• Common cold. Oral andrographis, taken alone or as part of a specific combination product (Kan Jang, Swedish Herbal Institute) also containing eleuthero, seems to improve symptoms of the common cold. It is unclear if oral andrographis is beneficial for preventing the common cold. Details: Most clinical research shows that taking andrographis alone or as part of a combination herbal supplement improves cold symptoms (2744,2773,2774,5784,10795,12380,12381,98222). Taking a specific combination product (Kan Jang, Swedish Herbal Institute) containing andrographis extract, standardized to andrographolides 4-5.6 mg, and eleuthero three times daily seems to improve symptoms of the common cold when started within 72 hours of symptom onset. Some symptoms can improve after 2 days of treatment, but it typically takes 4-5 days of treatment for maximal symptom relief (2744,2773,2774,5784,10795,12380). This combination also seems to relieve cold symptoms better than echinacea or placebo in children (12381). Other clinical research shows that taking a specific andrographis extract (KalmCold) 200 mg daily for 5 days reduces cold symptoms by approximately two-fold and increases the number of patients who respond to treatment when compared with placebo (31222). Preliminary clinical research shows that taking andrographis (Kan Jang, Swedish Herbal Institute) prophylactically might decrease the risk of developing a cold by about 50% after 2 months of continuous treatment (2772); however, more evidence is needed to confirm these results.
• Osteoarthritis. Oral andrographis extract has been evaluated for the treatment of osteoarthritis, with promising results. Details: In patients with mild to moderate osteoarthritis of the knee, clinical research shows that taking a specific brand of andrographis extract (ParActin, HP Ingredients) 300 mg and 600 mg daily for 12 weeks reduces pain and stiffness by approximately 40% and 46%, respectively, compared with changes of less than 10% with placebo (101116).
• Tonsillopharyngitis. Oral andrographis has been evaluated for the management of fever and sore throat associated with tonsillopharyngitis, with promising results. Details: Some clinical research shows that andrographis 6 grams daily is comparable to acetaminophen for reducing fever and sore throat associated with tonsillopharyngitis after 3 and 7 days of treatment (2748).
• Ulcerative colitis. Oral andrographis extract has been evaluated for the management of ulcerative colitis symptoms, with promising results. Details: Some clinical research shows that taking andrographis extract 1200-1800 mg daily for 8 weeks reduces symptoms of mild to moderate ulcerative colitis, but does not affect remission rates, when compared with placebo (31231). Additional clinical research also shows that taking andrographis extract 1200 mg daily for 8 weeks is as effective as mesalamine for reducing symptoms in patients with ulcerative colitis (31223).

