Interaction report

Poria Mushroom and Aminoglutethimide

These two interact in 2 distinct ways. Each one is explained separately below.

Why Are There 2 Interactions?

Poria Mushroom interacts with whole categories of medication. Aminoglutethimide falls into 2 of those categories, so it can interact with Poria Mushroom in 2 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Moderate).

Moderate

CNS DEPRESSANTS

1 of 2

Why this applies to Aminoglutethimide

Aminoglutethimide falls under CNS DEPRESSANTS — the group Poria Mushroom interacts with.

Theoretically, taking poria mushroom extract may enhance the therapeutic and adverse effects of sedatives.
Animal research shows that poria mushroom extract has sedative properties. 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.

Here's the simple version: aminoglutethimide (Cytadren) can already make people feel drowsy, dizzy, or mentally foggy, especially when you first start it. Poria mushroom has shown mild calming, sedative-like effects in animal studies. So the concern is that stacking the two could leave you feeling sleepier or more lightheaded than usual.

I want to be honest about how soft this evidence is. This is a theoretical interaction based on lab and animal work, and it has not been shown in actual people. It's not a dangerous combination on paper, just something to be aware of. If you notice extra drowsiness or unsteadiness, ease up and check with your pharmacist or doctor before changing anything.

ANTICHOLINERGIC DRUGS

2 of 2

Aminoglutethimide also falls under ANTICHOLINERGIC DRUGS.

Theoretically, poria mushroom might decrease the clinical effects of anticholinergic 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 idea behind this one. Lab work in animals suggests poria mushroom may lower the breakdown of acetylcholine, which is the body's "rest and digest" signal. If a medicine has any drug-blocking (anticholinergic) action, more acetylcholine around could, in theory, push back against that effect and make it a little weaker. With aminoglutethimide (Cytadren), this is really on the edges of how the drug works, since it's mainly used to lower hormone production, not as an anticholinergic.

Honestly, this is a theoretical concern only. It has never been shown in people, and food-style amounts are unlikely to matter much. Still, because aminoglutethimide is a serious medication, I'd run any poria supplement past your doctor or pharmacist first.

From our pharmacist’s overview on the Aminoglutethimide page

“Aminoglutethimide (Cytadren) suppresses adrenal hormone output, and marked drowsiness is one of its hallmark side effects, which is exactly where most of its supplement interactions strike. Of the 134 ingredients on file, 78 add their own sedation, and that group holds most of the 9 major-rated entries; alcohol is the best studied, and…”

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.
