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.
An obvious caution is to stay away from cheap, mass-produced reishi. It may be merely dried and pulverized. In order to be medicinal, the mushroom cell-wall has to be broken down. Mass-produced reishi may be mostly inert and ineffective.
There are many real therapeutic brands on the market, though. But even among them, there are significant differences. They all claim to be the best, naturally, because they all want to sell their particular brand. So let's sift the data, get the facts straight, and clear up misleading information that is out there.
Following are the three primary ways of creating reishi extracts. Each method yields different medicinal compounds, all of which are shown in scientific studies to have important properties.
1. Water Extraction, Hot (polysaccharides and more)
2. Alcohol Extraction (triterpenoids, sterols)
3. Fermented (arabinoxylanes, etc.)
The most important hot water extracted compounds are the polysaccharides. Studies have shown them to possess strong anti-tumor properties, help boost immune system and be powerful 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]
And then there are the new and unique medicinal compounds that get created when reishi is fermented. These "secondary metabolites" have their own therapeutic properties, different from the first two groups, including anti-tumor, immune support and blood-sugar balance. [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.
Naturally, the reason they say so is because they want to sell their own brand. However, those statements are scientifically untrue. Hot water and alcohol extractions both contain critical compounds.
To determine if a brand of reishi (or Ganoderma) contains all the important medicinal compounds from the mushroom, find out if it utilizes both alcohol and hot water extraction. An additional plus would be if it also includes fermented reishi.
An additional point to keep in mind is the form the reishi comes in. Reishi that dissolves completely in a water-based liquid such as coffee probably only contains reishi from hot water extraction. As a substitute for regular coffee, this would be a superb health-choice. However, it will not contain the water-insoluble triterpenoids so valued for their anti-inflammatory properties.
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.
