HelloPharmacist Scorecard of Chinese Skullcap 400 mg by Swanson
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
Full disclosure
This product contains one active ingredient: Chinese Skullcap Root Concentrate (Baikal skullcap), at 400 mg per capsule. The inactive ingredients are rice bran, gelatin, maltodextrin, silica, and calcium palmitate.
Does it work?
Not established
The evidence for Chinese Skullcap's effectiveness isn't established in the data we hold. Our monograph rates it as having insufficient reliable evidence for hay fever, anxiety, atherosclerosis, ADHD, prostate cancer, and headache.
That means human studies don't yet support its use for these conditions — not that it doesn't work, but that we simply don't have solid evidence either way.
How safe is it?
Well-documented data
Taken by mouth, Baikal skullcap is generally well tolerated. The most common side effects are abdominal pain, constipation, diarrhea, nausea, vomiting, skin redness, and itching.
Serious side effects are rare but have been reported: liver injury and a type of lung inflammation (hypersensitivity pneumonitis) appeared in studies of a combination product containing Baikal skullcap extract. Human safety data are limited, and product quality varies.
The safety data advises against use during pregnancy and while breastfeeding because there isn't enough information to know whether it's safe for you or your baby.
Meds to double-check
Moderate interaction found
Before taking this product, double-check your medications against these types: blood pressure drugs, blood thinners or antiplatelet drugs, diabetes medications, hormone replacement therapy, lithium, antithyroid drugs, and any drugs broken down by liver enzymes CYP2C19 or CYP1A2. All of these carry moderate-severity interaction risks with Baikal skullcap.
The bottom line
Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.
Chinese Skullcap might be worth considering if you're interested in traditional herbal support, but it comes with real drug interactions you need to check first. If you take blood pressure pills, diabetes medications, blood thinners, mood stabilizers, hormone therapy, or drugs cleared by your liver, talk it over with your doctor or pharmacist before starting.
Pregnant or nursing? Skip it — there's not enough safety data.

Chinese Skullcap 400 mg by Swanson Drug Interactions
HelloPharmacist Interaction Report
Chinese Skullcap 400 mg by Swanson contains Baikal skullcap root, which has documented interactions with multiple medication types.
The most serious concerns are moderate-severity interactions across eight drug categories.
Read the full breakdown — every affected drug type, severity by severity
Baikal skullcap may lower blood pressure, so it could add to the effect of blood pressure medications (antihypertensives) and raise the risk of blood pressure dropping too far. It may also slow how your body clears certain medications.
Lab evidence suggests it inhibits two liver enzymes — CYP2C19 and CYP1A2 — which could raise levels of drugs that depend on those enzymes to break down; this hasn't been seen in human studies yet, but it's a theoretical concern.
Additionally, this ingredient may increase bleeding risk when paired with blood thinners or antiplatelet drugs (like aspirin or warfarin), may enhance the blood-sugar-lowering effect of diabetes medications, may interfere with hormone replacement therapy, and may interact with lithium (a mood stabilizer used for bipolar disorder) by raising its levels in your blood. There's also a theoretical concern with antithyroid drugs.
Altogehter, these interactions span 946 individual medications. Use the medication checker on this page to verify your exact drugs before starting.

For each ingredient in Chinese Skullcap 400 mg with known interactions, here are the types of medications it can affect. Open any type for the detail — or search your exact drug in the checker above.
Chinese Skullcap Root Concentrate
Anticoagulant/Antiplatelet Drugs
Theoretically, Baikal skullcap might increase the risk of bleeding when used concomitantly with anticoagulant and antiplatelet drugs.
Preliminary clinical research suggests that taking capsules containing a combination of astragalus, goldthread, and Baikal skullcap daily for 4 weeks inhibits platelet aggregation; the effect seems to be similar to that of aspirin 50 mg daily. It is unclear if this effect is due to Baikal skullcap, other ingredients, or the combination.
Antidiabetes Drugs
Theoretically, concomitant use of Baikal skullcap with antidiabetes drugs might enhance blood glucose lowering effects.
