Well aware of the erudition of his half-brother , & Aqay-i-Kalim , in matters pertaining to medicine , he , under various pretexts , sought enlightenment from him regarding the effects of certain herbs and poisons , and then began , contrary to his wont , to invite & Baha'u'llah to his home , where , one day , having smeared His tea-cup with a substance he had concocted , he succeeded in poisoning Him sufficiently to produce a serious illness which lasted no less than a month , and which was accompanied by severe pains and high fever , the aftermath of which left & Baha'u'llah with a shaking hand till the end of His life . Natural preparations have been used for thousands of ages for a variety of purposes including as medicines , poisons , and psychotropic drugs . The underlying premise of homeopathic medicine is that symptoms are not simply something " wrong " with the person , but that symptoms represent adaptive and defensive efforts of the body to deal with infectious disease , environmental poisons , and / or stress .