• Acute bronchitis. Although there has been interest in using oral andrographis for acute bronchitis, there is insufficient reliable information about the clinical effects of andrographis for this purpose.
• Cognitive impairment. Oral andrographis has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Clinical research in a small number of patients with mild cognitive impairment shows that taking a combination product (Adaptra Forte, Europharma USA) containing andrographis extract 400 mg, standardized to andrographolides 40 mg, and ashwagandha extract 150 mg twice daily for 4 weeks modestly improves some measures of concentration and sleep quality when compared with placebo (104822).
• Coronavirus disease 2019 (COVID-19). It is unclear if oral andrographis is beneficial in mild to moderate COVID-19. Details: A moderate-sized clinical study in adults with mild to moderate COVID-19 receiving standard of care conducted in India shows that taking andrographis raw plant part extract 200 mg twice daily for 14 days improves the time to clinical improvement by 2-points on the World Health Organization (WHO) scale to about 4 days compared with about 6 days in the control group (112920). However, the interpretation of this finding is limited by unbalanced groups with sicker patients in the control group. Additionally, a large observational study conducted in Thailand in unvaccinated hospitalized adults with mild COVID-19 suggests that taking andrographis, dosed as andrographolide 60 mg, three times daily for 5 days is not associated with a decrease in the risk of developing pneumonia when compared with standard of care (112919).
• Diabetes. Oral andrographis has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical trial in adults with type 2 diabetes who are taking metformin 1000 mg daily shows that taking a combination product containing andrographis and Syzygium polyanthum leaf extracts, 900 mg daily for 8 weeks, does not improve fasting blood glucose levels, glycated hemoglobin (HbA1c), blood pressure, or blood lipid levels when compared with placebo (101117).
• Familial Mediterranean fever. Oral andrographis has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in children 3-15 years of age shows that taking a combination product (ImmunoGuard, Inspired Nutritionals) containing andrographis 16 mg, eleuthero, schisandra, and licorice daily for 1 month reduces the duration, frequency, and severity of attacks of familial Mediterranean fever (12382).
• Hypertriglyceridemia. It is unclear if oral andrographis is beneficial in patients with hypertriglyceridemia. Details: A small clinical study in adults with hypertriglyceridemia shows that taking andrographis, standardized to contain andrographolide 119.64-120.36 mg, by mouth daily for 8 weeks decreases triglycerides by 42 mg/dL, demonstrating comparable effects to gemfibrozil. However, compared to baseline, total cholesterol was increased by 15 mg/dL and low-density lipoprotein (LDL) cholesterol was increased by 21 mg/dL, suggesting that the benefits of lower triglycerides may be offset by elevations in other lipid levels. Taking a lower daily dose of andrographis, standardized to contain andrographolide 71.64-72.36 mg, does not seem to affect lipid levels (91839).
• Impaired glucose tolerance (prediabetes). It is unclear if oral andrographis is beneficial in patients with prediabetes. Details: A small crossover clinical study in adults with prediabetes conducted in Indonesia shows that taking andrographis 550 mg for 14 days increases glucagon-like peptide 1 (GLP-1) levels but does not statistically improve measures of insulin resistance (i.e., fasting insulin, fasting glucose, 2-hour postprandial glucose, 2-hour postprandial insulin, homeostatic model assessment for insulin resistance [HOMA-IR]) when compared with placebo (112918). However, it is unclear whether this improvement is clinically significant. In addition, the frequency of andrographis dosing is unclear.
• Influenza. Oral andrographis has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research shows that patients with influenza who take a specific product (Kan Jang, Swedish Herbal Institute) containing andrographis extract, standardized to andrographolides 4-5.6 mg, and eleuthero three times daily for 3-5 days have more rapid symptom relief when compared with patients taking amantadine. Taking this combination product also seems to reduce the risk of post-influenza complications such as rhinosinusitis or bronchitis when compared with amantadine (10441).
• Migraine headache. Oral andrographis has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Research has evaluated a combination product (Vivinor, Brain Therapeutics; Partena, FB Health) containing andrographis 100 mg, magnesium 281 mg, riboflavin 5 mg, feverfew 150 mg, and coenzyme Q10 20 mg. A nonblinded, clinical study in patients with episodic migraines shows that taking 1-2 tablets of this product daily for 3 months decreases monthly average migraine days, migraine severity, and the number of days an acute migraine medication is used when compared with baseline. In the third month of treatment, 57% of patients had at least a 50% reduction in average migraine days (107473). The validity of this study is limited by the lack of randomization and placebo-control; additionally, it is unclear if any effects are due to andrographis, the other ingredients, or the combination.
• Multiple sclerosis (MS). It is unclear if oral andrographis is beneficial in patients with MS. Details: A small clinical study in patients with relapsing-remitting MS currently receiving interferon-beta shows that taking andrographis dried extract (Innobioscience Spa) 170 mg, standardized to contain andrographolides 85 mg, twice daily for 12 months decreases fatigue by 44%, but does not affect relapse rate or disability, when compared with placebo (91838). Another small clinical study of patients with primary or secondary, but not active, progressive MS shows that taking andrographolide, a constituent of andrographis, 140 mg twice daily for 24 months slows the progression of disability when compared with placebo (104821).
• Rheumatoid arthritis (RA). It is unclear if oral andrographis is beneficial in patients with RA. Details: Preliminary clinical research shows that taking andrographis extract 90 mg daily for 14 weeks reduces symptoms of RA when compared to baseline, but not when compared with placebo (31220).
• Rhinosinusitis. Although there has been interest in using oral andrographis for rhinosinusitis, there is insufficient reliable information about the clinical effects of andrographis for this purpose.
• Upper respiratory tract infection (URTI). Oral andrographis has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: One small clinical study in adults with uncomplicated URTI shows that a specific combination product (Kan Jang, Swedish Herbal Institute) containing andrographis 195 mg and eleuthero root 11.4 mg per capsule, taken as two capsules three times daily for 5 days, reduces the median number of sick leave days to 2 days, compared with 3 days in the placebo group. It also increases the total number of recovered patients on day 3 to 75%, compared with 55% of those taking placebo (107471). More evidence is needed to rate andrographis for these uses.

