Kali mur is a tissue salt that may provide relief for symptoms where there is thick, white nasal discharges and catarrh, earache, stuffy head colds, sore throats and mouth ulcers. This salt, according to Schuessler, is present in brain cells, blood corpuscles, muscles, nerves and inter-cellular fluids. It is found in the blood in greater quantity than any other inorganic salt, with Nat mur being the next closest. Symptoms that produce congestion such as glandular swellings, nasal discharge or catarrh with whitish discharge may suggest use of Kali mur.
