David said: They share some qualities but not as much as you mention. Mineral salt herbs affect the lymphatics, are much more mineral rich, do not contain much if any sodium, so do not increase BP or contribute to auto-immune disease. There are few true salt herbs beyond a few very salty seaweeds and glasswort, there are many mineral salt herbs. Only the herbs with iodine soften goiters, while the mineral salt herbs reduce lymphatic swelling.
