Family Camping Trip. What's in our first aid kit?

We decided these school holidays to go on our very first camping trip with all 3 of our little folk. We had been camping with our eldest 2, but this would be baby's first time in a tent!

With our car packed full to the brim, we set off on a 6 hour drive to beautiful Bremer Bay in Western Australia.
Honestly, packing for 5 people was quite overwhelming, but there was one thing that would be coming with us for sure; my 'home remedy' first aid kit.
We keep a conventional first aid kit in the car at all times, but it was important for me to bring along what we know and trust for our bodies.

This is what I packed in there:
Insect repellent - to keep those cheeky bugs from flying in our tent and biting our tasty bodies while we sleep.
Herbal Salve - for any bites, grazes, burns etc (came in very handy when Ewan got an ant bite...ouch!)
Chest Rub - To help ease the wheeze in the cold nights.
Arnic Balm - For aching joints after a long drive and for any bumps and bruises (or my toe which I almost broke when exploring the rocks as the beach!)
Garlic Infused Oil - To rub on feet at night if anyone was feeling ill. (Garlic is a natural antibiotic, antiviral and antifungal and absorbs gently through the soles of the feet.)
Colloidal silver - to clean any wounds and as a mouth wash gargle.
Tea tree - anti bacterial, anti fungal for wounds.
Cotton balls - for application of remedies.
Bandaids - Covering wounds, and when applied miraculously makes children feel better.

All of these home remedies came in very handy, and I was so grateful I had remembered them all.

We had a lovely time exploring the beaches and visiting the windmill. Unfortunately, baby Ewan did not enjoy camping as much as the rest of us, and was experiencing some bad teething pains. We made the most of it, but travelled home after 2 nights. Hopefully next time will be more successful and we get to do more exploring :)

What 'first aid' items do you pack with you when you go on holiday?
