Medicinal mushrooms, hugely popular for thousands of years in the Orient, are coming in vogue today also in the West. On the coattails of their increasing popularity follow issues of quality and ethical representation between competing brands.
All species of medicinal mushrooms appear haunted by this issue. Particularly so, it seems, is red reishi (Ganoderma lucidum), the oldest medicinal mushroom in Traditional Chinese Medicine. Please note, however, that the information in this article applies generally to all medicinal mushroom species.
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.
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 (Hot) Extraction (polysaccharides, etc.)
2. Alcohol/Ethanol Extraction (triterpenoids, etc.)
3. Fermented (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]
Triterpenoids include a large number of related medicinal compounds whose proven effects include stabilization of blood pressure, cholesterol, and blood clotting. But most importantly, the triterpenoids are the anti-inflammatory compounds of reishi. [1] Inflammation is a serious component in asthma, allergies, arthritis and many more conditions.
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]
This article is not meant to recommend any particular brand so none will be mentioned by name. But the author does know of two reishi companies (Japanese and American) that both claim only hot water extract of reishi is effective and that alcohol extracts are of no use.
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.
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.
On the other hand, alcohol tinctures can actually contain both water soluble polysaccharides and alcohol soluble triterpenoids. The way you know is that the polysaccharides will fall out of solution because of the alcohol, and will make the tincture cloudy. That's alright though; you just need to shake before you take. Capsules and tablets may be one or the other or both. The only way to know is ask the manufacturer or read their information.
