In This Article, You Will Learn:

And now, let’s jump in!

Side Effects Of Chaga

Although Chaga consumption does not commonly produce adverse side effects, there are still some precautions you should know. If you are frail or take other medications, you should talk with your doctor. Chaga is generally safe.

However, you should know about all potential side effects:

Bruising & Bleeding

The main side effects associated with Chaga mushroom are with its possible interactions with other drugs. For example, the extract may affect drugs that thin the blood and reduce coagulation (aspirin and warfarin for example). Chaga contains minerals, proteins, polysaccharides and many more antiaggregant substances that can have a synergistic effect. You need to be careful when adding drugs together, and in this case, you may need to be aware of too much blood thinning.

Surgery

Chaga may reduce blood clotting, which again can affect bleeding during and after surgery. It’s better to stop using Chaga at least 2 weeks before a scheduled surgery

Diabetes (Hypoglycemia)

When your blood-sugar level drops too low (Hypoglycemia) you may feel weak, shaky, hungry, thirsty, confused, irritable or you may have difficulty speaking. Diabetes is a serious illness and can be treated under a doctors care with injected insulin, which moderates blood sugar levels.

There are cases where Chaga mushroom supplements may interact negatively with insulin and other medications.

Pregnancy & Breast-Feeding

There have not been enough scientific studies about the use of Chaga during pregnancy and breast-feeding. Therefore it’s better to stay on the safe side and avoid use.

Auto-Immune Diseases

Chaga can affect auto-immune diseases like multiple sclerosis (MS), rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE) by making the immune-system more active. Chaga can boost the immune system, which is exactly what you don’t want when your own immune system is attacking you. If you have one of these conditions, please be on the safe side and avoid Chaga.

Those were the main Chaga mushroom warnings you should know about.

Chaga Side Effects Compared With The Reishi Mushroom

Reishi Mushroom compared with chaga mushroom

We’ve found a very interesting book about the side effects of mixing herbs. It is titled “The Essential Herb-Drug-Vitamin Interaction Guide,” by George T. Grossberg and Barry Fox.

Well, though Chaga mushroom side effects aren’t well researched (or known). We can look at the side effects of another distantly related mushroom, the Reishi mushroom, and compare these theoretical side effects with possible side effects in Chaga. The side effects of the Reishi mushroom can be dry mouth and throat, nosebleeds, itchiness, an upset stomach and bloody stools.

Chaga is quite safe on side effects. However, if you have a condition we talked about in this article, you should be aware. If you are looking for side effects by yourself, keep in mind that Chaga, like many other mushrooms, is rich in beta glucans. These have immunomodulating activities and are of interest because they bind to complement receptor 3 (CR3). This allows immune cells in your body to recognize cancer cells and theoretically specifically target them for death without harming the healthy cells.

Myth: Chaga Gives Narcotic Effect

Psychedelic drugs have captivated people since humans first experimented with special herbs and mushroom. The mind can take you places that your body can’t allow. That’s why some people use substances to change their brain and bodies in order to feel, hear and see something wild or new.

Mushrooms are a very popular way to achieve those psychedelic “trips”, and certain mushrooms can take you there. We must disappoint you, because Chaga doesn’t have any narcotic effect whatsoever. We mean, no matter how you consume it, it doesn’t contain psychotropic or narcotic ingredients. It will not take you on a “trip” as some drugs and mushrooms can. We often get this question from folks who are looking for new (and legal) ways to get high. Chaga won’t do it.

Low-Quality Chaga Can Have Negative Side Effects

Low Quality Chaga One thing you should keep in mind is where you buy your Chaga. You might ask, “why?” As we wrote on the Chaga buying guide, there are shady Chaga suppliers who don’t offer pure Chaga. They pay only by weight, which can be manipulated, and they use pickers who just do it for money.

They may mix it with sand or dirt, or keep it in (stagnant) water to increase weight for more money. Bacteria can then grow in this foul soup they make for money. There are lab tests from Chaga wholesale buyers that have proven this kind of conduct.

One nasty way is to mix it with other similar looking mushrooms. This not only dilutes the Chaga but can give you really bad side effects, depending on the other mushroom.

Considerations

We have stated the known Chaga mushroom side effects here. However, there might be more that aren’t documented yet. Chaga is a safe supplement. However, you should always listen to your body and consult your doctor.

Like with everything in life, whatever you do, you should do it responsibly. Going from zero to 20 cups of Chaga mushroom tea can give you produce side effects because your body isn’t used to it. But with responsible moderation, there will be no Chaga tea side effects.

The product is most simple. It is a natural product with nothing added, so it is important to make sure you have quality Chaga. To ensure the quality, you should also harvest it.

Reader’s Side Effects

Staicia, 51, Maine

I received some free chaga from a family friend. Anyway, I read online about how to dry and prepare it. I chose to boil in for a few hours and have been drinking 6 oz. of tea every day for about 8 weeks. After having a head cold over the holidays I wanted to stay healthy. I started the chaga when I recovered from the head cold. I live a healthy life style, don’t smoke, and get plenty of exercise.
About 1 month ago I started to get sick (sore throat, cough). I thought it was strange since I was just sick over Christmas. After 2 weeks went by and I didn’t feel better I went to the doctor who said to keep drinking plenty of fluids and wait another week and if I didn’t feel better to come back in. I didn’t mention the Chaga to him but it was in the back of my mind.
My cough was getting worse and I was having a hard time breathing like I might have the flu. But I didn’t have any other flu symptoms like a fever, body aches, intestinal abnormalities, or head ache and the sore throat was gone after the first week. Today is Tuesday, and 3 days ago I stopped drinking chaga and I’m completely well now. I started to noticed a difference the day after I stopped drinking it.

Louise, Sweden

We have picked our own chaga in Sweden and have been drinking it every day for one year.
Lately my husband and I have had some cartilage problems (feet and hand)
Interested if you have had some others chaga consumers with the same issues.