• Allergic rhinitis (hay fever). Although there has been interest in using oral Baikal skullcap for allergic rhinitis, there is insufficient reliable information about the clinical effects of Baikal skullcap for this purpose.
• Anxiety. Although there has been interest in using oral Baikal skullcap for anxiety, there is insufficient reliable information about the clinical effects of Baikal skullcap for this purpose.
• Atherosclerosis. Although there has been interest in using oral Baikal skullcap for atherosclerosis, there is insufficient reliable information about the clinical effects of Baikal skullcap for this purpose.
• Attention deficit-hyperactivity disorder (ADHD). Although there has been interest in using oral Baikal skullcap for ADHD, there is insufficient reliable information about the clinical effects of Baikal skullcap for this purpose.
• Bronchiolitis. Intravenous Baikal skullcap has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research shows that a combination of Baikal skullcap, forsythia, and honeysuckle, known as Shuang Huang Lian in traditional Chinese medicine, given intravenously, with or without antibiotics, decreases the duration of cough by about 1.5-2 days, the duration of wheezing by about 2 days, and the duration of hospitalization by about 2-3 days when compared with antibiotics alone in children with respiratory syncytial virus (RSV) infection. Baikal skullcap injection was administered as a 20 mL dose for patients under 6 months, a 40 mL dose for patients 7-36 months, or a 60 mL dose for patients older than 36 months (12613).
• Cancer. Although there has been interest in using oral Baikal skullcap for cancer, there is insufficient reliable information about the clinical effects of Baikal skullcap for this purpose.
• Diabetes. It is unclear if oral Baikal skullcap is beneficial in patients with diabetes. Details: A very small clinical trial in patients with uncontrolled diabetes taking metformin 500 mg daily shows that taking Baikal skullcap extract 3.52 grams in three divided doses daily for 8 weeks does not decrease levels of fasting glucose or insulin or improve levels of glycated hemoglobin (HbA1c) when compared with placebo. However, taking Baikal skullcap reduces blood glucose levels during an oral glucose tolerance test (OGTT) at 60 minutes, but not 120 minutes, when compared with placebo (101738). This study may have been inadequately powered to detect a difference between groups.
• Epilepsy. Although there has been interest in using oral Baikal skullcap for epilepsy, there is insufficient reliable information about the clinical effects of Baikal skullcap for this purpose.
• Hand, foot, and mouth disease. It is unclear if intravenous Baikal skullcap is beneficial in patients with hand, foot, and mouth disease. Details: Low-quality observational research in children hospitalized with severe hand, foot, and mouth disease has found that children who are given Baikal skullcap intravenously as a Tanreqing injection 0.3-0.5 mL/kg once daily have a shorter duration of fever, oral ulcers, and rash, as well as reduced viral load, when compared with those given ribavirin 10 mg/kg once daily (96281). The validity of these findings is limited by the retrospective nature of the study.
• Headache. Although there has been interest in using oral Baikal skullcap for headache, there is insufficient reliable information about the clinical effects of Baikal skullcap for this purpose.
• Hemorrhoids. Although there has been interest in using oral Baikal skullcap for hemorrhoids, there is insufficient reliable information about the clinical effects of Baikal skullcap for this purpose.

