HelloPharmacist Scorecard of Clear Heat by Health Concerns
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
Clear Heat contains nine ingredients, one of which is a proprietary herbal blend (so its individual components are listed separately). The active ingredients are licorice root extract, cordyceps fruiting body extract, andrographis leaf extract, kombu leaf extract (a type of seaweed), isatis extract, Japanese honeysuckle flower extract, prunella herb extract, hedyotis herb extract, and dandelion root extract.
The product also contains inactive ingredients: hypromellose, rice bran, and microcrystalline cellulose, which are used as capsule material and fillers.
Does it work?
Not established
The evidence on this product's individual ingredients is mixed and often limited. Licorice root is possibly effective for eczema (atopic dermatitis) and canker sores, but we hold insufficient evidence for its use in Addison disease or asthma.
Cordyceps appears possibly ineffective for athletic performance and has insufficient evidence for sexual dysfunction, arrhythmia, asthma, lung cancer, and COPD. Andrographis is possibly effective for ulcerative colitis, sore throat (tonsillopharyngitis), and osteoarthritis, with insufficient evidence for familial Mediterranean fever.
Kombu is possibly ineffective for abortion or labor induction, with insufficient evidence for cancer, high blood pressure, obesity, and radiation sickness. Isatis is possibly effective for psoriasis but has insufficient evidence for respiratory infections, prostate cancer, ulcerative colitis, hepatitis, and aging skin.
Japanese honeysuckle and dandelion have insufficient evidence for the conditions listed in our data (cognitive decline, respiratory infections, eczema, diabetes, and indigestion for honeysuckle; joint pain, tonsillitis, and swelling for dandelion). We hold no effectiveness data for hedyotis or prunella.
How safe is it?
Well-documented data
Licorice root is generally well tolerated in small food amounts, but high doses or long-term use can cause serious problems. Most common side effects are headache, nausea, and vomiting when taken by mouth; contact dermatitis when applied to skin.
Avoid licorice in pregnancy—glycyrrhizin (its active compound) has been linked to fetal harm—and avoid it while breastfeeding due to insufficient safety data. Cordyceps is generally well tolerated short-term (up to one year in studies), though product quality varies widely.
Common side effects include abdominal discomfort, constipation, and diarrhea; a rare case of liver inflammation has been reported. Avoid cordyceps in pregnancy and breastfeeding due to lack of safety data.
Andrographis is generally well tolerated but more likely to cause side effects at higher doses or beyond 14 days of use; common effects include abdominal discomfort, altered taste, diarrhea, dizziness, fatigue, headache, nausea, rash, and itching, with rare severe allergic reactions including anaphylaxis. Avoid in pregnancy and breastfeeding.
Kombu (laminaria) is generally safe as food but supplements deliver high, variable iodine amounts that may affect the thyroid. Avoid in pregnancy (excess iodine can harm fetal thyroid) and breastfeeding (iodine passes to breast milk and may affect infant thyroid).
Japanese honeysuckle is often used as tea with few reported problems, but high-quality human safety data are limited; rare cases of contact dermatitis and allergic rash have been reported. Avoid in pregnancy and breastfeeding.
Dandelion is generally well tolerated; common side effects include diarrhea, heartburn, and stomach discomfort. Limited safety data exist for concentrated supplements; breastfeeding safety is unclear.
Isatis has limited human safety data and should be avoided in pregnancy and breastfeeding. Hedyotis and prunella have no documented adverse effects on file, but safety data are limited.
Meds to double-check
Moderate interaction found
Before taking Clear Heat, double-check your medications if you take blood thinners or antiplatelet drugs (warfarin, aspirin, clopidogrel, and others)—Moderate interaction risk across multiple ingredients. Also check heart medications like digoxin, amiodarone, or other cardiac glycosides; blood pressure drugs (ACE inhibitors, antihypertensives); diabetes medications; thyroid drugs or thyroid hormone; potassium-sparing diuretics; lithium; immunosuppressants; or quinolone antibiotics.
