I have used this foot soak before, but scalled back somewhat. I would use lavender or tea tree oils instead because anything in the peppermint family, I absorb to quickly and it tends to burn my feet
My feet were so sore and dusty tonight. This soak was just what they needed. I scaled it back to about 1/5 to make a small batch, since I was not giving as gifts. Also, I used tea tree oil and lavender. As much as the scent I made was nice, I really do think that the lemon and spearmint would be outstanding!
