Astanga Hrudaya
तत्र पूर्वोदिता व्यापत्सिद्धिश्च न तथापि चेत् । आशये तिष्ठति ततस्तृतीयं नावचारयेत् ॥ ४ ॥
In that event, the complications (vyāpat) and their management (siddhi) are exactly as described previously (for emetics running downward). If, even after repeating the process properly, the medicine does not remain in the stomach/alimentary tract (āśaya), then a third dose should not be administered;
english translation
