# Alternative treatment methods for primary sclerosing cholangitis
Ursodeoxycholic acid (UDCA)
Ursodeoxycholic acid is a bile-like acid that normally occurs in small amounts in the body. In PSC it is administered in higher concentrations based on the idea that it can improve bile flow and suppress inflammatory cells.
ResearchediPositive results in clinical studies, not yet standard treatment
Multiple clinical studies have examined UDCA, with mixed results. Lower doses (up to approximately 15 mg per kg body weight per day) show no clear benefit on disease progression. Higher doses are under investigation, but the findings have not been consistent enough so far to allow broad recommendation. Many clinicians are closely monitoring developments here, because the mechanism is theoretically logical, but practical value has not yet been established.
Immunosuppressive agents
Because PSC is strongly associated with inflammation and immune system abnormalities (especially in connection with inflammatory bowel disease), medications that weaken the immune response are sometimes used.
ResearchediPositive results in clinical studies, not yet standard treatment
Substances such as azathioprine, mycophenolate and corticosteroids have been tested in smaller studies. The results suggest that these agents may possibly improve inflammatory markers, but there is no strong evidence that they stop the progression of liver damage itself. They come into consideration mainly when PSC is accompanied by autoimmune hepatitis or when inflammatory markers are severely elevated. They do have side effects that must be carefully monitored.
Green tea and polyphenols
Green tea contains strong antioxidants, especially catechins, which can reduce inflammation in laboratory studies. This has attracted attention in PSC research.
ResearchediPositive results in clinical studies, not yet standard treatment
Some positive effects have been observed in animal studies, and clinical research into its value is ongoing. Important to know: green tea can (especially in concentrates) interact with immunosuppressive agents and other medicines — a recent case showed that intensive green tea use could lead to high levels of certain immunosuppressive agents. This illustrates that "natural" is not automatically safe. Currently this is still considered experimental territory; there is no standard protocol for PSC patients.
Astragalus and saponins
Astragalus is a plant from traditional Chinese medicine. Recent animal studies are investigating whether certain extracts (particularly total saponins from astragalus) can reduce inflammation in PSC via a specific immunological mechanism (TGR5 pathway).
ExperimentaliOngoing in study setting, outcome still unknown
This research is still entirely in the animal experimental phase. No human clinical trials for PSC are known. Astragalus may also interact with immunosuppressive agents. This is interesting for future research, but not a treatment strategy for now.
Herbal remedies and traditional herbs
Various herbal remedies (milk thistle, globe artichoke, turmeric, et cetera) are used in traditional medicine for liver disorders and are also being investigated for PSC.
ResearchediPositive results in clinical studies, not yet standard treatment
Some review articles have described potential mechanisms by which certain herbs could reduce inflammation or liver cell damage. However: for PSC specifically, there are virtually no high-quality randomized clinical trials. Most of the data are from laboratory work. Moreover: some herbs can have strong effects on the liver (their active ingredient itself can damage the liver), and the purity and dosage of commercial herbs vary widely. Combination with regular medicines requires caution.
Probiotics and microbiome intervention
The gut microbiome plays a role in immune regulation and can indirectly influence liver inflammation, especially since PSC is often accompanied by inflammatory bowel disease.
ResearchediPositive results in clinical studies, not yet standard treatment
There is cautious research into certain probiotic strains in PSC. To date, studies show no strong effects on disease progression, but possible improvements in certain inflammation markers. This is not yet a standard treatment. However: patients with PSC and bowel disease sometimes benefit from general bowel monitoring (nutrition, microbiota-friendly factors), separate from the PSC itself.
Vancomycin (oral, systemically non-absorbed)
Oral vancomycin acts primarily in the gut and is sometimes investigated in combination with PSC and bowel disease, because it can suppress certain harmful bacteria.
ResearchediPositive results in clinical studies, not yet standard treatment
Some clinical observations suggest that oral vancomycin may help some patients, but large clinical trials are lacking. It is an expensive medication and works only in the gut. For systemic effect on the liver, benefit has not been demonstrated. This may play a supportive role in bowel disease management, but not as treatment for PSC itself.
Fecal microbiota bundle (fecal transplantation)
Fecal transplantation introduces healthy gut bacteria. Researchers are investigating this based on the idea that an altered microbiome in PSC contributes to the disease.
ExperimentaliOngoing in study setting, outcome still unknown
There are some case reports and early investigations started, especially where PSC and inflammatory bowel disease coexist. It is not a standard treatment and is used in the Netherlands only in a research setting. Effects on PSC itself (not just bowel disease) have not yet been demonstrated.
Complementary treatments: acupuncture, meditation, dietary modifications
These approaches are based on the idea that they improve general well-being and possibly reduce inflammation.
UnproveniNo scientific evidence that it works
There is no valid scientific evidence that acupuncture, meditation, or specific diets can slow PSC progression itself. However: they can help manage pain, fatigue, and stress, which may improve quality of life. These are supportive measures, not treatment of the disease itself. Nutrition plays a role in overall health; a dietitian can help (for example with malnutrition or fat malabsorption), but no specific PSC diet is scientifically valid.
Pentoxifylline
This is a medication that can improve rheological (blood flow) properties and reduce inflammation.
ResearchediPositive results in clinical studies, not yet standard treatment
Some small studies have suggested potential benefits, especially on inflammation markers. However: larger studies are lacking, and the evidence is not strong enough to recommend it routinely. It is sometimes considered in specific clinical situations, but this requires discussion with your clinician.
Medications with active research but not yet approved
Various pharmaceutical companies are developing new medications targeting specific inflammatory pathways or fibrosis inhibition in PSC. Some of these (for example certain toll-like-receptor antagonists) are in clinical phase. These are strictly experimental and available only through research protocols.
