HelloPharmacist Scorecard of Herb Fuel by Herbally Grounded
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
Herb Fuel contains 7 active ingredients in a proprietary blend: Holy Basil, Cordyceps (a medicinal fungus), Schisandra (also called schizandra berry), Astragalus (an adaptogenic herb), Ashwagandha (another adaptogenic herb), Reishi Mushroom, and Amla (Indian Gooseberry). The blend also includes cellulose, an inactive binder.
These herbs are traditional tonics used in various systems of medicine to support stress resilience, immunity, and energy—though the clinical evidence for most of these claims remains limited or incomplete.
Does it work?
Moderate evidence
The evidence supporting Herb Fuel's ingredients is mixed and mostly thin. Ashwagandha shows the strongest data: it is rated Possibly Effective for insomnia, anxiety, stress, and generalized anxiety disorder.
Amla (Indian Gooseberry) is rated Possibly Effective for acid reflux (GERD) and abnormal cholesterol (dyslipidemia). For the other ingredients—Holy Basil, Cordyceps, Schisandra, Astragalus, and Reishi Mushroom—the evidence we hold is insufficient to rate their effectiveness for any claimed use.
Cordyceps is actually rated Possibly Ineffective for athletic performance, and Reishi Mushroom is rated Possibly Ineffective for high cholesterol. If you're considering this product for a specific health goal, talk with your pharmacist about whether the ingredients have solid support for that use.
How safe is it?
Well-documented data
Most of these herbs are generally well tolerated short-term in healthy adults, but long-term safety data are limited for all of them. Common side effects are mild: Holy Basil and Ashwagandha may cause nausea, loose stools, or diarrhea; Schisandra may cause heartburn, stomach upset, or decreased appetite; Cordyceps may cause constipation, diarrhea, or abdominal discomfort; Reishi Mushroom may cause dizziness, dry mouth, nausea, or rash; Amla may cause stomach discomfort in a small number of users.
Importantly, all ingredients are rated Possibly Unsafe or best avoided during pregnancy, and none have enough safety data to recommend during breastfeeding. Additionally, ashwagandha and cordyceps carry rare but documented case reports of liver injury—and ashwagandha has a case report linking it to potentially serious blood vessel changes in the brain.
Holy Basil and schisandra carry theoretical concerns about uterine stimulation during pregnancy. If you are pregnant, breastfeeding, or have liver disease, talk with your pharmacist or doctor before starting this product.
Meds to double-check
Moderate interaction found
Before taking Herb Fuel, double-check with your pharmacist if you take any of the following: blood thinners or antiplatelet drugs (warfarin, clopidogrel, aspirin); diabetes medications; blood pressure drugs; CNS depressants or benzodiazepines; thyroid hormone; immunosuppressants or cyclophosphamide; lithium; or any drug cleared by the liver (especially those processed by CYP3A4, CYP2C9, CYP2C19, or P-glycoprotein). Altogether, these interactions span 1,464 individual medications.
The bottom line
Scorecard at a glanceFormula with limited ingredient disclosure with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
Herb Fuel might appeal to someone seeking stress or anxiety support (ashwagandha has the most evidence), or to someone trying to manage reflux or cholesterol naturally (amla has some backing). However, if you take any blood thinners, diabetes drugs, blood pressure medications, sedatives, immunosuppressants, thyroid hormone, or lithium, you should not use this product without checking each of your exact medications first using the tool on this page.
If you're pregnant, breastfeeding, or have liver concerns, talk with your pharmacist before considering it.

Herb Fuel by Herbally Grounded Drug Interactions
HelloPharmacist Interaction Report
Herb Fuel by Herbally Grounded contains seven active ingredients, and several of them interact with medications.
The most serious interactions are Moderate in severity.
