1. Law of similars/Like cures like (1796): Disease can be cured by a medicinal substance given in micro doses that produces similar symptoms in health people when given in large doses.
2. Law of minimum dose (1801): Infinitesimally small dose (only that amount of medicine is administered which is sufficient to cure the disease, not more that that, that means no overdosing) of potentised medicine to stimulate your innate healing powers. Potentising the medicine increases it collative medicinal powers through dynamisation (serial dilution and succussion/trituration) and avoids unwanted side-effects.
3. A single remedy (one remedy at a time) based on totality of the symptoms (1810): depending upon their constitution/totality of the symptoms which includes physical, mental, and emotional aspects/symptoms. This results in individualization i.e. it may require different medicine for different people suffering from same disease
4. Hering law of direction of cure (1845): Cure progresses from above downwards, from within outwards, from more important organ to less important one, in reverse order of coming of the symptoms
