Potencies can't be indicated in any referance as those can be dependant on individual case.

Biochemic system is bit different as its remedies are somewhat isopathical type or homogenous..resembling the same tissue salts. Suppressions, proving effects, aggravations etc. can still be common. Homeopathic system of selecting single remedy is the work of great knowlewdge, skill and experiance and it may present both positive and wrong outcome if mistaken being too many remedies and theories also most remedies are bit hetrogenous type. So going towards biochemic can be bit easier, and better understood, but I am not yet sure, if it can cover complete healing due to just 12 remedies.
