hello, I am looking for information about making a poultice for edema in joints & on tendons. the subject is actually a horse, and has the equivalent of edema in the front of the ankles due to an old surgery, (floating cartilage was remved from joint) as well as edema that collects in the tendon area similar to the achiles tendon due to an old splint that popped out of one of the longbones of the lower leg due to the concussive forces of hard footing. he's completely sound and working out daily. I just want to keep this in check. he normally carries a bit of edema in the front of the hind legs, even when not working. the edema in the front leg increases a bit with work, and concerns me more. zeolite? earth?
