2 Known Drug Interactions — Some May Be Serious
1 Moderate1 Mild
This herb may interact with medications you are taking. Review the interactions table below and consult your healthcare provider before use.
What is a herb–drug interaction?
A herb–drug interaction happens when a plant or supplement changes how a medication works in your body — making it stronger, weaker, or more likely to cause harm. Herbs contain active compounds that can speed up or slow down the enzymes and transporters your body uses to process drugs.
Why it matters
•St. John's Wort can make birth control, antidepressants, and blood thinners less effective.
•Garlic can increase bleeding risk with warfarin and other blood thinners (also ginkgo, ginger, and turmeric).
•Kava can amplify sedation when taken with anxiety or sleep medications (also valerian).
The risk is highest for older adults, anyone taking several medications, and people with chronic conditions.
Always tell your doctor and pharmacist about every herb and supplement you take — and check below before combining.
Eleuthero may have mild effects on platelet function that warrant monitoring with warfarin.
This list reflects a curated subset of documented interactions and is not exhaustive. The absence of a drug here is not proof that it is safe to combine. Always confirm with a pharmacist or healthcare provider.
How does Eleuthero work as an adaptogen in the body?
Eleuthero contains active compounds called eleutherosides, which are believed to modulate the body's stress response through the hypothalamic-pituitary-adrenal (HPA) axis. These compounds may help regulate cortisol levels and support cellular energy metabolism. Research suggests eleutherosides also possess immunomodulatory and anti-inflammatory properties. Unlike stimulants, Eleuthero appears to work gradually, supporting the body's natural resistance to physical, mental, and environmental stressors over time. Evidence level: C.
Does Eleuthero interact with any prescription medications?
Yes, Eleuthero may interact with several medications. It can potentially enhance the effects of anticoagulants like warfarin, increasing bleeding risk. Eleuthero may also interact with heart medications, including digoxin and antihypertensives, affecting their efficacy. Due to its potential effects on blood glucose, it may enhance the effects of diabetes medications. Those taking immunosuppressants should avoid Eleuthero as it may counteract these drugs. Always consult a healthcare provider before combining Eleuthero with prescription medications.
What is the recommended daily dosage of Eleuthero?
The typical adult dosage of Eleuthero is 300-1200mg of dried root extract daily, or 2-4ml of tincture taken 2-3 times daily. Standardized extracts containing eleutherosides are often preferred for consistent potency. Eleuthero is generally taken for 6-8 weeks followed by a 1-2 week break to maintain effectiveness. Dosage may vary based on the specific product and intended use. Evidence level: C. Always follow manufacturer guidelines or consult a qualified herbal practitioner.
Is Eleuthero safe to take during pregnancy and breastfeeding?
Eleuthero is considered unsafe during pregnancy and should be avoided. There is insufficient reliable evidence regarding its safety during breastfeeding, so it is not recommended while nursing. The herb may stimulate uterine contractions and affect hormone levels, posing potential risks to fetal development. Pregnant and breastfeeding women should consult their healthcare provider before using any herbal supplements. Evidence level: Traditional use contraindicates use in pregnancy.
What is Eleuthero used for and does it work?
Eleuthero is primarily used as an adaptogen to help the body resist physical and mental stress. Traditional and research evidence suggests it may enhance stamina, support immune function, and improve mental performance under fatigue. It was extensively studied in Russia for enhancing athletic performance and was used by Russian cosmonauts. Some evidence suggests it may help reduce fatigue and support recovery from illness. Evidence level: C. Benefits are typically noticed after several weeks of consistent use.
What are the side effects of taking Eleuthero?
Common side effects of Eleuthero include insomnia, irritability, headache, anxiety, and diarrhea, particularly when taken in high doses or late in the day. These effects are typically mild and resolve when dosage is reduced or discontinued. Eleuthero may also cause increased blood pressure in some individuals. Those with hypertension, autoimmune conditions, or hormone-sensitive conditions should avoid use. Side effects are more likely with long-term continuous use without breaks.

Summary
Eleutherococcus senticosus, also known as Siberian ginseng, is a plant adaptogen used to enhance the body's resistance to stress and improve physical and mental endurance [PMID:34445021, PMID:40572479].
Background
Eleutherococcus senticosus (ES), also referred to as Acanthopanax senticosus or Siberian ginseng, is a medicinal plant native to Northeast Asia [PMID:40572479, PMID:30000865]. It belongs to the Araliaceae family and is distinct from true ginseng [PMID:30000865, PMID:30678313].
Traditional uses
ES is used in traditional Chinese, Korean, and Japanese medicine, where the rhizomes and bark are utilized to enhance stress resistance, boost mental and physical endurance, and strengthen the immune system [PMID:40572479]. It has been used for recovery from illness, physical weakness, and memory impairment [PMID:34445021].
Active compounds
Bioactive compounds include eleutherosides (specifically eleutheroside B/syringin and eleutheroside E/syringaresinol), lignans, saponins, flavonoids, polysaccharides, acanthosides, phytosterols, triterpene saponins, and 5'-O-caffeoylquinic acid isomers [PMID:40572479, PMID:30000865, PMID:25005060].
Mechanism of action
Mechanisms are complex and involve multiple molecular pathways [PMID:38398618]. Reported effects include anti-oxidative damage, anti-inflammation, neurotransmitter modulation, improvement of neuronal growth, and anti-apoptosis [PMID:35844057]. Specifically, Eleutheroside A may inhibit PI3K/AKT1/mTOR-mediated glycolysis in myeloid-derived suppressor cells (MDSCs) [PMID:40409102], and the herb may induce ferroptosis in glioblastoma cells [PMID:40704405].
Clinical evidence
Evidence CEndurance Performance
Rigorous research protocols show no benefit of ES supplementation (up to 1200 mg/d) on cardiorespiratory fitness, fat metabolism, or endurance performance [PMID:15902991].
Evidence CNeurological Disorders
Proposed as a therapeutic modulator for neurodegenerative conditions such as Alzheimer's and Parkinson's disease due to neuroprotective properties [PMID:40572479, PMID:18488457].
Evidence DCancer
In vitro and in vivo experiments suggest inhibitory effects on malignant tumors of the lung and liver [PMID:27852123] and inhibition of glioblastoma cell proliferation and migration [PMID:40704405].
Evidence CGeneral Adaptogenic Use
Used to increase endurance and improve memory, though no good human evidence supports these uses [PMID:30000865].
Safety & adverse effects
Generally well tolerated, but may increase blood pressure, increase bleeding, and increase blood sugar [PMID:30000865]. Breast tenderness has been reported [PMID:30000865]. It has been listed as a product with potential hepatotoxicity in reports of Traditional Chinese Medicine induced liver injury [PMID:26357619].
Pregnancy & lactation
No data exist on the safety and efficacy of eleuthero in nursing mothers or infants [PMID:30000865].
Evidence summary
The evidence is primarily based on reviews and in vitro/animal studies (Level C and D). Clinical evidence for physical performance is contradictory or negative, and many claimed therapeutic effects lack robust human clinical trial support.
