What is Fermogulan™?

Fermogulan™ is fermented jiaogulan or Gynostemma pentaphyllum (Thunb.), a climbing perennial vine of the Cucurbitaceae family native to certain parts of South and Southeast Asia. In ancient China, jiaogulan was basically used as an energizing agent and rejuvenating elixir.

This ‘immortality herb’ has been made even more powerful than it already is through a patented and innovative Biotransforming Fermentation Technology!

Fermogulan™ contains polysaccharides, vitamins (carotene), amino acids, flavonoids and Dammarane-type saponins (gypenosides). Circa 25% of the jiaogulan gypenosides are like ginsenosides found in Panax ginseng. Guarantee of Quality: 100% natural, wildgrowing, no pesticide residues, no preservatives, no heavy metal contamination and nonGMO.

Why fermenting jiaogulan?

An innovative functional-oriented and microbial fermentation creates a biotransformation of the secondary metabolites of jiaogulan. During fermentation microbial enzymes transform poorly available herbal components into more easily absorbable healthpromoting metabolites!

What is this transformation all about?

The active components of the jiaogulan plant are essentially gypenosides, also called saponins.

The fermentation of plant extracts is still very new, and the focus is mainly on the conversion of the original glycolised saponines to the more active form. Due to their bulky molecular structures, the gypenosides are poorly membrane permeable and must therefore be further degraded.

The mass of the original gypenosides decreases after fermentation due to the removal of the sugar molecules from the gypenosides. This process is called deglycosylation. The form is the so called aglycone form, which is permeable and hence directly bioactive. Smaller molecules that are very active and well-studied, penetrate the body more easily!

Formation of new components as the rare ginsenosides

Enrichment in Compound K, Rg3 and Rh2

HPLC fingerprint analysis of rare ginsenosides in wild-growing jioagulan before (A) and after (B) fermentation. In comparison with native (unfermented) wildgrowing jiaogulan, fermented wildgrowing jiaogulan contains about:

  • 13-fold more ginsenoside CK (Compound K) ➝ anti-inflammatory effect
  • 3-fold more ginsenoside Rg3 ➝ tumor inhibition
  • 2-fold more ginsenoside Rh2 ➝ neuroprotective


Many studies show the therapeutic properties of jiaogulan. It is therefore scientifically very well founded. However, it is important that the gypenosides are available in their easily absorbable form because this is a condition for the therapeutic power of this promising plant!
