Echinacea: a plant that boosts immunity

What is Echinacea?

Echinacea (Echinacea) is a perennial plant of the family of Asteraceae. She looks like a daisy. Its heart, orange, is made up of prickles, its petals are long, and depending on the variety, the flowering is white, yellow, orange, pink or red. It takes place from June to September. Its thick stem is branched. Echinacea measures between 60 cm and 1.5 m.

To grow, it likes both wet and dry areas. We can therefore see it growing in the meadows, the brush, the forests, the edges of the rivers…

Native to North America, echinacea was discovered by Native Americans. The latter used it to treat wounds, wounds, snake bites, insect bites… It was not until the 19th century that they informed eclectic doctors of its virtues.

“Echinacea has 9 varieties or species but only three species of Echinacea have medicinal properties. These are the following species: purple coneflower (echinacea purpurea) with purple petals, coneflowere pale with pink petals (echinacea pallida) and echinacea angustifolia with narrow leaves”, specifies Christine Vallée, doctor of pharmacy, founder of Herbolistique laboratories.

After the United States, and especially North America, echinacea has developed in other countries: in Africa, in Europe.

And it is only after about two years that its flowering becomes really generous.

All echinacea can be used: aerial parts (flowers), roots and leaves. Nevertheless, “we use the aerial parts, that is to say the flowers”, says the pharmacist. The flowers are harvested in the spring and sometimes until September. The roots, only in late autumn and after 3 to 4 years of growth of the plant. The roots are used exclusively dry.
