What are the characteristics of Echinacea?

Native Americans (South Dakota) used this plant to heal infected wounds, and as a local application for snake bites. To use it, they crushed the fresh plant and applied it locally, or chewed the root. The name Echinacea derives from the Greek echinos, meaning "hedgehog", and refers to the spiky flower head. Purpurea is Latin for purple, a purplish-red color.Echinacea was one of the main medicinal plants of the indigenous peoples of North America, particularly the Cheyenne, Oglala Lakota, Kiowa, Crow, Omaha, Pawnee, Poncas, Teton, Delawares and Comanche. They used the juice or porridge from the crushed herb or chewed pieces of root. Decoctions were rarer.

It is assumed that the natives did not differentiate between the various types of Echinacea, but used the kind that grew in the region where they lived. The white settlers of North America adopted echinacea as a native remedy. As early as 1737, a description of the plant and its medicinal properties can be found in John Clayton's "Catalogue of Plants, Fruits, and Trees Native to Virginia". Known as "Black Sampson", echinacea was later mainly used as a universal remedy in folk medicine. In 1852, E. purpurea was cited for the first time in the "Ecclectic Dispensatory of the United States", praising its effectiveness against syphilis. Around 1869, H.C.F. Meyer produced and sold in Pawnee City the first pharmaceutical speciality under the name of "Meyer blood depurative".

Echinacea's popularity grew, as did the number of glowing reports about it. However, in 1909, echinacea was not recognized as effective enough to be included in the list of "New and Non-Official Remedies". In 1911, the first complete pharmacognostic study of E. angustifolia was published, with numerous microscopic illustrations. By the 1930s, echinacea was gradually losing interest in the USA, and fewer and fewer articles were published. In Europe, interest in echinacea only began in 1897. Clarke described its clinical success in detail in his "Dictionary of Practical Materia Medica", published in London in 1900.

A homeopathic pharmacological survey was published in 1906, and in 1924, E. angustifolia appeared in Dr. Wilmar Schwabe's "Homöopatisches Arzneibuch" (homeopathic pharmacopoeia). Stauffer and Madaus were pioneers in the use of echinacea in Europe. Since then, the various types of Echinacea have been extensively studied from morphological, pharmacological and clinical points of view. The most comprehensive documentation concerns E. purpurea. A. Vogel discovered Echinacea purpurea in the early 1950s during a cross-country trip that took him to South Dakota, among other places. He befriended Black Elk, the chief of the Oglala Lakota, who introduced him to the healing arts of his tribe and gave him a gift of echinacea seeds. The resulting plants formed the basis of his own experiments with echinacea, which became an essential plant for Alfred Vogel.

Echinacea is a plant with multiple benefits, particularly recognized for its action against winter ailments. Not only does it reduce cold symptoms such as nasal congestion, coughing and sneezing, it also helps to shorten the duration of the infection.

Thanks to its immunostimulant properties, echinacea naturally boosts the immune system, helping the body to better defend itself against seasonal viruses. It is also useful for relieving persistent sore throats and soothing irritations. In addition, this medicinal plant is effective for soothing localized infections in the ENT sphere (nose, throat, ears), offering natural support in cases of sinusitis, pharyngitis or the onset of angina.

  • Latin name: Echinacea purpurea (L.)
  • Botanical family: Asteraceae
  • Producer organ: Root (or whole plant with root)

How to dose echinacea according to its galenic form?

  • Fluid extract 1 gram or 50 drops per day in a single dose
  • Mother tincture 50 drops twice a day
  • EPS 5 ml per day
    • For prevention, always in discontinuous courses of treatment, 10 to 15 days a month

Acutely:

  • Echinacea purpurea juice 2 to 3 ml or 1 to 2 ml extract, 1 to 4 times a day, either mixed with water or taken sublingually.
  • Echinacea purpureadry extract (concentration ratio 6.5:1) 3 times daily 150 to 300 mg
  • Alcoholic tincture (1:5, ethanol 45%), 1 to 5 ml 3 times a day

How does echinacea affect the immune system?

  • Echinacea is thought to be adreno-mimetic
  • Complex immunomodulatory activity, stimulating the phagocytic activity of macrophages and suppressing the pro-inflammatory responses of epithelial cells to viruses and bacteria, leading to altered secretion of various cytokines and chemokines.
  • Immunostimulant activity is due in particular to polysaccharides, but the lipophilic fraction(alkylamides) is also active, particularly on macrophages.
  • Alkylamides inhibit the production of prostaglandin E2 (PGE(2)) by macrophages, contributing to the immunostimulant and anti-inflammatory effect.
  • Alcoholic root extracts enhance granulocyte phagocytosis
  • Polyacetylenic derivatives are chemotaxonomic characteristics of the Asteraceae family .

What precautions should I take before using Echinacea?

  • Contraindications: autoimmune diseases and progressive illnesses such as tuberculosis, leukemia, collagenosis, MS, AIDS.
  • Contraindicated in pregnant or breast-feeding women, and in children under 12 years of age.
  • Avoid the following combinations:
    • Steroids (additive immunomodulatory properties)
    • Immunosuppressants (theoretical alteration of immunosuppressive effect)
  • Possible interaction with CYP450 enzymes (isoenzyme inhibition, increased drug effect, but no clinical evidence in vivo)
    • No interaction noted with cytochrome CYP2D6
    • Inhibition of cytochrome P450 isoforms 3A4, 1A2, 2C19, 2D9(alkylamides)
  • Leukopenia reported with prolonged use

What are the active ingredients in Echinacea?

  • Alkylamides or alkamides (unsaturated aliphatic compounds: 2%, some 15 compounds have been identified) in the lipophilic fraction, including echinacein; these are polyines or isobutylamides of polyenynic and polyenic acids (= polyacetylenes).
  • Phenolic compounds derived from caffeic acid, such as echinacoside (0.3 - 1.3%), cynarin or cichoric acid, specific to one or other species.
  • Cichoric acid and caftaric acid
  • Complex polysaccharides with M > 10000 D, including arabinogalactan, arabinorhamnogalactan, fucogalactoxyloglucan, glucuronoarabinoxylan
  • Indolizidine alkaloids
  • Long-chain fatty acids, alkanes
  • Essential oil with humulene (= alpha-caryophyllene) and echinolone

The flowering and underground parts of Echinacea purpurea are on List A of the French Pharmacopoeia.
