اِسْتَفْرَمَت

She (a woman) applied a medicament to her vulva, or vagina, to contract it: (S, K: *) or she stuffed her vulva, or vagina, (T, TA,) with the stones of raisins, and the like: (TA:) the women of [the tribe of] Thakeef, having a wideness in that part, made this use of the stones of raisins, desiring thereby to contract it: (M, TA: *) [see also 2: and see فَرْمٌ:] the epithet ↓ فَرْمَاءُ is applied to her who does thus; as also ↓ مُسْتَفْرِمَةٌ. (M, K.)

And [hence] one says of a mare, اِسْتَفْرَمَتْ بِالحَصَى, meaning (assumed tropical:) She caused the pebbles to enter her vulva by her vehement running. (TA. [And the same is implied in the S by an example and explanation of the particle n.])