• HIV/AIDS. Although there has been interest in using oral Baikal skullcap for HIV/AIDS, there is insufficient reliable information about the clinical effects of Baikal skullcap for this purpose.
• Insomnia. Although there has been interest in using oral Baikal skullcap for insomnia, there is insufficient reliable information about the clinical effects of Baikal skullcap for this purpose.
• Osteoarthritis. Oral Baikal skullcap has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research shows that taking a specific product (Limbrel, Primus Pharmaceuticals) that contains flavocoxid, a blend of Baikal skullcap extract and catechu flavonoid extract, 500 mg once or twice daily for up to 12 weeks reduces symptoms of osteoarthritis of the knee when compared with baseline. These studies found no significant difference between this combination product and naproxen 440 mg once daily to 500 mg twice daily for reducing symptoms (17030,18012,92776). However, in 2017, the US Food and Drug Administration (FDA) formally requested the recall of all non-expired lots of this product due to the risk for liver and lung injury (106042). See the Adverse Effects section for more information.
• Peyronie disease. It is unclear if oral Baikal skullcap is beneficial in patients with Peyronie disease. Details: Observational research has found that taking oral Baikal skullcap root extract 150 mL twice daily for 6 months is associated with reduced time to disease stabilization, with an average reduction of 5 months, when compared with no treatment. In addition, 17% of patients taking Baikal skullcap had pain resolution and only 33% required surgical correction, compared with 0% and 58%, respectively, of control patients. In patients requiring surgery, taking Baikal skullcap did not appear to affect resolution; however, the study may have been inadequately powered to detect a difference between groups (105867).
• Prostate cancer. Although there has been interest in using oral Baikal skullcap for prostate cancer, there is insufficient reliable information about the clinical effects of Baikal skullcap for this purpose.
• Psoriasis. Although there has been interest in using oral Baikal skullcap for psoriasis, there is insufficient reliable information about the clinical effects of Baikal skullcap for this purpose.

• Gingivitis. Magnolia bark extract might modestly reduce gum bleeding and inflammation when added to gum or toothpaste. Details: One clinical study shows that chewing gum containing magnolia bark extract plus xylitol for 5 minutes three times daily for 30 days reduces gingival bleeding by 33%, compared with 24% after chewing gum containing xylitol alone (92459). Another clinical study in adults with gingivitis shows that using a fluoride toothpaste containing magnolia extract 0.3% twice daily reduces gingivitis severity by about 0.27 points on the gingival index after 3 months, compared to 0.15 points for patients using the toothpaste without magnolia extract (92464).

