UNDERWOODS HORSE MEDICINE is truly a remarkable product.  It heals wounds from
the inside preventing proud flesh and minimal scaring. It is easy to use. Most horses don't
mind being doctored with UNDERWOODS. Simply place a sprayer in the bottle, shake it well
and saturate the wound with the UNDERWOODS solution. Now take BAKING POWDER avaiable at any
grocery store and throw it on  the wound completely covering the entire area. Repeat this
twice daily for the first week. After the first week doctor the wound once a day until it heals.
Don't worry about the appearance on the wound as it heals. It will become very crusty looking.
Leave it alone and contuinue doctoring the area. Don't clean off the build up. When the wound
has healed from the inside out the crust will come off on its own. You will be left with the
best possible outcome for the wound.
