... up as #mushrooms surge in popularity. What does the evidence show?
We looked at the efficacy of #mycofermented rice vs rice placebo & data from 2 recent randomized, controlled studies. The takeaway is that #immunesupport is not about overstimulation, but balance.
Thanks to all who joined!

Hey Folks!

On Feb. 19th, I presented a the Integrative Healthcare Symposium in NYC. I am grateful to have spent time w/ an inspiring community of clinicians & #integrative #health practitioners.
In my talk on #mushroom #mycelium & enhancing immunity, we explored a question that keeps coming...

πŸ‘‹ Hi #Myconauts

We did a lot of πŸ„ foraging this year, from edible and choice species, to poisonous, and more! Thanks to all of you for coming along for the ride.

Can’t wait to see what fungi we find in 2026 !

... #Mushrooms are complex organisms, and oversimplifying them leads to poor outcomes.
These results track with 2 recent double blinded clinical studies using mushroom #mycelium fermented rice - compared to a rice placebo, post ingestion.

... The #mycelium extract supported a balanced, adaptable immune response. Under certain conditions, the fruiting body extract increased pro-inflammatory signaling.
As functional #mushrooms move into the mainstream, rigorous science, proper extraction & ingredient standardization are essential.

I adore a Clitocybe odora, the Anise #Mushroom

The smell of anise washed over & w/in us on a trail in a beautiful second conifer growth forest. It is edible but should be used sparingly because the flavor is so pronounced.

I wonder what would happen if you combined w/ fennel?

Fungal mycelium can help heal ecosystems & strengthen both food systems & our health. Mycelium supports our collective immunity.

Some call this intelligence. Others argue it’s time we expand our definitions entirely.

Fungi have long been overlooked β€” but the more we learn, the more they challenge our assumptions about consciousness, intelligence, and life itself.

🧠 Are #fungi conscious?

πŸ„ While still debated in scientific circles, researchers are beginning to uncover just how complex fungi truly are. W/out a brain or central nervous system, they navigate their environments, exchange nutrients & adapt to environmental changes.