• Aging skin. Although there is interest in using topical magnolia for aging skin, there is insufficient reliable information about the clinical effects of magnolia for this purpose.
• Allergic rhinitis (hay fever). Although there is interest in using oral magnolia for hay fever, there is insufficient reliable information about the clinical effects of magnolia for this condition.
• Anxiety. Oral magnolia has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in healthy females with mild anxiety shows that taking a proprietary blend of magnolia and phellodendron bark extract (Relora, Next Pharmaceuticals), standardized to 1.5% honokiol and 0.1% berberine, 250 mg three times daily for 6 weeks reduces temporary feelings of stress-induced anxiety almost 2-fold when compared with placebo. However, taking this product does not seem to improve long-standing feelings of stress-induced anxiety (34246). It is unclear if this effect is due to magnolia, other ingredients, or the combination. Additionally, this study was funded by the supplement manufacturer.
• Dental plaque. It is unclear if oral magnolia is beneficial in patients with dental plaque. Details: Clinical research in adults with gingivitis shows that using a toothpaste containing 0.3% magnolia extract twice daily modestly reduces plaque severity by about 0.41 points on the mean plaque index after 3 months, compared to a 0.27 point reduction for patients using the toothpaste without magnolia extract (92464). While statistically significant, this improvement might not be clinically meaningful.
• Diabetes. Although there is interest in using oral magnolia for diabetes, there is insufficient reliable information about the clinical effects of magnolia for this condition.
• Headache. Although there is interest in using oral magnolia for headache, there is insufficient reliable information about the clinical effects of magnolia for this condition.
• Menopausal symptoms. Oral magnolia has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A moderate-sized clinical study in postmenopausal patients shows that taking a specific combination of magnolia, Vitex agnus-castus, soy isoflavones, vitamin D, and lactobacillus (Estromineral Serena Plus, Meda Pharma SpA) daily for one year decreases the frequency and intensity of hot flashes and improves sleep quality and the ability to fall asleep when compared with soy isoflavones alone (95031). Additionally, a small clinical study shows that taking this same product daily for one year improves vasomotor symptoms, mood disorders, somatic symptoms, sleep disorders, blood pressure, and glycemic control when compared to baseline (110708). However, the validity of these findings is limited by a lack of control group. Overall, it is unclear if the effects of this magnolia-containing product in postmenopausal patients are due to magnolia, other ingredients, or the combination.
• Obesity. Oral magnolia has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in overweight females who report stress eating shows that taking a specific product containing a combination of bark extracts of magnolia plus phellodendron (Relora, Next Pharmaceuticals, Inc.) 250 mg three times daily for 6 weeks seems to prevent weight gain, compared with a 1.5 kg weight gain in those taking placebo (14349). This finding is limited because differences between groups were not statistically compared. Furthermore, it's unclear if this product induces weight loss.
• Postpartum depression. It is unclear if oral magnolia tea is beneficial for preventing postpartum depression. Details: A small clinical study in healthy postpartum patients shows that drinking 1 cup of magnolia tea daily for 3 weeks may improve depressive symptoms and sleep efficiency when compared with usual care alone. Magnolia tea (plant part unspecified) was steeped in 300 mL of hot water for 12 minutes prior to consumption (105089).
• Stress. Oral magnolia has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small low-quality clinical trial in moderately stressed healthy adults shows that taking a proprietary blend of magnolia and phellodendron bark extract (Relora, Next Pharmaceuticals) 250 mg twice daily for 4 weeks improves overall mood and decreases stress when compared with placebo (94904). It is unclear if this effect is due to magnolia, other ingredients, or the combination. Additionally, this study was funded by the supplement manufacturer. More evidence is needed to rate magnolia for these uses.

• Bronchiectasis. A small clinical study in patients with bronchiectasis shows that taking serrapeptase 30 mg daily for 4 weeks significantly reduces frequency of cough and also seems to decrease sputum viscosity and neutrophil counts in sputum samples when compared with no treatment (13153).
• Chronic bronchitis. A small clinical study in patients with chronic bronchitis shows that taking serrapeptase 30 mg daily for 4 weeks significantly reduces frequency of cough and expectoration and also seems to decrease sputum viscosity and neutrophil counts in sputum samples when compared with no treatment (13153).
• Laryngitis. A clinical study in patients with acute or chronic ear, nose, or throat disorders, including laryngitis, shows that taking serrapeptase 10 mg three times daily reduces pain, secretions, difficulty swallowing, and body temperature after 3-4 days of treatment when compared with placebo (13152).
• Pharyngitis. A clinical study in patients with acute or chronic ear, nose, or throat disorders, including pharyngitis, shows that taking serrapeptase 10 mg three times daily reduces pain, secretions, difficulty swallowing, and body temperature after 3-4 days of treatment when compared with placebo (13152).
• Postoperative swelling. Serrapeptase has been evaluated for reducing facial swelling after a variety of procedures. A clinical study in patients undergoing maxillary antrostomy for empyema shows that taking serrapeptase 10 mg orally three times on the day before surgery, once in the evening after surgery, and three times daily for 5 days after surgery modestly reduces buccal swelling when compared with placebo (13151). In patients requiring removal of impacted mandibular third molars, a small clinical study in healthy adults suggests that taking serrapeptase 10 mg three times daily for 5 days improves postoperative trismus and swelling by the fourth postoperative day when compared with placebo; however, no difference in pain scores was observed (106013). The validity of these findings in limited by a lack of consistent comparison to baseline in both groups. Conversely, two other small studies in patients requiring removal of impacted mandibular third molars suggest that serrapeptase is less effective than dexamethasone or another proteolytic enzyme, consisting of trypsin, bromelain, and the flavonoid rutin, for improving swelling or facilitating wound healing (106011,106012). The validity of these findings is limited due to poor study methodologies.
• Rhinosinusitis. A clinical study in patients with acute or chronic ear, nose, or throat disorders, including rhinosinusitis, shows that taking serrapeptase 10 mg three times daily reduces pain, nasal secretions, nasal obstruction, and anosmia after 3-4 days of treatment when compared with placebo (13152). More evidence is needed to rate serrapeptase for these uses.

