Aphorism 292
§ 292
Aphorism 292 : Even the external surface of the body, covered as it is with skin and epidermis, is not insusceptible of the powers of medicines, especially those in a liquid form, but the most sensitive parts are also the most susceptible.1
1 Rubbing-in appears to favour the action of the medicines only in this way, that the friction makes the skin more sensitive, and the living fibres thereby more capable of feeling, as it were, the medicinal power and of communicating to the whole organism this health-affecting sensation. The previous employment of friction to the inside of the thigh makes the mere laying on the mercurial ointment afterwards quite as powerfully medicinal as if the ointment itself had been rubbed upon that part, a process which is termed rubbing-in, but it is very doubtful whether the mental itself can penetrate in substance into the interior of the body, or be taken up by the absorbent vessels by means of this so-called rubbing-in. Homoeopathy, however, hardly ever requires for its cures the rubbing-in of any medication, nor does it need any mercurial ointment.
