  • Most of this tea was harvested in the village of Koporye near St. Russia, and in the 19th century it was a powerful competitor to Indian tea.
  • the leaves and tops of the fireweed stems are mainly used. Leaves of fireweed, subjected to drying and fermentation after collection, followed by drying, have a similar appearance and taste to black tea.
  • fireweed is distributed almost throughout Russia.
  • the composition of the fireweed is diverse and unique. So, the leaves of fireweed contain proteins, flavonoids (quercetin, camferol), tannins (about 20%), of which about 10% are tannins, mucous substances (up to 15%), a small amount of alkaloids (herophylline), chlorophyll, pectin.

Therefore, infusions and decoctions of the plant are recommended for diseases of the stomach and intestines, which are accompanied by increased acidity: ulcer, gastritis, pancreatitis, colitis. Tannins help to remove heavy metal ions from the body. Ascorbic acid, manganese and iron, which are part of the chemical composition of fireweed, make it possible to use the plant's infusion as an adjuvant in the treatment of iron deficiency anemia. Pectin normalizes metabolic processes, cholesterol, helps to effectively remove toxins from the body.
  • Fireweed has the highest coefficient of anti-inflammatory action among the studied plants of domestic flora.

Abstract

L'invention se rapporte au domaine de l'indutrie alimentaire, notamment à la production d'infusions, et concerne une infusion d'épilobe possédant une biodisponibilité accrue. Cette infusion de feuilles d'épilobe possédant une biodisponibilité accrue est caractérisée en ce qu'elle est obtenue par un flétrissage préalable des feuilles d'épilobe jusqu'à atteindre une humidité de 55-70%, par roulage et par traitement avec une solution de vitamine B6 selon un rapport de 75-140 mg de vitamine B6 pour 1 kg de manière première, puis par une fermentation en deux étapes et par séchage jusqu'à atteindre une humidité résiduelle de 7-12%. La première étape de fermentation se fait dans l'obscurité dans des conditions anaérobies: sous vide à une pression de 30-100 mm de Hg en colonne, ou dans un milieu saturé en azote ou en gaz carbonique, pendant 1-6 heures à une températeure de 31-50°C. La seconde étape de fermentation se fait dans des conditions aérobies à une température de 24-35°С jusqu'à la formation de notes fruitées dans l'odeur et une modification de la couleur du produit jusqu'à obtenir un vert foncé caractéristique. L'infusion finale comprend de l'acide gamma-aminobutyrique (GABA) dans une quantité de 630-1100 mg pour 100 g, de la vitamine B6 dans une quantité de 25-45 mg pour 100 g, et de l'alanine dans une quantité de 445-770 mg pour 100 g. Cette invention permet d'obtenir une infusion d'épilobe ayant une biodisponibilité accrue du fait de contenu accru en GABA, ainsi qu'en vitamine B6 et en alanine dans le produit fini.
