Leisha Dimethyl sulfoxide, better known as DMSO, is one of the most unusual compounds ever explored in biology. For decades it has appeared in thousands of scientific papers and has been studied across many areas of physiology and medicine. Most of us don’t know about DMSO and I am not sure why science didn’t continue deep research based upon what they discovered? Perhaps there wasn’t enough money to be made?
The most interesting thing about DMSO is not simply what the compound does. The deeper story is what it represents. DMSO belongs to a family of sulfur compounds, and sulfur is one of the great hidden threads connecting soil, plants, microbes, animals, and human physiology.
That “thread” is what I am all about and when I follow that thread, the compound begins to make much more sense. So, let’s start with the soil.
The Sulfur Story Beneath Our Feet
In living soil, sulfur is constantly moving through microbial communities. Bacteria and fungi convert sulfur from one form to another, making it available to plants and then releasing it again as organic matter breaks down.
In a healthy soil food web sulfur never sits still. It circulates through compost, root zones, decaying leaves, mineral particles, and the breath of microorganisms. This elemental movement supports enzymes, proteins, plant defenses, and metabolic resilience.
Plants absorb sulfur from this microbial landscape and weave it into their own chemistry.
Many of the most biologically active plant compounds contain sulfur or depend on sulfur-driven pathways for their synthesis. These molecules contribute to aroma, defense, signaling, and resilience. They help plants manage stress, repel threats, and maintain metabolic balance.
When humans consume those plants, sulfur enters our own biological systems.
Sulfur in the Human Terrain
Inside the body sulfur participates in an extraordinary range of biological processes.
It supports detoxification pathways in the liver. It contributes to the production of glutathione, one of the body’s most important molecules for maintaining redox balance. It helps build connective tissue, cartilage, skin structure, and cellular membranes.
Sulfur also participates in sulfation pathways that help process hormones, neurotransmitters, and metabolic byproducts.
When sulfur metabolism functions well, the body maintains fluid movement, cellular repair, and metabolic stability.
When sulfur metabolism becomes strained, the terrain often begins to feel congested, inflamed, and energetically depleted.
This is the biochemical landscape into which DMSO enters.
What Makes DMSO Unique
DMSO is a small sulfur molecule with an unusual ability to pass through biological membranes. Skin, connective tissue, and cellular barriers allow it to move through them with remarkable ease.
Because it dissolves both water-soluble and fat-soluble molecules, DMSO can move between biological environments that normally remain somewhat separate. It can enter tissues quickly and distribute widely throughout the body.
DMSO also interacts with oxidative chemistry in cells because it can neutralize certain highly reactive oxygen molecules that are produced during injury, inflammation, or metabolic stress. These reactive molecules, often called reactive oxygen species, can damage cell membranes, proteins, and DNA when they accumulate in excess. By helping stabilize these reactions, DMSO may reduce some of the secondary cellular damage that occurs when tissues are under stress.
These characteristics led researchers to explore DMSO in many contexts including burns, neurological injury, connective tissue disorders, circulation challenges, and metabolic stress.
A Compound That Changes the Terrain
DMSO does not behave like a narrow pharmaceutical designed to target a single pathway.
Instead, it influences the environment in which cells operate.
It affects membrane permeability, circulation, oxidative chemistry, and transport of molecules between tissues. In other words, it modifies the terrain rather than acting as a single-point intervention.
This ecological perspective makes the compound easier to understand.
Just as degraded soil does not fail because of one missing element, stressed tissue rarely struggles because of a single pathway. Circulation, oxygen delivery, cellular energy, fluid movement, and signaling all interact together.
DMSO appears to influence several of these factors simultaneously.
Sulfur, Microbes, and the Inner Ecosystem
The microbiome adds another important layer to this story.
Both soil ecosystems and the human gut rely heavily on sulfur chemistry. In living soil, microbes constantly transform sulfur into different forms, making it available to plants and keeping nutrients moving through the ecosystem. A similar process happens inside the human body.
In the gut, microbes interact with sulfur-containing nutrients that come from the foods we eat. These compounds help support the lining of the digestive tract, maintain the protective mucus layer of the intestines, and assist the body in managing oxidative stress.
When these sulfur pathways are working well, they support communication between microbes and human cells, helping regulate metabolism, immune balance, and tissue repair.
In this way sulfur metabolism becomes a bridge between microbial ecology and human physiology. The same elemental chemistry that moves through soil and plants continues its work inside the body.
DMSO, as a sulfur-based compound that moves easily through tissues, interacts with this ancient biochemical system that links microbes, plants, and human biology.
DMSO and Plant Medicine
One of the most fascinating properties of DMSO is its ability to carry small molecules with it as it moves through tissues.
Many plant compounds have remarkable biological activity but are sometimes poorly absorbed or slow to reach deeper tissues. Polyphenols, flavonoids, terpenes, and other botanical compounds can interact with cellular signaling pathways, but their penetration into tissues may be limited.
Because DMSO moves through membranes so readily, it can act as a carrier that allows some of these compounds to reach deeper layers of tissue more effectively.
This property has drawn interest from researchers and herbalists exploring ways that plant compounds interact with human physiology.
Herbs and foods rich in biologically active compounds such as turmeric, resins, aromatic herbs, and certain medicinal mushrooms contain molecules that influence oxidative balance and cellular signaling. When those molecules reach tissues more efficiently, their interaction with the cellular environment may become more pronounced.
