Rhus toxicodendron [Rhus-t]
This drug, in the 3d potency, is probably the best remedy for pure lumbago. Three times a day, for two days, is sufficient, for if not cured by that time Rhus is not the drug.
Berberis vulgaris [Berb]
Sometimes there is a lame back that simulates lumbago. For this, Berberis vul., in 5 drop doses, twice a day, for a few days, effects a cure.
