Coconut oil and baking soda are two of the most versatile natural ingredients you can keep in your home. Alone, each offers its own set of benefits. Together, they can be combined in simple ways to address common concerns like nail fungus, skin irritation after hair removal, and dark patches on elbows, knees, and underarms.
Below are three easy-to-make remedies, each using these two pantry staples in slightly different ways.
1. Nail Fungus Treatment – Baking Soda & Apple Cider Vinegar
What you need:
- 1 tablespoon baking soda
- 2 tablespoons apple cider vinegar
How to make it:
Mix the baking soda and apple cider vinegar in a small bowl. The mixture will fizz. Stir until it forms a smooth paste.
How to use it:
Apply the paste directly to the affected nails. Leave it on for at least 15 minutes. Rinse with warm water and dry thoroughly. Repeat four times per week. This same mixture can also be applied to the scalp to help with dandruff.
2. Post-Shave Exfoliating Paste – Baking Soda & Water
What you need:
- 1 tablespoon baking soda
- 1 tablespoon water
How to make it:
Mix the baking soda and water until they form a thick, smooth paste.
How to use it:
Apply the paste to your legs or arms immediately after shaving or hair removal. Leave it on for 5 minutes. Rinse with warm water. This helps prevent irritation, reduces small bumps, and leaves skin feeling smooth.
3. Dark Spot Lightening Mask – Baking Soda, Coconut Oil & Lemon
What you need:
- 1 tablespoon baking soda
- 2 tablespoons coconut oil (warmed to liquid)
- Juice of 1 lemon
How to make it:
Mix all three ingredients in a small bowl until well combined. The mixture will be thick and slightly grainy.
How to use it:
Apply the mixture to areas such as the back of the neck, elbows, underarms, knees, or groin. Leave it on for 20 minutes. Rinse with warm water and pat dry. Use once or twice per week for gradual lightening of dark spots.
Why these work
- Baking soda gently exfoliates dead skin cells and helps balance pH.
- Coconut oil deeply moisturizes and has natural antimicrobial properties.
- Apple cider vinegar is antifungal and helps restore the skin’s acid mantle.
- Lemon juice provides natural bleaching properties to lighten dark patches.
Important safety notes
Do a patch test on your arm before using any of these mixtures on larger areas. Avoid using lemon juice on broken or irritated skin, and never apply it before sun exposure – lemon can make your skin more sensitive to UV rays. Each remedy is for external use only.
A simple, natural approach
