Greenherb supplies a premium, scientifically-validated Echinacea Purpurea Extract, derived from the aerial parts and roots of Echinacea purpurea (L.) Moench, a native North American flowering plant with one of the strongest evidence bases for immune support among medicinal herbs. Our echinacea purpurea extract is carefully processed from organically cultivated coneflower (the plant's common name) to preserve the full spectrum of bioactive compounds, including alkylamides, cichoric acid, polysaccharides, and echinacoside. This potent, standardized echinacea purpurea extract powder delivers clinically-supported benefits for immune system modulation, upper respiratory health, and seasonal wellness, offering a time-honored botanical with extensive modern clinical validation for global nutraceutical, functional food, and dietary supplement markets.
We support global B2B customers with consistent quality, scalable supply, and comprehensive analytical documentation, enabling the development of evidence-based products that leverage this premier immune-supporting herb.
Standardized for Clinically-Active Alkylamides & Cichoric Acid – Our echinacea purpurea extract is precisely standardized to guarantee consistent levels of alkylamides (typically 2-5%) and cichoric acid (typically 4-8%), the two primary bioactive marker compounds responsible for its immunomodulatory, anti-inflammatory, and antiviral properties .
Extensive Clinical Validation for Immune Health – Echinacea purpurea is one of the most researched medicinal plants in the world, with over 30 human clinical trials and numerous meta-analyses confirming its effectiveness in reducing the duration and severity of upper respiratory tract infections, as well as supporting overall immune function when taken preventively .
Dual-Component Extraction from Both Aerial Parts & Roots – Our echinacea purpurea root extract is combined with aerial part extract to capture the complementary bioactive profiles: roots are richer in alkylamides (immune-activating), while aerial parts contain higher levels of cichoric acid and polysaccharides (antioxidant and immune-supporting) .
Clinically-Proven Upper Respiratory Support – Multiple randomized, double-blind, placebo-controlled trials have demonstrated that echinacea purpurea supplementation significantly reduces the risk of developing colds, shortens illness duration by 1-2 days, and alleviates symptom severity including sore throat, cough, and nasal congestion .
Potent Immunomodulatory Mechanism – Unlike simple immune stimulants, echinacea purpurea works through a sophisticated immunomodulatory mechanism—activating macrophages, enhancing natural killer (NK) cell activity, and upregulating cytokines when immune challenge is present, while supporting immune balance during normal conditions .
Rich in Natural Antioxidant Compounds – Cichoric acid and other caffeic acid derivatives provide powerful free radical scavenging activity, protecting cells from oxidative stress and supporting the body's natural inflammatory balance during immune challenges .
Sustainably Sourced & Grown in North America – Our echinacea purpurea is cultivated in its native North American regions (US Midwest and Canada), where the plant thrives in open fields without excessive pesticide use, ensuring optimal bioactive compound development and sustainable agricultural practices .
Greenherb's Echinacea Purpurea Extract captures the immune-supporting power of a plant that has been used by Native Americans for centuries and has become one of the most scientifically-validated medicinal herbs in modern Western herbalism. Known commonly as coneflower for its distinctive purple petals, echinacea purpurea occupies a unique place in natural medicine—it is one of the few herbs with consistent positive outcomes across numerous high-quality clinical trials for reducing the frequency, duration, and severity of common colds and upper respiratory infections . What makes echinacea particularly valuable is its sophisticated immunomodulatory mechanism: rather than simply "boosting" the immune system indiscriminately, it primes immune cells to respond more efficiently when a pathogen is present, while supporting inflammatory balance during times of health . Our echinacea purpurea extract powder captures the complementary bioactives from both aerial parts (rich in cichoric acid) and roots (rich in alkylamides), delivering a full-spectrum, clinically-relevant ingredient for immune wellness. It is the ideal choice for brands developing advanced products in the immune support, seasonal wellness, and upper respiratory health categories.
Botanical Source: Echinacea purpurea (L.) Moench (Purple Coneflower)
Used Part: Aerial parts (flowers, leaves, stems) and/or root, depending on specification
Key Active Components: Alkylamides (dodeca-2E,4E,8Z,10E/Z-tetraenoic acid isobutylamides), Cichoric acid (chicoric acid), Echinacoside, Polysaccharides (inulin-type fructans), Caffeic acid derivatives (caftaric acid, chlorogenic acid) .
Standardization: Available standardized to alkylamides (2%, 3%, 5%) or cichoric acid (4%, 6%, 8%), with full polysaccharide profile .
Appearance: Fine, light greenish-brown to olive-green powder with characteristic earthy, slightly sweet aroma
Flavor: Mildly bitter, herbaceous, with echinacea's distinctive "tingling" sensation from alkylamides
Solubility: Water-soluble extract options available; alkylamides are lipophilic, so hydroethanolic extraction provides optimal profile
Extraction Ratio: Available in various ratios (4:1, 10:1, 20:1) and as standardized extracts
Our process is optimized to preserve the delicate alkylamides and heat-sensitive caffeic acid derivatives:
Sustainable Cultivation & Harvest: Echinacea purpurea is cultivated in its native North American regions. Aerial parts are harvested at peak flowering (mid-summer), while roots are harvested after 3-4 years of growth when alkylamide content is maximal .
Cleaning & Drying: Plant material is carefully washed, sorted, and gently dried at low temperatures (below 40°C) to preserve heat-sensitive alkylamides and cichoric acid .
Size Reduction: Dried material is milled to a uniform particle size to optimize extraction efficiency.
Hydroethanolic Extraction: Utilizes a precisely calibrated ethanol-water solvent system (typically 50-60% ethanol) to efficiently extract both water-soluble polysaccharides and cichoric acid, along with lipophilic alkylamides .
Filtration & Concentration: The crude extract is filtered to remove insoluble plant debris and concentrated under vacuum at low temperatures to prevent degradation of thermolabile compounds.
Purification & Standardization: The concentrated extract is analytically tested using HPLC to quantify alkylamide and cichoric acid content, then blended to achieve guaranteed, consistent levels of target markers .
Spray Drying: The standardized liquid is spray-dried into a fine, free-flowing echinacea purpurea extract powder using gentle inlet temperatures and a food-grade carrier (such as maltodextrin) when needed.
Comprehensive Quality Verification: Each batch undergoes rigorous HPLC analysis for alkylamide and cichoric acid content, along with testing for heavy metals, microbial safety, and residual solvents.
Echinacea Purpurea Extract is utilized for its scientifically-documented, clinically-validated immune benefits:
Reduces Duration & Severity of Upper Respiratory Infections*: Multiple meta-analyses of randomized controlled trials demonstrate that echinacea purpurea supplementation significantly shortens the duration of colds by 1-2 days, reduces symptom severity, and decreases the risk of recurrent infections .
Supports Immune System Modulation*: The alkylamides in echinacea purpurea bind to cannabinoid receptor CB2 on immune cells, modulating cytokine production and enhancing the activity of macrophages and natural killer (NK) cells, while polysaccharides stimulate phagocytosis .
Provides Preventative Immune Support*: When taken during cold and flu season, echinacea purpurea has been shown to reduce the incidence of upper respiratory tract infections by approximately 20-30% compared to placebo .
Promotes Healthy Inflammatory Balance*: Cichoric acid and other caffeic acid derivatives help modulate pro-inflammatory mediators, supporting the body's natural ability to manage inflammation during immune challenges .
