Poria Mushroom and Acetylcholine

Here is the interaction we found between these two, with the evidence behind it.

Moderate

CHOLINERGIC DRUGS

Why this applies to Acetylcholine

Acetylcholine falls under CHOLINERGIC DRUGS — the group Poria Mushroom interacts with.

Theoretically, poria mushroom might have additive effects when used with cholinergic drugs.
In animal research, poria mushroom essential oil reduces acetylcholinesterase activity. This interaction has not been shown in humans.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the simple version. The brand product Miochol-E is acetylcholine that an eye surgeon places directly into your eye during surgery to make the pupil get small quickly. It's a cholinergic drug, meaning it stimulates the same pathways Poria mushroom might gently nudge in the same direction. In lab and animal studies, Poria has slowed down acetylcholinesterase, the enzyme that breaks acetylcholine down. In theory, less breakdown could mean a slightly stronger or longer cholinergic effect.

In real life, this is very unlikely to be a problem. This medicine is used once, briefly, by a doctor in a controlled setting, and the interaction has only been seen in animals, not people. Still, it's smart to tell your eye surgeon about any supplements you take.

About Poria Mushroom

What is Poria Mushroom?

  • Fluid retention and swelling
  • Digestive complaints
  • Sleep and calming support
  • General wellness and immune support
  • Urinary support

Poria mushroom (Fu Ling) is a fungus long used in Traditional Chinese Medicine, mainly as a mild diuretic and digestive and calming aid. Modern scientific evidence in humans is very limited, so its benefits are not well proven. It is generally considered well tolerated, but talk with your pharmacist or doctor before using it, and avoid it in pregnancy and breastfeeding due to a lack of safety data.
