Dear Sprinkle
here is a directory of homeopaths for each state,
www.homeopathic.org
have your father make an in person appt. for a proper consultation.
the "try this try that"- method of prescribing from on line discussion forums is not wise!
This is a complex situation-Homeopathy deals with each patient holisticly and as an individual,not from a diagnosed focus on one symptom like allopathic medicine does.
A full case history needs to be taken.
