What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 13 active ingredients.
  • “Proprietary Herbal Blend” is a proprietary blend — the label gives one combined amount (1,200 mg) without saying how much of each component you get.

Fertile Garden contains 13 ingredients, including Licorice Root Extract, Dong Quai root extract, Chinese Dodder seed extract, Ashwagandha Root Extract, Lycium (Goji), Chinese Peony Root Extract, Shatavari root extract, and Poria Sclerotium Extract. There is also a Proprietary Herbal Blend (whose individual components are listed separately) and several ingredients we cannot check: Loranthus Stem Extract, Pseudostellaria Root Extract, Melia Fruit Extract, Glehnia root extract, and Ligustrum fruit extract.

The capsules also contain inactive ingredients: hypromellose and rice.

Does it work?

Moderate evidence
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
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: Women's reproductive health and fertility support.
  • We looked for evidence on: Dysmenorrhea, Anxiety, Fatigue, Menstrual regulation, Reproductive wellness, Hormonal balance.
  • The strongest evidence on file: Ashwagandha is rated "Possibly Effective" for Anxiety (Natural Medicines).
  • Also on file: Ashwagandha is rated "Possibly Effective" for Generalized anxiety disorder (GAD).
  • Also on file: Peony is rated "Insufficient Reliable Evidence To Rate" for Chronic fatigue syndrome (CFS), Dysmenorrhea.

The evidence for most ingredients in this formula is limited. Licorice Root Extract is rated possibly effective for canker sores and atopic dermatitis (eczema), but has insufficient evidence for Addison disease and asthma.

Ashwagandha Root Extract is possibly effective for insomnia, anxiety, stress, and generalized anxiety disorder, though evidence for bipolar disorder is insufficient. All other ingredients — Dong Quai, Chinese Dodder, Goji, Chinese Peony, Shatavari, and Poria — lack sufficient evidence to establish their effectiveness for the conditions tested.

We don't hold effectiveness ratings for the Proprietary Herbal Blend or the ingredients we couldn't check.

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 7 of the 8 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 8 of 8.
  • General safety write-ups exist for 8 of 8.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Licorice Root Extract is generally well tolerated in food amounts, but the active compound glycyrrhizin can cause serious problems at high doses or with long-term use. Most common side effects are headache, nausea, and vomiting.

Avoid licorice in pregnancy — glycyrrhizin has been linked to harmful effects — and while breastfeeding, where safety data are insufficient. Dong Quai is generally well tolerated but may increase bleeding risk and cause skin sensitivity to sunlight; it may stimulate the uterus, so avoid it in pregnancy and during breastfeeding due to lack of safety data.

Ashwagandha is generally well tolerated short-term in healthy adults, though diarrhea, nausea, and vomiting can occur at higher doses; it's traditionally thought to risk miscarriage, so avoid in pregnancy and while breastfeeding. Goji is generally safe as a food but has less safety data in concentrated supplement form; avoid medicinal amounts in pregnancy and use caution while breastfeeding.

Chinese Peony and Poria are generally well tolerated short-term but have limited safety data; both should be avoided in pregnancy and while breastfeeding. Chinese Dodder and Shatavari have limited human safety data; dodder should be avoided in pregnancy and breastfeeding, and shatavari's safety in pregnancy is not well established.

Ashwagandha Root Extract10 drug types · 1,372 drugs

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.

Likelihood Possible Evidence B
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

Likelihood Probable Evidence B
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

Licorice Root Extract18 drug types · 1,040 drugs

Antihypertensive Drugs

Theoretically, licorice might reduce the effects of antihypertensive drugs.
In human research, licorice increases blood pressure in a dose-dependent manner.

Likelihood Possible Evidence B
Cisplatin (Platinol-Aq)

Theoretically, licorice might reduce the effects of cisplatin.
In animal research, licorice diminished the therapeutic efficacy of cisplatin.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence B
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence B
P-Glycoprotein Substrates

Theoretically, licorice might decrease the absorption of P-glycoprotein substrates.
In vitro research shows that licorice can increase P-glycoprotein activity.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

Lycium8 drug types · 1,000 drugs

Warfarin (Coumadin)

Goji can increase the effects of warfarin and possibly increase the risk of bleeding.
There are at least 5 case reports of increased international normalized ratio (INR) in patients stabilized on warfarin who began drinking goji juice, concentrated goji tea, or goji wine. Goji may inhibit the metabolism of warfarin by cytochrome P450 2C9 (CYP2C9).

