Nurse
From Mushpedia
Helps the members of the laboratory team when they need to patch up the exploration squad, or heal the crew from constantly falling ceilings. Finola can already read medicine properties with her Medic skill, but it syncs so well with Nurse (use to perform expensive surgeries) that you may want to combine them.
When having to choose, however, Medic is far superior, as it gives you research bonuses as well as more effective healing, while Nurse by itself amounts to a mere 2 a day for a single heal (or 3 if you heal yourself).
Chun can gain the ability to read the properties of medicines from this. But, being who she is, there is no reason for others who can to not just share that knowledge with her.
