Two inexpensive ingredients, one homemade mixture, and a promise to relieve everything from dry skin to stomach problems. It sounds almost too good to be true.
Olive oil and baking soda have been used separately in households for generations. Olive oil is valued for its healthy fats and moisturizing properties, while baking soda is known for its ability to neutralize acids.
But recently, the combination has gained attention as a supposed remedy for 12 different health problems.
Here’s the important truth: there is no reliable scientific evidence that mixing olive oil with baking soda cures these conditions. Some individual uses have a basis in science, but others can actually cause harm.
5
1. Dry Skin
Olive oil can act as an emollient, making skin feel softer by reducing moisture loss.
However, baking soda is alkaline and may disrupt the skin’s natural protective barrier.
For dry skin, a fragrance-free moisturizer or plain petroleum jelly is generally a better choice than this mixture.
2. Cracked Heels
Some people believe olive oil and baking soda can repair cracked heels overnight.
Although olive oil may temporarily soften the skin, baking soda can cause irritation, especially when cracks are deep.
A urea-based foot cream, gentle care, and protective socks are usually more appropriate.
3. Dark Spots on the Skin
Baking soda is sometimes promoted as a homemade exfoliant for age spots.
But scrubbing the skin with alkaline powders may trigger irritation and worsen pigmentation.
Olive oil doesn’t make baking soda an effective dark-spot treatment.
Daily sunscreen and appropriately formulated skincare products have stronger evidence.
4. Wrinkles and Fine Lines
Moisturizing can make fine lines caused by dryness temporarily less noticeable.
However, olive oil and baking soda cannot reverse established wrinkles or restore lost collagen.
Baking soda may actually leave facial skin irritated and dry.
5. Heartburn and Acid Reflux
Baking soda, or sodium bicarbonate, can neutralize stomach acid.
This is why sodium bicarbonate appears in some antacid products.
However, drinking a homemade olive oil and baking soda mixture is not a recommended treatment for reflux.
Excess baking soda can cause dangerous changes in the body’s acid-base balance and deliver a large amount of sodium.
People with kidney disease, heart failure, or high blood pressure may be especially vulnerable.
6. Joint Pain
Some viral remedies suggest rubbing olive oil mixed with baking soda onto painful knees.
Gentle massage may provide temporary comfort, but the mixture hasn’t been shown to treat arthritis, repair cartilage, or reduce joint inflammation.
Baking soda can also irritate sensitive skin.
7. Fungal Infections
Baking soda has demonstrated some antifungal activity under laboratory conditions.
However, this doesn’t establish homemade baking soda mixtures as effective treatments for athlete’s foot, nail fungus, or other fungal infections.
Using inappropriate home remedies may delay effective treatment.
8. Bad Breath
Baking soda is used in some professionally formulated oral-care products.
But mixing it with olive oil and rubbing it on teeth or gums hasn’t been proven to treat persistent bad breath.
Bad breath can result from dental problems, dry mouth, or other conditions.
Brushing with fluoride toothpaste, cleaning between the teeth, and seeing a dentist are more dependable approaches.
9. Teeth Whitening
Baking soda is included in certain toothpastes because of its mild abrasive and stain-removing properties.
However, homemade baking soda and olive oil mixtures are not equivalent to tested toothpaste formulations.
They don’t provide fluoride protection and may encourage excessive scrubbing.
Use an appropriately formulated toothpaste instead.
10. Constipation
Olive oil is sometimes promoted as a natural laxative.
Although dietary fat can influence digestion, there is insufficient evidence that taking spoonfuls of olive oil reliably treats constipation.
Adding baking soda doesn’t make the mixture more effective and may introduce unnecessary risks.
Fiber, adequate fluids, physical activity, and evidence-based constipation treatments are better-supported options.
11. High Cholesterol
Extra-virgin olive oil can be beneficial for cardiovascular health when it replaces foods high in saturated fat.
Its monounsaturated fats are one reason it’s commonly recommended as part of a Mediterranean-style diet.
But adding baking soda doesn’t improve its cholesterol-related benefits.
The advantage comes from overall dietary choices, not a special homemade formula.
12. Body Detoxification
One of the most dramatic claims is that olive oil and baking soda can flush toxins from the liver, kidneys, or intestines.
There is no convincing evidence for this.
The liver and kidneys already perform essential functions involved in processing and removing waste products.
Drinking baking soda mixtures can be dangerous, particularly in large or repeated doses.
What the evidence really says
| Popular claim | Reality |
|---|---|
| Cures arthritis | Not proven |
| Removes wrinkles | Not proven |
| Eliminates fungal infections | Not established |
| Treats acid reflux | Baking soda can neutralize acid, but homemade mixtures carry risks |
| Lowers cholesterol | Olive oil may help when replacing saturated fat |
| Detoxifies the body | No scientific evidence |
A Better Way to Use Olive Oil and Baking Soda
Instead of combining them as a medicinal treatment, use each ingredient for an appropriate purpose.
Olive oil is excellent in salads, cooked vegetables, and other meals.
Baking soda is useful in baking and household cleaning when used correctly.
For a simple heart-healthy dressing, try this:
Easy Mediterranean Olive Oil Dressing
Preparation: 3 minutes | Serves 2
Ingredients
- 2 tablespoons extra-virgin olive oil
- 1 tablespoon lemon juice
- ½ teaspoon dried oregano
- A small pinch of black pepper
Instructions
- Combine the olive oil and lemon juice.
- Add oregano and black pepper.
- Whisk until combined.
- Drizzle over vegetables or a fresh salad.
No baking soda is needed.
Who Should Avoid Homemade Baking Soda Remedies?
Swallowing baking soda as a home remedy can be particularly risky for people with kidney disease, heart conditions, high blood pressure, or sodium-restricted diets.
It can also interact with medications by changing stomach acidity.
Excessive intake may cause vomiting, electrolyte disturbances, or metabolic alkalosis, a potentially serious condition.
On the skin, repeated baking soda applications may cause irritation, dryness, or damage to the skin barrier.
If you’ve consumed a large amount of baking soda or develop severe symptoms, seek urgent medical advice.
The Bottom Line
Olive oil and baking soda are both useful household ingredients, but their benefits are often exaggerated online.
Olive oil can support a healthy diet and has some moisturizing properties. Baking soda has legitimate uses in cooking, cleaning, and carefully formulated products.
But mixing them together doesn’t create a treatment for 12 diseases—and swallowing or applying the mixture can sometimes do more harm than good.
The real secret isn’t combining two ingredients. It’s knowing when each one is useful, when it isn’t, and when a health problem needs proper medical care.
