Reishi Reviews
From customers who've made wild reishi part of their routine.
"Dad Approved. I take Reishi every night, but the idea of Artist Conk helping me restore balance during the day sounded lovely. We just had our second baby and this tincture has helped me keep my balance and calm during the after a night of poor sleep. Life is extremely hectic right now and this is helping me remain calm and locked in. 10/10. Just ordered another 8oz bottle."
"I'm so happy I ordered Organic Reishi Tincture from Birch Boys. I am noticeably calmer and my digestive system feels better than ever. I also seem to have more clarity of thought. I'd recommend it to anyone."
"Love it and always make sure I have this one on hand! The Reishi Rosehip tea is an evening ritual for me, with the subtle and beautiful flavor that relaxes my mind and body anytime I need it. For me it's the perfect blend right before bed."

Frequently asked questions
Reishi contains beta-glucans and ganoderic acids, two compound classes studied for their effects on immune function, stress response, and sleep quality. It's been used in traditional herbalism for centuries and remains one of the most researched functional mushrooms available. Birch Boys wild-harvests reishi from the Adirondack forests, where it grows on hemlock trees in old-growth stands.
Reishi builds over time. Most people notice effects after 2–4 weeks of consistent daily use. If you're taking it primarily for sleep support, you may feel a calming effect sooner. Give it a month of daily use before drawing conclusions. Check out our mushroom tincture guide for more info.
Reishi is well-tolerated by most people and has been used safely for centuries. If you're pregnant, nursing, on blood thinners, or managing a health condition, check with your doctor before adding reishi to your routine.
For reishi tea, 1–3 cups per day. For reishi tincture, 1–2 servings daily, which delivers 417–834mg of reishi extract. Either way, consistency matters more than volume — daily use over time is what moves the needle with reishi.
No. Reishi contains no psilocybin or other hallucinogenic compounds. It's a polypore fungus, not a "magic mushroom" in any sense. The effects people describe are subtle and cumulative: calmer, more restful sleep, steadier energy over time.
Clinical research on reishi use during pregnancy and breastfeeding is limited.
Out of caution, we recommend consulting your medical provider before adding reishi to your routine while pregnant or nursing.
Take 1 to 4 ml daily, either directly or added to coffee, tea, or any beverage at a comfortable drinking temperature. If you're new to mushroom extracts, start at 2 mL and increase as comfortable. For a full walkthrough on building a tincture routine, visit our mushroom extract guide.
Reishi is an adaptogen, a category of substances studied for supporting the body's normal stress response. While specific research on reishi and cortisol is limited, it is a great overall stress management tool. Consistent daily use over several weeks tends to produce more noticeable results than sporadic use.
