Much rattling of mucus in the chest.
Kali sulph. is useful in those cases in which, after the case is well along, there remains a persistent rattling of mucus, which reminds one of Pulsatilla, but it does not finish up the case. Pertussis (Whooping Cough).
Kali sulph. where the expectoration is like that of Pulsatilla, and the aggravations and ameliorations are similar.
It seems to be what we call the “chronic” of Pulsatilla. Pneumonia.
Kali sulphuricum is so like Pulsatilla that it deserves the name of its “chronic,” and if Pulsatilla does not cure such a case, and it tends to get worse instead of better, Kali sul. will complement it very nicely. This is so, not only in catarrh of the nose, but also where the process continues downward to bronchi and lungs. It is especially useful where there is much rattling of mucus remaining.
If Pulsatilla does not do all, Kali sulph. is its chronic and often follows well on the same indications.
