HelloPharmacist Scorecard of RST-C by Pure Herbs
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
RST-C contains eight active ingredients in a proprietary blend. The standouts are fo-ti root extract (used traditionally for vitality and hair health), chickweed aerial parts extract (historically used for skin and weight support), arrowroot root extract (traditionally used for digestive comfort), and calendula flower extract (known for skin support).
The blend also includes two whole algae extracts—kelp and bladderwrack—plus Irish moss extract and white mustard seed extract. There are no other inactive ingredients listed.
Does it work?
Not established
The evidence supporting most ingredients in this blend is not established in our data. Chickweed, arrowroot, calendula, and fo-ti all carry ratings of insufficient reliable evidence for their traditional uses—meaning the research to confirm they work for these purposes isn't solid yet.
White mustard seed has no effectiveness ratings on file. The other ingredients lack effectiveness data we can review.
This doesn't mean they don't work; it means the clinical evidence we hold doesn't establish it.
How safe is it?
Well-documented data
Fo-ti is the safety concern here. It has been linked to liver injury in around 450 documented cases, ranging from mild hepatitis to cirrhosis.
Liver damage occurred across a wide range of doses and durations, so there's no safe threshold we can identify. It commonly causes abdominal pain, diarrhea, nausea, and vomiting—especially with raw or unprocessed forms.
Fo-ti is rated possibly unsafe in pregnancy and lactation, and chickweed is rated best avoided in both. Calendula is rated likely unsafe in pregnancy.
Arrowroot and white mustard seed lack strong safety data for pregnancy and concentrated use. Calendula can cause allergic reactions, especially in people sensitive to ragweed or related plants.
White mustard seed can cause allergic skin reactions and stomach irritation. Chickweed is generally considered low-risk for short-term use, but high-quality safety data are limited.
Meds to double-check
Moderate interaction found
If you take warfarin or any other blood thinner (anticoagulant), do not start this product without checking with your pharmacist or doctor first—fo-ti carries Moderate risk of increased bleeding. Also double-check before use if you take heart medications (digoxin), anti-inflammatory drugs (sulindac), drugs metabolized by liver enzymes (CYP2C8 or CYP2B6 substrates), diuretics, stimulant laxatives, or CNS depressants (sedating medications).
Altogether, these interactions span 1,312 individual medications.
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.
This product is built on traditional herbs with limited clinical proof they work. The real concern is fo-ti, which carries documented liver injury risk and interacts with blood thinners and several other drug classes.
If you take any prescription medications—especially warfarin or other anticoagulants, heart drugs, diuretics, or medications metabolized by your liver—talk to your pharmacist or doctor before starting. Pregnant or breastfeeding?
Skip this one; several ingredients lack adequate safety data or are advised against.

RST-C by Pure Herbs Drug Interactions
HelloPharmacist Interaction Report
Pure Herbs RST-C is a liquid blend of eight ingredients, and one of them—fo-ti root extract—carries documented interactions with a number of medications.
The most serious concern is blood thinners (anticoagulants), particularly warfarin. Fo-ti has been linked to cases of acute liver failure that can affect how your body makes clotting factors; one documented case involved a patient stable on warfarin who developed severe liver inflammation and a dangerously elevated clotting measure after 90 days of fo-ti use.
Diarrhea from fo-ti can also amplify warfarin's blood-thinning effect and raise bleeding risk.
Read the full breakdown — every affected drug type, severity by severity
Fo-ti also interacts with several other drug types. It may increase levels of drugs broken down by certain liver enzymes (CYP2C8 and CYP2B6 substrates), affect the heart drug digoxin and raise potassium loss, interfere with the anti-inflammatory sulindac, and compound fluid and electrolyte loss when combined with stimulant laxatives or diuretic drugs—all rated Moderate severity.
Additionally, calendula flower extract in this product carries a Minor interaction with CNS depressants (sedating medications), though human reports of this effect are lacking.
