Our Focus on Chaga

"When I was a young man, the knowledge of healing fungi was introduced to me by my grandmother. After mowing her lawn, I drank a glass of what I thought was iced tea from her refrigerator. She gleefully informed me that I was drinking a fungus! I followed her to a birch tree in her backyard where she demonstrated how to harvest chaga, taught me about its benefits and how to transform it into tea. It wasn’t long before I had developed a deep passion for chaga and started harvesting it for my grandmother. Chaga took over my life, and my brainchild, Birch Boys, was born. My mission is to spread awareness of wild healing fungi and encourage people to live symbiotically with our natural allies."

Chaga Tincture

High quality product from a conscientious company

Wonderful product!

I have been adding this tincture every day to my tea or coffee for the past month. I was a bit of a sceptic at first, but I have increased energy after taking it. I have increased the intensity of my workout routine because of this! I haven't had a cold or even though I have been exposed to others who have been ill. I am definitely a big fan of this tincture!

Helps with everything

I first tried chaga when I heard it could help with my eczema, did a lil research online for the best and keep hearing birch boys come up so I gave their tincture a shot, just finished my 3rd bottle and can happily report that most of my eczema has cleared up or is healing with the exception of some stubborn spots. Its also helped me considerably with allergies and some gut issues I have been having. Overall an excellent product and after watching Garrett’s youtube video’s will be a longtime customer, guy really knows his stuff.

Starting a Chaga Routine


Embark on a transformative journey to wellness with our guidance on starting a Chaga routine. We provide valuable insights, practical tips, and reliable information to help seamlessly integrate Chaga into your daily life. Empower yourself with the knowledge needed to kickstart a Chaga routine aligned with your health and wellness goals.


How To Get Started

For a good starting point, find the situation that describes you best and click to read on.

If you’re a total newbie to fungi, WELCOME!

For those who are new to fungi, we recommend starting low and going slow. This is because any time you introduce a new type of micronutrient into your diet, it is good to give your gut a short period of time to adjust.

Start with a serving size of 1mL for a week (similar to CBD, it's always good to start low and go slow). If your gut is behaving normally after one week, you can move onto the next step!

Now, you can work on figuring out which serving size is right for you. If you find that you’re not experiencing the desired effect from the tinctures, you can increase your serving size by 1mL, as needed (up to 4mL.)

Once you've figured out your sweet spot, you're all set!

For more info, move onto the next section.

If you are already taking a mushroom supplement, drinking a mushroom tea, or regularly consuming mushrooms, then your gut is likely already used to mushroom micronutrients. You can start at any serving size (up to 4mL) but we recommend starting with a 1- 2mL serving size and increasing as needed (up to 4mL.)

If you are targeting a specific issue, and you’re new to fungi, start with 1mL per day for one week. After that, if your gut is behaving normally, then you can increase your serving size to the full 4mL per day.

If you're targeting a specific issue and you regularly consume mushrooms or mushroom supplements, feel free to start at whatever serving size you're comfortable with (up to 4mL.)

If you are working with an herbalist or medical provider who works with natural remedies, consult with them to determine your recommended serving size.

How to Maintain Your Chaga Routine

Now that you know how to get started, let's talk if, why and how you should make a change in your routine. Here are some reasons people may change their tincture routine and the accompanying solutions. Click the tabs to read more.

If you have been using the tinctures for 1-2 months and are not experiencing the desired results, you may need to increase your serving size. We recommend increasing your daily serving by 1mL per week, up to 4mL.

If you have already increased your serving size and you are not noticing any benefits, you may be someone who is more resistant to the noticeable benefits of the tinctures. That doesn’t mean that you aren’t getting any benefits! Some people notice gradual change less than others do, and that’s okay.

Occasionally customers will stop using tinctures for a short time and in doing so, they realize that the tinctures were working for them! This is because they did not notice the gradually appearing benefits, but they did notice the absence of those benefits when they took a break.

Each person is unique, so in some cases, a customer may find that one (or several) tinctures have a profound effect on their life, but a different tincture may not affect them as profoundly. In this case, just continue using the tinctures that work best for you! That's what our Custom Mushroom Tincture Bundle is for!

Our Chaga, Lion’s Mane, Turkey Tail and Maitake are all energy-providing, stimulating tinctures. If you’re feeling overly energetic or overstimulated, decrease your serving size by 1mL per week until you find your sweet spot. We also recommend taking the aforementioned tinctures in the morning or afternoon, rather than in the evening, since they are so stimulating.

Our Reishi Tincture is a calming tincture. When Reishi Tincture is taken during the day, most people experience a more calm and collected mood, rather than feeling drowsy, but that’s not always the case. If you find that taking the Reishi Tincture in the morning makes you drowsy during the day, we recommend taking it in the evening instead of the morning.

Alternatively, if you like taking Reishi in the morning but want to feel less calm/drowsy during the day, you could decrease your serving size of the Reishi Tincture or add one of our energy-providing tinctures to your routine. Chaga and Lion’s Mane work very well for energy.

This is an incredibly rare instance.

If you are experiencing unwanted effects from Mushroom Tinctures, stop taking the tincture(s) and reach out to us for more information. We are not medical professionals and cannot dispense medical advice, but we will work with you to make the situation right.

If you are on certain medications, are pregnant and/or breastfeeding, or if you have an upcoming surgery, we recommend speaking with your medical provider before taking Mushroom Tinctures.
