HelloPharmacist Scorecard of Earth Dragon by Allergy Research Group
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
Low disclosure
Earth Dragon has four active ingredients. Earthworm extract, poria mushroom extract, calamus (Grass-Leaf Sweetflag root extract), and atractylodes (Bai-Zhu root extract) are combined in a proprietary blend.
The product also contains inactive ingredients — hydroxypropyl methylcellulose, microcrystalline cellulose, cellulose, and L-leucine — which serve as capsule material, binder, and flow agent.
Does it work?
Couldn't assess
The evidence for Earth Dragon's ingredients is not established in the data we hold. All the conditions listed for poria, calamus, and atractylodes — including cancer, chronic fatigue, dementia, diabetes, asthma, anorexia, and common cold — carry a rating of insufficient reliable evidence.
We have no effectiveness data on file for earthworm extract.
How safe is it?
Well-documented data
Poria mushroom extract is generally well tolerated in traditional use, but human safety data are limited. Rare allergic reactions, including allergic rhinitis and asthma, have been reported.
Calamus carries a significant safety concern: some forms contain beta-asarone, a possible carcinogen banned from food by the FDA, and calamus may cause cancer. Nausea, vomiting, and in rare cases intestinal paralysis and rapid heartbeat have been reported.
Atractylodes has limited human safety data; common side effects are allergic reaction, dry mouth, and nausea. We have no pregnancy or breastfeeding safety data on file for atractylodes.
Meds to double-check
Moderate interaction found
Before taking Earth Dragon, double-check if you're on sedatives or sleep aids (CNS depressants), blood pressure medications (antihypertensive drugs), blood thinners or antiplatelet drugs, drugs broken down by your liver via CYP3A4 or CYP2D6 pathways, anticholinergic drugs, cholinergic drugs, or MAOIs (antidepressants). Also check if you take heartburn medications (H2-blockers).
The bottom line
Scorecard at a glanceFormula with limited ingredient disclosure with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
This product carries documented medication interaction risks, particularly with sedatives, blood pressure drugs, blood thinners, and drugs processed through the liver. Calamus specifically has safety concerns related to potential cancer risk from beta-asarone.
The effectiveness of any ingredient is not established in our data. Talk to your pharmacist before taking Earth Dragon, especially if you're on any prescription medications or planning to use it during pregnancy or while breastfeeding.

Earth Dragon by Allergy Research Group Drug Interactions
HelloPharmacist Interaction Report
Earth Dragon by Allergy Research Group contains four ingredients, two of which we could not fully assess for interactions.
The product does carry documented interaction risks. The most serious concern involves calamus (Grass-Leaf Sweetflag root extract), which can theoretically slow the breakdown of drugs processed through your liver's CYP3A4 pathway — a very common route for many medications — potentially raising their levels and side effects.
This is a Moderate severity interaction.
Read the full breakdown — every affected drug type, severity by severity
Calamus also interacts with sedatives (CNS depressants), blood pressure medications, drugs broken down by CYP2D6, anticholinergic drugs, cholinergic drugs, and MAOIs — all rated Moderate. It may also reduce the effectiveness of heartburn medications (H2-blockers), rated Minor.
Poria mushroom extract can theoretically enhance sedatives and has additive effects with cholinergic drugs or may reduce the effectiveness of anticholinergic drugs — all Moderate. Atractylodes (Bai-Zhu) can theoretically increase bleeding risk with blood thinners and antiplatelet drugs, prolong the effects of the anesthetic hexobarbital, and affect CYP3A4 and CYP1A2 substrates — Moderate and Minor severity.
We could not check earthworm extract; no data on file for it. Altogether, these interactions span 1,203 individual medications.

Grass-Leaf Sweetflag (root) extract
Anticholinergic Drugs
Theoretically, concurrent use of anticholinergic drugs and calamus might decrease the effectiveness of the anticholinergic drug.
In vitro evidence shows that calamus can inhibit acetylcholinesterase (AChE).
Antihypertensive Drugs
Theoretically, taking calamus with other antihypertensive medications might increase the risk of hypotension.
Animal research shows that calamus decreases the rate and strength of the heartbeat, which might lower blood pressure. use with caution.
Cholinergic Drugs
Theoretically, concurrent use of cholinergic drugs and calamus might have an additive effect and increase the risk of cholinergic effects.
In vitro evidence shows that calamus can inhibit acetylcholinesterase (AChE).
Cns Depressants
Theoretically, concurrent use of CNS depressants and calamus might have an additive effect and increase the risk of sedative effects.
Animal research shows that calamus is a CNS depressant and increases gamma-aminobutyric acid levels.

Theoretically, taking calamus with drugs metabolized by CYP2D6 might increase drug levels and potentially increase the risk of adverse effects.
In vitro research shows that calamus extract inhibits CYP2D6 enzyme.
Cytochrome P450 3A4 (Cyp3A4) Substrates
Theoretically, taking calamus with drugs metabolized by CYP3A4 might increase drug levels and potentially increase the risk of adverse effects.
In vitro research shows that calamus extract inhibits CYP3A4 enzyme.
Monoamine Oxidase Inhibitors (Maois)
Theoretically, calamus might potentiate the effects and adverse effects of MAOIs.
Some reports suggest that calamus increases the effects of MAOIs.
Antacids
Theoretically, taking calamus might reduce the effectiveness of antacids.
Some research suggests that calamus lowers gastric pH.
H2-Blockers
Theoretically, taking calamus might reduce the effectiveness of H2-blockers.
Some research suggests that calamus lowers gastric pH.
Proton Pump Inhibitors (Ppis)
Theoretically, taking calamus might reduce the effectiveness of PPIs.
Some research suggests that calamus lowers gastric pH.
Bai-Zhu Atractylodes (root) extract
Anticoagulant/Antiplatelet Drugs
Theoretically, atractylodes might increase the risk of bleeding when used concomitantly with anticoagulant and antiplatelet drugs.
Laboratory research suggests that atractylenolides II and III, constituents of atractylodes, reduce platelet activation. So far, this has not been shown in humans.
Aromatase Inhibitors
Theoretically, atractylodes may have an additive effect when used with other aromatase inhibitors.
Laboratory research suggests that atractylodes and its constituents exhibit aromatase inhibitor effects.
Hexobarbital
Theoretically, taking atractylodes may prolong the therapeutic and adverse effects of hexobarbital.
In animals, atractylodes has been shown to prolong the effects of hexobarbital. These effects have not been shown in humans.
Cytochrome P450 1A2 (Cyp1A2) Substrates
Theoretically, atractylodes might decrease the levels of CYP1A2 substrates.
In animals, atractylodes administered at high doses has been shown to induce CYP1A2 activity. This effect has not been shown in humans.
Cytochrome P450 3A4 (Cyp3A4) Substrates
Theoretically, atractylodes might increase the levels of CYP3A4 substrates.
In animals, atractylodes administered at high doses has been shown to inhibit CYP3A1 activity, which is a homolog to the human CYP3A4 enzyme. This effect has not been shown in humans.
Poria extract
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.
Cholinergic Drugs
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.
Cns Depressants
Theoretically, taking poria mushroom extract may enhance the therapeutic and adverse effects of sedatives.
