The science

Nine steams,
and what they leave behind

Black ginseng is not a marketing name. It is what happens to Panax ginseng after nine cycles of steaming and drying.

The transformation

Why fermented

Your gut was going to
do this anyway

Raw ginseng carries its ginsenosides mostly as large molecules — Rb1, Rg1 and their relatives. Molecules that size are poorly absorbed in the small intestine, so the body relies on gut bacteria to cleave the sugar groups off them first and produce smaller, more absorbable forms.

That step is the catch. The conversion depends on which bacteria a person happens to carry, and studies of the relevant enzymes find the capacity varies widely between individuals — a substantial proportion convert poorly or not at all. Two people can take an identical dose and absorb very different amounts.

Fermentation begins that conversion before the stick is sealed, using controlled microbial cultures rather than whichever flora you woke up with.

Ginsenoside spotlight

What a ginsenoside
actually is

Ginsenosides are the saponins found in Panax ginseng — and essentially only there. They are the reason the plant has been studied for centuries rather than eaten for nutrition; the root is otherwise unremarkable.

More than a hundred have been identified. They are not interchangeable: they differ in molecular size, in how readily the body absorbs them, and in which effects the research associates with them. A label that gives you a total milligram weight and no ginsenoside figure is telling you about plant matter, not about the compounds.

They are also what you are tasting. Saponins are bitter — that is the same class of compound doing both jobs, which is why a ginseng that tastes of nothing is usually a ginseng that contains very little.

A class of plant compound named for its soap-like foaming in water. Ginsenosides are the saponins specific to Panax ginseng.

What changes

The compounds that matter

  • Rg3 — the rare ginsenoside

    11.8 mg

    Nearly absent in raw ginseng — it's created by repeated steaming. The compound most associated with stress resilience in the literature. Its two forms, S and R, counted together.

  • Rb1 — the classic

    3.8 mg

    The best-studied ginsenoside of fresh ginseng. Its usual partner, Rg1, measured just 0.03 mg: steaming turns it into other forms, such as Rh1 and Rg2.

Measured in our extract sticks made on 21 August 2026, in mg per 10 g. The full ginsenoside report is below.

Taste

Why bitter is
good for you

Bitterness is not a flaw in the process, it is the ginsenosides announcing themselves. The saponins responsible for the taste are the same compounds the extract is measured on, so the intensity tracks the concentration rather than fighting it.

Bitter compounds are also detected well beyond the tongue — bitter taste receptors have been identified throughout the digestive tract, and a bitter stimulus is associated with digestive responses that begin before anything is absorbed. It is a signal your body is built to read.

Which is why nothing has been added to mask it. No honey, no sweetener — 30% concentrate, 70% purified water. It passes in well under a minute, and most people stop noticing by the end of the first week.