No interactions are documented for hedyotis or prunella, as we hold no interaction data for those ingredients.
The bottom line
Scorecard at a glanceFormula with limited ingredient disclosure with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.
Clear Heat is a multi-ingredient herbal formula best suited for someone with no active prescriptions or a willingness to verify their exact medications against the interaction list. If you take any heart medications, blood thinners, diabetes drugs, blood pressure pills, immunosuppressants, lithium, thyroid medication, or digoxin, this product requires careful review before starting.
Talk to your pharmacist before use, especially if you're pregnant, breastfeeding, or on long-term medications.

Clear Heat by Health Concerns Drug Interactions
HelloPharmacist Interaction Report
Clear Heat by Health Concerns contains nine ingredients, and several of them interact with medications.
Licorice root extract is the single most serious concern—it carries Moderate-severity interactions with digoxin (a heart medication), which theoretically increases the risk of heart toxicity through potassium loss.
Read the full breakdown — every affected drug type, severity by severity
Licorice also interacts Moderately with blood thinners like warfarin, potentially making them less effective. It may raise levels of certain drugs your liver breaks down (CYP2B6 and CYP2C19 substrates), lower levels of midazolam (a sedative), and pose risks with loop diuretics, chemotherapy drugs like cisplatin and paclitaxel, and heart rhythm medications.
Cordyceps fruiting body extract interacts Moderately with blood thinners and antiplatelet drugs (raising bleeding risk), immunosuppressants, and has a Minor interaction with testosterone. Andrographis leaf extract carries Moderate interactions with blood pressure drugs, blood thinners, and immunosuppressants, plus Minor interactions with certain pain relievers (etoricoxib, celecoxib) and the diabetes drug glipizide.
Kombu leaf extract (a seaweed) interacts Moderately with several drugs because of its potassium and iodine content: potassium-sparing diuretics, ACE inhibitors, digoxin, antithyroid drugs, thyroid hormone, and amiodarone. Japanese honeysuckle flower extract has a Moderate interaction with blood thinners.
Dandelion root extract interacts Moderately with blood thinners, diabetes drugs, potassium-sparing diuretics, lithium, some antibiotics, and drugs your liver processes via a specific pathway (CYP1A2 and glucuronidated drugs). Isatis extract has no documented interactions.
We could not check Hedyotis herb extract or Prunella herb extract.
Altogether, these interactions span 1,284 individual medications. Use the medication checker on this page to look up your exact drugs before starting.

For each ingredient in Clear Heat with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.
Licorice root extract
Antihypertensive Drugs
Theoretically, licorice might reduce the effects of antihypertensive drugs.
In human research, licorice increases blood pressure in a dose-dependent manner.
Cisplatin (Platinol-Aq)
Theoretically, licorice might reduce the effects of cisplatin.
In animal research, licorice diminished the therapeutic efficacy of cisplatin.
Corticosteroids
Theoretically, concomitant use of licorice and corticosteroids might increase the side effects of corticosteroids.
Case reports suggest that concomitant use of licorice and oral corticosteroids, such as hydrocortisone, can potentiate the duration of activity and increase blood levels of corticosteroids. Additionally, in one case report, a patient with neurogenic orthostatic hypertension stabilized on fludrocortisone 0.1 mg twice daily developed pseudohyperaldosteronism after recent consumption of large amounts of black licorice.
Cytochrome P450 2B6 (Cyp2B6) Substrates
Theoretically, licorice might increase levels of drugs metabolized by CYP2B6.
In vitro research shows that licorice extract and glabridin, a licorice constituent, inhibit CYP2B6 isoenzymes. Licorice extract from the species G. uralensis seems to inhibit CYP2B6 isoenzymes to a greater degree than G. glabra extract in vitro. Theoretically, these species of licorice might increase levels of drugs metabolized by CYP2B6; however, these interactions have not yet been reported in humans.
Cytochrome P450 2C19 (Cyp2C19) Substrates
Theoretically, licorice might increase levels of drugs metabolized by CYP2C19.
