What is feverfew primarily known for?

Feverfew is primarily known for its effectiveness in the prevention of migraines. This herb has been extensively studied for its ability to reduce the frequency and severity of migraine headaches. The active compounds in feverfew, such as parthenolide, are believed to contribute to its anti-inflammatory properties, which can help reduce the intensity of migraines and the associated symptoms. Many individuals suffering from chronic migraines have reported significant relief when incorporating feverfew into their treatment regimen.

The other options do pertain to various health benefits associated with different herbs or dietary practices but do not accurately reflect the primary use of feverfew. For instance, improving digestion is generally attributed to herbs like peppermint or ginger, boosting immune function is often linked to vitamins and other immune-supportive nutrients, and enhancing memory is more commonly associated with herbs like ginkgo biloba or rosemary. Therefore, while all these aspects relate to holistic wellness, feverfew's specific reputation as a migraine preventive is what sets it apart in this context.