Likelihood Probable Evidence D
Antihypertensive Drugs

Theoretically, concomitant use of goji root bark, but not goji fruit, with antihypertensive drugs might have additive effects.
Animal and in vitro research suggest that goji root bark has hypotensive effects. However, goji fruit juice does not appear to reduce systolic or diastolic blood pressure in humans.

Likelihood Possible Evidence D
Cytochrome P450 2C19 (Cyp2C19) Substrates

Theoretically, goji berry might inhibit CYP2C19 and reduce metabolism of CYP2C19 substrates.
In vitro research shows that goji berry tincture and juice inhibit CYP2C19 enzymes. Concomitant use with goji may decrease metabolism and increase levels of CYP2C19 substrates. However, this has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2C9 (Cyp2C9) Substrates

Theoretically, goji berry might inhibit CYP2C9 and reduce metabolism of CYP2C9 substrates.
In vitro research shows that goji berry tincture and juice inhibit CYP2C9 enzymes. Additionally, multiple case reports suggest that goji berry concentrated tea and juice inhibit the metabolism of warfarin, a CYP2C9 substrate. Concomitant use with goji may decrease metabolism and increase levels of CYP2C9 substrates.

Likelihood Possible Evidence D
Cytochrome P450 2D6 (Cyp2D6) Substrates

Theoretically, goji berry might inhibit CYP2D6 and reduce metabolism of CYP2D6 substrates.
In vitro research shows that goji berry juice inhibits CYP2D6 enzymes. Concomitant use with goji may decrease metabolism and increase levels of CYP2D6 substrates. However, this has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, goji berry might inhibit CYP3A4 and reduce metabolism of CYP3A4 substrates.
In vitro research shows that goji berry juice inhibits CYP3A4 enzymes. Concomitant use with goji may decrease metabolism and increase levels of CYP3A4 substrates. However, this has not been reported in humans.

Likelihood Possible Evidence D
Flecainide (Tambocor)

Theoretically, goji berry might increase the levels and clinical effects of flecainide.
In one case report, a 75-year-old patient stable on flecainide and warfarin presented to the emergency room with fainting and pleomorphic arrhythmia caused by flecainide toxicity. Flecainide toxicity was attributed to drinking 1-2 glasses of concentrated goji tea daily for 2 weeks. Theoretically, goji may have inhibited the cytochrome P450 2D6 (CYP2D6) metabolism of flecainide.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, concomitant use of goji fruit polysaccharides or goji root bark with antidiabetes drugs might have additive effects.
Animal and in vitro research show that goji root bark and fruit polysaccharides might have hypoglycemic effects. However, clinical research has only shown that taking goji fruit polysaccharides with or without antidiabetes drugs modestly reduces postprandial glucose when compared with control, with no reports of hypoglycemia.

Chinese Peony Root Extract7 drug types · 811 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, combining peony with anticoagulant or antiplatelet drugs might increase the risk of bleeding.
In vitro research suggests that peony might have antiplatelet, anticoagulant, and antithrombotic effects.

Likelihood Possible Evidence D
Clozapine (Clozaril)

Theoretically, peony might increase the levels and clinical effects of clozapine.
In vitro research shows that peony suppresses the metabolism of clozapine via weak-to-moderate inhibitory effects on cytochromes P450 (CYP) 1A2 and CYP3A4. This effect has not been reported in humans.

Likelihood Possible Evidence D
Contraceptive Drugs

Theoretically, peony might interfere with contraceptive drugs due to competition for estrogen receptors.
In vitro and animal research shows that peony extract has estrogenic activity. Concomitant use might also increase the risk for estrogen-related adverse effects.

Theoretically, use of peony may increase the levels and clinical effects of drugs metabolized by CYP1A2.
In vitro research shows that peony suppresses the metabolism of clozapine via weak-to-moderate inhibitory effects on CYP1A2 and CYP3A4. This effect has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, use of peony may increase the levels and clinical effects of drugs metabolized by CYP3A4.
In vitro research shows that peony suppresses the metabolism of clozapine via weak-to-moderate inhibitory effects on CYP1A2 and CYP3A4. This effect has not been reported in humans.

Likelihood Possible Evidence D
Estrogens

Theoretically, concomitant use of large amounts of peony might interfere with hormone replacement therapy and/or increase the risk for estrogen-related adverse effects.
In vitro and animal research shows that peony extract has estrogenic activity. Theoretically, peony might compete for estrogen receptors and/or cause additive estrogenic effects.

