A 30c potency homeopathic dilution is 1 part of ignatia amara to 10 to the 60th power of the inert ingredient {correct if my math is wrong}. It is so extremely dilute that if you took the entire bottle [INADVISABLE} It would still be a single dose. Your main concern is if this is the remedy that matches a major amount of your symptoms. My advice is to seek a competent homeopath. Even when the hopefully right remedy is found, if it is taken too frequently, this in itself can cause problems. Fredric
