Prep Time 15 minutes
Total Time 15 minutes
Serving Size 4 (3 cups bath salts)

Equipment

  • spice grinder OR pestle and mortar
  • airtight container or jar with lid

Ingredients

  • 2 tbsp finely crushed chamomile
  • 2 tbsp finely crushed lavender
  • 2 Tbsp dried calendula petals
  • 2 tsp finely ground oats
  • 1 Tbsp finely ground dried orange peel
  • 1¾ cups rock salt
  • ¾ cup baking soda
  • Optional: 8–10 drops lavender essential oil (pre-diluted in 1 tsp carrier oil)

Instructions

  • Prepare botanicals: Ensure all herbs, citrus peel, and oat flour are completely dry. Grind or crush them finely for smooth dispersal in the bath.
  • Mix dry ingredients: In a large bowl, combine rock salt, baking soda, chamomile, lavender, oat flour, orange peel, and calendula petals (if using). Stir well to distribute evenly.
  • Add essential oil: If using, dilute essential oil in 1 tsp carrier oil, then stir into the salt mixture until evenly blended.
  • Store: Transfer to an airtight jar or container. Keep in a cool, dry place away from humidity.
  • Use: Add ½–¾ cup to a warm bath. Stir water to help salts dissolve, soak 15–20 minutes, and relax. Optional: rinse and moisturize afterward.

Notes

  • Measure the herbs after crushing or grinding them. Volume changes when herbs are crushed. Whole flowers are fluffy and take up more space; once ground, they pack down and become easier to measure out accurately.
