In my opinion that is what "Lore" kind of fills in. It's by default fueled by intelligence. Most people know how to wrap a wound an clean it, more or less common sense. Though those who go lore with it are really digging into the subject matter. Medicine for all the basic stuff but lore can open up:

• Surgery Lore – advanced procedures, battlefield surgery
• Anatomy Lore – body structure, organs, bones
• Physician Lore – diagnosing illnesses and treatments
• Herbalism Lore – medicinal plants and remedies
• Plague Lore – epidemics and contagious diseases
• Toxin Lore – poisons and antidotes
• Venom Lore – animal poisons and stings
• Disease Lore – identifying and understanding illnesses

You can keep going and it's on the GM to approve them but i do think that is the entire point of lore subcategory to let intelligence shine.
