HelloPharmacist Scorecard of Linking Decoction Teapills by Plum Flower
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
Linking Decoction Teapills is a 6-ingredient herbal capsule formula built around extracts of dong quai root, rehmannia root, goji fruit, ophiopogon tuber, glehnia root, and melia fruit, combined in a proprietary blend. The inactive ingredients are magnesium silicate, activated carbon, dextrin, and china wax — these are the capsule materials and binders that hold the formula together.
Does it work?
Moderate evidence
The evidence supporting these ingredients is limited. Dong quai carries insufficient reliable evidence to rate for iron deficiency anemia, osteoporosis, heart disease, migraines, and eczema.
Rehmannia is rated possibly effective for chronic kidney disease but has insufficient evidence for aplastic anemia, atopic disease, osteoporosis, diabetes, and diabetic kidney disease. Goji shows insufficient evidence across cardiovascular disease, high blood pressure, obesity, sunburn, and quality of life.
No effectiveness claims are established in the data we hold for this formula overall.
How safe is it?
Well-documented data
Dong quai is generally well tolerated by mouth, though burping and flatulence are the most common side effects. It can increase bleeding risk and cause skin sensitivity to sunlight, so use with care if you're already on a blood thinner or spend extended time in the sun.
Rehmannia has limited human safety data and quality varies between products. Both dong quai and rehmannia are advised against in pregnancy due to the risk of uterine stimulation and effects on bleeding.
Goji is generally safe as a food but has less safety data in concentrated supplement form; it's been linked to rare cases of allergic reactions (including angioedema and anaphylaxis) and, in one instance, hepatitis. Neither dong quai nor goji have adequate safety information for breastfeeding, so both are best avoided while nursing.
Meds to double-check
Major interaction found
Check your medications if you take warfarin or any other blood thinner (anticoagulant or antiplatelet drug) — dong quai and goji carry Major and Moderate risks of increased bleeding. Also double-check if you're on blood pressure medication, diabetes medication, flecainide, or any medication metabolized by your liver's CYP450 enzymes — goji especially may affect how your body processes these drugs.
The bottom line
Scorecard at a glanceFormula with limited ingredient disclosure with some supporting evidence behind its ingredients' uses. Major medication interactions have been identified, and safety information is well characterized.
This formula is built on traditional Chinese herbs with very limited modern evidence of effectiveness. The real concern is interaction risk — if you take warfarin, any blood thinner, blood pressure medication, diabetes medication, or the heart drug flecainide, you need to check this product against your exact medications before starting.
Talk to your pharmacist or doctor; pregnancy and breastfeeding are reasons to avoid it.

Linking Decoction Teapills by Plum Flower Drug Interactions
HelloPharmacist Interaction Report
Linking Decoction Teapills by Plum Flower contains several ingredients that interact with medications, and the most serious concern is bleeding risk.
Dong quai (Angelica sinensis) and goji (Lycium barbarum) both carry Major-severity interactions with warfarin (Coumadin), a blood thinner. Case reports show that both can increase warfarin's anticoagulant effects and raise bleeding risk — dong quai has been documented raising INR values after just 4 weeks of use, and goji has at least 5 case reports of increased INR in patients on stable warfarin doses.
Read the full breakdown — every affected drug type, severity by severity
Beyond warfarin, goji affects how your liver metabolizes several drug types. It can theoretically reduce the breakdown of CYP3A4, CYP2C9, CYP2C19, and CYP2D6 substrates — a broad category that includes many common medications — though human cases remain rare.
Additionally, both dong quai and rehmannia (Rehmannia glutinosa) carry Moderate-severity interactions with blood thinners other than warfarin and antiplatelet drugs. Rehmannia may lower your blood pressure and blood sugar when combined with medications for those conditions.
Goji also theoretically may add to the effects of blood pressure medications and flecainide (Tambocor), a heart rhythm drug.
We couldn't check three other ingredients in this product — ophiopogon, glehnia, and melia — because no interaction data are held for them. Altogether, these interactions span 1,050 individual medications.

For each ingredient in Linking Decoction Teapills 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.
Lycium barbarum Fruit Extract
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).
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.
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.
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.
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.
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.
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.
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.
Rehmannia glutinosa Root Extract
Antidiabetes Drugs
Theoretically, rehmannia might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Animal research shows that rehmannia may have hypoglycemic effects.
Antihypertensive Drugs
Theoretically, rehmannia might increase the risk of hypotension when taken with antihypertensive drugs.
Animal research shows that rehmannia may have hypotensive effects. Laboratory research shows that formulations of dried and processed rehmannia root inhibit angiotensin-converting enzyme (ACE).
Angelica sinensis Root Extract
Warfarin (Coumadin)
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.
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.
