Definitively so!
Clarke (in his Prescriber) also give the following:
Asaf 3C: milk late in appearing, or diminishing afterwards,
Urtica MT 5 drops in hot water (every 4 hours),
Calc phos 6C when the milk is poor in quantity, in pale lymphatic subjects, or people with history of poor milk production,
Silica 6C, in thin rickety subjects,
Phos 3C in tuberculous subjects,

Personally I have had great results with the urtica and with the Ricinis com 5C. Apparently Brewers yeast help as well.