Read the full breakdown — every affected drug type, severity by severity
Schisandra poses the broadest interaction risk: it inhibits or induces liver enzymes (CYP3A4, CYP2C19, CYP2C9) and P-glycoprotein transporters that clear many drugs, potentially raising levels of medications like tacrolimus, midazolam, voriconazole, and cyclophosphamide, or lowering levels of warfarin. Ashwagandha interacts with CNS depressants (sedatives, benzodiazepines), antihypertensive drugs, antidiabetes drugs, thyroid hormone, immunosuppressants, and hepatotoxic drugs—meaning it may amplify drowsiness, lower blood pressure excessively, raise blood sugar lows, or boost thyroid hormone effects to unsafe levels.
Holy Basil, Cordyceps, Astragalus, Reishi Mushroom, and Amla (Indian Gooseberry) all interact with blood thinners (anticoagulants and antiplatelet agents) and antidiabetes drugs, theoretically increasing bleeding risk and low blood sugar risk respectively.
Cordyceps and Astragalus also affect immunosuppressants, potentially interfering with transplant rejection prevention or cancer chemotherapy. Holy Basil may heighten the sedative effect of pentobarbital.
Astragalus may raise lithium levels. Ashwagandha carries a documented risk of liver damage when combined with hepatotoxic drugs.
Additionally, we could not check interaction data for the Proprietary Blend itself, since its component proportions are not disclosed. Use the medication checker on this page to verify your exact prescriptions before starting.

Ashwagandha
Antidiabetes Drugs
Theoretically, taking ashwagandha with antidiabetes drugs might increase the risk of hypoglycemia.
There is preliminary clinical evidence suggesting that ashwagandha might lower blood glucose levels. Theoretically, ashwagandha might have additive effects when used with antidiabetes drugs and increase the risk of hypoglycemia.
Antihypertensive Drugs
Theoretically, taking ashwagandha with antihypertensive drugs might increase the risk of hypotension.
Animal research suggests that ashwagandha might lower systolic and diastolic blood pressure. Theoretically, ashwagandha might have additive effects when used with antihypertensive drugs and increase the risk of hypotension.
Benzodiazepines
Theoretically, taking ashwagandha might increase the sedative effects of benzodiazepines.
There is preliminary evidence that ashwagandha might have an additive effect with diazepam (Valium) and clonazepam (Klonopin). This may also occur with other benzodiazepines.
Cns Depressants
Theoretically, taking ashwagandha might increase the sedative effects of CNS depressants.
Ashwagandha seems to have sedative effects. Theoretically, this may potentiate the effects of barbiturates, other sedatives, and anxiolytics.
Hepatotoxic Drugs
Theoretically, taking ashwagandha with hepatotoxic drugs might increase the risk of liver damage.
Ashwagandha has been linked to cases of acute hepatitis, liver failure, hepatic encephalopathy, autoimmune hepatitis, the need for liver transplantation, and death due to liver failure.
Immunosuppressants
Theoretically, taking ashwagandha might decrease the effects of immunosuppressants.
Ashwagandha has demonstrated immunostimulant effects in humans. Animal research has shown that ashwagandha can attenuate the immunosuppression caused by cyclophosphamide.
Thyroid Hormone
Ashwagandha might increase the effects and adverse effects of thyroid hormone.
Concomitant use of ashwagandha with thyroid hormones may cause additive therapeutic and adverse effects. Preliminary clinical research and animal studies suggest that ashwagandha boosts thyroid hormone synthesis and secretion. In one clinical study, ashwagandha increased triiodothyronine (T3) and thyroxine (T4) levels by 41.5% and 19.6%, respectively, and reduced serum TSH levels by 17.4% from baseline in adults with subclinical hypothyroidism.
Cytochrome P450 1A2 (Cyp1A2) Substrates
Theoretically, ashwagandha might decrease the levels and clinical effects of CYP1A2 substrates.
In vitro research shows that ashwagandha extract induces CYP1A2 enzymes.
Cytochrome P450 3A4 (Cyp3A4) Substrates
Theoretically, ashwagandha might decrease the levels and clinical effects of CYP3A4 substrates.
In vitro research shows that ashwagandha extract induces CYP3A4 enzymes.
