Stephania root contains tetrandrine and fangchinoline, alkaloids that act as calcium channel blockers, helping relax blood vessels and reduce blood pressure. These compounds also demonstrate anti-inflammatory effects by inhibiting inflammatory mediators and modulating immune cell activity. The herb's diuretic properties promote fluid excretion through the kidneys, making it useful for edema. Evidence Level: C.
Does Stephania root interact with any medications?
Stephania root may interact with immunosuppressant medications, as its immunomodulatory compounds like tetrandrine could interfere with their therapeutic effects. Due to its hypotensive properties, it may enhance the effects of antihypertensive drugs, potentially causing blood pressure to drop too low. Always consult a healthcare provider before combining Stephania with prescription medications. Evidence Level: C/Traditional.
What is the recommended dosage for Stephania root?
The typical adult dosage for Stephania root is 5-10 grams as a decoction when prepared traditionally, or approximately 300mg of standardized extract taken twice daily. Dosage may vary based on the specific condition being treated and individual factors. Always follow product label instructions or consult a qualified herbalist for personalized dosing guidance. Evidence Level: Traditional.
Is Stephania root safe during pregnancy?
Stephania root is considered unsafe during pregnancy and should be avoided. Traditional Chinese Medicine contraindicates its use in pregnant women. Additionally, there is a critical safety concern regarding potential adulteration with Aristolochia species, which contain nephrotoxic and carcinogenic compounds. Pregnant women should never use Stephania root without explicit guidance from a qualified healthcare provider. Evidence Level: Traditional.
Can Stephania root help with arthritis and joint pain?
Stephania root has been used traditionally in Chinese Medicine to treat wind-damp joint pain and swelling associated with arthritis. Research suggests its active compounds, particularly tetrandrine, possess anti-inflammatory properties that may help reduce joint inflammation and pain. However, clinical evidence remains limited (Level C), and more rigorous studies are needed to confirm efficacy for arthritis treatment.
What are the side effects of Stephania root?
Common side effects of Stephania root may include gastrointestinal discomfort such as nausea or stomach upset. Due to its blood pressure-lowering effects, some individuals may experience hypotension, particularly when taking other antihypertensive medications. Proper botanical identification is essential, as confusion with toxic Aristolochia species has caused serious kidney damage in documented cases. Evidence Level: C/Traditional.

Résumé
Stephania Root (Stephania tetrandra) is a traditional Chinese medicine used for its analgesic, diuretic, and antihypertensive properties [PMID:26899361], primarily characterized by the presence of bisbenzylisoquinoline alkaloids [PMID:35432428].
Contexte
Stephania tetrandra S. Moore, known in Chinese as 'Fen Fang Ji' or 'Fangji', is a plant distributed across tropical and subtropical regions of Asia and Africa [PMID:32336965, PMID:32497674].
Usages traditionnels
It is used in traditional Chinese medicine to treat arthralgia caused by rheumatism, wet beriberi, dysuria, eczema, inflamed sores [PMID:32336965], edema [PMID:32497674], hypertension, asthma, tuberculosis, dysentery, hyperglycemia, malaria, cancer, and fever [PMID:26899361].
Composés actifs
The primary active components are bisbenzylisoquinoline alkaloids, most notably tetrandrine [PMID:26899361, PMID:39151800], fangchinoline [PMID:41242135], and coclaurine [PMID:39458997]. Other isolated compounds include limacine, N-trans-Feruloyltyramine, and Stephtetrandrine A-D [PMID:34348525].
Mécanisme d'action
Tetrandrine acts as a calcium channel blocker [PMID:26899361] and interacts with M receptors for cardiovascular effects [PMID:12466045]. It modulates signaling pathways including reactive oxygen species (ROS), autophagic flux, the caspase pathway, and targets SIRT5 to induce ER stress in melanoma cells [PMID:26899361, PMID:39850232]. Coclaurine inhibits EFHD2, downregulating the NOX4-ABCC1 signaling pathway [PMID:39458997]. Fangchinoline targets FAU to induce senescence in circulating tumor cells [PMID:41242135].
Preuves cliniques
Preuve BHypertension
Tetrandrine has been found effective in clinical trials for the treatment of hypertension [PMID:26899361, PMID:12466045].
Preuve BSilicosis and Lung Cancer
Clinical trials indicated tetrandrine is effective against silicosis, inflammation, and lung cancer without toxicity [PMID:26899361].
Preuve CDiabetic Kidney Disease (DKD)
S. tetrandra demonstrates value in preventing and treating DKD by regulating inflammatory responses, antagonizing oxidative stress, and improving glomerular endothelial function [PMID:41031161].
Preuve DNephrotic Syndrome
A herbal pair of S. tetrandra and Astragalus membranaceus reduced serum triglycerides, total cholesterol, IL-6, BUN, and urinary protein in rat models [PMID:36678585].
Preuve DPulmonary Fibrosis
Tetrandrine alleviated pulmonary fibrosis in mice by regulating lung microbial communities and ameliorating alveolar epithelial cell senescence [PMID:39510818].
Preuve D
Sécurité et effets indésirables
While tetrandrine is described as minimally toxic [PMID:39510818], some reviews list S. tetrandra as a source of renal toxic alkaloids [PMID:26670420]. A critical safety concern is the frequent adulteration or substitution of S. tetrandra with the nephrotoxic and carcinogenic Aristolochia fangchi [PMID:26632529, PMID:18404356]. This substitution has led to 'Chinese-herb nephropathy', characterized by progressive interstitial fibrosis, end-stage renal disease, and urothelial carcinoma [PMID:12505369, PMID:10841870, PMID:9090927].
Synthèse des preuves
Evidence ranges from high-level clinical trial reports for hypertension and silicosis to preclinical animal and cellular studies for oncology and renal protection. A significant portion of the literature focuses on the critical need for quality control to prevent toxic substitution with Aristolochia species.
