      Chaga. One of the most versatile and popular medicinal mushrooms. If you’re here, you’re likely thinking about incorporating chaga supplements or tea into your daily routine. But what are the potential side effects? Are there any interactions?

      There really isn’t enough evidence to state what all of the potential side effects or interactions will be. And each person is unique. That’s why it’s critical to consult your physician and pharmacist before taking chaga supplements. 

      Chaga has gained popularity as a medicinal treatment in the Western world, but many question everything from its use cases to side effects, dosing, and traditional medicine interactions.

      First, let’s cover some of the basics: 

      What is a chaga mushroom?

      Chaga (Inonotus obliquus), one of the most popular non-hallucinogenic mushrooms, has been utilized in both traditional and folk medicine across Asia, Siberia, and many Eastern European countries for centuries. 

      It can be found growing on birch tree trunks and produces a nutrient-rich growth from the wood called “conk” which resembles burnt charcoal. Roughly 10-15 inches in size, the dark black exterior of chaga may be off-putting at first glance, but has a soft, orange colored inner core and is proven to contain numerous nutrients. 

      There's much more to explore, so let’s dive in:

In particular, drinking chaga tea, which is often used to aid the digestive system and “get things moving”, has been linked to an upset stomach at times. 

      The other most common and serious chaga side effects include:

      Most of these side effects have been seen when chaga is consumed alongside specific medications. Which leads us to…

      Chaga mushroom dosing

      It is recommended to start by consuming smaller amounts of chaga at first to understand personal tolerance and reduce first time usage side effects. From there, you can adjust dosage accordingly.

      To prove chaga’s efficacy, scientists conducted an immune study on mice who were treated with an immunosuppressive alkylating agent called cyclophosphamide. It was found that, after 24 days of chaga water administration, the mice saw improvement nearly equal to immune levels seen prior to cyclophosphamide treatment.

      How do most people take chaga mushrooms?

      Today, there are dozens of ways you can enjoy chaga - but the most common ways to consume this mushroom are tinctures, extract powder, tea, or capsuled supplements.

      1. Chaga tinctures (liquid extract): Consuming either a water or alcohol-base chaga extract should have positive health benefits. Dual extraction (both water and alcohol) products are arguably the best tinctures to consume. For more dual extraction products, simply add 2 milliliters of your liquid extract (e.g., half a dropper) to coffee, tea, water, or a smoothie. Please note that serving size will vary based on product.

        2. Boil one cup of water

      1. Chaga extract (capsules): Last, but not least, and arguably the easiest way to consume chaga, is with capsuled supplements. The capsules contain the extract powder and can be taken as any daily supplement alongside water or your drink of choice.