So, let’s consider this in Cancer metabolism and how it is closely connected to redox imbalance and altered cellular energy production.
Many cancer cells shift their metabolism toward glycolysis even when oxygen is present. This phenomenon, often called the Warburg effect, creates a cellular environment characterized by altered energy flow, oxidative stress, and disrupted communication between cells.
In this terrain several factors become especially important.
Circulation
Oxygen delivery
Mitochondrial energy production
Redox balance
Cellular signaling
DMSO interacts with several of these elements simultaneously.
Research has explored how DMSO influences oxidative stress, cellular signaling, and membrane transport. In laboratory settings it has also been observed to encourage certain abnormal cells to differentiate into more mature cell forms. It stops the cancer cells from developing. Differentiation means the cells begin behaving more like normal tissue rather than remaining in an aggressive, primitive metabolic state.
Within a terrain-based perspective, these effects suggest that DMSO may help support shifts in metabolic environments toward improved cellular communication and stability.
The Modern Sulfur Gap
Another part of this story relates to diet.
Modern agricultural systems often provide less sulfur than traditional diets once did. Many agricultural soils have experienced reductions in sulfur availability, and modern fertilizers frequently emphasize nitrogen, phosphorus, and potassium while neglecting sulfur and trace minerals.
Plants grown in depleted soils may therefore contain lower levels of sulfur-containing compounds. Sulfur is required to build amino acids such as methionine and cysteine. These amino acids support glutathione production, detoxification enzymes, connective tissue, and numerous metabolic pathways.
When sulfur intake is limited or when digestion and microbial metabolism are compromised, sulfur-related processes in the body can weaken.
Using DMSO Carefully
Because DMSO penetrates the skin and moves into tissues easily, it must be used with care and cleanliness.
Anything present on the skin can potentially be carried into the body along with it.
For that reason the skin should always be washed thoroughly with clean water before application. No lotions, perfumes, or chemicals should be present on the area.
Most people explore DMSO in diluted form. Solutions between about 50 percent and 70 percent are commonly used for topical applications. When first becoming familiar with the compound, some individuals choose to begin with even lower concentrations.
A few practical guidelines are widely followed by those who use it.
- Use only high-purity DMSO intended for biological use.
- Apply to clean skin.
- Start with small amounts.
- Observe how the body responds.
- Avoid applying to irritated or damaged skin.
Some people also explore combining DMSO with herbal extracts or mushroom preparations. The interest in this approach comes from one of the compound’s most unusual characteristics. DMSO moves through biological membranes very easily and can carry small dissolved molecules with it as it passes into tissues.
Many medicinal plants and fungi contain biologically active compounds such as polyphenols, terpenes, flavonoids, and other metabolites that influence cellular signaling, oxidative balance, and immune communication. When these compounds are taken orally, they must pass through digestion, absorption, and metabolism before reaching tissues throughout the body. Some are absorbed easily, while others are only partially absorbed.
Because DMSO can move through tissues rapidly, some people believe it may help transport certain plant compounds more efficiently through the body. This idea has led to interest in combining small amounts of DMSO with herbal teas, tinctures, or mushroom preparations.
Medicinal mushrooms such as reishi, chaga, or turkey tail contain complex polysaccharides, triterpenes, and phenolic compounds that interact with immune signaling and oxidative balance. Herbal preparations such as turmeric, ginger, or resins also contain molecules that influence inflammatory pathways and cellular communication.
When people experiment with combining these preparations with DMSO, the goal is not to replace the plants themselves but to potentially improve the movement of some of their smaller active compounds through tissues.
However, because DMSO carries substances with it, simplicity and cleanliness become important. Preparations are usually kept simple and free from unnecessary additives, and only clean water-based extracts or alcohol tinctures from trusted sources are typically considered.
Another important point is that many of the larger molecules in mushrooms and herbs, such as polysaccharides, are too large to be transported directly by DMSO. In those cases the compound may not carry the large molecules themselves but could still influence circulation or membrane permeability in ways that support the body’s response to those compounds.
For this reason, when people explore this approach they generally use small amounts of DMSO, keep herbal preparations simple, and observe carefully how their body responds.
A temporary garlic-like scent on the breath or skin is common after use. This occurs because the body metabolizes DMSO into sulfur compounds that are released through respiration and sweat.
A Molecule That Points Back to the Soil
Perhaps the most important lesson from DMSO is not about the compound itself. It is about sulfur.
Sulfur is one of the elemental languages of life. It runs through microbial metabolism in the soil, through plant chemistry, through human detoxification pathways, through mitochondrial function, and through the repair of tissues after stress.
The same sulfur cycles that stabilize forest soils and nourish plants continue quietly within our own bodies. DMSO simply highlights that ancient connection.
When viewed through a soil-to-human lens, the compound becomes less mysterious. It is part of the same sulfur story that begins beneath our feet in living soil and continues upward through plants, food, microbes, and human physiology.
The chemistry of life did not begin in a laboratory. It began in the soil.
And every time we restore the vitality of soil, nourish ourselves with living foods, and reconnect with the microbial ecosystems that sustain life, we participate again in that ancient elemental cycle. Sulfur is one of the quiet threads holding that cycle together.
DMSO simply reminds us that the conversation between soil, plants, microbes, and human health has never stopped.
