Your party is walking along a path when in front of you a man doubles up, clutching his abdomen. When you reach him to start an examination, he’s
retching, which soon turns to actual vomiting. As you put your hand on his forehead, you realize he’s running a fever. What’s going on?
One explanation for these symptoms is the man has a kidney stone. This could be the cause of the sudden pain in his abdomen, as well as the vomiting and fever.
Kidney stones are crystals that form when the body is unable to dilute certain substances sufficiently and they clump together instead of being excreted from the body. Kidney stones can cause a lot of pain. Some stones are too large to pass on their own and require medication or medical procedures (such as shock- wave therapy) to treat.
While making plans for evacuation, increase the fluids the patient is consuming. It’s possible that he’ll pass the stone, although it’s not an experience he’ll care to remember. Meanwhile, concentrate on getting him out of the wild as quickly as possible.
Many field edge plants like gravel root and queen of the meadow have been used for centuries to help break down kidney stones. You can take them as an infusion or simple tea, but they are more effective if the rootstock is used as a decoction.