In vitro, licorice extracts from the species G. glabra and G. uralensis inhibit CYP2C19 isoenzymes in vitro. Theoretically, these species of licorice might increase levels of drugs metabolized by CYP2C19; however, this interaction has not yet been reported in humans.
Cytochrome P450 2C8 (Cyp2C8) Substrates
Theoretically, licorice might increase levels of drugs metabolized by CYP2C8.
In vitro, licorice extract from the species G. glabra and G. uralensis inhibits CYP2C8 isoenzymes. Theoretically, these species of licorice might increase levels of drugs metabolized by CYP2C8; however, this interaction has not yet been reported in humans.
Cytochrome P450 2C9 (Cyp2C9) Substrates
Theoretically, licorice might increase or decrease levels of drugs metabolized by CYP2C9.
There is conflicting evidence about the effect of licorice on CYP2C9 enzyme activity. In vitro research shows that extracts from the licorice species G. glabra and G. uralensis moderately inhibit CYP2C9 isoenzymes. However, evidence from an animal model shows that licorice extract from the species G. uralensis can induce hepatic CYP2C9 activity. Until more is known, licorice should be used cautiously in people taking CYP2C9 substrates.
Cytochrome P450 3A4 (Cyp3A4) Substrates
Theoretically, licorice might increase or decrease levels of drugs metabolized by CYP3A4.
Pharmacokinetic research shows that the licorice constituent glycyrrhizin, taken in a dosage of 150 mg orally twice daily for 14 days, modestly decreases the area under the concentration-time curve of midazolam by about 20%. Midazolam is a substrate of CYP3A4, suggesting that glycyrrhizin modestly induces CYP3A4 activity. Animal research also shows that licorice extract from the species G. uralensis induces CYP3A4 activity. However, licorice extract from G. glabra species appear to inhibit CYP3A4-induced metabolism of testosterone in vitro. It is thought that the G. glabra inhibits CYP3A4 due to its constituent glabridin, which is a moderate CYP3A4 inhibitor in vitro and not present in other licorice species. Until more is known, licorice should be used cautiously in people taking CYP3A4 substrates.
Digoxin (Lanoxin)
Theoretically, concomitant use of licorice with digoxin might increase the risk of cardiac toxicity.
Overuse or misuse of licorice with cardiac glycoside therapy might increase the risk of cardiac toxicity due to potassium loss.
Diuretic Drugs
Theoretically, concomitant use of licorice with diuretic drugs might increase the risk of hypokalemia.
Overuse of licorice might compound diuretic-induced potassium loss. In one case report, a 72-year-old male with a past medical history of hypertension, type 2 diabetes, hyperlipidemia, arrhythmia, stroke, and hepatic dysfunction was hospitalized with severe hypokalemia and uncontrolled hypertension due to pseudohyperaldosteronism. This was thought to be provoked by concomitant daily consumption of a product containing 225 mg of glycyrrhizin, a constituent of licorice, and hydrochlorothiazide 12.5 mg for 1 month.
Estrogens
Theoretically, licorice might increase or decrease the effects of estrogen therapy.
Theoretically, licorice might interfere with estrogen therapy due to estrogenic and anti-estrogenic effects.
Loop Diuretics
Theoretically, loop diuretics might increase the mineralocorticoid effects of licorice.
Theoretically, loop diuretics might enhance the mineralocorticoid effects of licorice by inhibiting the enzyme that converts cortisol to cortisone; however, bumetanide (Bumex) does not appear to have this effect.
Midazolam (Versed)
Theoretically, licorice might decrease levels of midazolam.
In humans, the licorice constituent glycyrrhizin appears to moderately induce the metabolism of midazolam. This is likely due to induction of cytochrome P450 3A4 by licorice. Until more is known, licorice should be used cautiously in people taking midazolam.
P-Glycoprotein Substrates
Theoretically, licorice might decrease the absorption of P-glycoprotein substrates.
In vitro research shows that licorice can increase P-glycoprotein activity.