Chickweed, arrowroot, white mustard seed, and two algae ingredients (kelp and bladderwrack) have no known interactions documented. We could not check kelp, bladderwrack, or Irish moss because interaction data for these ingredients are not on file.
Altogether, these interactions span 1,312 individual medications.
Before you start this product, run your exact medications through the search tool on this page—especially if you take any blood thinners, heart medications, diuretics, or drugs metabolized by your liver.

For each ingredient in RST-C 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.
Fo-Ti Root Extract
Anticoagulant/Antiplatelet Drugs
Fo-ti has been linked to cases of acute liver failure which can decrease clotting factor production and increase the effects of anticoagulants. In one case, a patient who had been stable on warfarin presented with acute hepatitis and an INR elevated to 14.98. The patient had been taking fo-ti for 90 days prior to admission. Discontinuation of warfarin and fo-ti lead to a decrease in the INR and full recovery. Theoretically, concomitant use of fo-ti with anticoagulant or antiplatelet drugs may increase the risk of bleeding in some patients. Until more is known, monitor patients taking fo-ti and drugs that affect bleeding.
Some of these drugs include aspirin, clopidogrel (Plavix), dalteparin (Fragmin), dipyridamole (Persantine), enoxaparin (Lovenox), heparin, ticlopidine (Ticlid), warfarin (Coumadin), and others.
Antidiabetes Drugs
Theoretically, fo-ti might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Fo-ti reportedly has hypoglycemic effects.
Contraceptive Drugs
Theoretically, taking large amounts of fo-ti might interfere with contraceptive drugs due to competition for estrogen receptors.
In vitro research suggests that fo-ti extract has estrogenic activity.
Cytochrome P450 1A2 (Cyp1A2) Substrates
Theoretically, fo-ti might increase or decrease the levels and clinical effects of drugs metabolized by CYP1A2.
In vitro research suggests that fo-ti might inhibit CYP1A2. Additionally, in vitro research suggests that the degree of CYP1A2 inhibition depends on the type of fo-ti extract (i.e., the raw plant leads to greater inhibition than extensively processed extracts). However, in an animal study, an aqueous extract of fo-ti inhibited CYP1A2 while an alcoholic extract of fo-ti induced CYP1A2. Induction or inhibition of CYP1A2 by fo-ti has not been reported in humans.
Cytochrome P450 2B6 (Cyp2B6) Substrates
Theoretically, fo-ti might increase the levels and clinical effects of drugs metabolized by CYP2B6.
Animal research suggests that fo-ti might inhibit CYP2B6. One in vitro study suggests that the degree of CYP2B6 inhibition may depend on the type of fo-ti extract (i.e., the raw plant leads to greater inhibition than extensively processed extracts). However, this interaction has not been reported in humans.
Cytochrome P450 2C19 (Cyp2C19) Substrates
Theoretically, fo-ti may increase the levels and clinical effects of drugs metabolized by CYP2C19.
Animal and in vitro research suggests that fo-ti may inhibit CYP2C19. An in vitro study suggests that the degree of CYP2C19 inhibition may depend on the type of fo-ti extract (i.e., the raw plant leads to greater inhibition than extensively processed extracts). However, this interaction has not been reported in humans.
Cytochrome P450 2C8 (Cyp2C8) Substrates
Theoretically, fo-ti might increase the levels and clinical effects of drugs metabolized by CYP2C8.
In vitro research suggests that fo-ti might inhibit CYP2C8. However, this interaction has not been reported in humans.
Cytochrome P450 2C9 (Cyp2C9) Substrates
Theoretically, fo-ti may increase the levels and clinical effects of drugs metabolized by CYP2C9.
Animal and in vitro research suggests that fo-ti may inhibit CYP2C9. However, this interaction has not been reported in humans.
Cytochrome P450 2D6 (Cyp2D6) Substrates
Theoretically, fo-ti may increase the levels and clinical effects of drugs metabolized by CYP2D6.
