Milk thistle, an herb with a rich history in traditional medicine, has gained popularity worldwide for its potential benefits, particularly in supporting liver health. However, as with any supplement or herbal remedy, it is crucial to consider both the advantages and disadvantages before adding it to your regimen. This article aims to delve into the potential downsides of taking milk thistle, ensuring that consumers make informed decisions about their health.
Introduction to Milk Thistle
Milk thistle, scientifically known as Silybum marianum, is a plant native to the Mediterranean region. It has been used for centuries for its medicinal properties, primarily for treating liver and gallbladder disorders.
