Herbal remedies are the cornerstone of early healing arts and many people today still prefer using natural herbs and plants than taking prescription medications. Because herbs have medicinal properties, they also might produce adverse side effects. The milk thistle herb consists of seeds harvested from the Silybum marianum plant. The plant produces tall stems adorned with bright purple blooms and can be found along country roads and in fields and pastures. Before taking milk thistle, talk with your doctor about potential drug interactions, proper dosages and whether the herb is safe for you .
Milk Thistle
Native to Europe and the Mediterranean, milk thistle now is common in many parts of the world, including the United States. According to a Wilkes University document titled “Medical Attributes of Silybum Marianum – Milk Thistle,” the herb contains silibinin and silymarin, in addition to polyphenols and flavonolignans.
Uses
There is no indication that milk thistle is beneficial for treating or preventing headaches. Although medical studies are limited, milk thistle has other potential uses, including the treatment of liver and gall bladder disorders. The seeds also might be beneficial for increasing scant milk flow in breastfeeding women.
Headaches and Other Side Effects
According to MayoClinic.com, “Milk thistle appears to be well tolerated in recommended doses for up to six years.” While side effects are rare, they include headache. Other potential effects include itching, stomach upset, intestinal gas, loose bowel movements, joint pain, weakness and profuse sweating. Since studies on the safety of milk thistle are lacking, there might be additional side effects not yet known. If you’re taking milk thistle and getting headaches or experiencing any other unwanted physical effects, discontinue use and contact your doctor.
Additional Considerations
Do not take herbal remedies containing milk thistle if you have estrogen-sensitive cancer or are allergic to plants in the aster family. Milk thistle might reduce blood sugar levels, so people with low blood sugar or diabetes should consult their doctors before taking the herb, advises MayoClinic.com.
The FDA does not test most herbal remedies, and because studies on the safety of herbs are limited, there might be additional side effects not yet known.
