Has he been tested for lymes? I know that a combo of tea tree oil, mint tea and witch hazel helps rashes.I make mine using a spray bottle filled with a cup of mint tea, half a bottle of witch hazel and about 10- 15 drops of tea tree oil. Shake well before using. So does a sock filled with plain old oatmeal in the bath. Works on sunburn too. Good luck.
You mean Lyme's disease, carried by ticks? I'm interested in trying your spray, thank you!