Animal research suggests that fo-ti might inhibit CYP2D6. Additionally, an in vitro study suggests that the degree of CYP2D6 inhibition may depend on the type of fo-ti extract (i.e., the raw plant leads to greater inhibition than extensively processed extracts). However, this interaction has not been reported in humans.
Cytochrome P450 3A4 (Cyp3A4) Substrates
Theoretically, fo-ti might increase the levels and clinical effects of drugs metabolized by CYP3A4.
In vitro research suggests that fo-ti might inhibit CYP3A4. One in vitro study suggests that the degree of CYP3A4 inhibition may depend on the type of fo-ti extract (i.e., the raw plant leads to greater inhibition than extensively processed extracts). However, this evidence conflicts with animal research suggesting that fo-ti does not inhibit CYP3A4. This interaction has not been reported in humans.
Digoxin (Lanoxin)
Theoretically, fo-ti, particularly raw fo-ti root, might increase the risk of hypokalemia and cardiotoxicity when taken with digoxin.
Raw fo-ti root contains anthraquinone derivatives, which might have stimulant laxative effects. In vitro research shows that fermented and processed fo-ti root have reduced laxative effects compared with raw fo-ti root.
Diuretic Drugs
Theoretically, fo-ti, particularly raw fo-ti root, might increase the risk of hypokalemia when taken with diuretic drugs.
Raw fo-ti root contains anthraquinone derivatives, which might have stimulant laxative effects and compound diuretic-induced potassium loss. In vitro research shows that fermented and processed fo-ti root have reduced laxative effects compared with raw fo-ti root.
Estrogens
Theoretically, taking large amounts of fo-ti might interfere with hormone replacement therapy through competition for estrogen receptors.
In vitro research suggests that fo-ti extract has estrogenic activity.
Hepatotoxic Drugs
Theoretically, fo-ti might increase the risk of liver damage when taken with hepatotoxic drugs.
Fo-ti has been linked to liver damage in many reports.
Stimulant Laxatives
Theoretically, fo-ti, particularly raw fo-ti root, might increase the risk of fluid and electrolyte depletion when taken with stimulant laxatives.
Raw fo-ti root contains anthraquinone derivatives, which might have stimulant laxative effects. However, in vitro research shows that fermented and processed fo-ti root have reduced laxative effects compared with raw fo-ti root.
Sulindac (Clinoril)
Theoretically, fo-ti might increase or decrease the levels and clinical effects of sulindac.
Animal research suggests that the type of fo-ti extract might affect the levels of sulindac differently; the raw plant may increase levels, but processed parts may decrease levels. Induction or inhibition of CYP1A2 by fo-ti has not been reported in humans.
Warfarin (Coumadin)
Theoretically, fo-ti might increase the effects and adverse effects of warfarin.
Fo-ti may have stimulant laxative effects and cause diarrhea, especially when the raw or unprocessed fo-ti root is used. Diarrhea can increase the effects of warfarin, increase international normalized ratio (INR), and increase the risk of bleeding. Also, fo-ti has been linked to cases of acute liver failure which can decrease clotting factor production and increase the effects of warfarin. In one case, a patient who had been stable on warfarin presented with acute hepatitis and an INR elevated to 14.98. The patient had been taking fo-ti for 90 days prior to admission. Discontinuation of warfarin and fo-ti lead to a decrease in the INR and full recovery.
Kelp Whole Algae Extract
Amiodarone (Cordarone)
Theoretically, combining Fucus vesiculosus with amiodarone might cause excessively high iodine levels.
Fucus vesiculosus contains high concentrations of iodine. Amiodarone contains 37.3% iodine and can increase iodine levels. Concomitant use might increase the risk of having excessive iodine levels and adversely affecting thyroid function. Monitor thyroid function.
Antithyroid Drugs
Due to its iodine content, Fucus vesiculosus might alter the effects of antithyroid drugs.
