DMSO For External Use

DMSO For External Use

Posted by Jewel on Mar 12, 2026

As interest in natural remedies continues to grow, many pet parents are exploring supportive tools that work in harmony with the body rather than against it. One substance that has quietly remained part of the natural health conversation for decades is DMSO, known for its ability to move easily through tissues and support the body’s response to inflammation and irritation. When thoughtfully combined with the gentle antimicrobial qualities of colloidal silver, the result is a simple but powerful topical formula. Our new SilverRemedy DMSO/Silver Gel was created with this idea in mind, a clear, smooth gel designed for easy external use on pets, bringing together pharmaceutical-grade DMSO and high-quality colloidal silver in a clean, straightforward preparation that supports the skin and tissues while staying aligned with the holistic principles of natural pet care

We also love DMSO/Silver conbination for eye use in our Eye Ulcer Drops  for Dogs and Cats  as well.

Dimethyl Sulfoxide, commonly known as DMSO

Is a substance that has fascinated researchers, doctors, and holistic health communities for decades. It is often talked about in natural health circles because of its unusual ability to move through the body very easily and carry other substances with it. Because of this unique quality, many people are curious about how it works and whether it can be used internally.

For those exploring holistic health, it is helpful to understand what DMSO is and why it has gained attention over the years.

DMSO is a naturally occurring compound derived from lignin, which is a substance found in trees and wood pulp. It was first identified in the 1800s but began gaining serious scientific attention in the 1960s when researchers discovered its remarkable ability to pass through the skin and biological membranes. Unlike many compounds that remain localized in the digestive tract or bloodstream, DMSO can move through tissues and distribute throughout the body very rapidly.

Because of this property, scientists began studying it for its ability to transport molecules into cells. It also demonstrated strong anti-inflammatory and antioxidant properties in laboratory and clinical research. These qualities led to decades of investigation into its potential therapeutic uses.

In human medicine, DMSO is officially approved in the United States for one condition called interstitial cystitis, a painful bladder disorder. Outside of that specific use, most other applications have remained experimental, alternative, or off-label.

In many other countries, however, physicians have explored broader uses.

One of the reasons DMSO has drawn interest is its powerful anti-inflammatory effect. Inflammation is involved in many chronic health problems, including joint pain, nerve irritation, and tissue injury. DMSO appears to help reduce inflammatory signaling and oxidative stress within tissues. It also has the ability to scavenge free radicals, which are unstable molecules that can damage cells.

Another unique characteristic is its ability to increase circulation and improve tissue oxygenation.

Some researchers believe that DMSO helps cells exchange oxygen more efficiently, which may explain why it has been explored for injuries, muscle recovery, and nerve health.

DMSO also has antimicrobial properties.

Studies have shown it can inhibit certain bacteria, fungi, and viruses in laboratory environments. In holistic health discussions, this property is sometimes mentioned in relation to immune support and infection control, although more research is still needed to understand these effects fully.

Perhaps the most well-known feature of DMSO is its role as a carrier or transporter.

It can move other molecules through tissues and into the bloodstream. This is why it has been studied as a delivery system for medications. However, this same property is also the reason people must be extremely cautious with it.

Because DMSO carries substances into the body, anything mixed with it or present on the skin may also be transported into the bloodstream. This means impurities, chemicals, pesticides, or medications could potentially be carried along with it. For this reason, purity and proper handling are extremely important.

When people discuss internal use of DMSO, they are generally referring to oral consumption diluted in water.

Historically, some physicians experimented with this approach in controlled research settings. Reports suggested possible benefits related to inflammation, circulation, and pain reduction. However, these uses remain controversial and are not widely accepted within conventional medicine.

There are also potential side effects to be aware of. Some individuals experience headaches, digestive upset, dizziness, or fatigue when using DMSO internally. One commonly reported effect is a garlic-like taste or odor on the breath and skin. This occurs because the body metabolizes DMSO into a compound called dimethyl sulfide.

Because DMSO is rapidly absorbed and distributed throughout the body

Dosage and purity become extremely important considerations. Pharmaceutical grade DMSO is required for any medical research or pet and human use. Industrial grades of DMSO may contain contaminants that are not safe for internal exposure.

In the world of natural health, discussions about DMSO often focus on its ability to support the body’s own healing processes rather than acting as a traditional drug. Many holistic practitioners view it as a compound that helps reduce inflammation and improve cellular communication.

DMSO has been used externally for horses since the 1960s, so it has more than 60 years of veterinary history, especially in equine medicine.

In the early 1960s researchers began studying DMSO because of its unusual ability to pass through skin and reduce inflammation. But this has been mostly for external use. 

When it comes to our pets for internal use, the situation becomes even more complex. Animals metabolize substances differently than humans, and research on internal DMSO use in pets is very limited. Because of these unknowns, internal use is not something we can give advice about for dogs or cats.

Our approach at Holistic Pet Care focuses on gentle, supportive natural remedies that align with the body’s own healing systems and do recommend it in our eyedrops and gel. While DMSO has  amazing healing properties and continues to be studied, internal use for pets falls outside the scope of what we can recommend. While we do recommend doing your own research.

Education is very valuable

Understanding the science behind substances like DMSO helps pet guardians make more informed choices and better understand the conversations happening in holistic health communities.

Many people first encounter DMSO through topical applications, where it has been used historically for inflammation, injury support, and circulation. Topical use has been studied much more extensively than internal use and is generally the area where most experience and research exist.

As with any powerful substance, thoughtful research and caution are important. Holistic health is not about using every natural compound available. It is about choosing tools that support the body’s natural intelligence in the safest and most balanced way possible.

Learning about DMSO can be part of that education. But when it comes to caring for our animals, simplicity, safety, and respect for their natural physiology remain the guiding principles.