Serotonergic Drugs
Some animal studies have reported that ashwagandha can enhance serotonergic transmission by altering certain serotonin (5-HT) receptors. However, there is no evidence to suggest that ashwagandha increases the risk of serotonin-related effects, and there have been no published case reports of serotonin syndrome when combined with other serotonergic drugs. Nevertheless, due to the lack of extensive studies on the matter and the fact that ashwagandha appears to affect serotonergic pathways, it would be prudent to exercise caution when combining it with drugs that affect serotonin.

Schisandra
Cyclophosphamide
Theoretically, schisandra might increase the levels and clinical effects of cyclophosphamide.
In vitro research shows that schisandra increases the concentration of cyclophosphamide, likely through inhibition of cytochrome P450 3A4. After multiple doses of the schisandra constituents schisandrin A and schisantherin A, the maximum concentration of cyclophosphamide was increased by 7% and 75%, respectively, while the overall exposure to cyclophosphamide was increased by 29% and 301%, respectively.
Cyclosporine (Neoral, Sandimmune)
Schisandra can increase the levels and clinical effects of cyclosporine.
A small observational study in children with aplastic anemia found that taking schisandra with cyclosporine increased cyclosporine trough levels by 93% without increasing the risk of adverse events. However, the dose of cyclosporine was reduced in 9% of children to maintain appropriate cyclosporine blood concentrations.
Cytochrome P450 2C19 (Cyp2C19) Substrates
Theoretically, schisandra might increase the levels and clinical effects of CYP2C19 substrates.
In vitro research shows that schisandra inhibits CYP2C19, and animal research shows that schisandra increases the concentration of voriconazole, a CYP2C19 substrate. Theoretically, schisandra may also inhibit the metabolism of other CYP2C19 substrates. This effect has not been reported in humans.
Cytochrome P450 2C9 (Cyp2C9) Substrates
Theoretically, schisandra might decrease the levels and clinical effects of CYP2C9 substrates.
In vitro and animal research suggests that schisandra induces CYP2C9 enzymes. This effect has not been reported in humans.
Cytochrome P450 3A4 (Cyp3A4) Substrates
Schisandra can increase the levels and clinical effects of drugs metabolized by CYP3A4.
Most clinical and laboratory research shows that schisandra, administered either as a single dose or up to twice daily for 14 days, inhibits CYP3A4 and increases the concentration of CYP3A4 substrates such as cyclophosphamide, midazolam, tacrolimus, and talinolol. Although one in vitro and animal study shows that schisandra may induce CYP3A4 metabolism, this effect appears to be overpowered by schisandra's CYP3A4 inhibitory activity and has not been reported in humans.
Midazolam (Versed)
Schisandra can increase the levels and clinical effects of midazolam.
A small pharmacokinetic study in healthy adults shows that taking schisandra extract (Hezheng Pharmaceutical Co.) containing deoxyschizandrin 33.75 mg twice daily for 8 days and a single dose of midazolam 15 mg on day 8 increases the overall exposure to midazolam by about 119%, increases the peak plasma level of midazolam by 86%, and decreases midazolam clearance by about 52%. This effect has been attributed to inhibition of CYP3A4 by schisandra.
P-Glycoprotein Substrates
Schisandra might increase the levels and clinical effects of P-glycoprotein substrates.
In vitro research shows that schisandra extracts and constituents such as schisandrin B inhibit P-glycoprotein mediated efflux in intestinal cells and in P-glycoprotein over-expressing cell lines. Additionally, a small clinical study shows that schisandra increases the peak concentration and overall exposure to talinolol, a P-glycoprotein probe substrate. Theoretically, schisandra might inhibit the efflux of other P-glycoprotein substrates.
Sirolimus (Rapamune)
Schisandra can increase the levels and clinical effects of sirolimus.