ALCOHOL (Ethanol) Interaction Rating = Minor Be watchful with this combination. Severity = Moderate •  Occurrence = Unlikely •  Level of Evidence = D Theoretically, Baikal skullcap might potentiate the sedative effects of alcohol.  Details 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 (6290,6291,33477). 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.

ANTICOAGULANT/ANTIPLATELET DRUGS Interaction Rating = Moderate Be cautious with this combination. Severity = High •  Occurrence = Possible •  Level of Evidence = D Theoretically, Baikal skullcap might increase the risk of bleeding when used concomitantly with anticoagulant and antiplatelet drugs.  Details 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 (33075). It is unclear if this effect is due to Baikal skullcap, other ingredients, or the combination.

ANTIDIABETES DRUGS Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = B Theoretically, concomitant use of Baikal skullcap with antidiabetes drugs might enhance blood glucose lowering effects.  Details Baicalein, a constituent of Baikal skullcap, has alpha-glucosidase inhibitory activity in vitro (6292). Animal research also suggests that Baikal skullcap enhances the antidiabetic effects of metformin (33408). 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) (101738). Until more is known, use cautiously.

ANTIHYPERTENSIVE DRUGS Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, concomitant use of Baikal skullcap with antihypertensive drugs might have additive effects and increase the risk of hypotension.  Details Animal research suggests that baicalein, a constituent of Baikal skullcap, might lower blood pressure (33374).

ANTITHYROID DRUGS Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, concomitant use of Baikal skullcap and antithyroid drugs may result in additive activity and increase the risk of hypothyroidism.  Details In an animal hyperthyroid model, Baikal skullcap improved levels of triiodothyronine (T3), thyroxine (T4), and thyroid stimulating hormone (TSH) (101736). The clinical significance of this effect is unclear.

CNS DEPRESSANTS Interaction Rating = Minor Be watchful with this combination. Severity = Moderate •  Occurrence = Unlikely •  Level of Evidence = D Theoretically, Baikal skullcap might cause additive therapeutic and adverse effects when used concomitantly with drugs with sedative properties.  Details 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 (6290,6291,33477). 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.

CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, Baikal skullcap may increase levels of drugs metabolized by CYP1A2 enzymes.  Details In vitro evidence suggests that constituents of Baikal skullcap inhibit the activity of CYP1A2 (33346,33484). This effect has not been reported in humans.

CYTOCHROME P450 2C19 (CYP2C19) SUBSTRATES Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, Baikal skullcap might increase levels of drugs metabolized by CYP2C19 enzymes.  Details In vitro evidence suggest that wogonin, a constituent of Baikal skullcap, modestly inhibits the activity of CYP2C19 enzymes (33484). This effect has not been reported in humans.

ESTROGENS Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, concomitant use of large amounts of Baikal skullcap might interfere with hormone replacement therapy, due to competition for estrogen receptors.  Details In vitro evidence suggests that Baikal skullcap has estrogenic activity (16061).

LITHIUM Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, Baikal skullcap might reduce lithium excretion and increase serum levels of lithium.  Details Baikal skullcap is thought to have diuretic properties, which may reduce lithium excretion (5541). The dose of lithium might need to be decreased.

