    Hi Peter,
    Do you have any insights on the energetic nature of cows bone? My online search found properties of sheep, ox & pig bone, generally entering the kidney & with a warm nature. I couldn’t find anything on specifically cows bone!

    Being bone, I presume it has an affinity for the kidneys.
    Regards, James
