Medicinal Mushroom Hot Water Extract vs. Alcohol Extract
Medicinal mushrooms have been immensely popular in Asia for millennia. Today, Americans are waking up to these powerful nutraceuticals. In the wake of this new awareness follow issues of product quality claims made by competing brands.
All medicinal mushroom species are plagued by this. Most fiercely debated is red reishi (Ganoderma lucidum), the most popular of all medicinal mushrooms. So this article will primarily focus on that species, but it's generally applicable to all species of medicinal mushrooms.
First off, stay clear of cheap, mass-produced medicinal mushrooms. If they are just dried and pulverized, then the medicinal compounds are still inaccessible behind the mushrooms' cell-walls. You'll be wasting your money on inert matter.
But even among the truly effective therapeutic brands, which are plentiful, there are important differences. Each seems to claim superiority over other brands, not surprisingly, because why else would anyone buy them? This article aims to clarify the confusion of conflicting and sometimes misleading information that is out there.
Below are three common methods for extracting medicinal compounds from reishi. Each method results in different compounds. All groups have been shown to have therapeutic effects in scientific studies.
1. Water Extraction, Hot (polysaccharides and more)
2. Alcohol/Ethanol Extraction (triterpenoids, etc.)
3. Fermenting (arabinoxylanes, etc.)
Polysaccharides have been shown to possess powerful anti-tumor qualities through enhancing the immune system and by inhibiting blood profusion through tumors. They are also strong antioxidants. [1]
Through alcohol extraction, we get triterpenoids, a large group of lipids with many sub-groups. Research shows triterpenoids help regulate clotting, blood pressure and cholesterol. More importantly, they are the anti-inflammatory compounds that are the reason why reishi often gets recommended for arthritis, asthma and allergies. [1]
Finally, by fermenting the red reishi, the original medicinal compounds break down to form new compounds with unique healing properties. These "secondary metabolites" have among other things been shown to be immune enhancing and help regulate blood sugar, as well as having unique anti-tumor properties. [2]
Since this article is not intended to elevate any one brand over another, no brand names will be mentioned. Nevertheless, the author does know of two highly reputed brands (American and Japanese) that claim only hot water extracted red reishi is of any value and that alcohol extracts are useless.
Of course they do that to promote their own brand. In reality both hot water extract and alcohol extract contain unique medicinal compounds that are all very important.
When looking for the best reishi extract, find one that uses at least the first two extraction methods in combination: Hot Water and Alcohol Extraction. Even better may be a brand that includes all three methods listed.
Last but not least, remember to look at the form the reishi comes in. If the reishi is able to dissolve completely in water-based drinks like coffee, it's a safe bet that it only contains the water-soluble polysaccharides. An excellent choice as far as coffee goes but an incomplete reishi supplement because it does not include the anti-inflammatory triterpenoid compounds.
Surprisingly, though, alcohol tinctures may include both hot water extract and alcohol extract. You will know if the alcohol tincture contains polysaccharides because when the alcohol and hot water extracts are blended, the polysaccharides fall out of solution and the tincture becomes cloudy. (Just shake it before you take it.) A cloudy medicinal mushroom tincture is an indication of high polysaccharide content. Capsules and tablets may be either hot water extract or alcohol extract or both.
