14.3.67

udakāhibhastrām ucchvāsamṛttikayā striyāḥ puruṣasya vā pūrayet, nāsikābandhanaṃ mukhagrahaś ca //

When the slough of a water-snake (udakáhi) is filled with the breathed-out dirt (uchchhvásamrittika?) of a man or woman (and is held before the face and nose of any person), it causes those organs to swell.
