Why was DMSO banned?

DMSO: Rechtslage, Risiken und medizinische Grenzen – sachliche Einordnung und Sicherheit
DMSO (dimethyl sulfoxide) is a solvent that has been used in medicine and alternative medicine to treat a variety of ailments. However, while it is valued in some areas for its therapeutic properties, its use has been severely restricted or banned in many countries, including Germany. This raises the question: why was DMSO banned? To better understand this, it is important to take a look at the history, scientific background, and concerns that led to the regulation or banning of DMSO.

History of DMSO: From Hope to Skepticism

DMSO was originally discovered in the 1950s as a byproduct of paper manufacturing. It was initially used in industry as a solvent, but it was soon realized that it could have medical applications as well. In the 1960s, researchers began to investigate DMSO's potential as an anti-inflammatory and pain-relieving agent. The scientific studies raised hopes that DMSO could be a versatile and effective agent for treating pain, arthritis, sports injuries, and even skin conditions. Due to the initial promising research results, DMSO was hailed as a miracle cure by many doctors and alternative medicine practitioners. It was considered one of the few remedies that could not only relieve pain quickly, but was also relatively easy to use. Due to its ability to penetrate the skin, DMSO could be applied topically (on the skin), which made it very attractive for the treatment of muscle and joint pain.

safety concerns and side effects

However, the popularity of DMSO led to more intensive scientific scrutiny, and some concerns arose. Reports of side effects such as skin irritation, headaches, nausea and dizziness were documented. Of particular concern was that DMSO also caused severe eye problems in some cases. Animal studies showed that high doses of DMSO could cause cataracts in animals. This was a turning point, as eye problems were considered particularly risky. The fact that DMSO penetrates the body extremely quickly through the skin also made it problematic. When used together with other substances, there was a risk that harmful or toxic substances could also more easily enter the bloodstream. This property was a double sword: on the one hand, it made DMSO so effective, but on the other hand, it also opened up the risk of harmful chemicals being transported into the body.

lack of comprehensive studies

Another reason for the ban on DMSO was the lack of comprehensive clinical studies that could adequately demonstrate its effectiveness and safety. The science was still in its infancy, and although there were many anecdotes about the positive effects of DMSO, there was a lack of solid long-term studies that could confirm the substance's safety for humans. Without sufficient data on long-term use, it was difficult for health authorities to justify unrestricted approval of DMSO. In the 1960s and 1970s, the US Food and Drug Administration (FDA) studied DMSO and found that there was insufficient evidence to prove its safety for use in humans. This led to the FDA severely restricting the use of DMSO and only approving it for the treatment of certain conditions, such as bladder infection (interstitial cystitis).

Controversy over alternative medicine

The debate surrounding DMSO was further fueled by its increasing use in alternative medicine. Many alternative medicine practitioners were convinced of DMSO's effectiveness and used it for a wide range of ailments, from arthritis to cancer. These far-reaching claims, often without a solid scientific basis, led to further concerns from authorities. Because DMSO was readily available and many people used it without medical supervision, there was a risk of abuse or improper use. Self-medication with uncontrolled amounts of DMSO increased the risk of serious side effects. Authorities were therefore forced to take stricter measures.

Current applications and legal situation

Despite the concerns, DMSO is not completely banned in some countries, but continues to be used for certain medical applications. In the USA, for example, it is approved for the treatment of interstitial cystitis. In other countries, such as Germany, the use of DMSO in medicine is heavily regulated and often only permitted in special cases. DMSO is still used in veterinary medicine, particularly for the treatment of sports injuries in horses. Here it is used to relieve inflammation and pain, but under the strict supervision of a veterinarian.

Advantages and Disadvantages of DMSO

Advantages

  1. Anti-inflammatory effect : DMSO has been proven to reduce inflammation and pain. It has proven to be particularly effective in the treatment of arthritis and sports injuries.
  2. Rapid absorption : DMSO can be quickly absorbed through the skin, making it attractive for topical applications.
  3. Wide range of applications : Many people report positive effects in the treatment of muscle pain, joint pain and even skin conditions.

Disadvantages

  1. Eye problems : One of the most serious side effects of DMSO is the risk of eye problems, particularly the development of cataracts.
  2. Skin irritation and odor : DMSO can cause skin irritation, and many people find the characteristic garlic odor it produces unpleasant.
  3. Lack of long-term studies : There is still a lack of comprehensive long-term studies that demonstrate the safety of regular use of DMSO in humans.

Conclusion: Why was DMSO banned?

DMSO has been banned or heavily regulated in many countries for a number of reasons, including safety concerns due to eye problems, the lack of comprehensive long-term studies, and the potential risks of improper use. Although DMSO continues to be used in certain medical settings, it remains a controversial topic. Many users, particularly in alternative medicine, swear by its effectiveness, while the scientific community continues to insist on more solid data. For people considering using DMSO, it is important to do so only under medical supervision and to be aware of the potential risks. The use of DMSO shows that even seemingly promising substances require thorough and comprehensive research before they can be used without concern.
