CBD Oil is all the rage and there truly are so many ways to use it. One of my favorite relaxing, healing and mood stabilizing ways to use CBD oil are in a bath bomb, but at $12 and up per bomb. No, just no. That is why I had to create a simple DIY CBD Oil Bath Bomb Recipe…… 

Can CBD oil be used topically?

Yes, CBD  oil is very safe as well as effective when used topically. CBD is a great alternative for those looking to avoid the use of over the counter steroid creams and other pain relievers.

Used topically, CBD oil can be directly applied to certain areas of the body as an effective means of relieving pain and soreness, reducing inflammation, and soothing inflammatory skin conditions such as psoriasis, dermatitis, and eczema.

Most users find with regular use, localized pain is significantly reduced and effects last one to 48 hours.

You can read more in this post about the many uses and forms of CBD oil.

How CBD oil works for pain?

CBD oil’s effects can increase the natural levels of pain-relieving endocannabinoids, decrease inflammatory responses, and desensitize pain receptors (1). As simply put as possible,  endocannabinoids have a balancing and healing effect and CBD oil increases the natural cannabinoids available in our body, to help relieve pain.

Will CBD oil relax me?

CBD oil is great for improving anxiety, mood and is a known anti-depressant (2.) As a result of these properties, CBD oil is also shown to help with sleep. It’s also shown improvement with daytime sleepiness (3.) The improvements were seen in these areas without the use of prescription drugs, which is one reason why it has recently gained popularity.

Ok, so I know the rubber bands aren’t cute, but I like securing them so the bomb forms well!

I recommend using Medterra CBD oil.  The amount of oil you use in the recipe, depends on your desired dose. I recommend starting with 5-10 mg and working your way up very slowly and gradually.

CBD Oil Bath Bomb Recipe

Servings 6 average bombs


  • 1 cup baking soda
  • 1/2 cup citric acid
  • 1/2 cup epsom salts
  • 1/2 cup cornstarch
  • 2 T coconut oil melted
  • 1 tsp water no more!
  • CBD oil see notes

Option to add 5-10 drops essential oils of choice (peppermint and lavender are very soothing)


  1. Combine all dry ingredients in a medium bowl. Stir to remove any clumps.
  2. In a separate small bowl, combine all wet ingredients and mix very well so CBD oil is evenly distributed throughout your bath bombs.
  3. Slowly add wet ingredients to dry, stirring the entire time. If you see fizz or foam, you're adding too quickly.
  4. Once mixed, place in molds. I do this by squeezing a small amount in my hands and placing into each half of mold and press together.

  5. Wait one hour and gently remove from molds. The key here is to easily remove from molds without breaking, but not leaving in so long that they stick and are hard to get out.

  6. Allow to dry overnight or 8 hours.
  7. Store in airtight glass container until ready for use.

    1. Hi Joanna! I personally use 1 full dropper of the 1000mg CBD per bomb so each one contains roughly 33mg of CBD oil. I hope this helps!

      1. So how many dropper full’s comes in a bottle? Would it be one bottle for a recipe or I don’t know? I’ve read that you never know how many bath bombs you’re going to get out of the recipe so how do you go about determining droppers per batch?

        1. Hi Sandi, I am not sure how many droppers are in each bottle. This recipes yields 6 bombs. I personally use 1 full dropper of the 1000mg CBD per bomb so each one contains roughly 33mg of CBD oil. I hope this helps!

      2. Hi Melissa!
        So just reading your recipe and your comments, the recipe says it yields about 6 average bath bombs and your comments say you use a full dropper per bomb, so do you add 6 full droppers when you are mixing your recipe?

    1. Thank you so much for pointing that out Laura! I updated the post and the link now points to coconut oil.

  1. I’m using my own CBD oil, so how much would a full dropper be? 1/2 tsp? Full tsp? Per recipe would be better than per bomb because some people might be using smaller molds.

  2. I use the metal bath bomb molds. Should I spray them for an easier release. Mine tend to break in the center.

    1. I haven’t tried those, but I haven’t experienced sticking and am guessing you will be fine. Please let me know how they turn out!
