Purple coneflower (Echinacea purpurea)

Author: dr. Borut Gosar, PhD in Biotechnology · Updated May 29, 2026

Purple coneflower (Echinacea purpurea L.) is one of the most well-known medicinal plants. However, its quality largely depends on how it is cultivated and processed – which was the central focus of the doctoral research conducted by the founder of the Dr. Gosar company.

First-hand Expertise

The founder of the company, dr. Borut Gosar, was employed as a young researcher between 2005 and 2010 at the Biotechnical Faculty in Ljubljana, where he worked in the field of medicinal plant biotechnology – including active ingredient analysis (HPLC), in vitro immunological tests, and statistical data processing. In 2010, he successfully defended his doctoral dissertation titled "The impact of technological factors on the quality and cultivation possibilities of purple coneflower (Echinacea purpurea L.)". This makes him the only person in Slovenia to hold a PhD specifically focusing on this plant.

Why Cultivation is Key to Quality

The content of active substances in Echinacea is not constant – it is influenced by the choice of plant part, the timing and method of harvesting, drying, and the processing method. It is precisely these "technological factors" that were addressed in the doctoral research. Consequently, two seemingly identical Echinacea products can differ significantly in their composition. At Dr. Gosar, we manage the entire process ourselves – from cultivation to extraction.

Our Approach to Processing

  • In-house cultivation and processing – control over the entire chain, from the field to the product.
  • Concentrated extract instead of diluted preparations.
  • Alcohol-free and preservative-free honey-based products – suitable also for children.
  • Knowledge backed by scientific work and analytics (HPLC).

Echinacea with Honey

In addition to the concentrated extract, we also offer Echinacea combined with honey. Honey serves as an excellent carrier, and the product contains no alcohol or preservatives, while maintaining a pleasant taste.

Our Echinacea Products

All products: Echinacea category.

Frequently Asked Questions

What makes Dr. Gosar Echinacea different?

The source of knowledge and quality control: the products are developed by a Doctor of Science who earned his PhD specifically in the cultivation of this medicinal plant, and the entire process takes place within our own cultivation and processing facilities.

Is it suitable for children?

Our honey-based products do not contain alcohol or preservatives. For use and dosage in children, please follow the instructions on the packaging, and consult a doctor or pharmacist if you have any questions.

How should the product be stored?

In a cool and dark place, out of reach of children; please refer to the instructions on the packaging.
