01What is Reishi

A settled nervous system

Reishi has been used for calm and sleep for two thousand years. The modern human trials point the same way, toward rest and resilience rather than sedation.

Calmer evenings, less racing at night
Studied for fatigue and wellbeing
Beta glucans your immune system reads
Not a sedative, no morning brain fog

Not a sedative. Nothing to sleep off in the morning.

The evidence

The science behind
Reishi

Reishi carries two families of compounds. The triterpenes, the bitter ganoderic acids, dissolve in alcohol. The beta glucans dissolve in water. This is why we dual extract, and why a single extraction leaves half of Reishi behind.

The triterpenes are the ones studied for calm and stress adaptation. The beta glucans are what your immune cells read. Together they are the reason Reishi has been valued for rest and resilience for two thousand years.

How to take it

However you take it
you will remember to

In tea

Stir through a herbal tea as the evening settles.

In warm milk

Golden milk, oat, whatever you wind down with.

Straight

One pump on the tongue before bed.

In cacao

A warm evening cacao, sweetened without sugar.

Liquid absorbs faster, lets you adjust your own dose, keeps longer, and slips into a routine you already have.

However you take it
you will remember to

The problem with pills

Most brands grow mycelium on grain, then grind the lot into a pill. The pill is mostly grain, but the label still says mushroom.

How much of it is actually mushroom

Typical powders and capsules

25% mushroom

Mycelium grown on rice or oats, then ground together

  • You are mostly buying rice
  • Half the compounds never make it out
  • A single extraction misses the triterpenes
  • You dread taking it
  • The bottle ends up at the back of a cupboard

POTENT: CALM Syrup

100% mushroom

Fruiting body only. No grain at any stage.

  • The mushroom itself, not the grain it grew on
  • Dual extracted, so the triterpenes and beta glucans both come through
  • Liquid, absorbed in minutes rather than hours
  • Sugar free, and tastes as good as wild honey
  • Becomes a ritual you actually keep
12Verified

Dual extracted

Reishi keeps its actives in two places at once. Water pulls the beta glucans, ethanol pulls the triterpenes, so both come through.

Third party lab tested

Heavy metals, microbials, and label claim accuracy. Every batch.

Our own FDA registered lab

Nothing outsourced. Extracted and filled in Chiang Mai, by us.

Dual extraction

Water pulls the beta glucans, ethanol pulls the triterpenes. The alcohol is removed.

The mushroom
of immortality.

灵芝 Língzhī

Two thousand years ago Reishi was written into the Shennong Ben Cao Jing, the oldest Chinese book of medicine. It was called lingzhi, the herb of spiritual potency, and it was so rare in the wild that for centuries only emperors were permitted it.

The Taoists painted it into scrolls and temple carvings as a symbol of long life and a settled spirit. The name carries the whole idea: not a stimulant, not a sedative, but something that returns the system to steadiness.

FAQ

How quickly will I feel the calming effects?

Some people feel more settled within an hour of the first serving. The fuller benefit, on sleep and fatigue, tends to build over one to two weeks of daily use.

Is this the same as a sleeping pill?

No. Reishi does not sedate you the way melatonin or sleeping pills do. It supports a calmer nervous system and better stress adaptation, which lets natural sleep happen, without dependency or morning grogginess.

Can I take it during the day?

Yes. Many people prefer the evening, but Reishi will not make you drowsy in the day. It simply helps your body handle stress.

Will it help with anxiety and stress?

The human trials are most consistent on fatigue and wellbeing. For stress and mood the evidence is promising but comes largely from specific patient groups, so we would frame it as support rather than treatment.

Can I take it alongside medication?

Ask your doctor first if you take blood thinners or immune suppressing medication, or if you have a liver condition. Reishi can affect clotting and the immune response, and there are rare reports of liver upset, so it is worth a quick check.

What is the difference between the syrup and capsules?

The syrup absorbs faster, lets you adjust your own dose, keeps longer, and slips into an evening routine you already have. Capsules have to be digested first.

Is this suitable for vegans?

Yes. Reishi is a fungus, and the bottle holds only mushroom extract, water and vegetable glycerin.