Likelihood Possible Evidence D
Phenytoin (Dilantin)

Theoretically, peony might reduce the levels and clinical effects of phenytoin.
Animal research shows that taking peony root reduces levels of phenytoin. Some researchers suggest that peony root might affect cytochrome P450 (CYP) 2C9, which metabolizes phenytoin. However, preliminary research in humans shows that peony root does not alter levels of losartan (Cozaar), which is also metabolized by CYP2C9.

Dong quai may increase the risk of bleeding when used with warfarin.
Case reports suggest that concomitant use of dong quai with warfarin can increase the anticoagulant effects of warfarin and increase the risk of bleeding. In one case, after 4 weeks of taking dong quai 565 mg once or twice daily, the international normalized ratio (INR) increased to 4.9. The INR normalized 4 weeks after discontinuation of dong quai.

Likelihood Probable Evidence D
Anticoagulant/Antiplatelet Drugs

Theoretically, dong quai may increase the risk of bleeding when used with anticoagulant or antiplatelet drugs; however, research is conflicting.
Animal studies suggest that dong quai has antithrombin activity and inhibits platelet aggregation due to its coumarin components. Additionally, some case reports in humans suggest that dong quai can increase the anticoagulant effects of warfarin. However, clinical research in healthy adults shows that taking 1 gram of dong quai root daily for 3 weeks does not significantly inhibit platelet aggregation or cause bleeding. Until more is known, use dong quai with caution in patients taking antiplatelet/anticoagulant drugs.

Likelihood Possible Evidence D
Estrogens

Theoretically, dong quai may reduce the effects of estrogens.
Dong quai has estrogenic effects. Theoretically, concomitant use of large amounts of dong quai might interfere with hormone replacement therapy due to competition for estrogen receptors.

Diuretic Drugs

Theoretically, asparagus racemosus root might increase diuresis and electrolyte loss when used with diuretic drugs.
Animal studies show that asparagus racemosus root has diuretic effects when used in high doses. This effect has not been reported in humans.

Likelihood Possible Evidence D
Lithium

Theoretically, Asparagus racemosus root could reduce excretion and increase levels of lithium.
Animal research suggests that Asparagus racemosus root has diuretic properties when used in high doses. Therefore, it might reduce excretion and increase levels of lithium. The dose of lithium might need to be decreased.

Fertile Garden by Health Concerns: Common Questions

Does Fertile Garden by Health Concerns interact with any medications?
Yes. Based on its ingredients, Fertile Garden has a known interaction with 1,609 medications, including 2 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Fertile Garden contains 13 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is 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.
Can I take this while pregnant or breastfeeding?
No. Multiple ingredients — Licorice, Dong Quai, Ashwagandha, Chinese Dodder, Goji, Chinese Peony, Shatavari, and Poria — all advise against use during pregnancy or breastfeeding due to limited safety data or traditional concerns about miscarriage or uterine effects. Talk to your doctor or pharmacist before considering any herbal supplement during pregnancy or lactation.
Does Licorice Root Extract in this product actually work?
Licorice Root Extract is possibly effective for canker sores and atopic dermatitis (eczema), but the evidence isn't strong. For other uses like Addison disease or asthma, we don't have enough reliable evidence to rate it.
What's Ashwagandha supposed to do?
Ashwagandha Root Extract is possibly effective for insomnia, anxiety, stress, and generalized anxiety disorder. It's generally well tolerated short-term in healthy adults, though quality and long-term safety data are limited.
What are the most common side effects I might experience?
The most common side effects across the ingredients are gastrointestinal — nausea, vomiting, diarrhea, and abdominal discomfort. Licorice can also cause headache; Ashwagandha may cause drowsiness; and Dong Quai may cause burping and flatulence. Most of these occur at higher doses or with long-term use.
Is this product safe if I don't take any medications?
If you're not taking medications, the main safety concerns are the pregnancy and breastfeeding restrictions, and the fact that several ingredients — Licorice, Ashwagandha, Goji, Peony, and Poria — have limited long-term human safety data. Use as directed and watch for gastrointestinal side effects. If you have any chronic health conditions, talk to your pharmacist first.
Does this product have any fillers?
Yes. The inactive ingredients are hypromellose (a capsule material) and rice.
