For fever I use vinegar or essential oils. They both work faster than paracetamol or other OTC medications - 1-2 minutes as opposed to up to 10 minutes. To use the oils you just add 2-4 drops to a bowl of water, dip in a cloth, wring it out and swipe down the body. Or for the vinegar you mix it 1 part vinegar to 7 parts water and swipe down the body. It not only works faster and is cheaper but the essential oils help support the childs body in healing. I don't think the vinegar has any affect on healing but it works well on fevers. I haven't used Panadol since I discovered these remedies 12 years ago and they have never failed to work every time any of my kids are sick.
