Abstract Echinacea purpurea (L.) Moench (EP), a medicinal plant native to North America, is now cultivated in various regions including Europe. With increasing popularity of Korea recently, human clinical trial was conducted evaluate immune‐enhancing efficacy and safety EP 60% ethanolic extract (EPE) Koreans. Eighty volunteers were recruited for this randomized, double‐blind, placebo‐controlled trial. They randomly divided into two groups given either daily dose 200 mg EPE or placebo. All participants underwent testing Natural Killer (NK) cell cytotoxic activity, serum cytokine levels (IL‐2, IL‐6, IL‐10, IL‐12, IFN‐γ, TNF‐α), Wisconsin Upper Respiratory Symptom Survey‐21 (WURSS‐21), Multidimensional Fatigue Scale (MFS) during study assess changes outcomes. After 8 weeks consumption, significant increase NK activity compared the placebo observed. Additionally, IL‐2, TNF‐α also significantly increased following consumption. However, no observed WURSS‐21 MFS before after Throughout 8‐week period, adverse reactions reported relation there clinically diagnostic laboratory tests vital signs group. These results indicate that consumption could lead immune improvement without any effects. This first demonstrate beneficial effects on immunity Korean adults.

In recent years, plant polyphenols have become a popular focus for the development of novel functional foods. Polyphenols, class bioactive compounds, including flavonoids, phenolic acids, and lignans, are commonly found in plant-based diets with variety biological actions, antioxidant, anti-inflammatory, anticancer effects. Unfortunately, not widely used nutraceuticals since many chemicals possess poor oral bioavailability. Thankfully, can be encapsulated transported using bio-based nanocarriers, thereby increasing their Polyphenols' limited water solubility low bioavailability limiting factors practical usage, but this issue resolved if suitable delivery vehicles developed encapsulating delivering polyphenolic compounds. This paper provides an overview study nanocarriers enhancement polyphenol bioavailability, as well summary health advantages prevention treatment several diseases.
