Silybin shows promise for autoimmune disorders
We investigated how silybin, a unique flavonoid found in certain plants, impacts autoimmune disorders, specifically using a model for multiple sclerosis called experimental autoimmune encephalomyelitis (EAE).

In our study, silybin significantly reduced disease severity, inflammation, and damage to the central nervous system (CNS) in EAE mice.

The findings suggest that silybin works by inhibiting the activation of dendritic cells and reducing harmful Th17 cell differentiation. This positions silybin as a promising candidate for new treatments aimed at autoimmune diseases like multiple sclerosis.

Silibinin shows immunosuppressive effects
We explored the effects of silibinin, derived from silymarin (Silybum marianum), on autoimmune disorders, particularly multiple sclerosis. In a study using an animal model, we observed that silibinin notably reduced signs of spinal cord damage and inflammation, suggesting its potential immunosuppressive effects.

Additionally, silibinin was found to modulate cytokine production by lowering pro-inflammatory Th1 cytokines while increasing anti-inflammatory Th2 cytokines. This indicates that silibinin could be both immunosuppressive and beneficial for managing autoimmune responses, though further research is necessary to confirm its effectiveness in clinical settings.

Silibinin shows promise in autoimmunity
We explored how silibinin, a compound derived from milk thistle, may influence autoimmune disorders like rheumatoid arthritis (RA).

Through our study, which included both healthy individuals and RA patients, we found that silibinin enhances the expression of estrogen receptor beta (ERβ) and promotes apoptosis in T lymphocytes, leading to reduced inflammation.

It also acts on microRNA-155, which is linked to RA's progression. These findings suggest that silibinin holds promise as both a treatment option and a dietary supplement for managing autoimmune diseases.

Significant improvement
7 people found this helpful
The delivery to the UK via DHL arrived early, which was great. This is the second time I have tried Gaia Herbs Milk Thistle. The first time I used it was due to severe vertigo that left me bed bound for months, prompted by a dream that claimed “it was poison and to get milk thistle”! Gaia Herbs boasted the best reviews concerning liver lab reports, so I decided to try it. After one bottle of 120 capsules, I felt much better, and by the second bottle, I was no longer dizzy. Now, three years later, I ordered more from this company, which was delivered very quickly. Thank you very much.

Supports liver health
Excellent product! This is my second order. Gaia is a trusted brand known for excellent quality and ingredients. Milk Thistle supports liver health and aids in detoxification. My abdominal discomfort disappeared after taking three capsules of this supplement, which was the first benefit I noticed. I will continue buying it from iHerb.

Silymarin boosts insulin production
We analyzed how Silymarin affects the Pdx1 gene expression and insulin production in a model of diabetes following partial pancreatic removal. With 72 rats divided into groups, those treated with Silymarin showed significant increases in both Pdx1 and insulin levels compared to untreated rats.

Notably, the treatment led to a remarkable boost in β-cell proliferation, enhancing insulin secretion and reducing blood sugar levels. These findings highlight Silymarin's potential to support the recovery of insulin-producing cells in diabetic conditions.

We explored the impact of silymarin, a compound from milk thistle, on the immune system in patients with multiple sclerosis (MS). By isolating Th1 cells from both newly diagnosed and treatment-receiving patients, we assessed how silymarin affected cell activity at various doses and times.

Our results indicated that silymarin effectively reduced Th1 cell proliferation and interfered with the production of key inflammatory markers. However, in patients treated with interferon-beta, there were mixed results over time, where some increases in inflammatory markers were noted. Overall, silymarin appears to hold promise as an immunomodulatory agent for MS.

Silymarin shows promise for RA
In our research, we examined the effects of silymarin (Livergol®) on rheumatoid arthritis (RA) in a small group of 44 stable patients. After 90 days of treatment, we noticed a significant decrease in the Disease Activity Score (DAS-28), which assesses inflammation levels. Specifically, patients reported improvement in their symptoms, suggesting potential anti-inflammatory benefits from silymarin due to its antioxidant properties. However, the exact ways it works remain unclear, highlighting the need for more extensive studies with cytokine measurement to unravel its mechanisms further.