ORGANIC ANION-TRANSPORTING POLYPEPTIDE SUBSTRATES (OATP) Interaction Rating = Minor Be watchful with this combination. Severity = Mild •  Occurrence = Possible •  Level of Evidence = B Theoretically, Baikal skullcap might alter the levels and clinical effects of OATP substrates.  Details 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 (16395). Baikal skullcap might also affect other OATP1B1 substrates (16396,16397,16398).

P-GLYCOPROTEIN SUBSTRATES Interaction Rating = Minor Be watchful with this combination. Severity = Mild •  Occurrence = Possible •  Level of Evidence = D Theoretically, Baikal skullcap might increase levels of drugs transported by P-glycoprotein.  Details In vitro and animal research suggests that baicalein, oroxylin A, and wogonin, constituents of Baikal skullcap, can inhibit P-glycoprotein (33372,33395,33440,33462). This effect has not been reported in humans.

ANTICOAGULANT/ANTIPLATELET DRUGS Interaction Rating = Moderate Be cautious with this combination. Severity = High •  Occurrence = Possible •  Level of Evidence = D Theoretically, magnolia might have additive effects and increase the risk of bleeding when used with anticoagulant or antiplatelet drugs.  Details In vitro research shows that the chemicals magnolol and honokiol, isolated from magnolia bark, inhibit platelet aggregation that is experimentally induced by collagen and arachidonic acid. However, they do not inhibit platelet aggregation that is induced by adenosine diphosphate, platelet-activating factor, or thrombin (18273). This interaction has not been reported in humans.

CNS DEPRESSANTS Interaction Rating = Moderate Be cautious with this combination. Severity = High •  Occurrence = Possible •  Level of Evidence = D Theoretically, concomitant use of large doses of magnolia bark and CNS depressants might have additive effects.  Details In vitro and animal research shows that constituents extracted from magnolia bark, especially honokiol and magnolol, have sedative effects. These effects may be due to the inhibition of catecholamine release and modulation of gamma-aminobutyric acid-A (GABA-A) receptors (11946,11952).

General ...Orally, Baikal skullcap seems to be well-tolerated. There is currently a limited amount of information on the adverse effects of intravenous and topical Baikal skullcap.
Most Common Adverse Effects:
Orally: Abdominal pain, constipation, diarrhea, erythema, nausea, pruritus, and vomiting.
Intravenously: Skin reactions.
Topically: Dermatitis.
Serious Adverse Effects (Rare):
Orally: Hepatotoxicity and hypersensitivity pneumonitis have been reported with a specific combination product (Limbrel, Primus Pharmaceuticals) containing extracts of Baikal skullcap and catechu.

Cardiovascular ...Orally, in a small clinical study evaluating the safety of baicalein, a constituent of Baikal skullcap, in healthy adults, elevated triglyceride levels occurred in 1 of 10 patients who received 400 mg every 8 hours and 2 of 10 patients treated with 600 mg every 8 hours, compared with 0 of 10 patients who received 200 mg every 8 hours and 0 of 6 patients who received placebo. Triglyceride elevations were considered mild and resolved after discontinuation (110023).

Dermatologic ...Orally, taking Baikal skullcap may cause erythema and pruritus (105867). Intravenously, Baikal skullcap as part of a Tanreqing injection has been associated with reports of skin reactions in some pediatric patients (96281).
Topically, several cases of allergic contact dermatitis have been reported after applying sunscreen containing Baikal skullcap extract (105869,105870). Allergic contact dermatitis has also been reported after applying a facial cream (Resveratrol BE, Skinceuticals) containing Baikal skullcap root extract 0.5% and resveratrol 1%. Patch testing identified a positive reaction to both ingredients (110024). Baikal skullcap-induced dermatitis appears to respond to treatment with a topical corticosteroid and calcineurin inhibitor (105870).

Gastrointestinal ...Orally, use of Baikal skullcap has been associated with epigastric pain, abdominal pain, constipation, diarrhea, nausea, and vomiting (101738,105867).

