Research indicates that silibinin, a compound derived from milk thistle, may have protective effects against allergies, particularly in allergic asthma and immune response regulation. In a mouse model of allergic asthma, silibinin was found to significantly reduce airway inflammation and hyperresponsiveness by targeting the NF-κB pathway, suggesting its potential as a therapeutic agent in managing allergic airway conditions [1]. Additionally, silibinin has shown promise in balancing immune responses by decreasing IgE antibody levels, which are typically linked to allergic reactions, while increasing IgG(2a) levels that may help combat allergens [2].
Another study highlighted the effects of silybine, a key component of Silybum marianum, in mitigating allergic reactions in rats, including stabilization of mast cell membranes, thereby reducing histamine release which is crucial in allergy pathways [4]. Despite these encouraging findings, it's important to note that most research has been conducted on animal models, necessitating further studies in humans to comprehensively understand the implications and effectiveness of these compounds in allergy treatment.