Fucus vesiculosus contains high concentrations of iodine. Iodine in high doses has been reported to cause both hyperthyroidism and hypothyroidism, depending on the individual's past medical history. Taking Fucus vesiculosus while using antithyroid drugs could alter the effects of the antithyroid drugs.
Lithium
Concomitant use of Fucus vesiculosus and lithium has resulted in hyperthyroidism.
There is a case of hyperthyroidism occurring in a patient taking Fucus vesiculosus and lithium. Monitor thyroid hormones closely in patients taking lithium and Fucus vesiculosus concomitantly.
Thyroid Hormone
Due to its iodine content, Fucus vesiculosus might alter the effects of thyroid hormone.
Fucus vesiculosus contains high concentrations of iodine. Iodine in high doses has been reported to cause both hyperthyroidism and hypothyroidism, depending on the individual's past medical history. Taking Fucus vesiculosus while using thyroid hormone could alter the effects of thyroid hormone.
Anticoagulant/Antiplatelet Drugs
Theoretically, taking Fucus vesiculosus with antiplatelet or anticoagulant drugs might increase the risk of bruising and bleeding.
In vitro evidence suggests that a constituent of Fucus vesiculosus, known as fucoidan, has anticoagulant effects. However, in clinical research, fucoidan does not seem to have significant anticoagulant activity when taken orally, possibly due to poor absorption.
Cytochrome P450 2C8 (Cyp2C8) Substrates
Theoretically, concomitant use of Fucus vesiculosus with CYP2C8 substrates might increase the risk for adverse effects.
In vitro research shows that fucoidan, a constituent of Fucus vesiculosus, inhibits CYP2C8. This interaction has not been reported in humans.
Cytochrome P450 2C9 (Cyp2C9) Substrates
Theoretically, concomitant use of Fucus vesiculosus with CYP2C9 substrates might increase the risk for adverse effects.
In vitro research shows that fucoidan, a constituent of Fucus vesiculosus, inhibits CYP2C9. This interaction has not been reported in humans.
Cytochrome P450 2D6 (Cyp2D6) Substrates
Theoretically, concomitant use of Fucus vesiculosus with CYP2D6 substrates might alter the effects of these substrates.
In vitro research shows that fucoidan, a constituent of Fucus vesiculosus, both inhibits and induces CYP2D6. This interaction has not been reported in humans.
Cytochrome P450 3A4 (Cyp3A4) Substrates
Theoretically, concomitant use of Fucus vesiculosus with CYP3A4 substrates might increase the risk for adverse effects.
In vitro research shows that fucoidan, a constituent of Fucus vesiculosus, inhibits CYP3A4. This interaction has not been reported in humans.
Calendula Flower Extract
Cns Depressants
Theoretically, calendula might have additive effects when used with CNS depressants, although this appears to be unlikely.
Although some animal research has suggested that a saponoside constituent in calendula may have sedative effects, calendula has been used for over 30 years without reports of sedation in humans.
Irish Moss Extract
Amiodarone (Cordarone)
Theoretically, combining sea moss with amiodarone might cause excessively high iodine levels.
Amiodarone contains 37.3% iodine and can increase iodine levels. Concomitant use with sea moss, which contains approximately 4-7 mcg of iodine per gram, might increase the risk of adverse effects from iodine, including altered thyroid function.
Antithyroid Drugs
Due to its iodine content, sea moss might alter the effects of antithyroid drugs.
Sea moss contains approximately 4-7 mcg of iodine per gram. Iodine in high doses has been reported to cause both hyperthyroidism and hypothyroidism, depending on the individual's past medical history. Taking sea moss could theoretically alter the effects of antithyroid drugs.
Thyroid Hormone
Due to its iodine content, sea moss might alter the effects of thyroid hormone.
Sea moss contains approximately 4-7 mcg of iodine per gram. Iodine in high doses has been reported to cause both hyperthyroidism and hypothyroidism, depending on the individual's past medical history. Taking sea moss could theoretically alter the effects of thyroid hormone.