Hepatic ...A specific combination product (Limbrel, Primus Pharmaceuticals) containing flavocoxid, a mixture of Baikal skullcap flavonoid extract and catechu extract, has been linked to several reports of acute liver damage. There have been at least five published reports of liver damage associated with this product. In all cases, the patients were females aged 54-68 years taking doses of 250-500 mg twice daily for 1-3 months. Signs and symptoms included jaundice, pruritus, abdominal pain, fever, rash, and elevated serum bilirubin and liver transaminase levels. All patients fully recovered and levels normalized within 3 months after discontinuation (18009,96282). In addition to these published case reports, approximately 30 liver-related adverse events have been reported to the manufacturer of this product (18009). The mechanism of hepatotoxicity is unclear (18009,18010); it is estimated that the incidence of hepatotoxicity with this product is around 1 in 10,000, although the actual incidence is unknown (18010). In 2017, the US Food and Drug Administration (FDA) formally requested the recall of all non-expired lots of this product due to the risk for liver and lung injury (106042). It is unclear if these effects were due to Baikal skullcap, catechu, or the combination.
Hepatotoxicity has also been reported in two patients taking a specific dietary supplement (Move Free Advanced, Reckitt Benckiser) containing Baikal skullcap, black catechu, glucosamine, chondroitin, and hyaluronic acid (33460) and in a patient taking Baikal skullcap, elderflower, horseradish, and white willow (101737). The investigators determined that the hepatotoxicity was likely caused by Baikal skullcap in these cases (33460,101737). Additionally, cases of liver injury are reported in 4 of 37 patients taking various Kampo formulations containing Baikal skullcap and other herbs daily. Patients presented with elevated liver function tests 7 to 38 days after consumption (112179). It is unclear if this adverse effect is from Baikal skullcap, other ingredients, or the combination.
In a small study evaluating the safety of baicalein, a constituent of Baikal skullcap, in healthy adults, liver transaminase elevations occurred in 2 of 10 patients who received 400 mg every 8 hours for 6 days, compared with 0 of 6 patients who received placebo. No patients receiving either 200 mg or 600 mg every 8 hours experienced liver transaminase elevations. The elevations were considered mild and resolved after discontinuation (110023).

Pulmonary/Respiratory ...A specific combination product (Limbrel, Primus Pharmaceuticals) containing flavocoxid, a mixture of Baikal skullcap flavonoid extract and catechu extract, has been linked to several reports of hypersensitivity pneumonitis. Symptoms include fever, chills, headache, cough, chronic bronchitis, shortness of breath, weight loss, and fatigue. In 2017, the US Food and Drug Administration (FDA) formally requested the recall of all non-expired lots of this product due to the risk for liver and lung injury (106042). It is unclear if these effects were due to Baikal skullcap, catechu, or the combination.

Renal ...Orally, in a small clinical study evaluating the safety of baicalein, a constituent of Baikal skullcap, in healthy adults, proteinuria of undefined severity occurred in 1 of 10 patients who received 200 mg every 8 hours for 6 days, 3 of 10 patients who received 400 mg every 8 hours for 6 days, and 5 of 10 patients who received 600 mg every 8 hours for 6 days, compared with 1 of 6 patients who received placebo. The proteinuria was considered mild and resolved after discontinuation (110023).

General ...Orally, magnolia seems to be well tolerated.
Most Common Adverse Effects:
Topically: Contact dermatitis.

Dermatologic ...Topically, magnolia bark has been associated with reports of allergic contact dermatitis (92463,92468,95030,110709). In several cases, the use of anti-aging facial creams containing magnolia bark extract was associated with allergic contact dermatitis of the face (92463,92468,95030). In one case, the use of a vaginal gel containing magnolia bark extract was associated with allergic contact dermatitis of the vulva (110709). Symptoms typically resolve with the use of topical corticosteroids and discontinuation of magnolia bark extract (95030,110709). Patch testing suggests that the magnolia bark extract constituents magnolol and honokiol are responsible for this adverse effect (110709).

Endocrine ...In a clinical trial of an oral combination product containing extracts of magnolia and phellodendron, one patient reported thyroid dysfunction (14349). However, it's not known if this side effect is related to magnolia or some other factor.
