Organic Echinacea Purpurea Seed Extract

Also known as: Purple coneflower, Eastern purple coneflower, Echinacea, Coneflower, Echinacea purpurea

Overview

*Echinacea purpurea* is a flowering plant native to North America, renowned for its immunomodulatory and anti-inflammatory properties. Extracts are derived from the roots, flowers, and seeds of the plant and are primarily employed for preventing and treating upper respiratory tract infections (URTIs) like colds and flu. The health benefits are attributed to its bioactive compounds, including alkamides, glycoproteins, polysaccharides, and caffeic acid derivatives (CADs). Despite numerous studies showcasing its efficacy, the research findings are mixed, with significant benefits presented in some studies and inconclusive results in others, highlighting variability in its evidence base. This supplement is commonly available in various forms, including capsules, tinctures, and teas, making it accessible for a broad audience seeking natural immune support.

Benefits

Research shows that *Echinacea purpurea* extracts significantly reduce the frequency and duration of URTIs. A systematic review indicated a 38% reduction in nasal symptoms, with children experiencing a notable 55% decrease in illness episodes. Furthermore, the extract demonstrates anti-inflammatory properties by impacting the PI3K/Akt pathway and activating immune cells like macrophages and natural killer cells. The strongest effects are notably seen in children, with moderate evidence supporting efficacy in adults, especially when treatment commences early. However, evidence regarding its preventive effects remains inconsistent, necessitating further investigation.

How it works

*Echinacea purpurea* exerts its effects primarily through immunomodulation, which improves both innate and adaptive immune responses. The extract promotes the activation of macrophages and natural killer cells while modulating cytokine production, enhancing overall immune function. Its anti-inflammatory properties are connected to the inhibition of inflammatory mediators via pathways such as PI3K/Akt, and its bioactive components directly interact with immune cells, aiding in the regulation of inflammation and immune responses.

Side effects

When utilized according to the recommended guidelines, *Echinacea purpurea* is generally regarded as safe. However, mild gastrointestinal symptoms, headaches, and allergic reactions may occur in over 5% of users. Although severe allergic reactions, such as anaphylaxis, are rare, caution should be taken, especially for individuals on immunosuppressive medications. It is advisable for patients with autoimmune disorders to avoid this supplement due to potential exacerbation of their condition. Pregnant women and children should use *Echinacea purpurea* only under medical supervision due to limited safety data, ensuring proper assessments of risks are undertaken.

Dosage

The typical dosage for *Echinacea purpurea* ranges from 300 to 500 mg daily of a standardized extract, often recommending 2-3 doses per day for the prevention of URTIs. Although the minimum effective dose requires further research, exceeding 1000 mg daily is generally discouraged due to insufficient safety data at high levels. Continuous supplementation over several weeks may enhance preventive benefits, particularly with alcohol-based extracts which provide improved bioavailability compared to their water-based counterparts.