A small pharmacokinetic study in healthy volunteers shows that taking 3 capsules of schisandra (Hezheng Pharmaceutical Company) containing a total of 33.75 mg deoxyschizandrin twice daily for 13 days and then taking a single dose of sirolimus 2 mg increases the overall exposure and peak level of sirolimus by two-fold. This effect is thought to be due to inhibition of cytochrome P450 3A4 by schisandra, as well as possible inhibition of the P-glycoprotein drug transporter.
Tacrolimus (Prograf)
Schisandra can increase the levels and clinical effects of tacrolimus.
Clinical research in healthy children and adults, transplant patients, and patients with nephrotic syndrome and various rheumatic immunologic disorders shows that taking schisandra with tacrolimus increases tacrolimus peak levels by 183% to 268%, prolongs or delays time to peak tacrolimus concentrations, increases overall exposure to tacrolimus by 126% to 343%, and decreases tacrolimus clearance by 19% to 73%. This effect is thought to be due to inhibition of P-glycoprotein drug transporter and CYP3A4 and CYP3A5 by schisandra. Some clinical and observational studies suggest that schisandra increases tacrolimus levels similarly in both expressors and non-expressors of CYP3A5, while other studies suggest it does so to a greater degree in CYP3A5 expressors than non-expressors. Animal research suggests that the greatest increase in tacrolimus levels occurs when schisandra is taken either concomitantly or up to 2 hours before tacrolimus, and clinical and observational research in humans suggests that schisandra may increase whole blood levels of tacrolimus and decrease clearance of tacrolimus in a dose-dependent manner.
Talinolol
Schisandra can increase the levels and clinical effects of talinolol.
A small pharmacokinetic study in healthy volunteers shows that taking schisandra extract 300 mg twice daily for 14 days with a single dose of talinolol 100 mg on day 14 increases the peak talinolol level by 51% and the overall exposure to talinolol by 47%. This effect is thought to be due to the possible inhibition of cytochrome P450 3A4 and P-glycoprotein by schisandra.
tly.
Voriconazole (Vfend)
Theoretically, schisandra might increase the levels and clinical effects of voriconazole.
Animal research shows that oral schisandra given daily for 1 or 14 days increases levels of intravenously administered voriconazole, a cytochrome P450 (CYP) 2C19 substrate. This effect is thought to be due to inhibition of CYP2C19 by schisandra. However, this interaction has not been reported in humans.
Warfarin (Coumadin)
Theoretically, schisandra might decrease the levels and clinical effects of warfarin.
Animal research suggests that oral schisandra extract, given daily for 6 days, reduces levels of intravenously administered warfarin. This effect might be due to the induction of cytochrome P450 (CYP) 2C9 metabolism by schisandra. However, this interaction has not been reported in humans.
Reishi Mushroom
Anticoagulant/Antiplatelet Drugs
Theoretically, high doses of reishi mushroom might increase the risk of bleeding.
A dose of 1.5 grams daily of reishi mushroom does not seem to decrease platelet aggregation, but a higher dose of 3 grams daily does.
Antidiabetes Drugs
Theoretically, reishi mushroom might have additive effects with antidiabetes drugs.
Animal research suggests that reishi mushroom decreases blood sugar. However, in patients with type 2 diabetes, taking reishi mushroom does not reduce fasting glucose levels, and its effects on glycated hemoglobin are inconsistent.
Antihypertensive Drugs
Theoretically, concurrent use of reishi mushroom with antihypertensive drugs might increase the risk of hypotension.
Reishi mushroom has shown hypotensive activity in animal research. Clinical evidence suggests that reishi mushroom reduces blood pressure in some, but not all, patients with hypertension.
Cordyceps
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.
Holy Basil
Anticoagulant/Antiplatelet Drugs
Theoretically, holy basil seed oil might increase the risk of bleeding when used with anticoagulant or antiplatelet drugs.
Animal research shows that holy basil seed oil can prolong bleeding time, possibly due to inhibition of platelet aggregation. However, it is not known if this occurs in humans.
Antidiabetes Drugs
Theoretically, holy basil might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Small clinical studies show that taking holy basil can decrease fasting blood glucose and other measures of glycemic control in patients with type 2 diabetes.
