When the lump is grasped, he should then remove the jar;
then, placing a cloth between, one who knows measurements should break open the lump.
He should compress it with whatever is available—vimārga, ajapada, or mirrors;
he should knead the lump alone, but should not touch the intestines or the heart.
And having smeared it with sesame, castor, linseed, and mustard seeds,
the physician should foment the phlegm lump with pleasantly warm iron vessels.
