Korean Reishi Mushroom Slices | Dried Lingzhi for Tea | 2.2 oz

Kosbee Korean Reishi Mushroom Slices are pre-cut, dried reishi — lingzhi (영지, Ganoderma) — grown in Korea, with no additives, sliced to an even thickness so the hard mushroom is ready to simmer straight into a deep, earthy tea or broth.

Reishi is woody and deeply earthy, with a strong natural bitterness that comes from its triterpenes. A little honey or jujube softens it beautifully. Each resealable pouch holds 2.2 oz (62 g).

For centuries, reishi — lingzhi — was treasured across East Asia as one of the most prized mushrooms, simmered slowly into a deep, dark, earthy tea. Kosbee selects Korean-grown reishi, harvested at its peak and cleanly sliced, so you can brew that same time-honored cup at home.

Korean-Grown, Pre-Sliced, Ready to Brew

Whole reishi is famously hard to cut at home, and cheaper imports can be uneven and hard to trust. Kosbee reishi is grown in Korea, where pesticide and heavy-metal standards are strict, and comes cleaned and pre-sliced.

It is a Product of Korea with a clear origin — no sawing through a tough cap, and no guessing about sourcing.

What's in the Pouch

100% Korean Reishi Mushroom (Lingzhi / 영지, Ganoderma)

Pure dried reishi grown in Korea, with no additives — just sliced mushroom.

Pre-Sliced, Ready to Use

The hard mushroom is cut to an even thickness, so there's no sawing through a tough whole cap.

Deep, Earthy, Boldly Bitter

A woody, earthy mushroom with a strong natural bitterness — best softened with honey or jujube.

Caffeine-Free, Clean Label

0 g added sugar, no caffeine, dyes, or preservatives — just the dried slices.

Each 2.2 oz (62 g) pouch is enough for many pots; for tea, most people use 3 to 5 slices (about 3 to 5 g) per batch.

How to Brew Korean Reishi Mushroom

For tea, add 3 to 5 slices (about 3 to 5 g) to 1 quart (about 1 liter) of water, bring to a boil, then simmer on low for 30 to 60 minutes and strain.

Reishi is boldly bitter, so stir in honey or simmer it with jujube to round the cup into something smoother and naturally sweeter.

For a broth, add 1 to 2 slices to samgyetang or other soups for a deep, earthy, woodsy background note.

How to Enjoy It Safely

Reishi is naturally very bitter — that bold taste comes from its triterpenes and is normal, not a sign of a flaw — so soften it with honey or jujube as above.

If you take prescription medication, such as blood thinners or blood-pressure medicine, or are pregnant or nursing, talk to your doctor before using it.

If you have a mushroom allergy, check the label before trying it, and enjoy it in moderation.
