Vegeta takes a moment to consider what he can compare it to. Most the healing he's used to receiving is one extreme or the other; from sensu beans with their instant healing, to typical first aid that gave his body a chance to heal. He's somewhere in the middle. "I should be able to stabilize someone so they can survive until another healer could get to them, or handle simple injuries that could be treated quickly."

However, "I haven't had much of a chance to train it other than what I have done on myself to heal my tail back to full use." Maybe if he got some hands on practice it would help more, just like any other training. Though it was a bit rude to go and hurt someone just to heal them... even Vegeta isn't that bad. And on missions he tends to be on the front line for Red Team, and for the most they were pretty good at getting out of dangerous situations without needing much healing afterwards.
