Preparation

• 1). Pour the boric acid, corn starch, and baking soda into your bowl. You may substitute arrowroot powder or baking powder for any of the above ingredients at your discretion, providing the total amount of dry ingredients measures 1 cup.
  
  
• 2). Whisk dry ingredients together thoroughly to ensure there are no clumps in the mixture. Hold your face away from the bowl as you mix to avoid breathing in any of the powder.
  
  
• 3). Place 3 drops of lavender essential oil, 8 drops of peppermint essential oil, and 3 drops of tea tree essential oil into the powder mixture using the eyedropper. Clean the eyedropper with isopropyl alcohol, inside and out, between essential oil selections to avoid contaminating each bottle of oil with another.
  
  
• 4). Mix the essential oils into the powder mixture thoroughly, using the wire whisk. Check for any larger clumps and continue to whisk until clumping is minimal.
  
  
• 5). Let mixture sit overnight in the bowl to dry thoroughly. Place the bowl in a cool, dry place free from dust and drafts.
  
  

Application

• 1). Check for any lumps in the mixture the following morning. If you find any lumps, either sift the mixture with a flour sifter or pour into a large, zippered plastic bag and work the lumps out with your fingers.
  
  
• 2). Pour the mixture into a clean container with a shaker top and store in a cool, dark place. Use a container with a sealable cap that covers the holes when not in use
  
  
• 3). Shake the foot powder onto clean dry feet, including in-between and underneath the crook of your toes, before putting on your socks and shoes.
