Signs of hridayopasarana after enema

If a very sharp enema is pressed in forcefully in a patient with aggravated vata, the provoked doshas go to the heart and attack it (hridayopasarana), bringing at once fainting, insanity, burning, heaviness, salivation and various pains. A footnote cites another text that ascribes it to a sharp niruha and to an oil enema given with vata.