Paclitaxel (Abraxane, Onxol)
Theoretically, licorice might decrease plasma levels and clinical effects of paclitaxel.
Multiple doses of licorice taken concomitantly with paclitaxel might reduce the effectiveness of paclitaxel. Animal research shows that licorice 3 grams/kg given orally for 14 days before intravenous administration of paclitaxel decreases the exposure to paclitaxel and increases its clearance. Theoretically, this occurs because licorice induces cytochrome P450 3A4 enzymes, which metabolize paclitaxel. Notably, a single dose of licorice did not affect exposure or clearance of paclitaxel.
Warfarin (Coumadin)
Theoretically, licorice might decrease plasma levels and clinical effects of warfarin.
Licorice seems to increase metabolism and decrease levels of warfarin in animal models. This is likely due to induction of cytochrome P450 2C9 (CYP2C9) metabolism by licorice. Advise patients taking warfarin to avoid taking licorice.
Cytochrome P450 1A2 (Cyp1A2) Substrates
Theoretically, licorice might decrease the levels and clinical effects of CYP1A2 substrates.
In vitro research shows that licorice induces CYP1A2 enzymes.
Methotrexate (Trexall, Others)
Theoretically, licorice might increase levels of methotrexate.
Animal research suggests that intravenous administration of glycyrrhizin, a licorice constituent, and high-dose methotrexate may delay methotrexate excretion and increase systemic exposure, leading to transient elevations in liver enzymes and total bilirubin. This interaction has not yet been reported in humans.
Dandelion Root Extract
Anticoagulant/Antiplatelet Drugs
Theoretically, taking dandelion root along with anticoagulant or antiplatelet drugs might increase the risk of bruising and bleeding.
In vitro research suggests that dandelion root inhibits platelet aggregation.
Antidiabetes Drugs
Theoretically, dandelion might increase the risk for hypoglycemia when used with antidiabetes drugs.
Laboratory research suggests that dandelion extract may have moderate alpha-glucosidase inhibitor activity and might also increase insulin secretion. Also, in a case report, a 58-year-old woman with type 2 diabetes who was being treated with insulin developed hypoglycemia 2 weeks after beginning to eat salads containing dandelion.
Cytochrome P450 1A2 (Cyp1A2) Substrates
Theoretically, dandelion might increase levels of drugs metabolized by CYP1A2.
Laboratory research suggests that dandelion might inhibit CYP1A2. So far, this interaction has not been reported in humans. However, until more is known, watch for an increase in the levels of drugs metabolized by CYP1A2 in patients taking dandelion.
Glucuronidated Drugs
Theoretically, dandelion might increase the clearance of drugs that are UDP-glucuronosyltransferase substrates.
There is some preliminary evidence that dandelion might induce UDP-glucuronosyltransferase, a phase II enzyme.
Lithium
Theoretically, through diuretic effects, dandelion might reduce excretion and increase levels of lithium.
Animal research suggests that dandelion has diuretic properties. As diuretics can increase serum lithium levels, the dose of lithium might need to be decreased when taken with dandelion.
Potassium-Sparing Diuretics
Theoretically, dandelion might increase the risk of hyperkalemia when taken with potassium-sparing diuretics.
Dandelion contains significant amounts of potassium.
Quinolone Antibiotics
Theoretically, dandelion might lower fluoroquinolone levels.
Animal research shows that dandelion reduces absorption of ciprofloxacin and can lower levels by 73%. However, this effect has not been reported in humans.
Andrographis leaf extract
Anticoagulant/Antiplatelet Drugs
Theoretically, andrographis might increase the risk of bleeding when used with anticoagulant or antiplatelet drugs.
Animal and laboratory studies suggest that andrographis has antiplatelet effects.
Antihypertensive Drugs
Theoretically, andrographis might increase the risk of hypotension when used with antihypertensive drugs.
Animal research suggests that andrographis has hypotensive effects.
Immunosuppressants
Theoretically, andrographis might interfere with the effects of immunosuppressive drugs.
Laboratory research suggests that andrographolide has immunostimulant activity.
