Hydrastis 6X HPUS
Also known as: Goldenseal, Hydrastis, Hydrastis canadensis
Overview
Hydrastis canadensis, commonly known as goldenseal, is a perennial herb native to North America, traditionally used by Indigenous peoples for various medicinal purposes. The 6X HPUS designation refers to a homeopathic dilution (1 part in 10^6), indicating a very low concentration of the active herb in the preparation. Goldenseal root and rhizome extracts contain bioactive alkaloids such as berberine and hydrastine, which are thought to contribute to its pharmacological effects. It is used primarily for its purported antimicrobial, anti-inflammatory, and digestive health applications, as well as in some homeopathic treatments. Research on goldenseal extracts is moderately mature, but high-quality randomized controlled trials (RCTs) and systematic reviews specifically on Hydrastis 6X HPUS are limited, making its clinical efficacy uncertain.
Benefits
The primary benefits of goldenseal extracts are attributed to their antimicrobial and anti-inflammatory effects, largely due to alkaloids like berberine and hydrastine. A case series suggested that Hydrastis 6X HPUS may help prevent catheter encrustation and malodorous urine in patients with neurogenic bladder dysfunction, indicating potential urinary tract benefits, particularly in patients with spinal cord injury using long-term catheters. However, this evidence is limited to a small, uncontrolled observational study, lacking statistical analysis or control groups. Goldenseal extracts containing berberine have also shown potential hypoglycemic and hypolipidemic effects, but these are not specific to the 6X HPUS dilution. No large RCTs or meta-analyses with quantified effect sizes for Hydrastis 6X HPUS are available, and the clinical significance of observed benefits in the case series is not well-established.
How it works
The primary bioactive compounds in goldenseal, berberine and hydrastine, exert their effects through several mechanisms. They are known to have antimicrobial properties by disrupting bacterial cell walls and inhibiting microbial enzymes. Berberine also modulates inflammatory pathways, potentially by influencing cytokine production and signaling pathways. Additionally, berberine may affect glucose and lipid metabolism, contributing to potential hypoglycemic and hypolipidemic effects. Pharmacokinetic studies indicate that berberine has low oral bioavailability, meaning only a small fraction is absorbed into the bloodstream, though it can accumulate with repeated dosing. The homeopathic 6X dilution, being highly diluted, likely contains minimal amounts of these alkaloids, raising questions about direct pharmacological effects at this potency.
Side effects
Goldenseal extracts are generally considered safe for short-term use at recommended doses. However, some reports indicate potential hepatotoxicity (liver damage) and neurotoxicity (nerve damage) with prolonged or high-dose use of concentrated extracts. For the highly diluted Hydrastis 6X HPUS, a case series reported no side effects or renal impairment over extended use, suggesting a higher safety profile at this homeopathic potency. Drug interactions are a significant concern, especially with goldenseal extracts containing berberine, due to its effect on cytochrome P450 enzymes and P-glycoprotein. These interactions can alter the metabolism and effectiveness of many other drugs, including those for cardiovascular conditions, diabetes, and certain antibiotics. Contraindications include pregnancy and breastfeeding due to insufficient safety data, as berberine can cross the placental barrier and may stimulate uterine contractions. Individuals with liver disease, kidney disease, or autoimmune conditions should use goldenseal with caution.
Dosage
For homeopathic Hydrastis 6X HPUS, specific dosing guidelines are not well-established in clinical trials and typically follow homeopathic practice, which involves very low and individualized doses. The case series that reported benefits used a low, unspecified homeopathic dose over several months. For goldenseal extracts standardized to berberine, doses in clinical studies range from 500 mg to 1500 mg daily, often divided into multiple doses. However, these dosages are for concentrated extracts and are not directly applicable to the highly diluted 6X HPUS preparations. Absorption of berberine from goldenseal is generally low; co-administration with absorption enhancers (e.g., piperine) may improve its bioavailability. There are no established upper limits or safety thresholds specifically for Hydrastis 6X HPUS due to its highly diluted nature, but caution is advised with any goldenseal product, especially concentrated forms.
FAQs
Is Hydrastis 6X HPUS effective?
Evidence for Hydrastis 6X HPUS is limited to case reports and lacks robust randomized controlled trials; therefore, its clinical efficacy remains uncertain and requires further research.
Is it safe?
At homeopathic dilutions, Hydrastis 6X HPUS is generally considered safe with minimal reported side effects. However, caution is advised with higher doses or concentrated goldenseal extracts due to potential toxicities.
How long until effects appear?
Case reports suggest that observable benefits from Hydrastis 6X HPUS may require several months of consistent use, indicating a gradual onset of effects.
Can it interact with medications?
Yes, especially concentrated goldenseal extracts containing berberine can interact with medications metabolized by liver enzymes (cytochrome P450) or P-glycoprotein, altering drug levels.

- https://pmc.ncbi.nlm.nih.gov/articles/PMC8322421/ – This case series by Pannek et al. (2021) investigated the use of Hydrastis 6X HPUS in four patients with neurogenic bladder using long-term catheters. The study reported that the homeopathic preparation helped prevent catheter encrustation and malodorous urine over several months of treatment without any reported side effects or renal impairment. However, the study's limitations include its small sample size, lack of a control group, and observational design, which limit the generalizability and statistical significance of the findings.
- https://pubmed.ncbi.nlm.nih.gov/32683037/ – This systematic review on goldenseal alkaloids (2020) summarized the pharmacological activities of goldenseal and its key alkaloids, berberine and hydrastine. It highlighted their antimicrobial, anti-inflammatory, and metabolic effects observed in various studies. The review emphasized the need for large-scale randomized controlled trials to confirm the clinical efficacy and safety of goldenseal, particularly noting the absence of specific data on highly diluted homeopathic potencies like 6X HPUS.
- https://rex.libraries.wsu.edu/view/pdfCoverPage?instCode=01ALLIANCE_WSU&filePid=13413327070001842&download=true – This pharmacokinetic study by Nguyen et al. (2021) investigated the effects of chronic goldenseal intake on drug metabolism in healthy adults. The research found that goldenseal significantly altered the metabolism of midazolam, a probe substrate for certain liver enzymes, indicating a potential for drug interactions. This suggests that goldenseal, particularly its active alkaloids, can influence the pharmacokinetics of other medications, although this study was not focused on the 6X HPUS dilution.