Baicalein, a constituent of Baikal skullcap, has alpha-glucosidase inhibitory activity in vitro. Animal research also suggests that Baikal skullcap enhances the antidiabetic effects of metformin. However, in a small human study, taking Baikal skullcap extract did not enhance the antidiabetic effects of metformin, although it did modestly lower glucose levels during an oral glucose tolerance test (OGTT). Until more is known, use cautiously.
Antihypertensive Drugs
Theoretically, concomitant use of Baikal skullcap with antihypertensive drugs might have additive effects and increase the risk of hypotension.
Animal research suggests that baicalein, a constituent of Baikal skullcap, might lower blood pressure.
Antithyroid Drugs
Theoretically, concomitant use of Baikal skullcap and antithyroid drugs may result in additive activity and increase the risk of hypothyroidism.
In an animal hyperthyroid model, Baikal skullcap improved levels of triiodothyronine (T3), thyroxine (T4), and thyroid stimulating hormone (TSH). The clinical significance of this effect is unclear.
Cytochrome P450 1A2 (Cyp1A2) Substrates
Theoretically, Baikal skullcap may increase levels of drugs metabolized by CYP1A2 enzymes.
In vitro evidence suggests that constituents of Baikal skullcap inhibit the activity of CYP1A2. This effect has not been reported in humans.
Cytochrome P450 2C19 (Cyp2C19) Substrates
Theoretically, Baikal skullcap might increase levels of drugs metabolized by CYP2C19 enzymes.
In vitro evidence suggest that wogonin, a constituent of Baikal skullcap, modestly inhibits the activity of CYP2C19 enzymes. This effect has not been reported in humans.
Estrogens
Theoretically, concomitant use of large amounts of Baikal skullcap might interfere with hormone replacement therapy, due to competition for estrogen receptors.
In vitro evidence suggests that Baikal skullcap has estrogenic activity.
Lithium
Theoretically, Baikal skullcap might reduce lithium excretion and increase serum levels of lithium.
Baikal skullcap is thought to have diuretic properties, which may reduce lithium excretion. The dose of lithium might need to be decreased.
Alcohol (Ethanol)
Theoretically, Baikal skullcap might potentiate the sedative effects of alcohol.
In vitro and animal research suggests that Baikal skullcap binds to GABA-A receptors and causes sedation. Theoretically, Baikal skullcap might potentiate the sedative effects of alcohol. Preliminary clinical research has not identified clinically relevant sedation after use of Baikal skullcap; however, a thorough evaluation of safety outcomes has not been conducted.
Cns Depressants
Theoretically, Baikal skullcap might cause additive therapeutic and adverse effects when used concomitantly with drugs with sedative properties.
In vitro and animal research suggests that Baikal skullcap binds to GABA-A receptors and causes sedation. Theoretically, Baikal skullcap might cause additive therapeutic and adverse effects when used concomitantly with drugs with sedative properties. Preliminary clinical research has not identified clinically relevant sedation after use of Baikal skullcap; however, a thorough evaluation of safety outcomes has not been conducted.
Organic Anion-Transporting Polypeptide Substrates (Oatp)
Theoretically, Baikal skullcap might alter the levels and clinical effects of OATP substrates.
Some pharmacokinetic research shows that baicalin, a constituent of Baikal skullcap, can decrease plasma levels of rosuvastatin. The mechanism is thought to involve stimulation of the activity of the organic anion-transporting polypeptide 1B1 (OATP1B1), which transports rosuvastatin into the liver. This decreases plasma levels of the drug, but increases levels at the site of action in the liver. The degree to which rosuvastatin levels are affected depends on the OATP1B1 haplotype of the individual. Baikal skullcap might also affect other OATP1B1 substrates.
P-Glycoprotein Substrates
Theoretically, Baikal skullcap might increase levels of drugs transported by P-glycoprotein.
In vitro and animal research suggests that baicalein, oroxylin A, and wogonin, constituents of Baikal skullcap, can inhibit P-glycoprotein. This effect has not been reported in humans.
