DIY Mermaid Bath Salts

When your back’s tight, your shoulders are screaming, and even stretching feels like too much effort—sometimes, you just need a little help in a jar.

Enter this soothing DIY Sore Muscle Relief Balm. It’s warming, nourishing, and infused with essential oils known for easing tension and boosting circulation.

I keep a tin of this on my bedside table and another in the kitchen drawer. It’s a go-to remedy in our house for everything from growing pains to post-walk stiffness—and trust me, with a big dog like Aloo dragging me around, I know sore calves!

Why Make Your Own Muscle Balm?

Commercial rubs often contain synthetic fragrances, petroleum byproducts, or ingredients that can be too harsh on sensitive skin. When you make your own, you’re in full control—and it doesn’t have to be complicated or time-consuming.

This DIY balm is:

• Petroleum-free and non-toxic 
• Packed with anti-inflammatory oils 
• Warming without the burn 
• Gentle on sensitive or mature skin 
• Perfect for gifting 

Ingredients You’ll Need

Base Oils & Butters:

• ¼ cup shea butter – rich in vitamins and helps deeply hydrate skin 
• 2 tbsp beeswax pellets – thickens the balm and adds a protective barrier 
• ¼ cup coconut oil – light carrier oil with natural anti-inflammatory properties 
• 2 tbsp magnesium oil (optional but recommended for extra relief) 

Essential Oils Blend:

• 10 drops peppermint essential oil – cooling and refreshing 
• 8 drops eucalyptus essential oil – helps reduce inflammation 
• 6 drops rosemary essential oil – boosts circulation 
• 5 drops lavender essential oil – calming and soothing 
• 4 drops ginger essential oil – gentle warming effect (skip if sensitive to heat) 

Note: Always do a patch test before slathering it on.

How to Make It – Step-by-Step

1. Melt Your Base
   In a double boiler (or a heat-safe bowl over simmering water), melt together the shea butter, beeswax, and coconut oil until fully liquified. 
2. Add Magnesium Oil (Optional)
   Remove from heat and stir in magnesium oil if using. This may cause some bubbling—that’s normal! 
3. Cool Slightly
   Let the mixture cool for a couple of minutes. You want it warm but not hot to avoid damaging the essential oils. 
4. Stir in Essential Oils
   Add your essential oils and mix thoroughly with a wooden stick or glass stirrer. 
5. Pour into Tins or Jars
   Carefully pour the balm intometal balm tins or glass jars. Let cool uncovered until set. 
6. Label & Store
   Store in a cool place away from direct sunlight. It should last 6–12 months. 

How to Use Your Homemade Muscle Rub

• Massage a small amount into sore muscles after a shower or bath. 
• Use it before bed to help loosen tight areas and promote deeper sleep. 
• Rub into feet and calves after long days of standing or walking. 
• Warm it between your hands for easier spreading on cold days. 

Bonus tip: Rub a bit onto temples and neck during tension headaches—peppermint works wonders.
