Aphorism number 38 discusses that a stronger dissimilar natural disease suspends a former disease. In aphorism 39 Hahnemann laments that allopaths have ignored this observation common in nature and continue to administer drugs that have a dissimilar of heterogenous action.
In aphorisms 34 and 35, Hahnemann argues that a medicine is able to cure a natural disease not merely by the virtue of its greater strength but primarily because of its similarity in affecting morbid alteration in the body.
In aphorisms 30 to 33, Hahnemann tells us that a person is affected by disease influences or falls sick only when he/she is weak or predisposed. But medicines have a much stronger and definite action and can affect humans more unconditionally.
In aphorism 28 Hahnemann argues that Homeopathy works and that is more important than how it works. In aphorism 29 he tells us that homeopathic remedies work by producing a similar artificial transient disease.
