To sweat wrap a leg you will need:
I like to mix the DMSO in the furazone but this isn't mandatory.
Apply the mix liberally from the knee to fetlock then cover it in the saran wrap
Apply pillow wrap and then bandage tightly.
I also alternate with a poultice.
Purchase a tub of ice tight
Apply the clay liberally the same way.
Cut a brown paper sack and wet it and wrap around over the poultice.
Pillow wrap and bandage the same way as before.
I like to sweat wrap one day, poultice the next and then a day off with a dry wrap.
