Humans have been fascinated by Mushrooms for millennia. We have used them in traditional medicine for at least 2000 years and probably much longer.
Medicinal Mushrooms contain a complex array of beneficial compounds. These compounds through their complexity can support our immune system, act as adaptogens, and help balance the function of essential systems in our bodies.*
In this introduction, we will focus on the water-soluble components of medicinal mushrooms, Polysaccharides and beta glucans. If you're not familiar with these, don't be intimidated by the names. I'm going to break down a clear and concise explanation of each.
The term polysaccharide simply means "many sugars." A polysaccharide is a number of sugar molecules linked together to make a structural fiber. The most common polysaccharide in nature is cellulose (the building block of plants) which takes the form of a long linear chain. The second most common is chitin the building block of mushrooms.
Medicinal mushrooms can contain several types of polysaccharides, some of which are very complex. Polysaccharides called beta-glucans are present in many mushrooms. These are made of a single type of sugar (glucose) and can have multiple branches giving them complex shapes. There are also, heteropolysaccharides which are made of multiple types of sugars and protein-bound polysaccharides, which as the name implies are polysaccharides molecularly bound to protein.
Most of the medicinally valuable mushroom polysaccharides are locked up by chitin in cell walls. Since our digestive system doesn't effectively break down chitin, the polysaccharides need to be extracted from the mushrooms to gain their medicinal benefit. This is accomplished via a hot water extract which you can learn more about on our process page.
As polysaccharides travel into our digestive system, they attach to receptors on our immune cells (Macrophages and Dendritic cells). There are many of these cells on the surface of our digestive system as one line of our immune defense. Some polysaccharides may also be absorbed by our gut into our bloodstream and attach to immune cells there.
Once attached to an immune cell receptor the polysaccharide creates a response in the immune cell. This response is communicated to the rest of our immune system via a chemical signal (Cytokines). This response will vary depending on the type of immune cell/receptor and the size/type of polysaccharide. The response may take the form of immune boosting as signals can be sent out to increase the activity of immune cells. The chemical signal may also produce an immune moderating or adaptogenic response.
A lot of people ask what adaptogens do. The simple explanation is that they help balance and regulate a system (or systems) in your body.
Picture this, a third-grade classroom filled with 30 chaotic 9-year-olds left to their own devices before the school bell rings. Sometimes systems in our body act like that. At the school, a good teacher walking into the classroom restores calm and order for the kids. In our bodies, adaptogens promote that state of balance and calm for our systems.
