Adding a few drops of tea tree to an unscented oil can help with diaper rash and fungal infections. Tea tree is a stronger oil that can be harsh on the skin, so it should be avoided on babies younger than 6 months old and carefully patch-tested on older infants.
Premature: Since premature babies have very thin and sensitive skin, it is best to avoid the use of essential oils. Rashes: Lavender, Roman chamomile, rose otto, or sandalwood. Dilute and apply. Tonsillitis: Ginger, lavender, lemon, or melaleuca (Tea Tree), Roman chamomile.