Celecoxib (Celebrex)
Theoretically, andrographis extract might increase the maximum concentration and time to peak concentration of celecoxib. The clinical significance of these changes is unclear.
Animal research suggests that andrographis extract taken orally increases the maximum concentration and time to peak concentration of celecoxib but does not appear to impact the area under the curve.
Etoricoxib (Arcoxia)
Theoretically, andrographis might decrease the absorption of etoricoxib, although the clinical significance is unclear.
Animal research shows that andrographis extract, or the constituent andrographolide, taken orally with etoricoxib decreases the bioavailability of etoricoxib. However, this reduced bioavailability is not correlated with a reduction in the anti-inflammatory effects of etoricoxib in arthritic mice models. The clinical significance of this interaction is unclear.
Glipizide (Glucotrol)
Theoretically, andrographis extract might increase the maximum concentration and area under the curve of glipizide; however, opposite effects are seen with the constituent, andrographolide. The clinical significance of this interaction is unclear.
Animal research suggests that andrographis extract taken orally with glipizide in diabetes-induced rats increases the maximum concentration and area under the curve of glipizide. However, the opposite effect is seen with the constituent, andrographolide, in which the maximum concentration and area under the curve are decreased when taken with glipizide.
Cordyceps Fruiting Body Extract
Anticoagulant/Antiplatelet Drugs
Theoretically, cordyceps may increase the risk of bleeding when used with antiplatelet or anticoagulant drugs.
In vitro and animal research suggests that cordyceps extract inhibits platelet aggregation and function. However, this interaction has not been reported in humans.
Immunosuppressants
Theoretically, concurrent use of cordyceps might interfere with immunosuppressive therapy.
Animal and in vitro research suggests that cordyceps stimulates the immune system. However, limited clinical research suggests that taking cordyceps may lower the necessary therapeutic dose of the immunosuppressant cyclosporine, which suggests that cordyceps may have an immunosuppressive effect.
Testosterone
Theoretically, concurrent use of cordyceps and testosterone might have additive effects.
Animal research suggests that cordyceps can increase testosterone levels. The clinical significance of this finding is unclear.
Japanese Honeysuckle flower extract
Anticoagulant/Antiplatelet Drugs
Theoretically, honeysuckle might increase the risk of bleeding when taken with anticoagulant or antiplatelet drugs.
In vitro research shows that polyphenols extracted from honeysuckle can inhibit platelet aggregation.
Kombu Leaf Extract
Ace Inhibitors (Aceis)
Theoretically, laminaria might increase the risk of hyperkalemia when taken with ACEIs.
Laminaria contains potassium.
Amiodarone (Cordarone)
Theoretically, combining laminaria with amiodarone might cause excessively high iodine levels.
Amiodarone contains 37.3% iodine and can increase iodine levels. Concomitant use with laminaria supplements, some of which may contain as much as 1000 mcg iodine, might increase the risk of adverse effects from iodine, including altered thyroid function.
Antithyroid Drugs
Due to its iodine content, laminaria might alter the effects of antithyroid drugs.
Some laminaria supplements contain up to 1000 mcg of iodine. Iodine in high doses has been reported to cause both hyperthyroidism and hypothyroidism, depending on the individual's past medical history. Taking laminaria could theoretically alter the effects of antithyroid drugs.
Digoxin (Lanoxin)
Theoretically, laminaria might increase the risk of hyperkalemia, which could increase the effects and adverse effects of digoxin.
Laminaria contains potassium.
Potassium-Sparing Diuretics
Theoretically, laminaria might increase the risk of hyperkalemia when taken with potassium-sparing diuretics.
Laminaria contains potassium.
Thyroid Hormone
Due to its iodine content, laminaria might alter the effects of thyroid hormone.
Some laminaria supplements contain up to 1000 mcg of iodine. Iodine in high doses has been reported to cause both hyperthyroidism and hypothyroidism, depending on the individual's past medical history. Taking laminaria could theoretically alter the effects of thyroid hormone.
