Top Medical Research Studies

We examined how silibinin, a compound found in milk thistle, affects allergic asthma in a mouse model. Our findings showed that silibinin significantly helped reduce airway inflammation and hyperresponsiveness, mainly by targeting the NF-κB pathway. This suggests that silibinin might offer protective benefits against allergic airway conditions by moderating inflammatory responses. While our research found promising results in mice, further studies are necessary to confirm its effectiveness in human asthma treatment.

Silibinin reduces allergy-related IgE
We explored the effects of silibinin on allergies by studying its impact on antibody production and T-cell responses in mice sensitized to ovalbumin. The mice received either no treatment or different doses of silibinin before being exposed to the allergen.

Our findings revealed that silibinin significantly reduced the levels of IgE antibodies, which are responsible for allergic reactions. Conversely, it boosted levels of IgG(2a), an antibody that can help fight off allergens.

Silibinin also shifted the immune response towards a balance that favors Th1 cells, which may provide a beneficial effect against allergies.

Silybine shows potential against allergies
We observed the effects of silybine, a key component derived from Silybum marianum seeds, on allergic reactions in rats. The study revealed that silybine can lower blood pressure and inhibit the severe responses associated with anaphylactic shock.

Notably, it appears to stabilize mast cell membranes, preventing the release of histamine—a major player in allergic reactions. However, while these findings are promising, it remains unclear how these effects translate to humans suffering from allergies.

Product caused irritation

While this Life Extension product is good quality, it caused my eyes to itch and become irritated. I have seasonal allergies, including to pollen, which may explain my reaction. I have used other milk thistle products without adverse effects. Although I was sensitive to this product, others may not have the same experience.

Silymarin aids UV skin protection
We explored how silymarin, a natural compound from milk thistle, impacts UV light-induced immune suppression and oxidative stress. Testing on mice showed that silymarin treatment significantly enhanced the skin's immune response, reducing harmful leukocyte infiltration and lowering levels of immunosuppressive cytokines.

Notably, silymarin also decreased the production of reactive oxygen species and nitric oxide linked to skin damage. Our findings suggest that silymarin could be a promising candidate for developing skincare products or sunscreens aimed at preventing skin cancer.
