Q. The Gemarah in Bechoros 6b says that I would have thought milk is Aver Min Hachai if not for the posik.
What is the status of lanolin oil, the oil is of sheep’s wool; may I use it on my lips, dishes etc?

A. Shach (Y.D. 81: 12) , P’ri Toar (ibid. 9) and other Poskim maintain that the prohibition of Ever Min Hachai and Yotze applies only to the meat itself. The lubricant Lanolin is extracted from the wool grease yielded from the wash when cleaning and preparing the wool. Adding the fact that the original secretion extract is unsuitable for human or even animal consumption (See Achiezer 2: 11,) therefore many Poskim permit its use. However, there are to be found in the market Kosher Lanolin and a further derivative from it; vitamin D3.

Horav Shlomo Miller’s Shlit”a opinion is that there are enough lenient factors involved to permit the use of Lanolin.
