What does putting Vicks on the bottom of feet do?

An estimated 94% of American households have purchased Vicks VapoRub at some point, leading to countless folk remedies and anecdotal uses beyond its intended purpose. This widespread use has fueled a popular trend, but what does putting Vicks on the bottom of feet do?

Quick Summary

The practice of applying Vicks VapoRub to the feet is a folk remedy, primarily associated with soothing coughs, though scientific evidence for this use is lacking. However, the product's ingredients, like camphor and petroleum jelly, offer documented benefits for moisturizing skin, relieving minor aches, and potentially treating toenail fungus when applied topically.

Key Points

• Cough Relief (Unproven): There is no scientific evidence that applying Vicks to the feet will stop a cough, especially for respiratory symptoms where inhalation is key.

• Moisturizes Skin: The petroleum jelly base can be effective for softening dry or cracked heels when applied nightly with socks.

• Treats Toenail Fungus: The antifungal properties of ingredients like camphor and eucalyptus oil have shown some effectiveness against onychomycosis in studies.

• Soothes Minor Aches: The topical analgesics camphor and menthol can provide temporary relief from minor muscle aches and neuropathic foot pain by creating a cooling sensation.

• Safety Precautions: Avoid applying Vicks to broken skin or using it on children under two, as it can be toxic if absorbed in large amounts.

• Placebo Effect: Any perceived relief from cough symptoms may be attributed to the soothing ritual and powerful scent rather than a direct physiological effect.

Exploring the Folklore of Vicks on Feet

For generations, Vicks VapoRub has been a medicine cabinet staple, known for its strong, aromatic vapors that help relieve chest congestion. However, a persistent folk remedy suggests that rubbing it on the soles of the feet can also alleviate coughs, particularly at night. This practice is a great example of how home remedies are passed down through families, fueled by anecdotal evidence rather than scientific rigor. Many proponents claim it works like magic, while medical professionals generally attribute any perceived relief to the placebo effect or other factors.

The Science Behind the VapoRub Sensation

To understand why applying Vicks to the chest works but the feet may not, one must understand how the product functions. Vicks VapoRub contains active ingredients like camphor, menthol, and eucalyptus oil. When applied to the chest, the vapors from these ingredients travel through the air and are inhaled, creating a cooling sensation that tricks the brain into perceiving clearer nasal passages. The menthol and camphor also act as topical analgesics, or pain relievers, when applied to the skin, which can help soothe minor muscle aches.

The feet are simply too far from the nasal passages for the vapors to be effectively inhaled, and covering them with socks further obstructs any potential vapor inhalation. While some alternative theories suggest that stimulating nerves in the feet (reflexology) could calm the cough reflex, this idea lacks robust scientific backing.

Potential, Evidence-Based Benefits for Your Feet

While the cough remedy is largely unsubstantiated, Vicks can still offer some specific, evidence-backed benefits when applied to the feet due to its active ingredients. The following are supported by research and the known properties of its components:

• Toenail Fungus Treatment: Studies have shown that the camphor and eucalyptus oil in Vicks possess antifungal properties that can be effective against onychomycosis, or toenail fungus. In one small study, Vicks improved symptoms for a significant percentage of participants after six months of daily application. The petroleum jelly base also helps to lock in the antifungal ingredients.
• Relief from Neuropathic Pain: Camphor and menthol are known topical analgesics that can help desensitize pain receptors in the skin. For those with neuropathic pain in their feet, this can provide a cooling and numbing sensation that offers temporary relief from the burning or tingling associated with the condition.
• Softening Dry, Cracked Heels: The primary base of Vicks is petroleum jelly, a potent occlusive agent that locks moisture into the skin. For individuals with dry, cracked heels, applying Vicks and covering the feet with socks overnight can help soften and moisturize the skin. This effect is not unique to Vicks, and similar results can be achieved with plain petroleum jelly, but the addition of the camphor and menthol offers a pleasant, tingling sensation.

Comparison: Chest vs. Foot Application

To clarify the difference between the manufacturer's intended use and the folk remedy, here is a comparison of applying Vicks to the chest versus the feet.

Feature	Chest Application (Intended Use)	Foot Application (Folk Remedy)
Primary Mechanism	Inhalation of camphor and menthol vapors acts as a cough suppressant and creates a sensation of clearer breathing.	Topical application; relies on nerve stimulation or absorption through the skin.
Scientific Evidence	Backed by manufacturer studies and medical consensus for temporary symptomatic relief of cough and congestion.	Lacks substantial scientific evidence for treating respiratory symptoms.
Common Beliefs	Widely accepted and medically approved for chest and throat rub for cold symptoms.	Popular folk remedy for calming nighttime coughs, often with strong anecdotal support.
Documented Foot Benefits	Not applicable; focus is on respiratory relief.	Helps with toenail fungus, moisturizes skin, and may relieve minor aches and nerve pain.
Effectiveness for Cough	Effective for temporary relief by stimulating nasal passages.	Ineffective for respiratory symptoms due to distance from airways.

How to Use Vicks Safely on Your Feet

If you choose to use Vicks on your feet for issues like dryness or fungus, it's important to follow safe practices to avoid irritation or other adverse effects. Always perform a patch test on a small area of skin to check for any allergic reaction. Use a clean cloth or cotton swab for application, and never apply Vicks to broken or damaged skin, as this can increase the risk of camphor toxicity. Always wash your hands thoroughly after applying to avoid getting the product in your eyes. For addressing dry or cracked heels, applying a layer before bed and covering with socks is an effective method. For toenail fungus, apply a small amount to the affected nail once or twice a day. As with any medical concern, if symptoms persist, consult a healthcare professional for an accurate diagnosis and treatment plan.

Conclusion: A Remedy of Context

Ultimately, what putting Vicks on the bottom of feet does depends on your expectations. For those seeking a magical cure for a cough, the results are likely to be disappointing, with the placebo effect playing a significant role in any perceived relief. The manufacturer’s instructions, and the weight of scientific evidence, confirm that for respiratory relief, the chest is the intended area of application. However, the remedy is not without its merits. Thanks to its key ingredients, Vicks can be a useful, low-cost aid for minor foot issues like dry skin, aches, and fungal infections, even if it doesn't quiet a cough. The widespread belief in its efficacy for colds highlights the enduring power of anecdotal tradition in home healthcare, but separating the myths from the verifiable benefits is key to using this product effectively.

Frequently Asked Questions

Does putting Vicks on your feet really stop a cough?

No, there is no scientific evidence to support this claim. For Vicks to relieve a cough, the menthol and camphor vapors must be inhaled. The feet are simply too far from the nose and lungs for this to be effective.

What is the intended use of Vicks VapoRub?

The manufacturer recommends applying Vicks to the chest and throat to temporarily relieve cough and congestion associated with the common cold. It is also approved for soothing minor muscle aches.

Can Vicks on feet help with toenail fungus?

Yes, some studies suggest that the camphor, menthol, and eucalyptus oil in Vicks have antifungal properties that can help treat toenail fungus. Consistent, daily application is typically required to see results.

How does Vicks help with dry, cracked heels?

The petroleum jelly in Vicks acts as an excellent occlusive moisturizer, trapping existing moisture in the skin. Applying it at night and wearing socks can soften dry skin and help heal cracked heels.

Is it safe to use Vicks on children's feet for a cough?

No, Vicks VapoRub is not recommended for use on children under two years old due to the risk of camphor toxicity. Even for older children, it is best used as directed on the chest and throat.

What kind of foot pain can Vicks help with?

Can I use plain petroleum jelly for foot care instead of Vicks?
