Ganoderma - Reishi
In my
correspondence with Dr. Dennis Yeo, I get the impression that the Asian people
value any specie of this genus as being excellent medicinal mushroom. Dr.
Yeo is Japanese but works for a medicinal mushroom distributor in
Singapore. He sent me a sample pack of Reishi with Goji Berries. He
told me that the package contained a newly discovered specie of G. tsugae that
grows in China. Before I started corresponding with Dr. Yeo I understood
that Reishi referred to G. lucidum, only. Here is more information from a web site:
"Ganoderma applanatum also exhibits antibacterial (including E. coli and
Staphylococcus aureus), anti-inflammatory, and anti- tumor properties and has
been used traditionally to aid the lungs and respiratory system. The Reishi
mushroom, also known by its formal name of Ganoderma and its Chinese name
Lingzhi, has attained an unparalleled reputation in the Orient as the ultimate
herbal substance. For over three thousand years it has been the most
sought-after product of nature by mountain sages and by the emperors and
empresses of all Eastern nations. In the first Chinese herbal text (Shennong’s
Pharmacopeia) written about 2400 years ago, Reishi was classified as a "superior
herb" which is defined as one that "serves to maintain life, promote radiant
health and long life because of its normalizing action, and to cause no side
effects, even when used continuously."
"The Ganodermas (Ling Chi) . . . Due to the extensive historic use of “Ling Chi”
and the ease and speed of factory production Ganoderma lucidum (Reishi, Ling Chi
or Ling Zhi) has been studied more than other Ling Chi. More study is currently
being undertaken for G. applanatum (Ancient Ling Chi), G. oregonense and G.
tsugae (Song Shan Ling Chi). Ganoderma applanatum is currently being used and
tested for tumor inhibition, immune stimulation, hemostasis, esophageal
carcinoma, rheumatic TB and as an anti-viral for HIV. "
I have found some data that implies that G.
lucidum and G. tsugae might have pretty much identical medicinal properties. In fact
all Ganoderma have good medicinal properties. Last year we had a bumper
crop of G. tsugae in the Northeast. I have yet to find my first G.
lucidum. I found several G. curtisii. This is believed to be closely
related to G. lucidum also. As I understand it, G. lucidum and G. tsugae are so similar that the only
way to identify them, without elaborate instruments, is to note on what kind of
tree they were growing. G. lucidum grows on hardwood trees, usually oak, while G. tsugae
grows on Hemlock.
Ganoderma applanatum is quite common in the Northeast. It is not as rich in medicinal properties as the others but still makes an excellent medicinal tea.
In making Ganoderma tea it is important to use very little mushroom since otherwise it becomes very bitter. There is no set recipe for making any Ganoderma Tea, just as there is no recipe for making non medicinal tea. You make simply to your own taste. The sample I got from Singapore gave instructions of using 1/4 cup of G. tsugae per quart of water. If you do not mind a bitter taste, you can make it stronger.
Here are a few potential health enhancing
properties of G. lucidum as given in the book "Mycomedicinals: An Informational
Treatise on Mushrooms" by Stamets.
-Immune enhancing
-Biological response modifier
-Stimulates macrophage production
-Activates host's production of natural killer, T cells and tumor necrosis
factors

and histamines

* The only negative side effect that I have heard from any Medicinal Mushroom is
with Reishi,
occasionally causes people to have dry mouth.
"Many strains of Reishi, thought to be Ganoderma lucidum, are actually G.
resinaceum, a nearly identical reddish species which shares in common many of
the same antimicrobial properties,"
"Although Ganoderma lucidum is the best known, many other relatives possess
medicinal properties, and are currently being studied. Of particular interest
are the conifer-degrading species, specifically Ganoderma applanatum, Ganoderma
oregonense and Ganoderma tsugae (Zhang et al, 1994; Mizuno et al., 1995)."
You would think that 13 years later there
would be more information available, but it is very hard to find. It
appears that most research is going on in Asia and Russia but the information is
not made readily available to the public. In the USA, I assume, the
pharmaceutical industry must be testing these mushrooms but they are interested
in them only if they can make a pill or concentrated medication that they can
sell for a specific ailment. It is not to their advantage to advertise
what natural medications are found in Ganoderma.
