v2.c35.3

2 The ulba, mentioned in 1.1, is not the placenta (aparā), as Aruṇadatta says, unless he gives another meaning to that term. The Kairalī commentary quotes a sensible interpretation by the Śārakṛt (another commentator): that by which the newborn child is besmeared (upalipta), is called ulba or jarāyu; this description may refer to the vernix caseosa. Usually, ulba and jarāyu are not synonymous and do not designate the vernix. Jarāyu is in most cases the placenta, ulba the amnion. See on ulba: A. Wezler (1997).
