What is the primary benefit of Echinacea?

Echinacea is primarily known for its role in enhancing immunity. Research indicates that this herb can stimulate the immune system, which may help the body fight off infections more effectively, especially respiratory illnesses. The active compounds in Echinacea, such as alkylamides and polysaccharides, are thought to increase the production of white blood cells and other immune system components, leading to an overall boost in the body's defense mechanisms.

While some studies have explored Echinacea's other potential benefits, such as its effects on platelet aggregation or cognitive function, the evidence supporting these claims is not as robust as the research indicating its immune-enhancing properties. Additionally, any associations with sleep promotion are not generally emphasized in the context of Echinacea's primary uses. Thus, its most recognized and widely supported benefit remains its ability to enhance immunity.
