The people of the Natrium Carbonicum type are listless, weak and emotionally unstable. They suffer from sensitivity to both cold and heat, and are quickly exhausted by physical and mental activity.

Their appetite is generally increased, but food causes indigestion and diarrhea; often, they complain of pronounced weakness of joints and ligaments, leading to frequent strains and dislocations.

Their mood is irritable and hypochondriac, shifting from absolute indifference to sudden anxiety and tears. Above all, music makes them cry, and a lightening-storm may cause depression. Eating, motion and fresh air relieve their complaints, while exertion and sunshine produce aggravation.

Natrium Carbonicum has been found effective in the treatment of many diseases, including those of the central nervous system, eyes, skin, the upper respiratory and the gastrointestinal tracts, and female reproductive organs.
