I made up and administered 'pulsatilla' for Max as we discussed in the 15 minute consult. My question is: do I continue to administer the pulsatilla or is it a one off dose? His tummy upset is intermittent and unpredictable at this stage so should I just be administering the pulsatilla when he has the tummy upset or also as a preventative? And should he be having a tummy upset, what is the recommendation for frequency of dosing?
