For rust prevention: When my dad used to do a lot of classic car resoration he used a lot of Vaseline on components to prevent rust, and also if parts were going to sit in a box for a while would cover them in a fine layer again, to stop them rusting in storage.
As for being toxic...I ate most of a tub when I was 7 (it was strawberry flavour) and it didn't do me any harm! The extra eye in the middle of my forhead is perfectly normal ;p
For me bushcraft is a bit like ultralight hiking and so I like things that have multiple uses. Vasoline can be used as lip balm, burn treatment, fire lighting, rust prevention, lubricating o-rings or bits of machinery and so it sounds like an ideal thing to have along!
Vaseline shouldn't be put on a burn immediately, as it can trap heat in (apparantly) but it is (apparantly) good for aftercare because it forms a seal over the burn, stopping bacteria getting in and thereby helping to stave off infection. Apparantly Never tried it m'self, I try not to get burned
Hmmm not convinced by that - I put cold running water on burns for at least 10 minutes!
After that watergel is pretty good on mild burns - my paramedic buddy suggested it and I had a chat with a doctor buddy and he agreed - clearly not for severe burns but the old "hot billy can" moments!
Aye well I should have stated apart from water BR but I thought that was stating the obvious...
On the last course I did, the instructors (paramedics) stated that nothing went on a burn except water to cool it and if you had to keep it clean, then clean plasticbject. Anything else including vaseline would be treated as a foreign object by the body and/or accelorate infection.
Again I have had different training. Clingfilm for example as a good burn covering.
This is the Waterjel stuff I have been advised to use - having tried some (on minor burns) I have found it very soothing. Clearly its not going to resolve full thickness burns or replace proper tratement. But as a sooth to a minor but painful burn I have to say I'm impressed