Pentobarbital (Nembutal)
Theoretically, holy basil seed oil might increase the sedative effects of pentobarbital.
Animal research shows that holy basil seed oil increases pentobarbitone-induced sleeping time. However, it is not known if this occurs in humans or if this applies to other barbiturates or sedatives.
Astragalus
Antidiabetes Drugs
Theoretically, taking astragalus with antidiabetes drugs might increase the risk of hypoglycemia.
Clinical research in humans shows that astragalus might have hypoglycemic effects. Theoretically, taking astragalus, especially in combination with other hypoglycemic agents, might increase the risk of hypoglycemia.
Cyclophosphamide
Theoretically, astragalus might interfere with cyclophosphamide therapy.
Evidence regarding the effect of astragalus on immunosuppression caused by cyclophosphamide is conflicting. Some animal research suggests that astragalus reverses cyclophosphamide-induced immunosuppression. However, other animal research shows no effect.
Immunosuppressants
Theoretically, astragalus might interfere with immunosuppressive therapy.
Astragalus seems to stimulate immune function. Theoretically, taking astragalus might decrease the effects of immunosuppressive therapy.
Lithium
Theoretically, astragalus might increase levels and adverse effects of lithium.
Animal research suggests that astragalus has diuretic properties. Theoretically, due to this diuretic effect, astragalus might reduce excretion and increase levels of lithium.
Amla
Anticoagulant/Antiplatelet Drugs
Theoretically, Indian gooseberry may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs; however, research is conflicting.
Clinical research shows that taking Indian gooseberry 500 mg as a single dose or twice daily for 10 days reduces platelet aggregation by about 24% to 36%, increases bleeding time by about 3.8-5.9 seconds, and increases clotting time by about 9.8-12.7 seconds when compared to baseline. However, taking Indian gooseberry 500 mg along with clopidogrel 75 mg or ecosprin 75 mg, as a single dose or for 10 days, does not significantly reduce platelet aggregation or increase bleeding time or clotting time when compared with clopidogrel 75 mg or ecosprin 75 mg alone. Until more is known, use caution when taking Indian gooseberry in combination with anticoagulant/antiplatelet drugs.
Antidiabetes Drugs
Taking Indian gooseberry with antidiabetes drugs might increase the risk of hypoglycemia.
Clinical research shows that taking Indian gooseberry fruit or fruit extract alone or in conjunction with antidiabetes medications can lower blood glucose levels. Dose adjustments to diabetes medications might be necessary.
Aspirin
Theoretically, Indian gooseberry may increase the risk of bleeding if used with aspirin; however, research is conflicting.
Clinical research shows that taking Indian gooseberry 500 mg as a single dose or twice daily for 10 days reduces platelet aggregation by about 24% to 36%, increases bleeding time by about 3.8-5.9 seconds, and increases clotting time by about 9.8-12.7 seconds when compared to baseline. However, taking a single dose of Indian gooseberry 500 mg along with ecosprin 75 mg, or taking a combination of Indian gooseberry 500 mg twice daily plus ecosprin 75 mg once daily for 10 days, does not significantly reduce platelet aggregation or increase bleeding time or clotting time when compared with ecosprin 75 mg alone.
Clopidogrel (Plavix)
Theoretically, Indian gooseberry may increase the risk of bleeding if used with clopidogrel; however, research is conflicting.
Clinical research shows that taking Indian gooseberry 500 mg as a single dose or twice daily for 10 days reduces platelet aggregation by about 24% to 36%, increases bleeding time by about 3.8-5.9 seconds, and increases clotting time by about 9.8-12.7 seconds when compared to baseline. However, taking a single dose of Indian gooseberry 500 mg along with clopidogrel 75 mg, or taking a combination of Indian gooseberry 500 mg twice daily plus clopidogrel 75 mg once daily for 10 days, does not significantly reduce platelet aggregation or increase bleeding time or clotting time when compared with clopidogrel 75 mg alone.
