Testimony time: my son has had a horrible teething rash for months...I tried everything, including special steroid cream from his doctor, and nothing was working. Then I got my Lemongrass Spa Healing Balm.
Homemade Non-medicated Diaper Rash Cream: c organic unrefined coconut oil, c corn starch. Whip with beaters until fluffy. To make it medicated, add a few drops of Tea Tree Oil (use carefully, babies are sensitive).
