Well, here's something that no one mentioned. Years ago, I was cutting some teak with handtools. It might have been a chisel or a saw. I abraded my finger with the tool, and the cut was contaminated by the teak oil. Now, years later, I remember that the wound, a minor wound by DIY standards, took more than a week to heal. Anyway, I would caution you to be careful with the teak oil. Maybe wear latex gloves if you have cuts on your hand.
