Physiological Effects. —Lard, like other animal fats, is nutn ^but very difficult of digestion. Its topical effects are deiuulcenemollient. Both the flesh and fat of the hog have been long s' 1 !’? )V eto dispose to cutaneous disease; but it is no easy matter either to por disprove this opinion. - g for
Uses. —In medicine lard is principally employed as a t>a c ,unguents. It has been used, by friction, as an emollient; but tn fy n ,.tice is now obsolete. In pauper establishments it is sometim^^ t heployed, as a substitute for spermaceti ointment, to dress blisters, jjjcl*salt which lard sometimes contains, as well as the facility a sioOthis fat becomes rancid, are objections to its use.
