HelloPharmacist Scorecard of Fu Ling by Hawaii Pharm

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

Fu Ling is a single-ingredient supplement: poria mushroom extract (the dried sclerotia — the hard, underground fruiting body — of Poria cocos). The liquid form also contains alcohol, water, and glycerin as inactive ingredients.

Does it work?

Couldn't assess
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not assessable

This is a single-ingredient Poria Mushroom product and its label doesn't state a use — see Poria Mushroom's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The evidence for poria mushroom extract isn't established in the data we hold. The supplement has been studied for cancer, chronic fatigue, dementia, diabetes, diabetic kidney damage, and diarrhea, but all six areas show insufficient reliable evidence to rate whether it works.

That doesn't mean it's ineffective — just that robust human trials are lacking.

The evidence, ingredient by ingredient Poria Mushroom

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Poria mushroom extract is generally well tolerated in traditional use, though human safety data are limited. Rarely, allergic reactions have been reported, including allergic rhinitis (hay fever-like symptoms) and allergic asthma.

Safety during pregnancy is not well established; the available information advises against use. Similarly, there isn't enough reliable data to know if it's safe while breastfeeding, so avoidance is recommended during lactation.

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Poria Mushroom.
  • The most serious interaction on file is rated Moderate.
  • For scale: 417 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before you start, double-check this product with your pharmacist if you take CNS depressants (sedatives, sleep aids, anti-anxiety medications), anticholinergic drugs, or cholinergic drugs. Animal research suggests poria may amplify or alter how these work, though no human cases have been documented.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Fu Ling may be worth considering if you're drawn to traditional poria mushroom use, but the effectiveness evidence is thin. If you take sedatives, sleep aids, anti-anxiety drugs, or medications for muscle tone or nerve signaling, talk to your pharmacist first — the interactions are theoretical but documented.

Steer clear during pregnancy and breastfeeding.

Yes. Based on its ingredients, Fu Ling has a known interaction with 417 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Fu Ling contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.

Poria is generally well tolerated, though human safety data are limited. Allergic reactions have been reported rarely — including hay fever-like symptoms and allergic asthma. If you're allergic to mushrooms, this product may not be for you.

No. There isn't enough reliable safety data for breastfeeding, so avoidance is recommended. Check with your doctor or pharmacist about safer options.
