested, lienteric stools; also, starch causes flatulence and looseness of the bowels, Many symptoms from drinking cold water when overheated.
Urine offensive like that of a horse, from a vegetable or milk diet. This is not so marked as in Nitric ac., but resembles it.
Skin: Natrum carb. throws out eruptions upon the knuckles and fingertips; also the toes; vesicular eruptions open up and form ulcers on the joints of finger-tips.
Borax, Sepia, Ars., and Natrum carb. are the remedies most inclined to produce ulceration of the tips and knuckles of the fingers, and also the toes.
Vesicular eruptions on the body in patches and circles; the herpes family is especially, related to Natr. carb.; zona, herpes labialis, herpes preputialis; patches as large as a dollar on the hips, thighs and back. Smaller patches show vesicles containing a white serum, burning, smarting and itching, better from scratching.
The eruption passes away with a crust, but will often ulcerate, it does not heal and an ulcer forms. Circulation feeble; wounds suppurate. Feet and skin burn. Crusty eruptions on the skin that have not been vesicular; but most Natr. carb. and Natr. mur. eruptions are of the vesicular form. Tingling, biting, itching, changing place, now here and now there; cold skin; sweaty body.
Mind: Nervous exhaustion, physical exhaustion, weakness of mind and body.

Old cases of brain fag with weakness and trepidation. The body troubles are aggravated from cold and in the winter; as cold as if he had no blood in the body, extremities cold, and he cannot get them warm; cold as ice to, the knees and elbows.
